Do you know the characteristics and production process of the prototype of soft rubber parts? I believe this is the question of most people. Therefore, the following is a brief introduction for everyone by the Xiehe rapid prototype processing factory.

Soft rubber is made of plastic through injection molding. It feels soft at room temperature. Many people call it "soft rubber", but it does not need to be vulcanized. Making soft rubber prototypes is mainly processed by silicone composite molding. Its advantages are fast time, low cost, easy operation, no deformation, no shrinkage, easy mold removal, smooth mold surface, good simulation effect, and low probability of processing failure. wait. A silicone mold can be used to reproduce 10-20 pieces of the same product. Generally, a set of silicone molds can only be made about 10-20 times before it can’t be used. If it is used again, it may be deformed and the size error will be large. Because of these excellent properties, the soft plastic hand model has a wide range of applications, including but not limited to aviation, military technology, automobiles, machinery, construction, electrical and electronic, chemical and light industry, textiles, leather and paper, Medical and so on. Soft rubber has many characteristics such as physiological inertia, weather resistance, temperature resistance, low surface tension, electrical insulation performance and low surface energy. In the general plastic industry, PE and PP belong to soft rubber, and plastics with relatively low surface hardness are all It is called soft glue, while plastics such as PS, ABS, and rigid PVC can be called hard glue.

The production steps of the soft rubber hand model can be divided into three steps. Before making the silicone mold, the prototype must be made first. The prototype can be made of the more common ABS material, which can be made by cnc processing or 3D printing; after the original version is ready, Start to make the silicone mold. After curing, cut the silicone mold and take out the prototype. At this time, the silicone mold is ready; inject the liquid material into the silicone mold and dry it. The service life of the silicone mold is about 10-20 times.

The above content is the characteristics and production process of the prototype of soft rubber parts. I hope it can be helpful to everyone.
