Factory customization filter end caps aluminum Filter Cap

The filter end cap is an important part of the filter, usually made of steel plate, plastic or foamed polyurethane. It is used to seal both ends of the filter material, support the filter material, and ensure that the fluid is filtered through the filter element to ensure the normal operation of the filter.

The filter end cap mainly serves to seal both ends of the filter material and support the filter material. It stamped into various shapes as needed from the steel sheet. The end cap is generally stamped into a groove on which the end face of the filter material can be placed and an adhesive can be placed, and the other side is bonded with a rubber seal to function to seal the filter material and seal the passage of the filter element.

1. For the production, Dongjie Supplied filter end caps include filming, molding, blanking sheets, and punching. The picture of the production process is as below:

2.The materials used to produce filter end caps include galvanized steel, anti-fingerprint steel, stainless steel, and many other materials. The filter end caps have various shapes as different needs. Each of the three materials has its own advantages.

Galvanized steelis coated with zinc oxide to prevent rusting since the chemical compound takes far longer to corrode than steel. It also changes the steel’s appearance, giving it a rugged look. Galvanization makes the steel stronger and harder to scratch.

Anti-fingerprint steel is a kind of composite coating plate after fingerprint-resistant treatment on the surface of galvanized steel. Because of its special technology, the surface is smoother and it is non-toxic and environmentally friendly.

Stainless steel is material that anti-corrosion to the air, vapor, water and acid, alkali, salt, and other chemical corrosion media. The common kinds of stainless steel include 201, 304, 316, 316L, etc. It has no rust, long service life, and other characteristics.

4. Applications

The filter element is mounted on a vehicle, engine or mechanical device. During the operation of the machine, vibration is generated, the air filter is subjected to a large stress, and the end cover can effectively improve the bearing capacity of the material. The filter end cover is generally used in the air filter, dust filter, oil filter, truck filter, and active carbon filter
