CChurub Rubber™

Manufacturing Capabilities

One factory, four silicone processes, and a toolroom that answers to part designers — not a subcontractor.

LSR Liquid Injection Molding (LIM)

Best for precision, high-volume and medical parts. Flash-free, ±0.05 mm capable, 30–90s cycles, overmolding in one shot.

Compression & Transfer Molding

Cost-effective for lower volumes and large cross-sections; widest compound compatibility including specialty elastomers.

Overmolding & Insert Molding

Chemically bonded silicone-to-metal and silicone-to-plastic assemblies with plasma primer-free options for food contact.

Extrusion & Cold-Shrink

Silicone tubing, strips and cold-shrink cable accessories for telecom and power applications.
