Common Questions

Overmolded Harness FAQ

What IP ratings can you achieve with overmolding?

Our overmolded solutions can be engineered to meet IP67 (protection against temporary immersion) or IP68 (protection against continuous immersion) ratings, depending on connector design and material selection. We work closely with you to determine the optimal rating for your application environment.

What materials are available for overmolding?

We offer various overmold materials including PVC, TPE/TPU, nylon, silicone, and EPDM. Material selection depends on environmental conditions, flexibility requirements, chemical exposure, and temperature range. We can recommend the best material for your application.

What is the minimum order quantity for overmolded harnesses?

Leveraging our in-house tooling and flexible manufacturing, we efficiently support low-volume production of overmolded harnesses. For new designs, tooling costs are required upfront but are amortized across the production run. Please contact us to discuss your project-specific requirements.

Can you match specific colors for overmolds?

Yes, we can color-match overmolds to your specifications including Pantone colors. Custom colors are available for production quantities. We can also mold in logos, part numbers, and other identification features.
