Many times, after purchasing a silicone product, we often feel dissatisfied with it, whether it is color difference, hand feel, odor, etc. There are certain differences, because for the silicone product industry, there are many processes from production to oil spraying to printing for a product. Therefore, many silicone products will be baked at high temperatures after production. The products that need to be baked are generally common ones that we often come into contact with, such as silicone jewelry, silicone kitchenware, silicone household products, etc., which have high requirements for the product. However, some special industrial silicone adhesives, suitable for medical grade or food grade products, also need to be baked.
In order to meet the various testing requirements required by customers and satisfy them, the baking personnel in the molding department are almost busy frying the pot, from baking to cleaning the products every day, even rushing to eat! So the difference between food grade silicone products and ordinary silicone products lies in their odor, hand feel, and aging performance. During the baking process, various problems are inevitable that can lead to product defects, such as discoloration, deformation, and even burnout. So when baking, it is still necessary to pay attention to some details.
After being placed in the oven, if the temperature inside the oven is too high, the flowability of the raw materials of the product will be poor, which will cause deformation of the product. Secondly, the reason for whitening is also due to discoloration caused by high temperature. If the baking time is too long, discoloration and yellowing will also occur. In recent observations, there are also certain influences in the raw materials, such as the fact that the raw material belongs to high-temperature adhesive but the colored adhesive is not heat-resistant, which can also cause discoloration and whitening of the product. Secondly, during the baking process, the product closest to the high-temperature port is more likely to be found defective, and if the baking time is too long, it is easy to catch fire.
