Compression Molds
Multi-cavity compression molds for O-rings, gaskets and bonded parts — economical at any volume.
Application Overview
Compression molding remains the most economical route for solid silicone, especially for large parts and mid-volume O-rings. We build multi-cavity compression molds (up to 200+ cavities for standard O-ring sizes) with balanced filling, quick-change insert systems and vacuum options for critical cosmetic parts.
Technical Standards
- ✓Cavity steel S136 / 1.2344, hardened HRC 48-52; ±0.01 mm cavity accuracy
- ✓Quick-change insert systems for size families
- ✓Vacuum chamber options for porous-fill prevention
- ✓Mold life guarantee: 300k+ shots with maintenance schedule
Manufacturing Process
CAD → CAM → CNC + EDM machining, with trial runs on our in-house compression presses.
- Cavity layout balanced for simultaneous filling and equal cure
- Preform weight calculation delivered with the mold package
- Insert-quick-change designs let one frame serve a size family
- First-article dimensional layout report with approval samples
Quality Inspection
