If the silicone product is difficult to demold, for convenience, do not use a release agent with better release performance instead, or increase the amount and frequency of use of the release agent. Spraying too much release agent can easily cause the surface of the mold to become dirty, but it may have a certain impact on the appearance of the product. The use of excessive release agent will also affect the adhesion of subsequent screen printing and oiling. If the effect of the above method is not very good, you can consider adding an appropriate amount of internal mold release agent to the compound during preparation, but this will increase the additional cost of the product. In the production process of silicone products, demoulding is the Z key step in the molding of silicone products. No matter who, more or less, will encounter the problem of demoulding difficulties. In view of the production efficiency of silicone products, how to solve the problem of difficult demoulding? The following describes several difficult demoulding methods for reference. Spray mold release agent treatment, silicone products in the molding, silicone products do not stick to which side of the mold mold to spray mold release agent, but sometimes it is not easy to stick. Solution: use a spray bottle or other clean water to spray the product wherever it is desired to stick, and then form it after spraying, and the product will obediently stick to the place you want to stick. The product likes to stick to the lower half of the mold temperature. When the upper mold temperature is 175°C and the lower mold temperature is 165°C, the product is usually stuck to the lower mold when the mold is lifted. Surface Treatment of Mold The molding mold of silicone products should be cleaned before the hydraulic molding machine, especially the new mold that has just been unloaded must be sandblasted. Manufacturers of silicone products choose different washing sand for male and female molds. The mold just after sandblasting must be heated to a sufficient temperature before discharge and molding, and a mold release agent must be sprayed before molding. www.mingzhen2006.com
