The core of the press maintenance work is the determination of the fault and the handling of the fault. It involves a wide range of knowledge, a large degree of complexity, and a certain depth (such as comprehensive professional knowledge). It is necessary to have basic knowledge of mechanical equipment maintenance, basic knowledge of hydraulic maintenance, and basic knowledge of electrical maintenance. Actually, the maintenance work of the injection molding machine is hard, but it is a process of continuous learning and progress. As long as you grasp the basic working principle of the injection molding machine and grasp the basic working methods, regardless of the various models, you can explore a set of repairs. Work procedures come to ensure the normal operation of the injection molding machine.

The maintenance worker must first understand and grasp the contents of the operation manual of the injection molding machine, familiarize with and grasp the mechanical parts, circuits and oil paths of the injection molding machine, and understand the working process of the mechanical, electrical circuit and oil circuit of the injection molding machine during normal operation. Grasp the inspection and maintenance methods of electrical components and hydraulic components. Clear normal working conditions and abnormal working conditions to avoid time-consuming misjudgment and mis-disassembly.

Maintenance work must understand the handling of the equipment and the basic knowledge of injection molding, and the correct use of the injection molding machine. If you do not know how to operate the injection molding machine, the inspection work is very difficult, and the determination of the failure may also be unreliable. The circuit board and electrical components in the injection molding machine are affected by high temperature, environment and time for a long time. The working point of the device is offset and the aging degree of components is within the normal range. Therefore, debugging the injection molding machine is also one of the essential skills in the maintenance work. Knowing the working procedures of the injection molding machine, debugging the electronic circuit of the injection molding machine and the hydraulic oil circuit are very important links.
