Frequently Asked Questions

Q: How do I choose between EPDM and Silicone for my rubber stopper?

Choose EPDM if you need excellent weather resistance, UV protection, or exposure to steam. Choose Silicone if your application requires food-grade certification, extreme temperature stability, or resistance to vegetable oils.

Q: Can you manufacture rubber plugs based on a 3D CAD drawing?

Yes, our professional technology team and engineers can work directly with your CAD drawings to design precise molds for OEM and ODM requirements.

Q: What is the lead time for custom rubber part production?

Lead times vary based on mold complexity. However, with our monthly capacity of 10 million pieces and a complete supply chain, we ensure timely delivery and regular production updates.

Q: Are your food-grade silicone products certified?

Yes, our food-grade products are compliant with LFGB and ROHS certifications, ensuring they are safe for use in food and medical equipment.

Q: Do you offer free samples for testing quality before a bulk order?

Yes, we provide free samples for the first order of new customers to ensure our material and quality meet your specific industrial standards.

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

For photovoltaic high-temperature diffusion furnaces, we have specifically developed sealing rings capable of withstanding temperatures between 300-400℃, typically using high-end FKM or FFKM.
