Background

A US energy management company needed initial physical samples to validate a complex custom overmolded power cable design before committing to production tooling.

The Challenge

Standard production molds for overmolded cable assemblies are costly and slow to build, creating a barrier for early-stage NPI validation that needed only a handful of units.

Our Solution

We proposed a rapid prototyping approach using silicone molds instead of hard tooling. We allocated 50 pieces of raw material to produce an initial batch of 5 sample units for testing.

The Result

Functional samples were delivered within a 3-4 week turnaround, including 2 weeks for silicone mold creation. The customer proceeded with physical testing and design iteration without any upfront hard-tooling investment.
