Silicone rubber products mold classification what are the specific? I want to do to find a manufacturer to do

Silicone rubber as raw material with molds at high temperature and high pressure, after vulcanization oil pressure made of silicone rubber products, called silicone rubber molded products. Silicone rubber products application industry in many industries, such as: automotive industry, household daily necessities industry, electronics industry, medical industry, etc. are used to get silicone rubber products; the production of these silicone rubber products need to open different molds to open the production process. So in the silicone rubber mold design is very important, silicone rubber molds according to the structure of the product, performance and other characteristics of the analysis and design, choose the best materials, dimensions to be accurate and other process design in order to ensure that the mold's efficiency and service life, to ensure effectiveness.

Of course, the silicone rubber product mold molding method method is not the same, the specific classification can be divided into filling pressure mold, pressure injection mold and injection mold 3 categories.

First of all, let's talk about filling pressure silicone rubber mold: that is, the industry is called filling pressure mold, silicone rubber raw materials loaded into the mold, and then through the plate vulcanizing machine heating, pressurized vulcanization of the system. It is worth noting that the filler mold can be divided into three kinds:

1. Open filler mold: the biggest advantage of this mold is the low cost, the structure is easy; but this kind of mold is easy to lead to the loss of raw materials, but also a relatively large, there will be difficult exhaust problems. So dealing with such molds need experienced engineering masters.

2. Closed filling mold: this mold has a charging cavity, the upper mold has a guide, in the process of high temperature compression of silicone products will not appear in the loss of raw materials, but the rubber material by the pressure, resulting in product pieces of high densities, the advantages of relatively small amount of glue consumption. But at the same time there is also the problem of exhaust difficult, and the mold precision requirements are high, while the cost of opening the mold is also very high.

3. Semi-closed filling pressure mold: this type of mold has easier exhaust, there will be no loss of excessive glue problems; but there are problems of poor fluidity.

Lastly, let's talk about the pressure injection mold, the principle of this mold is to put the silicone rubber raw materials into the compression chamber, using the plunger to transmit the pressure, through the injection of rubber channel mouth will be pressed into the cavity of the silicone rubber raw materials and silicone rubber products. Therefore, the pressure injection mold is currently the most manufacturers use the mold, because the mold made of silicone rubber products, high density, stable product quality, suitable for a variety of complex processes Gu silicone rubber parts.
