[0002] Rubber and plastics are collectively referred to as rubber and plastics. With the development of society, the application of rubber and plastic products is becoming more and more widespread in society. Rubber and plastic products do not exist naturally, but are made by using production equipment to make rubber and plastic raw materials into rubber and plastic products. With the development of science and technology, people have put forward higher and higher requirements for the daily necessities they use, including the high performance and intelligence of products. They are not only required to be beautiful, but also to ensure reliable safety, easy use and maintenance, and long service life as much as possible under the premise of low cost. Among them, the improvement of product level is not only related to the further improvement of its own performance, but also depends on the development of various components to realize its overall function. Rubber and plastic products have become one of the important components of most product equipment due to their good sealing performance. Usually, rubber and plastic products with specific structural shapes can be processed by molds to make standard parts, but the rubber and plastic products need to be melted before mold processing.
