Our Plastic Injection Molding Services
At PMC, our plastic injection molding services are built around solving complex challenges with speed, precision, and confidence. Whether you need custom injection molding for intricate part geometries, overmolding for enhanced grip or aesthetics, or insert molding for added strength and electrical performance, we’ve got you covered.
Injection Molding
PMC’s custom plastic injection molding services are engineered for complex, high-precision applications. Our team thrives on tight tolerances, challenging geometries, and advanced engineered resins that other shops shy away from. Whether you’re producing aerospace, medical, or industrial components, we deliver consistent part quality backed by decades of molding expertise. Every part is made in the USA using a scientific, data-driven approach.
Overmolding
We specialize in multi-material overmolding that enhances product performance and aesthetics. Whether you need improved ergonomics, insulation, or chemical resistance, our overmolding capabilities offer lasting, integrated solutions. With our deep understanding of material compatibility and molding behavior, PMC can help you design and execute overmolded parts that perform in demanding environments.
Insert Molding
Insert molding combines metal components with molded plastics to reduce assembly steps and improve mechanical strength. PMC’s insert molding solutions are ideal for electronics, medical devices, and other high-performance products that require reinforced features or embedded components. By molding directly around bushings, terminals, or threaded inserts, we improve structural integrity while minimizing secondary operations.
Post-Molding Operations
Our value-added services go beyond the press. PMC offers a full suite of post-molding operations (including CNC machining, ultrasonic plastic welding, in-mold decoration, and assembly support) to help you bring finished products to market more efficiently. Every step is backed by the same rigorous quality control standards we apply to our molding processes.
Industries We Serve
PMC works with some of the most demanding industries in the world. From mission-critical aerospace and medical device components to rugged filtration housings and durable electronic enclosures, our engineered resin expertise helps ensure every product performs under pressure.
We understand the regulatory, technical, and environmental challenges your industry faces and we build solutions that meet them. With decades of cross-sector experience, we bring insight and innovation to every project.
