With the rapid development of industry, the variety and output of silicone rubber products are increasing day by day, which promotes the mold design, manufacturing technology and processing and production technology of model products of silicone rubber products to gradually develop from the stage of experience design to the stage of theoretical calculation design, especially to the direction of high efficiency, automation, precision and long life.
In recent years, the development of silicone rubber model products at home and abroad has the following characteristics:

1、 Centralized varieties, specialization, serialization, high standardization and large production scale.

2、 In order to ensure the product quality and improve the production efficiency, especially to ensure the coordination of mold design, manufacturing and use, most of the silicone rubber product factories are equipped with special forces to design and manufacture molds. Some or most of the molds are processed by themselves, and special attention is paid to the manufacturing and research of flash free molds. The common characteristics of mold development are precision, multi mold cavities, and most small size products are about 100 holes, which are used together with the host machine, The mold automatically exits, and the products are automatically ejected or blown out with compressed air.

3、 The mold of silicone rubber products is developing towards mechanization and automation. In the production of molded silicone rubber products, the simple manual operation has been basically eliminated. In particular, the reform of semi-finished product preparation vulcanization and trimming processes has greatly improved the production efficiency. The semi-finished products are mostly formed by mechanized operations such as precision pre molding machine, strip cutting machine and punching machine, The edge trimming process generally adopts mechanized processes such as freezing edge removal and grinding, cutting and punching. The use of scissors and blades for edge trimming has been basically eliminated.

4、 The production efficiency of silicone rubber product mould is high. Due to the high degree of variety concentration and specialization, a large number of mechanized automation equipment are used, which greatly improves the production efficiency.

5、 Pay attention to the research of experimental technology transformation. Most silicone rubber product factories and manufacturing companies have two experimental institutions, one is the material laboratory, which is engaged in formula process research, physical and chemical testing and production control, and the other is the finished product laboratory, which conducts simulation experiments and structural research technology transformation of silicone rubber parts, and vigorously adopts new technologies, new processes, new equipment and new materials.
