2. The hot runner mold manufacturing process equipment requirements, hot runner mold precision machinery needed to ensure that, integrated with hot runner systems meet the requirements of the mold is very strict, otherwise, there will be a lot of serious mold problems in the production process, such as a plastic seal bad cause damage to the hot runner components plastic overflow interrupt production, inserts the nozzle and the gate leading to a serious decline in the relative position of poor quality products;

3. The operation and maintenance of complex, compared with TZM cold runner mold, TZM hot runner mold operation and maintenance of complex, such as the use of hot runner components are easily damaged by improper operation, so that production can not be, causing huge economic losses, hot runner mold for TZM New users take a long time to accumulate experience.
