Plastic Injection Molding Services Across the USA

A plastic component may start as a carefully engineered design, but its real test comes when you need to produce it accurately from one run to the next. Reaching that point demands a manufacturer who knows what the part needs to do and then determines how its design will translate into production.

Here at Design Plastics, we provide custom injection molding solutions for companies across the USA, with the capabilities to accommodate your project. From its early prototype through small- or high-volume runs, our team will help you refine the part, develop the mold, and establish a production approach around its performance and manufacturing requirements.

The injection molding of plastics uses heat and pressure to introduce molten thermoplastic into a closed mold. The material fills the mold cavity, cools into the intended form, and releases as a finished part. Because the same mold produces each component, companies can maintain the dimensions, features, and overall consistency their products need across a production run. The mold itself can incorporate detailed geometry that would otherwise require additional manufacturing or assembly steps.

Our presses range from 55 tons up to 730 tons, allowing our team to accommodate different part sizes and injection molding production requirements. We work with thermoplastics such as POM, PVC, TPV, TPO and many more, selecting materials based on the strength, flexibility, and durability the finished component needs.

Our in-house engineering and tooling capabilities keep part design, mold development, and manufacturing all under one roof. This direct involvement helps us identify any necessary adjustments that need to be made before your component enters a larger production run.

Our team will first review your component’s geometry, material requirements, intended function, and expected production volume. We’ll then make suggestions on design improvements for manufacturability. Before proceeding with the full production run, our team will evaluate the molded parts against the approved design.

Manufacturers across aerospace, automotive, agriculture, medical, retail, government, and industrial markets use molded plastic components in products and equipment with very different operating requirements.

Design Plastics also serves companies developing recreational vehicles and outdoor tools, where a component’s weight, strength, fit, and exposure conditions can influence its design. Our injection plastic molding capabilities give OEMs a way to create purpose-built parts around the equipment they manufacture and the conditions those parts will inevitably encounter.
