So you need a custom plastic part or product, but you don’t know how to get it made.
Is it large or small? Should it be flexible or stiff? Is it round, square, or some weird shape? Do you already have a mold, or do you need to have one made?
This guide will explain the different kinds of molding processes available today to help you discover the ideal process for your product.]]>
Introduction：In general, the accuracy of PTFE product is not easy to control because its coefficient of linear expansion is higher than that of metals, and its one of volume transition temperature is around room temperature causes volume changes approximately 1 to 2%. Moreover, thin-walled PTFE products are known to be difficult to machining because not only PTFE is flexible and elastic material, but also residual stress remains after molding sometimes deform due to frictional heat generated during the machining process or due to aging after machining. Such deformation could influence dimensional accuracy.]]>
Ultra High Molecular Weight Polyethylene, or UHMW, is a thermoplastic with a high abrasion resistance and excellent waterproof capabilities that make it a favorite material in several industries. Available in sheet, rod and tube formats, as well as a variety of profiles, to fit many needs. This tough, durable material also works well in applications where a low coefficient of friction is needed, making it quite versatile. Here are some of the top applications where UHMW is commonly found.]]>
Tensile structures have been used for millennia. When indigenous peoples required shelter that was lightweight and structurally sound, fabrics made from animal hides and easily transportable elements were the most viable solution. At the Roman Colosseum, a retractable Velarium provided shading for a more comfortable spectator experience. Now, ethylene tetrafluoroethylene (ETFE) is offering new opportunities.
A relatively new product within the industry, ETFE is a fluorine-based plastic that remains strong across a wide range of temperatures and is highly resistive to corrosion. It was developed from polytetrafluoro-ethylene (PTFE)—also known as Teflon—a strong, lightweight, fire-retardant fabric membrane that was originally formulated for space exploration apparel, but later used for architectural applications and transparent envelopes.]]>
Extrusion is a process of manufacturing long products of constant cross-section (rods, sheets, pipes, films, wire insulation coating) forcing soften polymer through a die with an opening.]]>
Now you can live, work or play with less worry about your clothes, home fashions and the planet. New ptfe fabric protector Shield and Clean Portfolio is advanced care for a better planet.]]>
Steel-lined PTFE equipment usually has a discharge port, a mirror, etc. in the production, but how to successfully apply this type of nozzle to the complicated head intersection line, of course, our answer is welding So how do you weld it? How to control the temperature of PTFE welding? Let us tell you one by one.]]>

What are PTFE and PFOA? Where are they found?]]>
The base material was made via fiberglass impregnation in PTFE and refined, coating with silicone adhesive and with excellent heat resistant and mechanical strength.
Good release and smooth
Good performance of high temperature keeping, stable size.
Small friction coefficient, good insulation.
Good corrosion resistance.
High speed rotary shaft seals are found in many applications. Examples would include cryogenic deflashing equipment, vacuum pumps, torpedo shaft seals, gas turbine engine starters, and submersible dredge pumps. AC/DC motors often require high speed shaft seals, and can be found in items like CNC tool spindles and dental or surgical instruments.
