The Reasons for poor size when making silicone products

The difference in the size of the silicone product during the production is considered to be poor in functionality. Unlike silicone products with poor appearance, once the size of the silicone product is abnormal, it will face scrapping, and there is almost no possibility of repair. Therefore, in the process of producing silicone products, special attention needs to be paid to control the abnormality of the size. Once the cause is found, the problem is easily solved.

What is the reason that the size of the silicone product is so different from the original one?

  • Mold temperature: Excessive molding temperature will accelerate the vulcanization of silicone products, resulting in the fluidity of silicone products in the molding mold, resulting in small size and thick thickness of silicone products.Note: When the molding temperature is too low, the size of the molded silicone product is too large and the thickness is too thin.
  • The weight of the molding compound: Excessive discharge of rubber leads to foaming of the silicone product (air packaging), high and poor loading of the silicone button, resulting in the size of the silicone product is too large.Note: The light weight of the discharge compound leads to the small size of the silicone product after molding.
  • Pressure: Causes the load of the silica gel buttons to be poor, resulting in poor size of the silica gel products.Note: 1. When the molding pressure is too high, the size of the silicone product is too long. 2. When the pressure is too low, the size of the silicone product is small and the thickness is thick.
