Problems solved by technology

[0002] With the gradual development of industrial production in the direction of multiple varieties, small batches, high quality, and low cost, people began to require control over the development cycle and manufacturing costs of molds. Epoxy resin casting molds are classified according to different structures and uses, such as switches Insulating paper products for cabinets, due to their small size and the need for a large number of molds for the same type of products in mass production, but the accuracy requirements are not too high, the use of epoxy resin casting molds can shorten the molding cycle, and repetitive molds can be mass-produced. Compared with traditional mold materials, the raw materials used in epoxy resin casting molds are light in weight, easy to repair, and cheap, which can significantly reduce the labor intensity of workers. At present, epoxy resin vacuum casting mold technology is widely used in automobile manufacturing, toy manufacturing Industry, home appliance manufacturing, hardware industry and plastic products and other industrial systems are widely used. With the development of new materials and new technologies and the promotion of epoxy resin application technology, the comprehensive performance and manufacturing technology of epoxy resin molds are widely understood and recognized. , coupled with the improvement of the performance of epoxy resin material and the improvement of resin material performance and the simplification of resin mold manufacturing process and application process, epoxy resin mold has been developed by leaps and bounds, becoming a new high-efficiency, low-cost advanced mold, however , the application of molds in the insulation products industry is less
