1. Shorten Product Molding Cycle 
 Without the limitation of cooling time of the runner system, the product can be ejected immediately after molding and solidification. The molding cycle of many thin-walled parts produced with hot runner molds can be less than 5 seconds. 
2. Save Plastic Raw Materials 
 In pure hot runner molds, there is no cold runner, so there is no production waste. This is particularly significant for application projects with expensive plastic prices. In fact, major international hot runner manufacturers have developed rapidly in the era of expensive oil and plastic raw materials in the world. Because hot runner technology is an effective way to reduce waste and material costs.
3. Reduce Defective Products and Improve Product Quality 
 In the hot runner mold molding process, the temperature of plastic melt is accurately controlled in the runner system. Plastic can flow into each mold cavity in a more uniform state, resulting in parts with consistent quality. Parts molded by hot runner have good gate quality, low residual stress after demolding and small part deformation. Therefore, many high-quality products on the market are produced by hot runner molds.
4. Eliminate Subsequent Processes and Facilitate Production Automation. 
 After molding by hot runner molds, the product is a finished product, without processes such as trimming gates and recycling cold runners. It is conducive to production automation. Many product manufacturers abroad have combined hot runner with automation to greatly improve production efficiency.
