ABS Prototypes
Acrylonitrile Butadiene Styrene (ABS) is a popular thermoplastic polymer widely used in plastic prototype manufacturing due to its excellent impact resistance and machinability. This engineering plastic maintains good dimensional stability and can be easily processed using both CNC machining and 3D printing technologies. ABS prototypes are ideal for functional testing, automotive components, and consumer electronics enclosures.
Polyoxymethylene (POM), commonly known as Acetal, is a high-precision engineering plastic offering exceptional dimensional stability and low friction coefficient. Its excellent wear resistance makes it perfect for manufacturing prototypes of gears, bearings, and other mechanical components. POM prototypes maintain tight tolerances (±0.05mm) and perform well in moist environments.
