Difficulty in demolding is a common and challenging issue in the production process of silicone products, which not only affects production efficiency but may also reduce product quality and increase production costs. To effectively solve this problem, it is necessary to have a deep understanding of the root causes of demolding difficulties.
There are generally three reasons for difficulties in demolding: the design of the mold is not very reasonable, and the surface roughness of the mold has a significant impact on demolding. If the surface is not smooth, silicone products are prone to adhere to the mold surface after molding; Improper use of release agent, which is a key material for assisting in demolding, but selecting unsuitable release agents or using incorrect methods cannot achieve the desired demolding effect; The characteristics and molding process of silicone materials. Different types of silicone materials have different physical and chemical properties. Some silicone materials have high viscosity and are easy to tightly adhere to the mold after molding. There are also three methods to solve the problem of demolding: optimizing mold design, strictly controlling the machining accuracy of the mold surface during the mold manufacturing process, adopting advanced machining and polishing techniques, reducing the surface roughness of the mold, and ensuring that silicone products can slide smoothly during demolding; Correctly select and use release agents, choose appropriate release agents based on the characteristics of silicone products and production process requirements. When using release agents, ensure uniform and appropriate application, and pay attention to the drying time and fixing conditions of the release agents to ensure the best release effect; Adjust the molding process parameters, accurately control the temperature, pressure, and time during the molding process, determine the optimal vulcanization temperature and pressure range suitable for different silicone products through experiments and data analysis, regularly clean and maintain the mold during production, remove residual silicone and dirt on the mold surface, and also help improve the demolding effect.
Solving the problem of difficult demolding of silicone products requires comprehensive consideration from multiple aspects such as mold design, selection and use of demolding agents, and adjustment of molding process parameters. Only by deeply analyzing the causes of the problem and adopting targeted solutions can we effectively improve the demolding efficiency and quality of silicone products, reduce production costs, and enhance production efficiency.
