Glass Fibers and Fiberglass Fabrics Information

Glass fibers and fiberglass fabric consist of bulk, chopped fibers or continuous strands of glass. Glass fibers and fiberglass fabric is used in reinforcing plastics and composites as well as other specialized electrical and thermal applications. Fiberglass cloth is frequently used to reinforce other plastic materials. Glass fiber reinforced plastic (GRP) or glass fiber reinforced epoxy (GRE) are commonly called fiberglass.


The glass fiber used to create fiberglass material is made by extruding very thin strands of silica-based monofilament. Glass is a unique amorphous solid, meaning it doesn’t have an underlying crystalline structure in the solid state, but rather behaves like a very viscous liquid. Glass fiber lends itself to woven fabric because the thin fibers can easily bend. Fabric made of glass fibers has high tensile strength, dimensional stability, high heat and fire resistance, as well as resistance to many chemical compounds. Fiberglass fabric is also used to dissipate heat, and has electrical properties that make it useful in electronic components.



Glass fibers and fiberglass fabrics are commonly used in composite construction, including materials used in boat building. Light weight fiberglass cloth is used with a resin to produce a waterproof surface. Heavier woven fiberglass fabric can be used for greater strength and rigidity.


Glass fibers and fiberglass fabrics are also used to create combination or specialty fabrics. Glass fibers and fiberglass fabric may be combined with carbon fiber or aramid fibers to make laminates and moldable fabrics for canoes, kayaks, and other high strength, low weight applications.



Glass fibers and fiberglass fabrics must adhere to certain standards and specifications to ensure proper design and functionality.

A Wonder in the Materials World: Stainless Steel Sheet

Material scientists have created stainless steel, the most versatile alloy which can be seen in its many applications because of its corrosion resistant properties


The introduction of a minimum of 12% chromium into the steel alloy renders it corrosion resistant. This resultant product is called stainless steel sheet. There are many grades according to the alloy content and they are named variously as austenitic, martensitic, ferritic, precipitation hardening, super and duplex alloys.


Popular Grades of Stainless Steel


Austenitic grades of alloys which are stainless and non-magnetic. These cannot be hardened by heat treatment. Commonly used austenitic alloys are iron-chromium-nickel steels. The common grades are the 300 series which are used for their stainless properties and unusually good mechanical properties. The basic grade of this series is the 304. The L grades of this series are the low carbon grades (as in 304l) which provide extra corrosion resistance after welding. The carbon content is kept at 0.03% or less to avoid carbide precipitation. Higher carbon content is useful when the metal is subjected to very high temperatures and has to retain its strength.


The two other popular grades in this series are 316 and 317


Martensitic Grades of Alloys which are corrosion resistant and amenable to hardening by heat treatment. These are chromium steels with no nickel content. They are magnetic. The most common grades in this are the basic 410 and 420, where 420 has increased carbon more than 410 to improve its mechanical properties


Ferritic Grades – Even more corrosive resistant than the martensitic grades, these are highly resistant to cracking due to stress related corrosion. These are also magnetic with only chromium and no nickel. They are considered inferior to austenitic grades, but superior to martensitic grades. 430 is the base grade, which is used commonly.


Physical Forms


They come in a variety of forms like coils, sheets, bars and plates




For its easy maintenance and corrosion resistant properties, stainless steel sheets find diverse applications in:


  1. Modern architecture


  1. Food processing industry


  1. Industrial uses, such as chemical and fuel tankers, chemical plants and petrochemical plants, pharmaceutical industries (for hygienic environment)


What are Stainless Steel Sheets Standards?


There are many world recognized standards of stainless steel sheets which categorize the stainless steel sheets into different grades as explained above. These may be voluntary grading agencies, country specific agencies or associations of steel producing companies in a particular country. Sometimes any grade of steel marketed by a company will mention different standards of grading having been applied to it.


How the Demand for Stainless Steel Plated is satisfied?


