Full-Scope Manufacturing Capabilities

APMC is a plastic injection molding company that covers every stage of your program, so your team isn’t stitching together vendors to ship one part. As a custom plastic manufacturer, we offer:

Plastic Injection Molding

Precision custom plastic parts across a wide range of resins, tolerances, and production volumes, built for demanding OEM programs.

Tooling & Mold Making

New molds, tool transfers, moldflow analysis, and 500,000-shot guarantees on standard resin types back every tooling program.

Assembly & Kitting

From simple two-component assemblies to full turnkey finished goods with packaging, kitting runs to full truckload quantities when programs demand it.

Overmolding

Metal components encapsulated in precision plastic, creating durable, integrated parts for complex applications where material consolidation adds measurable value.

Insert Molding

Pins, bushings, washers, and other metal inserts placed directly into the mold and permanently bonded in a single production operation.

Rubber Gaskets & Seals

Sourced through our manufacturing partnership, rubber gaskets and seals are available when they are part of a broader program we are running.

Supply Chain Management

Raw material and finished goods inventory, VMI programs, Kanban fulfillment, and direct EDI connectivity keep your programs moving without disruption.

Our Proven Process

Every APMC program follows a disciplined path. The same process that qualifies a power generation component gets a transferred tool back into stable production. Consistent execution, transparent communication, and data-driven accountability at every step.
