The processing of the steel pipe

During the driving of the car, there will be a lot of waggle due to the mechanical vibration of the engine, the transmission itself, and the unevenness of the road surface. In order to suppress the waggle and isolate them from the body and the cab, many rubber and metal parts are installed on the car. Of the nearly 10,000 parts in a car, about 5% are rubber parts in various combinations, such as rubber suspension elements that connect the body to the engine and transmission, shock absorbers strut mount, suspension link rubber bushing etc.

The main function of these rubber-metal components in the suspension system is to make the suspension components move in a predetermined direction and transmit various forces on the one hand, and to suppress various vibrations and isolate various noises on the other hand. All in all, they are important for the steering, braking and driving stability of the vehicle, especially when driving on bumpy roads.

GJ bush is a professional automotive rubber metal components supplier, mainly focus on rubber bushing and rubber mount products. Today we will share the processing of the steel pipe to make a rubber bushing.

1. Purchasing raw material

2. Cutting pipe

Automatic pipe-cutting machine

3. Machining (Refine the length, chamfer)

Automatic double end chamfering machine

CNC lathe

4. Phosphorization (Surface treatment, granding, heat treatment etc)

  Our new factory have set up a set of automatic phosphorization production line.

5. Adhesive coating twice

6. Rubber mixing, design different rubber formula to meet customers’ performance.

7. Vulcanization, the most important part during the production process of rubber bush. Time, temperature, pressure, rubber volume, these are key points.

8. Shrinkage, reduce the stress of rubber during heat expansion & cold contraction, the performance is improved by 50% when durability test.

9. Remove flash

10. Package
