Frequently Asked Questions (FAQs)

Frequently Asked Questions About O-Ring FPM Factories in China

What materials are commonly used for o-rings in Chinese factories?

Chinese o-ring factories often use a variety of materials, but the most common ones include NBR (Nitrile Butadiene Rubber), FKM (Fluororubber or Viton), Silicone, EPDM (Ethylene Propylene Diene Monomer), and HNBR (Hydrogenated Nitrile Butadiene Rubber). Each material has its own unique properties and is chosen based on the specific application and environmental conditions.

How do I choose the right size for my o-ring needs?

To choose the right size, you need to specify the inside diameter (ID), outside diameter (OD), and the cross-section (CS) or width of the o-ring. The formula to calculate the OD is: OD = ID + CS * 2. You can refer to international standards like AS568, ISO 3601, or other country-specific standards to ensure you get the correct size.

Can Chinese o-ring factories produce custom o-rings?

Yes, many Chinese o-ring factories offer custom o-ring production services. They can create o-rings according to your specific design, size, material, and color requirements. This includes encapsulated o-rings, backup-rings, x-rings, and other specialized types. Custom orders often come with competitive pricing and fast delivery times.

What certifications should I look for in a Chinese o-ring factory?

When selecting a Chinese o-ring factory, look for certifications such as ISO 9001 for quality management, ISO 13485 for medical devices, and IATF 16949 for automotive quality. These certifications ensure that the factory meets international standards for quality and reliability.

How do I ensure the quality of o-rings from Chinese manufacturers?

To ensure quality, check if the manufacturer has certified compounds that meet specific market standards, such as ASTM D200. Also, look for factories with certified laboratories that can develop and test compounds according to your specifications. Additionally, check for customer reviews and ask for samples before placing a large order.
