Plastic Materials of CNC Prototype
In the CNC prototype industry, the CNC prototypes are made by plastic materials including
general materials ABS, PC, PMMA and PA. POM. The characteristic of several general
plastic materials are introduced as the following.
ABS: ABS is a kind of new material in CNC prototype industry, whose name is acrylonitrile,
butadiene styrenics copolymers, which is the maximum production and the most common used
polymer. It unify the properties of PS,SAN,BS, which is of the good mechanical property of
tough, hard and firm. Its main characteristic includes excellent impact strength, good stability
of size, dyeability, good molding processing and machining, good mechanical strength, high-stiffness,
low moisture uptake, good corrosion resistance, simple connection, avirulent insipidity, excellent
chemical properties and electrical insulation performance. In the high temperature, ABS endure
and isn’t out of shape, in the low temperature, it is of high impact toughness. It is also a tough ,
not easy to be scratched material.
PC: The major components of PC is polycarbonate, which is a high quality material made
by CO-EXTRUSION. Its surface covers absorbent of high concentrations of ultraviolet
with long resistance and fast colour.
PMMA: Its English name is acrylic, whose chemical name is polymethylmethacrylate.
It is an important thermoplastic plastic, which is of good transparency, chemical stability
and weather resistance. It is also easy to paint, to process.
