Liquid silicone machine-basic production procedure

Author:yswl Date:2021-03-25 Reading:

The material supplier provides a low-viscosity, high-temperature vulcanized dual-group silicon material to be used, packed in 20 or 200KG containers A and B. Using a two-component mixing and batching system, group A and group B are transferred to the mixing pipeline at a ratio of 1:1 under the same pressure under electromagnetic control. At this time, colors and additives can also be added at a ratio between 0.3% and 4% to increase the color or change the characteristics of a certain material or product. Through the static mixer in the mixing pipeline, the reacted material mixture is conveyed to the liquid silicone rubber cylinder under pressure. In order to prevent premature vulcanization in the barrel, the temperature of the liquid silicone rubber plasticizing screw must be specially controlled to make the temperature close to 20~25°C. The material is then mixed again by the screw and then injected into the hot mold. The temperature of the hot mold is between 140°C and 220°C. Due to the low viscosity of the silicone material, the error in manufacturing these molds must be small to ensure that the two parts of the mold are extremely tight and closed. At the same time, in order to prevent problems such as production burning, unsatisfactory filling, and poor air exhaust, the mold is usually vacuumed before injection. The cold runner system is mainly used to obtain the best cycle time and minimize waste. The cold runner system can simplify the automation process and save materials. Pneumatic or demolding robots are more used to eject products that are usually extremely soft and sensitive.
