The Custom EPDM Molding Experts

Molded EPDM Rubber

EPDM molding is a durable and cost-effective solution ideal for outdoor and automotive applications due to its superior resistance to ozone, UV rays, and extreme temperatures. Whether produced via injection or compression methods, this synthetic rubber delivers excellent heat resistance, color stability, and a clean finish, serving as a reliable, high-performance alternative to neoprene.

EPDM Rubber Injection Molding

EPDM rubber injection molding is especially valued in the automotive and industrial sectors for its longevity and performance in harsh environments. EPDM also mimics the mechanical properties of both natural and synthetic rubber, while offering greater durability and lower cost compared to silicone.

Applications Best Suited For EPDM

However, EPDM is not suited for applications involving petroleum-based substances, solvents, or continuous exposure to aromatic hydrocarbons. It’s also not recommended for food contact or electrical insulation use.

With its versatility and resilience, EPDM remains a go-to material for roofing, HVAC, and a wide range of industrial applications—delivering long-lasting performance and reduced replacement costs.

FAQs About EPDM Rubber Molding

Yes, it is possible to injection mold EPDM. EPDM, or ethylene propylene diene monomer, is a synthetic rubber that works well with injection molding, as well as with other processes like compression and transfer molding.

The EPDM injection molding process involves heating the material and injecting it into a closed metal mold.

  1. First, a predetermined amount of EPDM is broken into smaller strips and fed into a screw.
  2. The material is heated and then injected under pressure into the mold cavity.
  3. As the mold fills, displaced air escapes through vents to prevent imperfections.
  4. The material is then cured under high pressure and elevated temperatures.
  5. Once the parts are fully cured, the mold opens and the parts are ejected, allowing for a new cycle to begin.
Here are a few of parts that are commonly made from EPDM injection molding:

  • Seals
  • Gaskets
  • Hoses
  • O-rings
  • Dampers
  • Bushings
