Frequently Asked Questions

We manufacture components using a comprehensive list of standard and high-performance elastomers. This includes EPDM, Nitrile (NBR), Natural Rubber, Neoprene (Chloroprene), Silicone, Viton™ (FKM), SBR, and Fluorosilicone. Compound selection is tailored to your temperature, sealing, and chemical resistance requirements.

Selecting the correct material depends on environmental exposure factors (high/low temperatures, direct UV rays, ozone, oil or fuel contact) and mechanical requirements (tensile force, hard or soft durometers, abrasion cycles). Our engineers will analyze your application environment to recommend or mix a custom elastomer compound matching your target specifications.

We utilize three primary molding techniques depending on part complexity and production volumes: Compression Molding (best for large gaskets and low-to-medium runs), Transfer Molding (ideal for complex shapes and metal bonding), and Injection Molding (for high-volume, high-precision component runs). We also support continuous profile extrusion.

Yes! PRW features an in-house tool design and CNC mold-making workshop. This allows us to manufacture precision molds directly from 3D CAD drawing files, implement changes rapidly, and significantly reduce tool fabrication lead times.

Typically, tool development and prototype sample runs are completed within 2 to 3 weeks from engineering approval. Once prototype samples are verified and signed off, standard production runs are delivered within 3 to 4 weeks, depending on batch volume and compound blending requirements.

Yes, all our standard raw material compounds and elastomeric formulas are fully REACH and RoHS compliant. We strictly avoid toxic or restricted hazardous substances in our compounding process, making them safe for sensitive electrical, food-grade, or medical assemblies.

Quality is verified at every stage of production. Raw elastomer compounds are tested for cure speed and viscosity using a Moving Die Rheometer. Molded parts are checked for Shore hardness, visual defects, and critical tolerances. We also perform tensile strength tests, elongation trials, and heat ageing runs to verify performance parameters.
