Reasons and solutions for missing corners and materials in the production process of silicone products

The occurrence of missing corners and materials in the production process of silicone products is a common problem that many silicone product manufacturers encounter. Understanding that the factors that may lead to this situation in the future are often human factors, such as the way materials are placed, the weight control of raw materials, and so on.

The reasons for the shortage of materials and corners in silicone products:

Incorrect placement of materials is the most serious cause

For products with a middle plate mold core, sometimes it is necessary to place the rubber material up and down, and in cases where the mold cavity number is too deep or too complex, it needs to be slightly heavier than the original plan. Placement is the most important. Therefore, while placing, one can imagine how to place the rubber material more comprehensively to ensure that there is no shortage of materials or corners.

2. Machine mold issues.

During the vulcanization process, the pressure needs to be adjusted properly. Otherwise, there may not only be a shortage of materials, but also a lack of maturity. During the mold closing process, the exhaust cannot be discharged, resulting in air pockets and material shortages.

3. The mold temperature is too high, resulting in the rubber material being burnt to death, poor raw material fluidity, and the product not being vulcanized on time.

Solution to shortage of materials and corners in silicone products:

1. Place the raw materials in a relatively central position, and if it is necessary to place the materials up and down step by step.

2. If the mold is unreasonable, modifying it can ensure that the rubber material and mold are properly matched, and adding more exhaust slots for exhaust.

3. The material placement method should not be changed, and the method should be changed to increase the weight of the raw material. After the raw material vulcanization agent has failed for more than three days, it must be re mixed to meet the flow requirements, ensure complete vulcanization, adjust the mold pressure and temperature appropriately, and ensure correct personnel operation methods.

The molding process of silicone products is a complex process, so do not compete with production and speed. Do it first and then do it quickly. Otherwise, if there are too many defective products, the effort will be exhausted.
