What are the main defects of silicone products?

With the increasing recognition of silicone rubber products, silicone rubber products have become a regular on the purchase list of many manufacturers. However, there are too many silicone rubber suppliers in the market, and their levels are different, so it is very necessary for a boss or purchaser to master some silicone rubber knowledge. Now Xiaobian will popularize what are the main defects of silicone products.

In the production process of silicone rubber products, it is inevitable that there will be defective products. Whether the manufacturer's management on production is in place affects the level of the defective rate, which is also the reason why we should find powerful manufacturers. If the defect rate is high, the product must be returned for repair. How to write the reason for the return defect?

1. Gas accumulation (bubble) this kind of defect will form fine bubbles inside the product, which cannot be repaired and needs to be scrapped. It is caused by the short molding time of the operator and the low mold temperature.

2. Black spot stains the main causes of black spot stains are mixing dirt into the refining material, the production environment is not clean enough, and the operator's hands are dirty. Therefore, experienced manufacturers will put a piece of sticky material on the table for operators to clean their hands.

3. Embrittlement and press hemp forming time can not be adjusted at will. Too long high-temperature forming time will make silicone products numb and bent, difficult to process, easy to break, and poor hand feel.

4. The immature molding time is short, resulting in incomplete maturation, and there will be siltation on the surface, which will fall off with one button. It can be solved by prolonging the molding time.

5. Burrs and burrs: silicone products need to be disassembled. If the burrs are not removed, the edges will be uneven and the appearance will not be beautiful. The manufacturer can be notified to repair them.
