Frequently Asked Questions

Q: How do I choose the right material for my rubber plug?

Material selection depends on the working medium (oil, seawater, chemicals) and operating temperature. We provide a "Common Material Performance List" and offer professional recommendations based on your specific application.

Q: What information is required for a custom rubber part quote?

We typically need the material, dimensions (drawing or sample), hardness, color, and order quantity. If you have special requirements for precision or elongation, please let us know.

Q: Can you manufacture parts if I only have a physical sample?

Yes. We can use professional Optical Projectors to measure your sample and create accurate 3D drawings for the manufacturing process.

Q: What is the delivery time for custom rubber end caps?

If the mold is already in stock, delivery takes 5-7 workdays. For entirely new designs requiring new molds, the lead time is typically 10-15 workdays, depending on the order quantity.

Q: Do you offer samples before bulk production?

Yes, we can supply samples from our ready stock. Customers are typically responsible for the courier cost and sample cost, though some samples may be provided free of charge.

Q: Which industry certifications do your rubber products hold?

Our factory is certified under ISO/TS 16949:2009 and ISO 9001:2008, ensuring that our custom rubber parts meet international quality management standards.
