Special silicone products are difficult to demould solution.baby pacifier feeder custom

　　When processing silicone products of special materials, it is difficult to clean the burrs and products due to the product sticking to the mold during the molding process. Greatly reduced our production efficiency. And some special products often have the phenomenon of sticking to the mold, such as some products with low hardness, such as some products that are tightly adhered to the mold, which are neither large nor small. Generally, the mold can open about a hundred or so holes. Products with a hardness of about 30 will be difficult to demould, and there will be a lot of separation after mold release. Self-cutting and breakage cause the products to stick to the mold core and need to be deducted one by one. What are the reasons? ?

　　In the silicone molding silicone process, there are also certain skills for demolding. After the mold temperature reaches the first mold, if there is no spraying of mold release water, it will stick to the mold after vulcanization, so many silicone products are Knowing that the first mold must be added with a release agent, the release agent will be specially used for the release of the product, and it is properly sprayed on the part where the mold sticks to the mold. The release agent is mainly composed of different chemical resins or styrene and styrene. amine, so there is a certain concentration control. Generally, the mold does not need too thick release agent, so you can add some water to the release agent and blend it to a suitable concentration, otherwise the product will also have defects such as weld lines and material flow marks. Phenomenon.

　　The reason for the difficulty in demoulding can be found from the mold. First, the new mold that has just been opened needs to be sandblasted to prevent burrs or mold debris, etc., so sandblasting is performed first. Secondly, in the mold, it is necessary to know whether the self-cutting edge of the exhaust groove and the edge of the mold core is accurate, and whether the development of the mold is reasonable. Generally, the temperature of the lower mold is lower than that of the upper mold. You can make appropriate adjustments so that the product does not stick to the upper mold. The mold release water is sprayed more on the upper mold and less on the lower mold. Secondly, when placing raw materials Try to control the appropriate weight.
