How to troubleshoot when checking an injection molding machine?

Generally speaking, the circuit board of the injection molding machine has good reliability and low failure rate. Generally speaking, when checking the injection molding machine, do not doubt the board first. Repeated testing can usually be eliminated by removing the pull, initialization, cold start and hot start PLC. Pay attention to scratches, missing parts, looseness, etc., whether the mold movement to the slide is real, whether there is leakage at the waterway and air pipe joints, whether the mold opening is restricted, and the mold should also be marked. If the above actions can be completed before hanging the mold, the problems found in the mold hanging process and the waste of man-hours caused by demolding can be avoided.

In the work of the injection molding machine, it becomes much easier, so plastic processing equipment is widely used. When purchasing plastic processing equipment, you need to consider many things. The following are those elements you need to know when purchasing equipment.

Circuit boards and electrical components are affected by high temperature, environment, time and other factors for a long time; the deviation of the working point of parts and the degree of aging of parts are within the normal range. It is very important to do a good job in the maintenance of the injection molding machine commissioning, understand the working process of the injection molding machine, and debug the electronic circuit and hydraulic circuit.

In fact, the operation method of plastic processing equipment is not difficult. Generally speaking, it is relatively simple. However, even so, we still hope that everyone can develop good operating habits to facilitate the subsequent use of plastic processing equipment and increase the service life of the equipment.

Every time the mold is closed, open the mold so that the gap between the upper and lower molds is glued. If the mold is fully opened, the machine will be in a working state due to the weight of the upper pressure plate and the mold. Affect the service life of components such as the oil seal valve. Before fixing the mold, remember to check whether the mold and the fixing surface are clean. Wipe it clean if necessary.