There are suppliers worldwide who have industry specific grades available for their customers. They have websites and can be contacted easily for further details through a ‘contact us’ webpage. They are also present in social media like Facebook and Twitter. It does not matter if the supplier is from another country in this era of globalization. There is not much difference in the way of doing business.


Future of the Stainless Steel Sheet Industry


Since stainless steel sheet is such a versatile material, there is ongoing research and more grades are added to the existing ones as they are developed and tested, having unique qualities and different applications


The invention and countless applications of stainless steel sheet is a real wonder in the materials world and the future of the steel industry is bright with companies worldwide engaged in supply of this wondrous alloy.

How do Pilot Operated and Direct Operated Solenoid Valves Work?

What are Solenoid Valves?

A solenoid valve is an electro-mechanical valve that is used to control the flow of liquid or gas. The solenoid starts by converting an electrical signal into a mechanical movement. The signal is then sent to a coil and the movement then occurs inside of the valve. Solenoid valves are usually be described as pilot operated or direct operated/acting.


Pilot Operated Solenoid Valves

2 way pilot operated solenoid valves have two chambers separated by a diaphragm. The upper chamber is connected to upstream through a pilot hole in either the cover or diaphragm. The media exerts a pressure that acts on the upper side of the diaphragm and keeps the valve closed. When the coil is charged the core lifts off the orifice seat allowing the operating chamber to de-pressurize. The thrust of the upstream pressure under the diaphragm continues, lifting the diaphragm and opening the valve.


Pilot operated solenoid valves only operate with a suitable upstream pressure differential and do not operate at zero pressure. Also a minimum pressure differential across the valve is required to keep them open or closed. Pilot operated solenoid valves can provide high flow rates at high pressures with lower power consumption.


Direct Acting Solenoid Valves

Direct acting solenoid valves do not use a diaphragm, their seal is part of the moving core. Two way NC direct acting solenoid valves have a spring that holds the core against the seal. When the coil is charged the spring is overcome and the seal is lifted from the orifice seat thus opening the valve and allowing the media to pass through the valve.


Two way NO direct acting solenoid valves have a fixed core which usually in the bottom section of the armature tube. The armature is located in the upper part of the valve. A stem passes through the fixed core and is coupled to the seal. This is held off the seal by means of a spring and makes a seal when the coil is energized, thus closing the valve.


Three way direct acting solenoid valves work in almost the same way as a two way direct acting solenoid valve. The fixed core has an exhaust orifice running through it. The plunger has an upper seal and lower seal allowing flow to or from either the body seat or exhaust.


Direct acting solenoid valves are used when there is no line pressure applied. Typical applications would include a cleaning line when a pump supplies bursts of water through the line. A direct operated solenoid valve would remain closed, even when no pressure is being applied (i.e. in between the busts of water). This is in contrast to a pilot operated valve, which requires some pressure for the valve to stay closed.

What is a Die Sinker EDM Machine?

A die sinker EDM machine is an industrial machine, used to create highly precise forms and structures onto metal plates. A die sinking EDM machine is used to manufacture moulds and templates, as well as press and injection moulds. The mass production of metal reforming, or plastic products with consistent high quality and highly precise dimensions, would only be possible with a die sinker EDM machine.


Highly Precise Cutting Using Sparks and Arcs

Since the invention of electricity, it is known that sparks can leave marks on metal surfaces. The cutting effect of electric arcs was only first researched in detail in 1770 by the British scientist, Joseph Priestley. The idea of finding a practical use for it arose over 150 years later. Two brothers from Russia, B.R. and N.I. Lazarenko, researched electric discharging as a new processing method for metal surfaces. These basic technological principles for utilization that they developed are still valid today.


