The end cap of the filter element mainly plays the role of sealing the two ends of the filter material and supporting the filter material. It mainly uses the steel plate according to the demand presses into each kind of shape. The filter element is mounted on the vehicle and the engine, which will produce vibration during mechanical operation, and the air filter will bear strong stress. The end cap can effectively improve the bearing capacity of the filter material. Typically, one side of the end cap is pressed to place the end face of the filter material on the other side of the groove and bonded to the rubber seal, which seals the passage of the filter material and the filter element. The end cap is made of steel, plastic, and polyurethane foam. Filter end caps are suitable for all types of metal plate filters, pressing, casting, machining and galvanizing, anti-fingerprint and plastic materials. For decades, we have focused on metal filter caps. With various end caps for filters, the filter industry is our core business and we are able to build customer recommendations on the appropriate thickness.
There are parts of specifications of filter caps we made for clients before for your reference. If you need other shapes, we could make customization.

The End Cover and inner and outer protecting net of hydraulic oil filter element adopt high quality electrolytic plate, which not only has good strength, but also has good anti-rust and anti-corrosion performance. The advanced connecting technology of inner and outer protecting net does not harm the metal surface of protecting net, so that the anti-rust and anti-corrosion performance of hydraulic oil filter core is further strengthened. At the same time, the filter material of the hydraulic oil filter element is not hurt by the protecting net.
In the process of making, also need to pay attention to is filter paper, filter paper is generally divided into domestic paper and imported paper, grade is divided into high, middle and low three grades! According to the customer here requirements for the selection of FILTER PAPER TO USE! The paper folding should be calculated according to the specification of the filter element, the size of each product is different, so it is not described in detail here! Three: air filter is generally divided into Pu and the two ends of the iron cover, the iron cover needs to be glued, the process is relatively simple! Pu Process is relatively more complex, can be divided into artificial PU, mechanical Pu! To ensure the product at both ends of the cleanliness, hardness, in the production process to be in the dust-free workshop, wearing rubber gloves!
