Injection molding is utilized for all thermoplastics. Material for the part is fed into a heated barrel, mixed, and forced into a mold cavity, where it cools and hardens to the configuration of the cavity.
Mold design = careful deliberation
Parts to be injection molded are carefully designed to facilitate the molding process. Material used for the part, the desired shape and features of the part, the material of the mold, and the properties of the molding machine must all be taken into account before the mold is designed.
Molds are made by local mold-builders after a product is designed. Cavities and cores are precision machined into the desired metal base.
Advances in 3D printing technology and materials offers the ability to produce cavities, and cores, for temporary molds used in low-production injection molding.
APS molding machines ranging from 67 ton 3.6 ounce up to 360 tons 29.8 ounce.
Our machines are state of the art. Machines use PLC's (Programmable Logic Controllers) and hydraulic feedback sensors which govern very tight control of the process. Close tolerances and quick cycle times are the hallmarks at APS.