Wire Erosion Discharge Machining – The Opposite of Welding

In principle, erosion is very similar to build-up welding. However, the erosion process is done backwards. During welding, material is applied to a workpiece and during erosion, the material is (with help of a conductor and high levels of electricity) evaporated off the workpiece. Using defined intervals and transitions, the metal is broken out of the block of steel with micrometer levels of precision. Despite the small work stages, spectacular sparks are still visible. The accumulation of sparks has no influence, however, on the precision of the surface area. The principle behind this is very simple: different polarized potential is applied to the workpiece and the conductor.


The evaporation of the material always takes place, where the distance between the electrodes is the smallest. That is how contours are produced, that cannot be exceeded in terms of precision. Burn and corrosion damages to the conductor and the workpiece can be avoided, as long as the erosion process completely takes place in a conductive, liquid medium. Die sinking should not be performed by assistants or temporary workers. It is essential to have extensive training and a lot of experience, in order to successfully manufacture workpieces through die sinking. For this reason, working with die sinker EDMs should only be conducted by specialists.


What can be Produced Using Die Sinking?

When working with a metal workpiece, the processing options with a die sinker EDM machine are unlimited. The erosion conductor can be moved in every direction using its 5 axel head. This freedom of movement allows for the processing of highly complex forms. Die sinker EDM machines are therefore much more efficient than CNC-milling machines. The erosion process is contact-free, which means that expensive drilling, milling or rotating tools are not needed.


Even pressing and punching tools are generally made out of specifically strong steel that resists machining operations. With normal CNC-processes, this process will wear out and ruin the tools and machines. With the contact-free erosion process, the hardness and firmness of a steel work tool plays no role. Because of the contact-free erosion process, die sinking EDM machines are durable and steady.


OSCAMRAX has been totally dedicated to design and manufacturing of electrical discharge machines and die sinker EDMs over many years. Our objective is to subvert the general impression of low machining speed of EDMs. Therefore, we have spent great efforts in developing high speed EDM machining technology, where to create the best results in speed, accuracy and surface roughness.


We offer the most comprehensive range of models including traditional type, CNC type and multiple 6 axes type in order to satisfy the market requirements precisely. If you need more information about EDM machines, welcome to visit our website and feel free to contact with OSCARMAX.

A Discussion on Hand Tree Saws, Pruners, and Other Arborist Equipment

As a dedicated arborist, you need to make sure you have the right tools to perform your job correctly, safely and utilizing your time. Of course, you want to keep the trees you are working in healthy and looking good. That means getting your hands on the best tree pruner, hand tree saw, and other arborist equipment. After all, the difference between doing a good job and a great job not only requires your skills but also your tool selection. Don’t let anyone tell you otherwise.


The Difference between Types of Tree Saws


When shopping for hand tree saws, you will come across various types of teeth and shapes of blade. These are not mere differences in aesthetics. Each has its own functional purpose. Here is a quick breakdown to guide you in selecting the right saw for your job:


  • Curved blade – Do you need a bit of control when cutting branches in tight areas? Do you need to cut quickly and speed up the job? Then this is the piece of arborist equipment for you.
  • Straight blade – A smoother cut at a slower pace than the curved blade. Hey you have to give a little to get a little right? Well, with the straight blade you also get the ultimate control.
  • Blades with gullets – Need something for bind free cutting? This is your ticket.
  • Fine teeth – Delicate cuts for smaller pieces of wood require smaller teeth. They will give you that beautiful, manicured look.
  • Large teeth – Obviously, these teeth come in handy when cutting larger branches. They work faster as you are not as concerned about making the cut perfect for the eye to see.


As you use your tree saw, keep in mind that you aren’t using a traditional hand saw. The term “saw” may imply that you move the piece of equipment back and forth to cut the wood. Not the case here whatsoever. Instead, make sure you use a downward stroke to cut the limb in one motion. Having trouble? Perhaps you need to replace your blade. They wear down faster than you might think making cutting more difficult.


