The breakdown part classification: 1. According to the breakdown state, can be divided into:
(1) Gradual failure. It is caused by the gradual deterioration of the initial performance of the injection molding machine. Most of the failures of the injection molding machine belong to this type of failure. This type of failure is closely related to the process of wear, corrosion, fatigue and creep of electronic control and hydraulic mechanical components.
(2) Sudden failure. It is caused by various unfavorable factors and accidental external influences, which are beyond the limit that the injection molding machine can bear. For example: the screw is broken due to the overload of the iron material in the barrel; the electronic board of the injection molding machine is broken due to the high pressure. Such failures often happen suddenly, without any prior warning.
Sudden failures mostly occur in the use stage of injection molding machines, and are often caused by defects in design, manufacturing, assembly, and materials, or operating errors or illegal operations.
