Production air spring steps
1. Rubber mixing: sports and rubber processing
2. Making rubber bellows: usually one layer of rubber inside, two layers of cord in the middle, and one layer of rubber on the outside. Then connect them together by fixing the mold.
3. Use molds to make other molding accessories, such as plastic parts, iron seats, aluminum seats, iron plates and other hardware accessories
4. Bellows and other accessories are mechanically assembled to make air springs.
5. Air tightness test: Fill the produced air spring with air every time, and then put it into water to test whether it is bubbling and leaking.
6. Quality monitoring: blasting test, fatigue test. The blasting pressure of the air spring in the GUOMAT factory is as high as 30 atmospheres, and the fatigue resistance reaches 3 million times, reaching international standards.
7. Packaging and transportation: Qualified products are usually packaged in carton boxes. Some special solid wooden boxes are required, and others are labelled and packaged according to customer requirements.