Pruning Arborist Equipment


Poles, sheers, loppers-what are they and what are they for? Well, first of all you have the pole, which allows you to reach branches at various heights. Many arborist equipment suppliers allow you to build your own pole kit. That means you choose the head, base, and middle section to piece together for your required length. Most poles have interchangeable saw or pruner heads. Pruner poles come in wood, fiberglass landscape series, fiberglass professional series, fiberglass telescoping series and fiberglass dielectric series, which are poles that are foam filled for working around electricity. Silky Hayauchi poles extend to 21’ and come with saw blade only. The Silky Hayate extends to 20′ and is a saw blade only.


Sheers and loppers that are sold in arborist stores are of professional grade. They are for people who want an easier tool to use with continued performance year after year. Marvin brand shears and loppers are made from forged steel. These tools are not only great for the professional arborist and landscaper but general gardeners will appreciate their performance and lasting quality.


Remember, as a dedicated arborist, or even a power gardener, you need to make sure you have high quality arborist equipment.

Overview of Sawing Machines: Hack Saw, Band Saw, and Circular Saw

Sawing machines are primarily used to part material such as rough-cutting excess material away before machining or cutting curved patterns in sheetmetal. Sawing machines substitute mechanical or hydraulic powered motion for arm motion to achieve the speed necessary for production operations. The cutoff operation is usually one of the first requirements in any production process before any machining, welding, or forging is done. The saw blade has individual teeth that “track” through the workpiece, each tooth deepening the cut made by the preceding tooth in the direction of feed. The saw or work may be fed and by controlling the direction of feed, either straight or curved cuts can be made. The width of the cut (also known as “kerf”) is approximately equal to the thickness of the saw blade and because of this saw blades are made as thin as possible but with adequate tool strength and rigidity.


There are three common types of sawing machines, reciprocating or hack saw, band saw, and circular saw. These machines all perform the same operation but vary in capability, capacity, and application. Power hacksaws use a reciprocating stroke where on the cutting stroke the saw blade teeth are forced into the metal either by gravity or hydraulic pressure while on the return stroke the pressure is automatically removed to prolong saw blade life. Most of the machines come equipped with a chip tray and a cabinet base which contains the coolant reservoir and its circulating pump. Heavy duty power hacksaws come with automatic bar feeds where the stock is loaded on a carriage which automatically moves forward the necessary distance when the cutting is finished. Hydraulic pressure automatically operates the vise jaws, gauges the material, and raises and lowers the saw blade.


After being set up for cutting material to a specified length, the power hacksaw will operate automatically without need for an operator until all the material loaded on the carriage has been cut. Horizontal band saws are one of the most widely used sawing machines for cutoff operations. These band saws range from small manually operated machines to large, fully automatic production machines. Vertical band saws are also used but are primarily manually controlled machines used in tool rooms and shops for maintenance and low production work.


Band saws have several advantages over other kinds of cutoff machines. The saw blade cutting width or kerf is 1/16 in (0.16 cm) compared to 1/8 in (0.33 cm) for power hacksaws and abrasive disc circular saws, and 1/4 in (0.64 cm) for cold saws. This can represent a sizable savings especially when cutting large or expensive material. The thinner saw blades also require less power to cut through material making them more economical to operate. Because bandsaws have endless blades (band saw blades are welded together to create an endless loop) which cut continuously, the cutting rates are much higher.


Two of the most popular circular saws are the cold saw and the abrasive disc cutoff saw. Cold saws are low rpm circular saws for metal cutting. These saws range in size from hand-operated bench-top models with 8 in (20 cm) blades to fully automatic machines with blades of 3 in (7.6 cm) diameter and larger. Light duty manual or automatic machines are sometimes equipped with a swivel head which enables cuts to be made at different angles. These saws are mostly used for cutting structural shapes such as I-beams, angles, and channel sections because the circular blades can complete their cuts with less travel than straight blades. Heavy duty machines are available with bar feeds and can be used for cutting solid bars up to 10 in (25 cm). Material larger than this size would require excessively large blade diameters, which must be more than double the cutting capacity, which would become too costly along with the machine necessary to drive them. Different speed ranges are provided for cutting metals of different hardness and toughness, and built-in coolant systems help produce better finishes and prolong blade life.


