The lack of corners and materials in the production of silicone products is a problem that many silicone product manufacturers will encounter. After understanding, the factors that will develop this situation are often the most human-made, such as the way of placing materials, the weight control of raw materials, etc., Summarize several reasons and treatment methods.


The reasons for the lack of materials and corners of silicone products:

1. Wrong way of placing materials is the most serious reason

For products with middle-plate mold cores, sometimes it is necessary to place rubber materials up and down and the number of mold cavities is too deep or too complicated. It is necessary to increase the weight of the original plan. Placement is the most important, so in While placing it, you can imagine how to place it to make the vulcanization of the rubber more comprehensive and ensure that there is no lack of material or corners.

2. Machine mold problem.

During the vulcanization process, the pressure needs to be adjusted well, otherwise there will be not only a lack of material but even unfamiliarity, and the exhaust of the mold cannot be discharged during the mold closing process, resulting in air entrainment and material shortage.

3. If the mold temperature is too high, the rubber material will be scalded to death, the fluidity of raw materials will not be good, and the product will not be vulcanized on time.


   The solution to the lack of materials and corners of silicone products:

1. The raw materials are placed in a relatively central position. If you need to place materials up and down, you can do it step by step.

2. If the mold is unreasonable, it can be modified to ensure that the rubber material and the mold are properly matched, and the exhaust groove is added to exhaust more.

3. The way of placing the material is not correct. Change the method and method to increase the weight of the raw material. 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 mold pressure and temperature are adjusted appropriately, and the personnel operating method must be correct.


The molding process of silicone products is a complicated process. Don't compete with the output and speed. Do it well first and then make it fast, otherwise it will be a waste of effort to make more defective products.
