Frequently Asked Questions (FAQs)
Frequently Asked Questions About Bonded Seal Washers Factories in China
What is a bonded seal washer and how does it work?
A bonded seal washer is a type of washer that combines a metal ring with an elastomeric (rubber) ring bonded inside its diameter. This design prevents over-compression and deformation of the elastomeric ring, ensuring reliable sealing in both low and high-pressure applications. The elastomeric part acts as a gasket, providing the sealing action when compressed between the faces of the parts on either side of the washer.
What materials are commonly used in bonded seal washers?
Bonded seal washers are typically made from a combination of materials. The metal washer can be carbon steel, zinc/yellow zinc plated, or stainless steel, while the elastomeric ring is often made from nitrile rubber (NBR), fluoroelastomer (FKM), or ethylene propylene diene monomer (EPDM). These materials offer high and low temperature capabilities and resistance to various media such as mineral-based oils and hydraulic fluids.
What are the advantages of using bonded seal washers?
Using bonded seal washers offers several advantages. They provide reliable sealing in both low and high-pressure systems, reduce bolt torque without losing tightening load, and can operate across a wide temperature range. Additionally, they simplify machining and use compared to other seals like O-rings because the parts do not need to be shaped to retain the gasket.
Can bonded seal washers be customized for specific applications?
Yes, bonded seal washers can be customized to fit specific needs. Manufacturers in China offer the ability to produce bonded seals in various sizes and material combinations. Some designs also include an additional flap of rubber for self-centring, and you can request custom shapes and materials to suit your particular application.
What kind of quality and certification can I expect from Chinese bonded seal washer manufacturers?
Chinese manufacturers of bonded seal washers often adhere to high-quality standards and certifications. Many of these products are CE and ISO certified, ensuring they meet industry standards for safety and quality. Manufacturers also focus on customer satisfaction, provide professional technical services, and continuously innovate and improve their production processes to meet evolving market needs.
