In general, injection molding machine The reliability of the circuit board is good and the failure rate is low. 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 PLCs. Pay attention to scratches, missing parts, looseness, etc., whether the movement of the mold to the sliding plate is true, whether there is leakage at the water channel and gas pipe joints, whether the mold opening is restricted, and whether the mold should also be marked. If the above actions can be completed before the formwork hanging, the problems found in the formwork hanging process and the waste of working hours caused by demoulding can be avoided.

In the work of 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 the elements you need to know when purchasing equipment.

PCB and electrical components are affected by high temperature, environment, time and other factors for a long time; The working point deviation and aging degree of parts are within the normal range. It is very important to do a good job in the maintenance of the injection molding machine debugging, 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 use of subsequent plastic processing equipment and increase the service life of the equipment.

Each time the mold is closed, open the mold to make the gap between the upper and lower molds stick. If the mold is fully opened, the machine will be in working condition due to the weight of the upper platen and the mold. It affects the service life of oil seal valve and other components. Before fixing the mold, remember to check whether the mold and the fixing surface are clean. Wipe clean if necessary.
