The hot runner mold is a new structure that heats the runners and runners of traditional molds or three-plate molds, and does not need to take out the runners and runners during each molding.
Hot runner technology provides huge technical support in saving injection materials, improving product quality, improving productivity and realizing automatic production, strengthening the function of injection machines, and improving productivity to realize automatic production.
For high-volume injection molded products, material costs and waste disposal costs can be significantly reduced because hot runner technology minimizes scrap generation.
Fill pressure can be kept low due to reduced fill pressure losses from cold runners. In addition, the cooling cycle can be shortened.
Application of injection moldhot runner technology
Injection mold hot runner technology has been widely used in food containers, medical supplies, auto parts and many other products. Recently, in the development of super engineering plastic-related molding products with expensive materials, there has been a trend to use valve gates and new types of hot runners.
The main points of the application of hot runner technology in injection molds are the control of plastic temperature and the control of plastic flow. Any plastic material that can be processed with cold runner molds can be processed with hot runner technology.
