Frequently Asked Questions

Q: Which material is best for high-temperature rubber sealing?

For extreme heat, FKM (Viton) or specialized Silicone is recommended. We offer seals specifically developed for the photovoltaic industry that can withstand temperatures between 300-400°C.

Q: Can you produce rubber washers according to my specific CAD drawing?

Yes, we specialize in OEM and ODM services. Our engineering team can take your custom drawings and create a professional mould for precise manufacturing.

Q: What is the difference between NBR and HNBR seals?

NBR is excellent for oil and fuel resistance, while HNBR offers superior heat and chemical resistance, making it ideal for automotive and industrial applications with higher stress.

Q: Are your silicone rubber products food-safe?

Yes, we provide food-grade silicone seals that are compliant with LFGB and other international food safety certifications, suitable for medical and food-processing equipment.

Q: How do you ensure the quality of custom rubber parts?

We follow a strict process: raw material testing in our lab, pre-production sample approval, and a final total inspection before any shipment leaves our facility.

Q: What is your typical lead time for custom rubber moulding?

Lead times vary by complexity, but we provide 24-hour quick replies during the quotation phase and regular production updates to ensure on-time delivery.
