Discussion on the Problem of Breakable Nozzle of Integral Hot Runner
Abstract: Nozzle fracture of hot runner severely affects the overall service life of hot runner, restricting the promotion and application of hot runner technology in the mold. In this paper, we discussed the fracture problem in order to solve it. Taking into account the structure and use environment of the nozzle, four main factors of the fracture problem were summarized: threaded connection defect, temperature effect, needle valve shock, and injection pressure. And then each impact factor was calculated in detail. Aiming at the fracture, three improvement projects were also proposed. Frac-ture had been reduced significantly in the improved hot runner system, greatly enhancing the re-liability and service life.
