Plastic injection products as modern industrial product main structural components in all walks of life, one of many areas already applied widely. In injection molding process, gating system remains cold runner is given priority to, along with the social economy development of science and technology, the cold runner in the molding manufacturing faults is becoming more and more prominent, and less and less fit with the requirement of economic development, and accelerate the development of hot runner. Hot runner has become the modern plastic manufacturing pets, is used widely. The development of hot runner makes up many cold runner of many defects, and this is hot runner become the most popular technology main reasons.
This topic combining refrigerator flats, mainly in the process of plastic injection, detail in the application of hot runner injection. Hot runner system by fluid DaoBan, reflection (insulating layer, surface coating), melt cavity bushings, dispenser bushings, pressure, flow DaoBan circle of wrest resistant device, cock, hot runner nozzle composition. Meanwhile to the refrigerator the lid of the plastics analysis, refrigerator box molding equipment selection, refrigerator the lid of the injection mold design, refrigerator box molding parts, injection mould demoulding mechanism and core-pulling mechanism of design of process on a simple explanation.
Through the design of hot flow path, the use of a basic understanding of hot runner in practical production with manipulating do an action.
