Custom Injection Molding and Molded Components, Made in the USA

DEM Manufacturing is a 100% U.S.-based molded components manufacturer producing plastic injection molding components to demanding specifications. All molding happens domestically in our Ohio facility, within ISO 9001:2015 and ISO 13485:2016 quality systems, so sourcing, tooling, and traceability stay inside one compliant, American chain of custody, an advantage for defense and medical programs alike.

Injection molding has been core to DEM since our founding in 1993. By managing tooling design, maintenance, and modifications entirely in-house, we hold quality, durability, and on-time delivery steady without outsourcing. Our injection molding services handle jobs of any size, from small runs to large-scale production, all built to your exact requirements.

  • Nine injection molding machines for flexible capacity
  • Tooling from simple two-part molds to complex multi-cavity designs
  • Stock of recycled and virgin resins to match project requirements
  • Support for overmolded plastic components within the same quality system

What Sets DEM's Injection Molding Apart?

No job is too big or small.

In-House Engineering

Our engineers minimize downtime and protect on-time delivery because design, tooling, and molding all happen under one roof.

Precision and Flexibility

Precision injection molding supports any volume, size, or complexity, with one-time delivery or scheduled stocking for ongoing production needs.

Overmolding Capability

We mold overmolded plastic over electronics and connectors for protection and durability, combining molding with assembly under one system.

Injection Molded Component Materials

Our broad range of resins allows for materials tailored to your project’s performance requirements. This ensures components meet various technical requirements, from strength and durability to specialized functions like conductivity.

We Stock a Variety of Recycled and Virgin Resins, Including:

  • ABS
  • Acrylics
  • Glass-filled nylons
  • Metal-filled ABS (conductive resin)
  • Nylons
  • Polycarbonates
  • Polypropylenes
  • PVC
  • Santoprene
  • Others available on a project-by-project basis

Enclosures and Housings for Electronic Products

Many products depend on protective housings that must meet tight tolerances and material requirements. DEM's electronic enclosure manufacturing produces durable, precise enclosures within the same quality system that governs the electronics inside them. That integration is a real advantage for electronics enclosure molding, since one team is accountable for how the housing and the electronic assembly fit and function together.
 
Our broad range of resins lets us match materials to your project's performance requirements, from strength and durability to conductivity. We stock ABS, acrylics, glass-filled nylons, metal-filled conductive ABS, nylons, polycarbonates, polypropylenes, PVC, and Santoprene, with others available per project. As your partner for molded plastic parts, DEM delivers manufacturing that keeps you ahead of your production schedule. Talk to an expert about your molding challenge.

FAQs

1. What types of injection molded plastic components do you manufacture?

DEM manufactures durable, high-performance injection molded plastic components designed for defense, medical, and industrial use. Our in-house capabilities allow for precise, repeatable production of both standalone parts and overmolded electronics.

2. How do you optimize injection mold components for quality and speed?

We design and build injection mold components with scalable tooling that balances investment and annual volume. DEM’s experienced engineers create modular tools and use rapid prototyping to accelerate time to market without compromising performance.

3. Can you produce injection molded parts with electronics overmolded inside them?

Yes. We produce injection molded parts and overmolded electronics within the same quality system, molding material over circuitry and connectors for protection and durability, so housings and electronics are built together rather than separately.

4. What resins can you use for plastic injection molding, including conductive options?

Our plastic injection molding uses recycled and virgin resins including ABS, acrylics, glass-filled nylons, metal-filled conductive ABS, nylons, polycarbonates, polypropylenes, PVC, and Santoprene, with other materials sourced per project requirements.

5. How do you keep precision injection molding consistent across a large production run?

Our precision injection molding stays consistent because we manage tooling design, maintenance, and modifications in-house on nine machines, with structured quality inspection that holds tolerances steady from the first part to the last.

6. Does DEM build its own injection mold tooling?

Yes. DEM designs and fabricates tooling in-house, from aluminum and 3D-printed molds for prototypes and short runs to durable stainless steel molds for high-volume production, which protects quality and lead times.

7. Can DEM make plastic enclosures for electronic products?

Yes. DEM produces electronic enclosures and housings within the same quality system that governs the electronics inside them, so one team is accountable for how the housing and assembly fit and function together.

8. Is DEM's injection molding done domestically?

Yes. All molding happens in our Ohio facility within ISO 9001 and ISO 13485 quality systems, keeping sourcing, tooling, and traceability inside one compliant, U.S.-based chain of custody.

9. What size molding jobs can DEM handle?

DEM handles jobs of any size on nine injection molding machines, from small prototype runs to large-scale production, with tooling ranging from simple two-part molds to complex multi-cavity designs.
