Frequently Asked Questions (FAQs)
What are the common materials used by o-ring factories in China?
O-ring factories in China use a variety of materials, including Nitrile (NBR), Fluororubber (FKM), Ethylene Propylene Diene Monomer (EPDM), Silicone (VMQ), and Hydrogenated Nitrile (HNBR). Each material has its own set of properties and is suited for different applications, such as resistance to oil, chemicals, or extreme temperatures.
How do I determine the correct size of an o-ring for my needs?
To determine the correct size of an o-ring, you need to know the inner diameter (ID) and the cross-section (CS) of the o-ring. The outer diameter (OD) can be calculated using the formula: OD = ID + 2 x CS. You can refer to standard o-ring size charts, such as AS568, ISO 3601, or DIN 3771, to find the appropriate dimensions.
Can Chinese o-ring factories produce custom o-rings?
Yes, many Chinese o-ring factories offer customization services. If you need o-rings with non-standard sizes or shapes, you can provide the factory with your specifications, drawings, or samples. They can produce custom o-rings in various cross-sections and shapes, including square, rectangular, or other irregular shapes.
What is the typical lead time and minimum order quantity (MOQ) for o-ring orders in China?
The lead time for o-ring orders can vary depending on the factory and the complexity of the order. Generally, it can range from a few days to several weeks. The minimum order quantity (MOQ) is often around 100 pieces, but some factories may accommodate smaller orders, especially for standard sizes.
How can I ensure the quality of o-rings from Chinese manufacturers?
To ensure the quality of o-rings from Chinese manufacturers, look for suppliers with verified business licenses and certifications such as ISO 9001, ISO 14001, and TS 16949. You can also request free samples for testing and check the factory’s production methods and material quality. Additionally, consider contacting top-rated manufacturers that have a reputation for delivering high-quality products.
