Do you know the reason why silicone rubber products are defective during production? Let's follow the Wholesale silicone rubber for moulds editor for a brief introduction!
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. Product defects caused by the molding machine:
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 cardboard and silicone mold pads can be placed on the machine template;
The above is the editor of Wholesale silicone rubber for moulds: the introduction of the reasons for defective silicone rubber products during production.
