molding silicone rubber Manufacturers china introduces the reasons for defective silicone rubber products

Do you know what is the cause of defective silicone rubber products? Follow the editor of molding silicone rubber Manufacturers china to have a brief understanding of it!
1. Reasons for the fog surface of silicone rubber products
1. The time of forming and vulcanization is too short, resulting in a matte surface when it is not cooked;
2. The mixing temperature of the mixer is too high, the air is humid, and the humidity is too high;
3. The vulcanizing agent is completely dispersed due to uneven mixing of the rubber compound for a long time;
4. The speed of placing the raw materials by the molding staff cannot keep up with the temperature of the machine, resulting in a foggy surface of the product;

2. Defective products caused by molding machines
1. The thickness of the raw material is different and the product is not cooked, adjust the pressure of the mold and increase the temperature;
2. When the silicone product is manufactured, there is an inner wind, keep it for a certain time, keep the vulcanization times uniform, and keep the mold at a certain temperature, and you can blow the mold with an air gun to dissipate heat;
3. If the product is outsourced, prolong the vulcanization time, increase the temperature, and replace the die pad;
4. If various defects occur frequently, the mold can be removed, and the cardboard and silicone mold pads can be put on the machine template;
3. Product defects caused by molds
1. The bad phenomenon caused by the sticky impurities in the mold can be wiped with a cloth strip with kerosene;
2. If the mold is bruised, use the sandblasting machine to choose different sands for spraying with different degrees of bruising;
3. When the silicone mold is opened, the mold sticking phenomenon, spray the mold release water to keep the product normal demoulding, long-term spraying will cause the mold to appear foggy, so normal spraying can be done;
The above is the introduction of the editor of molding silicone rubber Manufacturers china: the reasons for the occurrence of defective silicone rubber products.
