Plastic injection molding produces plastic parts by forcing molten plastic into a mold where it cools and hardens. In plastic injection molding granular plastic is fed by gravity from a hopper into a heated barrel. As the granules are moved forward by a screw-type plunger, the plastic is forced into a heating chamber, where it [...]

Plastic injection molding is the primary process for manufacturing plastic parts. Plastic is well known to be a very versatile and economical material that has been used in many applications. Although the tooling to produce it is quite expensive, the final cost can be very low. Complex geometries are possible and limited only to mold [...]
