Custom Plastic Injection Molding in the Midwest & Beyond

From our Scottsburg headquarters, American Plastic Molding delivers custom plastic injection molding in the Midwest while serving OEMs well beyond the region.

One Accountable Partner Across the Region and Beyond

APMC built its reputation on custom plastic injection molding in the Midwest, but the reach goes further than the map suggests. From Scottsburg, Indiana, we bring molding, tooling, assembly, and supply chain support together under one roof, so a sourcing engineer trades a scattered vendor list for one accountable, employee-owned partner. Most regional plants sit within a six-hour drive, which keeps freight affordable and same-day service realistic. When a program grows past state lines, American Plastic Molding ships across the U.S. and internationally without missing a step, so your supplier never becomes the reason growth stalls.

Everything Your Program Needs, Handled In-House

Because American Plastic Molding runs custom plastic injection molding in the Midwest alongside every value-added service below, you consolidate a full program with one team instead of managing several.

Plastic Injection Molding

Presses up to 900 tons cover everything from tight-tolerance prototypes to high-cavity production, so a single molder scales with your program instead of capping it.

Tooling & Mold Making

Our in-house toolroom builds new molds and rescues tools stuck at failing suppliers, transferring and requalifying them until output stabilizes.

Assembly & Kitting

Sub-assemblies, kitting to full truckloads, and packaged finished goods leave our floor line-ready, removing the separate assembly houses that slow programs down.

Overmolding

Bonding a soft layer over a rigid core in one operation yields sealed, ergonomic parts and strikes downstream assembly steps from your bill of materials.

Insert Molding

Molding resin around threaded inserts and metal contacts produces rugged, integrated parts and drops loose hardware and post-mold labor from the build.

Rubber Gaskets & Seals

Through our manufacturing partnership, sealing components ship on the same order as your molded parts, keeping sourcing simple.

Supply Chain Management

VMI, Kanban, and EDI programs hold inventory ready and keep resin stocked, protecting your line from shortages and late deliveries.
