Material Selection Guide
Choosing the right rubber polymer compound is essential to ensure longevity and prevent seals from failing under pressure.
Custom Compounding
Tailored elastomer chemistry to achieve specific tensile strength, elongation limits, compression recovery, and hardness classes.
Temperature Range
Dynamic polymer formulations capable of surviving continuous operations in extreme environments from -60°C to +300°C.
Metal-to-Rubber Bonding
Formulating chemical primers and adhesives to create atomic-level bonds between rubber compounds and steel/brass inserts.
Fabric Insertion
Integrating high-strength nylon, polyester, or fiberglass layers into the rubber compound to handle high-pressure diaphragm cycling.
Applications & Custom Capabilities
- In-house Mould Making: Equipped tool room with CNC milling to engineer moulds directly from your CAD files or physical sample.
- Rapid Prototype Runs: Capabilities to configure test tools and run sample batches of custom parts in under 10 days.
- Flash-less Trimming: Post-curing operations, cryo-deflashing, and sorting lines to ensure smooth clean parting lines.
- Quality Assurance: In-house labs to measure durometer, check tensile strength, and verify tolerances under magnifying camera systems.
