Analysis of product characteristics of rubber parts

Issuing time:2019/7/23 11:48:36

We know that rubber fittings are widely used because of their excellent performance, so today we will analyze the performance of rubber fittings together!

1. The rubber parts are made of rubber raw materials and mixed with rubber. The rubber is made of rubber. The rubber is used as a raw material according to the characteristics of the rubber parts required, and the hardness of the required product is determined. The product is molded and molded by a rubber flat vulcanizing machine. After the product is formed, it is processed by flashing to smooth the surface of the product without burr.

2. Rubber is a hot-melt thermosetting elastomer, and plastic is hot-melt and cold-set. Because of the different types of sulfides, the temperature range of the curing of rubber is also quite different, even due to climate change, indoor temperature and humidity. Therefore, the production conditions of rubber parts need to be adjusted at any time. If not, the quality of rubber parts may be different.

3. When the rubber parts are molded, after the large pressure is pressed, the cohesive force prepared by the elastic body cannot be eliminated. When the mold is released from the mold, the extremely unstable shrinkage is often generated, and it takes a period of time to be stable and stable. Therefore, when a rubber fitting is designed at the beginning, regardless of the formula or the mold, it is necessary to carefully calculate the fit. If not, the size of the rubber fitting is likely to be unstable, resulting in a low quality of the rubber fitting.
