Overmolding Services
One molded part can replace an assembly you’re currently building by hand. Get in touch with American Plastic Molding today.
Our Overmolding Services Build the Assembly Into the Part
When a metal component and its plastic housing arrive as two pieces, someone has to join them, and that step invites cost, delay, and failure points. American Plastic Molding’s overmolding services remove it. We place your metal part directly into the mold and shoot plastic around it, so the finished component comes off the press already integrated, sealed, and ready for the next operation. As an overmolding company that also molds, tools, and assembles together, we engineer the bond, the resin, and the process together. The result is a stronger part, fewer pieces to track, and one supplier responsible for all of it.
Metal Overmolding Engineered for a Permanent Bond
Metal overmolding is where our overmolding services do their heaviest work. Pins, brackets, and valves get positioned in the tool, then encapsulated so the plastic becomes structurally integral to the metal rather than merely attached. APMC tunes gate location, resin selection, and fill so thin walls don’t short-shot and inserts don’t shift. Electronics and other substrates can be evaluated the same way, and every program is validated before production so what launches stays repeatable instead of becoming a one-off experiment on your timeline.
Ship a Finished Part, Not a Bag of Components
Bring American Plastic Molding your metal insert and your goal, and we’ll show you how our overmolding services can consolidate it into one durable piece.
Overmolding Built Around Where the Part Has to Perform
Different industries push overmolded parts in different directions, and American Plastic Molding matches resin, insert, and process to the conditions each component faces in service.
Industrial Components Under Constant Load
Industrial programs lean on bracket overmolding and reinforced inserts for parts that take daily abuse. APMC’s overmolding process locks metal into plastic so mounting points and housings survive real duty cycles.
Defense Hardware That Can't Come Apart
As an overmolding manufacturer supporting ITAR-registered work, APMC encapsulates connector housings, brackets, and protective components where a loosened insert in the field is simply not an option.
Power and Energy Parts Built to Seal
For power and energy hardware, APMC’s overmolding services seal connectors and enclosure components against moisture and dust. UV-stable, harsh-environment resins hold up to outdoor and high-heat exposure over long service lives.
Commercial Vehicle Parts That Take the Road
Semi-trailer and heavy-truck components face vibration, impact, and weather. APMC overmolds metal-to-plastic assemblies engineered to stay intact through the pounding that on-highway service delivers mile after mile.
