Custom Cable Overmolding
Enhance durability, waterproofing, and aesthetics with our Low Pressure Molding (LPM) technology. The superior alternative to heat shrink and standard shells.
Why Choose Overmolding?
Standard connectors often fail at the strain relief point. Overmolding creates a permanent, watertight chemical bond between the cable and the connector.
Waterproof Sealing (IP67+)
Completely encapsulates soldering points, preventing moisture and dust ingress.
Superior Strain Relief
Absorbs bending forces, preventing wire breakage at the termination point. Essential for robotics.
Custom Branding
Add your company logo directly onto the connector mold. Available in any color or shape.
Our Overmolding Process
From 3D mold design to mass production in 4 steps.
Live: Low Pressure Molding (LPM) Machine in Action
3D Design
We design the mold tool based on your connector and cable diameter.
Tooling
Fast in-house tooling production. (Lead time: 7-10 days).
Injection
Using PVC, TPU, or TPE materials with Low Pressure Molding machines.
Testing
Dimensional check, waterproof test, and visual inspection.
IP67/IP68 Waterproof Verification
Molding is just the first step. We verify the seal integrity of every waterproof connector using advanced air-leakage testing (vacuum decay method).
-
Non-Destructive Testing:
Using compressed air to detect microscopic leaks without damaging the cable.
-
Custom Fixtures:
Dedicated tooling designed for each connector type to ensure precise sealing.
