The development status and molding process of SMC molding materials

The choice of SMC molding material determines the quality of the sheet molding compound (SMC molding material) to a certain extent. Choosing the right raw materials can meet the special performance requirements of the product, and the molding process is also the most important thing in the manufacture of molded parts. Firstly, the raw material composition of SMC molding materials is introduced, including resins, initiators, low shrinkage additives, chemical thickeners, internal release agents, colorants and reinforcements. The performance requirements for each component are also briefly described; Secondly, the molding process of SMC molding materials is discussed layer by layer, including the type and structure of the film making unit.

 

The production process of SMC molding materials, the molding equipment and processes of SMC molding materials, and the problems of SMC molding material products, this paper draws on several improvement measures from abroad, including surface paint bubbles, inhalation solvents, high density, environmental pollution and zero pollution of automobiles. improvement of parts production lines, etc.; Finally, the industrial application and recycling of SMC molding materials are briefly discussed. I hope you can have a new understanding of SMC molded composites through this article.
