Overmolding: quick facts

Materials: TPE, polyurethane and epoxy.
Used on: Cables, connectors and PCBAs.
Built in: Reinforcement, environmental sealing and strain relief.
Support: Custom mold design.
Process: Low-pressure overmolding. Low-viscosity material is injected at low pressure, so sensitive parts are not damaged.
Volume: Small volume, high mix. Low tooling cost suits prototypes and short runs.
Industries: Automotive, medical devices, industrial automation and safety equipment.
Standards we hold: ISO 9001, ISO 13485 and IPC-A-610.
Why overmold

What overmolding gives your product

  • Moisture barrier: keeps water and contaminants out.
  • Shock and vibration resistance: built for rugged use.
  • Heat conduction: helps keep parts cooler.
  • Simpler BOM: no lids or fasteners.
  • Smaller package: room for a more compact design.
  • Strain relief: protects cable and connector joints.

Overmolding, potting or conformal coating

Potting and conformal coating also protect electronics. Potting often adds bulk and cure time. Coating protects the surface but adds no strain relief. Overmolding protects the part and adds shape and strength in one step.

We help you choose the right method for your product. We also run conformal coating in-house.

The process

How an overmolding job runs

  1. We review your design. We look at the environment it must survive.
  2. We design the mold with you.
  3. We overmold the cable, connector or PCBA.
  4. We inspect and test the finished part.
