Molded Cable Assembly
Custom overmolded cable assemblies with integrated strain relief, IP-rated sealing, and ruggedized connectors for harsh robotic environments.
Overview
Our molded cable assemblies combine precision injection-molded or insert-molded thermoplastic encapsulation with high-flex robotic-grade conductors. Each assembly receives a factory-applied overmold at the cable-to-connector junction — eliminating the weakest failure point in conventional crimped or potted designs. The result: a monolithic, sealed interface that resists pull-out forces exceeding 200 N, blocks moisture and particulate ingress to IP67/IP68 levels, and survives millions of flex cycles without conductor fatigue at the termination point. We mold with TPU, PVC, TPE, and silicone compounds matched to your operating temperature range, chemical exposure profile, and required flex life. From single-cavity prototype tooling to multi-cavity production molds producing 50,000+ assemblies per month, our in-house molding cells run 24/7 under IPC/WHMA-A-620 Class 3 workmanship standards.

Scenario
A US energy management company needed initial physical samples to validate a complex custom overmolded power cable design before committing to production tooling.
Challenge
Standard production molds for overmolded cable assemblies are costly and time-consuming, creating a barrier for early-stage NPI validation requiring only a handful of units.
What we did
Proposed a rapid prototyping approach using silicone molds instead of hard tooling, allocating 50 pieces of raw material to produce an initial batch of 5 sample units for testing.
Outcome
Delivered functional samples within a 3-4 week turnaround (including 2 weeks for silicone mold creation), enabling the customer to proceed with physical testing and design iteration without upfront hard tooling investment.
Concrete numbers
- 5 sample units produced
- 50 pieces raw material allocated
- 2 weeks silicone mold creation
- 3-4 weeks total sample turnaround

What You Get Back
Buyer Questions Before RFQ
What should we send to get an accurate quote?
Send your drawing, BOM, quantity forecast, application environment, and any required approvals. Missing inputs create avoidable assumptions in pricing and lead time.
Will your team review the design before production?
Yes. Engineering review happens before quotation so connector, flex-life, shielding, and routing risks are flagged before you commit.
Can you support prototype through volume release?
Yes. We support first samples, validation builds, and production ramp with traceability and test requirements kept aligned.
