How To Properly Pick Your Precision Plastic?
Precision plastic is a choice of many manufacturers of components and parts, because of properties that are unique to this material. Heat tolerance,
hardness, resiliency, machinability and dimensional stability make plastic a very versatile material.
For diverse range of end-product applications, plastic becomes a bankable commodity. But, not all plastic types are fit for plastic machining. Plastics
that are soft are no good because they cannot be cut into precise standards. They have the tendency to bend or deform while going through cutting
Rigid plastics are a better alternative as fine dimensional tolerances are easily achieved. Nylon, with its very good physical properties makes a good
precision plastic. It belongs to a semi-crystalline group, and has an impressive resistance in heat, chemical, and wear.
Moreover, it is fair and easy in processing. Some of its applications include electrical connectors, sports and recreational equipment, fabric, carpeting,
sportswear and automotive oil pans.
Nylon plastic is also used to manufacture fishing lines, brush bristles, fluid reservoirs, cable ties and film packaging. Even gears, slides, cams and
bearings are available in nylon. Like nylon, PTFE is a semi-crystalline plastic. It shows a distinct combination of heat resistance and low friction with
chemical and good electrical properties. There is no moisture absorption with PTFE and has high arch resistance.
Bronze filled PTFE, its complete name, is capable of lubricating itself with a low coefficient of friction. It is ideal for structural and bearing and wear
applications, as it can withstand moderate to high temperatures.
Most semi-crystalline materials have less vulnerability to cracking, and chipping like other plastic materials. PEEK is also a precision plastic with its
highest elongation capacity. Its toughness makes it perfect for instrument components in which aesthetics are significant.
Also, seal components in which inertness and ductility are signi