Abrasive cutoff saws utilize an abrasive disc to separate material by using a grinding action. Abrasive cutoff saws are built for either manual operation or with power feeds, with either fixed or oscillating wheel heads. Oscillating wheel heads are used when cutting thick sections of tough materials such as titanium, nickel-based super-alloys, and other high alloy steels. Sizes range from small bench-top machines with 8 in (20 cm) wheels to bigger machines with 20 in (50 cm) or larger wheels. Abrasive cutoff saws are very useful for rapidly cutting small sizes of bar stock, tubing, and structural shapes and also for cutting tough or hardened materials that cannot be cut efficiently with other types of saws.

Comparisons between Variable and Fixed Displacement Hydraulic Pump

A hydraulic drive system uses a pressurized fluid to deliver force to distant machinery. Each system has several common components; the most universal is the hydraulic pump. The pump’s purpose is to pressurize the hydraulic fluid so that it will travel down the line and perform work on the other side. In an ‘open loop’ system, the fluid is drawn from a reserve tank, and deposited into the same tank after it has done its work. In a ‘closed loop’ system, the fluid is brought directly back to the hydraulic pump after passing through a hydraulic filter.


Fixed Displacement Hydraulic Pump

A fixed displacement hydraulic pump has a set flow rate — every stroke of the motor moves the same amount of fluid. Fixed displacement pumps are


  • Simple
  • Relatively inexpensive
  • Easier to maintain


The simplest type of fixed displacement pump is the gear pump, in which the hydraulic fluid is pushed by rotating gears. In some models, the gears are sequential; in the quieter and more efficient version, the gears are interlocking. Another common variation is the screw pump, which uses the classic Archimedes screw, which looks much like a drill bit, to move the fluid. They have the advantage of providing a high rate of flow at relatively low pressures.


Variable Displacement Hydraulic Pump

In a variable displacement pump, the flow rate and outlet pressure can be changed as the pump operates. This results in variable displacement hydraulic pumps that are


  • More complex
  • More expensive
  • Capable of doing a wider variety of jobs


The most common type of variable displacement pump is the rotary vane pump, which is a variation of the gear pump in which the ‘gear’ is offset and the ‘cogs’ aren’t fixed, but rather extend and retract as the gear turns, allowing the pump to increase the pressure of the fluid by compacting it as it pushes the fluid through. The top-tier pumps, however, are bent-axis piston-and-cylinder pumps, much like the ones that are used in an internal combustion engine.


Simple, fixed displacement hydraulic pumps are perfect for single jobs that need to be repeated indefinitely over long periods of time; variable displacement hydraulic pumps can be used to power a wider variety of tools, but require more expense and more attention.


Anson is the professional intra vane fixed displacement hydraulic pumps manufacturer in Taiwan. We provide various intra vane pump series, including IVP series, IVPQ series, IVPV series, and cartridge kits and so on hydraulic pumps. Welcome to send inquiries and feel free to contact Anson for more details about fixed displacement vane pumps and more hydraulics.

Advantages of Magnetic De-burring

Manufacturers of small, non-ferrous precision parts are often faced with the challenge of de-burring the part — the process of removing the raised edge or small piece of unwanted material that may remain attached to a part after a modification process. De-burring is especially important in the automotive, aerospace and electronics industries, where precision is critical and there is zero-tolerance for burr-ridden components.


Magnetic De-Burring

Burrs are traditionally removed manually, but this process is labor-intensive and time-consuming. A more convenient method is magnetic de-burring, which uses magnets and stainless steel media to polish and de-burr the parts without affecting the tolerances or inflicting damage.


