Overmolded Assembly for Performance Equipment
A multi-material component required rigid structural integrity combined with a durable elastomer grip surface. Early prototypes experienced inconsistent bonding and cosmetic imperfections, creating performance concerns ahead of production release.
A manufacturer of industrial equipment required a high-precision molded component integrated into a mechanical assembly where dimensional variation directly impacted performance. Previous production runs from another supplier resulted in inconsistent tolerances and assembly friction.
Client Confidential – Industrial Equipment Manufacturer
A product engineering team required a tight-tolerance injection molded component integrated into a larger mechanical assembly. Previous suppliers introduced dimensional variability, creating downstream assembly friction and inconsistent performance across batches.
Paradigm Plastics approached the project with structured DFM analysis, controlled tooling refinement, and documented process parameter validation prior to production release. The focus was not speed — it was repeatability.
