Plastic Injection Molding Services

Injection molding forces molten thermoplastic into a precision steel or aluminum mold, producing identical parts at high repeatability and low piece-price once tooling is in place. We manage the entire program: design-for-molding review, mold design and build, sampling and first-article approval, and validated production, so you deal with a single accountable supplier.

Design-for-manufacturability is critical to good molded parts. Our engineering review addresses uniform wall thickness, draft, rib and boss proportions, gate location, and shrink compensation before steel is cut — decisions that determine part quality, cycle time, and cost. We tune process parameters and verify dimensions against the print under our ISO 9001:2015 system.

We mold commodity resins such as ABS, polypropylene, and polycarbonate as well as engineering-grade materials including nylon, PEEK, acetal, and glass-filled compounds, with options for colorants, flame-retardant grades, and inserts. Insert molding and over-molding are available for parts that combine plastic with metal components.

Molded parts frequently integrate with our machining, stamping, and kitting operations, letting Esco deliver finished assemblies rather than loose components. Tooling can be built for prototype bridge production or full multi-cavity high-volume manufacturing depending on your program.