The bottom of the deburring machine’s plastic container is first covered with stainless steel pins, and the parts to be de-burred along with the deburring solution are then added — the solution is a soap and water mixture, which helps to suspend the pins during the process.


Magnetic De-Burring Machine

The machine is then switched on. A magnetic disk in the machine below the container changes polarity constantly, agitating the pins in a whirlpool effect. This creates a ‘brushing’ action that polishes the parts and removes the burrs, but does not damage the part. Once the de-burring cycle is complete, the parts are separated from the pins through a strainer.


Advantages of Magnetic Burring

One of the greatest advantages of magnetic burring is the time saved on the deburring process, as it enables rapid deburring of the parts. In addition, the magnetic process allows for the simultaneous deburring and polishing of the parts, and since the media used are stainless steel pins, there is no residue left behind as in other deburring processes — secondary cleaning of the part is therefore not necessary. The tiny stainless steel pins used in the process can also reach areas of the part that other tumbling media (such as rocks) cannot, and magnetic action ensures that the pins do not become lodged in the part as rocks/stones sometimes do. Magnetic deburring also enables the deburring of areas such as blind, through- and cross-holes or threaded features that traditional deburring processes cannot accomplish.


Earth-Chain Enterprise Co., Ltd. is a professional manufacturer of magnetic tools. Magnetic de-burring machine and more magvise magnetic workholding etc. products all can be found on our website. If you need more information about magnetic de-burring, please feel free to contact with us or send inquiry to Earth-Chain.

LCD Video Wall Systems for Modern Control Rooms

The best display technologies of only 10 years ago are considered primitive by today’s standards. They were a poor return on investment because they were expensive and added little to the control room’s comparative ability to manage critical information. Expensive large format front and rear projectors were the primary choice. They were undependable, relatively low resolution, and required expensive maintenance contracts because they rarely had redundancy when a projection lamp failed. Then you add expensive, bulky hard-wire switchers to bring signals to the projectors and you still don’t have the capabilities of today’s most basic LCD video wall driven by a computerized controller. In fact, much of what was considered state of the art at the time was just “eye candy”; it looked good, but did little to advance the performance of the people using it.


What is considered a modern video wall system?

It employs a matrix of displays driven by a sophisticated computer that allows the operator to acquire and display more information faster than with older methods. This also means faster and better decision making. These are the type display systems that do much more than merely connect a switch between computers and individual displays mounted to the wall. These systems allow you to reach out on the data network and bring in an almost unlimited number of sources to the video wall, and as the network grows, it is unaffected except to say that more screen surface could be needed to display more information than before.


The growing popularity of LCD video wall systems

These are now more popular because they meet most performance requirements, require less investment and occupy the least amount of floor space. In fact they can be mounted on the wall taking up only 4-6″ in depth. These high resolution displays form a matrix or single pallet. Each display’s ultra-thin bezel is designed to minimize distraction when enlarging images across multiple displays.


These are relatively easy to install and require little maintenance or adjustment. They are rarely repaired because it’s easier and faster to replace than repair, however the typical industrial LCD display will run dependably for thousands of hours.


I should point out that these systems perform the same as video walls with other type displays because it’s the video wall controller, or brain of the system that acquires and displays what is shown on the video wall. The video controller (processor) doesn’t see the number of displays, or the type or size of displays. The controller sees the matrix of displays as a single display allowing the images to be easily placed and sized anywhere on the overall screen surface.


There are two types of LCD video wall used in control rooms; wall mounted or freestanding cabinet. Wall mounted systems require that the wall be reinforced and cannot be installed or easily relocated like a 12″ deep cabinet. The cabinet is modular and stores all supporting electronics in the base and as a result, can be easily expanded and relocated as requirements change.


For more information on this, please ask advice from an experienced LCD video wall solution provider like EAGO Vision, the company specializes in customizing LCDs monitors and troubleshooting electronic devices related issues.
