ABS: acrylonitrile butadien styrene, is widely used in applicants and industries. It has superior toughness and strength, resisting against impact, temperature. This kind of materials are also easily be molded and colorfast.

Celcon ( Acetal ): also be known as polyoxymethylene (PDM), polyacetal or polyformaldehyde. This kind of material has outstanding toughness, excellent wear, creep resistance. It can against chemical solvent and easily to colorize. It be good at heat distortion, and has low moisture absorption.

Polypropylene: with chemical resistance, elasticity and toughness, fatigue resistance, this kind of material is the widest using in plastic injection molding. It is used in packaging, bottle caps or somethings like these.

Hips ( High-impact Polystyrehe ): it is widely used in printing applicants. It has good impact resistance, can be easily dealt by machine like cutting, has fine dimensional stability, outstanding aesthetic qualities, highly customizable surface.

LDPE: low-density polyethylene is a flexible type of plyethylene. It has superior moisture resistance, high-impact strength, good chemical resistance, and translucence, weatherproof. It can be easily processed with most methods.

There are some operating principle of injection plastic molds.

Automatic production process. Powered by electric, injection mold works automatically. From injecting materials to push parts leave away from parts cavities, the process of mold producing is totally automatic.

With the feature of injection molding that it has expensive change cost, a right product design at first is necessary for your injection mold making. Thus production design is other things you should consider when you make injection molding.
