The problem of remove edge for silicone products
The problem of remove edge for silicone products In the silicone products during the production process, silicone products remove edge is a process is very important, is to remove the edge silicone products edges trimmed, but because the processing technology or raw material itself, causing the product is difficult to remove the side, or not up to remove the side effect is very good, make products appear rupture the bad situation, then what should we do to prevent this situation? 1. (vulcanizing machine)Curing temperature is too low or the curing time is too short. Lead to silicone products become brittle, silicone products in the incomplete vulcanization time soft toughness is very strong, therefore in the demolition side will not easily make the edge and the separation of the product. 2. The curing temperature is too high or the curing time is too long. Silicone products molding once the temperature is too high or curing time is too long, will cause the product after molding numbness or become brittle, no matter is the numbness or brittle, has great influence on the removed edge. 3. Molding thickness too thick. Note: as long as the molding guarantee qualified size to do thin line. 4. Die from demolition design unreasonable or production of poor quality or mold used for a long time been worn When the die mold design unreasonable, making mold from opening not sharp causes after molding the products difficult to remove edge. In addition, die wear during the production process, or blasting can be caused by too many times since opening coarse meal will affect the performance of silicone products from demolition.
In a word, silicone products remove boundary problem is very important, it relates to the product quality and production efficiency, so in the production process should be strict control of mold, molding thickness when not too large and the molding time of curing temperature and time control, finally is sizing problems, not to covet cheap two to choose compound not good, the glue material existence tear strength is insufficient, poor toughness, besides releasing properties will affect the forming cause, but also difficult to remove edge, the more important is that it may cause remove side when the silicone products may rupture.
