Metal End Cap – Dual Function of Vibration Resistance and Sealing

Automotive filters, hydraulic filters, or dust collector filter cartridges operate under complex conditions and must withstand vibrations generated during mechanical operation. They endure significant stress, with metal end caps located at both ends of the filter, bonded and sealed with adhesive. This effectively enhances the load-bearing capacity of the filter material and provides a sealing function, significantly improving the performance and service life of the filter material. PLM Filter offers customized production of metal end caps for OEM and aftermarket manufacturers. According to customer requirements, stainless steel plates, galvanized steel plates, and anti-fingerprint steel plates are stamped into various shapes to meet diverse customer needs.

In the field of metal end caps for filters, we have extensive experience and expertise, supported by a complete production system and a professional technical team and engineers, earning high praise among both new and old customers.

Professional Advice

In the field of metal end caps, we offer three material options: galvanized steel plate, stainless steel plate, and anti-fingerprint steel plate. We will recommend products based on your specific application. You can refer to the following suggestions:

  • Firstly, galvanized steel. It features good corrosion resistance, a smooth and aesthetically pleasing surface, and is cost-effective. If you are looking for the most cost-effective product, this is the one.
  • Secondly, stainless steel. It has excellent corrosion resistance, good mechanical properties, and high-temperature resistance, but it is more expensive than galvanized steel. If your product operates under harsh conditions, stainless steel is your best choice.
  • Additionally, there is fingerprint-resistant steel. Fingerprint-resistant steel is coated with a fingerprint-resistant layer on the surface of stainless steel or galvanized steel. This coating can reduce the adhesion of fingerprints, stains, and oil, keeping the surface clean and aesthetically pleasing, and is typically used in applications requiring high appearance standards. If customers have special appearance requirements for the product, you can choose this material.

We are committed to providing you with the most professional service and the highest quality products, and we look forward to cooperating with you. If you have any questions or needs, please feel free to contact us.
