Air spring production process:

1. Rubber mixing: exercise and rubber processing
2. The production of rubber bellows: bellows is made of inner is a layer of rubber, the middle is two layers of cord fabric and the outside is a layer of rubber. Through the fixed mold them together.
3. Other forming accessories: plastic parts, iron base, aluminum base, iron plate, and other hardware accessories, these parts have been made in different moulds.
4. The bellows and other accessories are gotten together by machine and make out air spring.
5. Air tightness detection: each production of good air spring fills the air, and then put into the water to test whether the bubbling gas leakage.
6. Quality: blasting test, fatigue test, the air spring blasting pressure GUOMAT factory is up to 30 atmospheric pressure, fatigue to reach 3 million times, meet the international standards.
7. Packing: the qualified products for packaging, are usually carton packaging, need some special strong wooden case packing, others are labeling packaging according to customer's requirements.
