How to deal with the phenomenon of missing corners and materials in silicone products in the molding process!silicone pacifier

　　For silicone product manufacturers, it is normal to have bad phenomena during production, and there are countless reasons for the bad phenomenon. For example, the lack of materials and corners can be said to be a phenomenon that occurs in many products produced every day. The factors that cause this situation to develop are often man-made, such as the way of placing materials, the control of the weight of raw materials, etc.

　　The most serious reason for the lack of materials and corners of silicone products is that the method of placing the materials is wrong. For products with medium-plate mold cores, it is sometimes necessary to place rubber materials up and down and the number of mold cavities is too deep or too complicated. In other cases, the weight needs to be heavier than the original plan. The placement is the most important, so you can imagine how to place it to make the vulcanization of the rubber more comprehensive to ensure that there is no shortage of materials and corners. For the problem of the mold, the pressure needs to be adjusted during the vulcanization process, otherwise there will be not only lack of material, but even immaturity. The mold cannot be exhausted during the mold closing process, resulting in the occurrence of air and material shortage, and the mold temperature is too high. The high level will cause the rubber material to burn to death, the raw material fluidity is not good, and the product cannot be vulcanized on time!

　　The solutions for various reasons are as follows: the raw materials are placed in the relatively central position. If the upper and lower materials need to be placed step by step, if the mold is unreasonable, the modification can ensure that the rubber material and the mold are properly matched, and the exhaust grooves are opened for more exhaust. , The method of placing the material does not increase the weight of the raw material by changing the method and method. After the vulcanizing agent of the raw material has been placed for more than three days, it must be re-mixed to meet the flow requirements to ensure complete vulcanization. The molding process of silicone products is a complex part. Don't compete with output and speed. Do it first and then do it quickly, otherwise it will be a waste of time to make too many defective products.
