Rubber Injection Machine Development Trendency.

1. The concept of rubber injection machine was put forward in the mid-1940s; rubber injection equipment in the early 1970s, rubber cold feed injection of rubber injection equipment began to be practically applied in industry. Rubber injection equipment because it can achieve high temperature and rapid vulcanization, the rubber material is preheated and plasticized before entering the mold cavity, and the rubber injection equipment products are molded and vulcanized in the sealed high-pressure mold cavity. The quality of the rubber injection equipment is uniform and stable, and the size is accurate. Realizing fully automatic operation, the production efficiency of rubber injection equipment can be increased by more than ten times compared with the traditional molding method. Therefore, the technology of using rubber injection equipment to produce molded products is increasingly widely used.
2. Rubber injection machines are mainly used in the production of auto parts, industrial parts, electrical insulation parts, connector sockets, seals, shock pads, shock covers, shoes, bottle plugs, vacuum hoses, sheaths, valve pads, toys and Fitness equipment, etc. With the development of the automobile industry, rubber injection equipment has higher and higher quality requirements for seals, electrical connectors, shock absorbers, etc. The demand for rubber injection equipment has increased by more than 12,000 times. The strong market demand is rubber The development of injection equipment provides an opportunity.
3. Rubber injection equipment In the early 1970s, the rubber injection equipment Beijing University of Chemical Technology cooperated with a factory in Shanghai to successfully develop the XZL-200 screw pre-plastic one-line rubber injection equipment molding vulcanizing machine. Rubber injection equipment China has introduced a large number of rubber injection equipment from Europe, America, Japan and other countries. On this basis, domestic manufacturers of rubber injection equipment have also begun to develop and produce rubber injection equipment.

Advantages For Rubber Vulcanizing Machine:

1. Under a certain center distance, it is allowed to install a hydraulic cylinder of a larger diameter, thereby reducing the number of hydraulic cylinders, and having a simple structure and less maintenance;
2. The upper beam is reasonably required, required The section modulus is much smaller than that of the living type, which can reduce the weight;
3. The manufacturing and installation is simple, the pipeline configuration is concealed, and the overall shape of the machine is neat and beautiful.
