How to deal with silicone mold difficult demould?

Theoretically silicone mold is easy to demould due to silicone rubber's flexibility. And in the process of making silicone mold, molding is the key step. But many customers reflect that they often encounter the phenomenon of silicone mold difficult demould, especially for those silicone mold with fine patterns or complex structures, which has effect on the productive efficiency of products. So, what is the reason and how to deal with silicone mold difficult demould?   There are many influencing factor for silicone mold difficult demould. In the first place, the surface of silicone mold selected as model is needed to be processed, particularly for those mold species with rough surface or complex structure, which can be polished, grinded and cleaned. Coarse model is more likely to occur this phenomenon of mucous membrane than smooth silicone mold.   Next, please don't forget to spray a layer of release agent on the surface of silicone mold and the base uniformly. The release agent most commonly used is petrolatum, detergent and liquid paraffin. You ought to select different release agent on the basis of material of silicone mold during the practical operation. It is unwise of many people to increase the usage of demoulding agent and using frequency to overcome the problem of silicone mold difficult demould. Excessive spraying release agents are likely to cause the dirt of silicone mold's surface, ranging from some impact on the appearance of the product. Most of the release agent has certain influence on the product of subsequent screen printing and fuel injection, excessive use of release agent will also affect the adhesion ability of screen printing, spraying, and printing ink. Therefore, we also need to solve the silicone mold difficult demould by following several ways.   On the third point, the difficult demould is closely related to the structure of silicone mold. Such problem of silicone mold difficult demould does not apply to those products which is sutable for wrapping operation, such as making simple crafts. But for those products of complex structure, such as tire mold, you should take the parting time into consideration. The tire silicone mold is made, which is divided into six pieces.   Besides, you should think over this factor of hardness of silicone rubber, which must be consistent to the size of the products. The soft silicone can be applicable to those small size products with detailed patterns to deal with the phenomeon of silicone mold difficult demould. Of course, it has a knack of adjustment of the operating temperature. Products like stuck in this half of silicone mold with lower temperature. For example, when the temperature of the upper silicone mold is 175 ℃ and the lower silicone mold is 165 ℃, the products generally are stuck in the lower silicone mold.   Shenzhen Hong Ye Jie Technology Co., Ltd is the global leading silicone rubber manufacturer. Our company has a lot of reasons to be confident. For example, this increase in exports bears testimony to the reliability of our silicone raw material, 0% customer complaints rate demonstrate convincingly that our services are professional and satisfactory, and 100% customer satisfaction has benefited from free technical guidance of making silicone mold.
