MoldWorksEngineered Elastomers.
Production-Ready Partnership.
Compression, injection, and liquid silicone molding from prototype to 100K+ annual run. Tolerances measured in thousandths of an inch.
Three Processes.
One Production Partner.
From first-article inspection to full-rate production, our press bay runs three-shift operations with SPC monitoring at every cavity.
High-Volume Gaskets & Seals
Uncured rubber compounds loaded into open-cavity tooling under 250–850-ton hydraulic press. Ideal for flat gaskets, diaphragms, and complex cross-section seals where flash control is critical.
O-rings, flat gaskets, HNBR transmission seals
Precision Overmolding & Inserts
Pre-plasticized compound injected under pressure into closed multi-cavity tooling. Eliminates pre-form variability, tightens dimensional control, and enables metal insert overmolding for connector bodies and grommets.
Overmolded connectors, grommets, vibration isolators
FDA-Grade Keypads & Membranes
Two-component platinum-catalyzed silicone metered, mixed, and injected cold into heated tooling. Flash-free parts with biocompatible certification for medical devices, infant products, and implantable-adjacent applications.
Silicone keypads, medical membranes, infant nipples
Every process includes first-article inspection, PPAP documentation, and dimensional reporting per AIAG standards.
