The Full Scope of Custom Manufacturing Services
One partner for custom manufacturing services, APMC handles everything from first shot to final shipment.
APMC is the Ultimate Manufacturer for All Your Needs
American Plastic Molding combines engineering, tooling, molding, and assembly under one roof, giving OEM and Tier teams a single accountable source for complex programs and tight launches.
In-House Capabilities: Every program runs through our in-house engineering team first, so design-for-manufacturability input and moldflow analysis catch problems before a part reaches the press.
Employee-Owned: Because we are 100% employee-owned, the people running your tools and solving your launch issues hold a personal stake in the outcome, not just a paycheck.
One-Stop Services: Our one-stop model keeps molding, secondary operations, and assembly under one roof, replacing a web of vendors with one team answerable for the entire build.
Our Services That Cover the Full Build
From plastic manufacturing solutions to turnkey supply chain support, APMC handles each stage internally so nothing gets lost in a handoff between suppliers.
Plastic Injection Molding
APMC molds precision plastic parts on presses sized for everything from tight-tolerance components to large housings, backed by scientific process control and full PPAP documentation.
Tooling & Mold Making
New tool builds, transfers, and mold repairs all happen in-house, so your tooling stays in stable production instead of shuttling between separate outside shops.
Assembly & Kitting
From two-component sub-assemblies to full turnkey finished goods with packaging, APMC assembles and kits to truckload quantities, with vision-system and statistical-sampling inspection built in throughout.
Overmolding
APMC bonds resin over metal inserts and substrates to combine parts, add grip, and seal components, for equipment like metal pins, brackets, and valves.
Insert Molding
Threaded inserts, terminals, and metal features get molded directly into the plastic, producing a single strong part and eliminating downstream press-fit or fastening operations.
Rubber Gaskets & Seals
Through a manufacturing partnership, APMC supplies custom rubber gaskets, seals, and O-rings alongside your molded parts, keeping related sealing components on a single purchase order.
Supply Chain Management
VMI programs, Kanban fulfillment, and direct EDI connectivity keep your line stocked, with over a million dollars of resin held on-site to protect your schedules.

Proof From the Programs We Run
Buyers in power and energy, medical devices, and industrial programs don’t hand critical work to an unproven supplier. Our success stories show how American Plastic Molding solved the problems that mattered: reworking an over-engineered resin to cut cost while holding UL compliance for an energy OEM, building an AI-driven inspection cell that drove escaped defects to near zero for an equipment manufacturer, and dialing in a narrow-processing resin for a harsh-environment part that had beaten other molders.
From commercial vehicle components to consumer appliance housings and defense-grade work, these case studies show what one partner delivers. Read the results behind the claims.
