Plastic Molding Capabilities
Our basic guidelines for plastic injection molding include important design considerations to help improve part moldability, enhance cosmetic appearance, and reduce overall production time.
| US | Metric | |
| SIZE | 18.9 in. x 29.6 in. x 8 in. | 480mm x 751mm x 203mm |
| VOLUME | 59 cu. in. | 966,837 cu. mm |
| DEPTH | 4 in. from parting line | 101mm from parting line |
| Up to 8 in. if parting line can pass through the middle of the part | Up to 203.2mm if the parting line can pass through the middle of the part | |

What is Plastic Injection Molding?
Injection molding is a manufacturing process that involves filling a metal mold cavity with liquid plastic resin, which cools and solidifies into a plastic part.
This method is commonly used for high-volume production due to its low material waste and cost per part. It’s ideal for industries such as medical devices, consumer products, and automotive.
Our plastic injection molding process produces custom prototypes and end-use production parts with lead times as fast as one day. We utilize aluminum molds for cost-efficient tooling and accelerated manufacturing cycles, and we stock around 200 different thermoplastic resins.
