Fifteen Tips For The Maintenance Of Injection Mould

- Jun 28, 2018-

Compared with other molds, the injection mold has a more complex and precise structure and requires higher requirements for operation and maintenance. Therefore, during the entire production process, the use of positive solutions and meticulous maintenance, maintenance will maintain the company’s normal production and improve the company’s performance. Benefits are of great significance.


First, choose the right molding equipment, determine the reasonable process conditions, if the injection molding machine is too small to meet the requirements, too much is a waste of energy, and will be due to improper mold clamping force to damage the mold or template, while It also reduces efficiency.


When selecting the injection machine, the maximum injection volume, effective distance of the rod, mold installation size on the template, maximum mold thickness, minimum mold thickness, template stroke, ejection mode, ejection stroke, injection pressure, mold clamping force, etc. Verification can be used only when required. Reasonable determination of process conditions is also one of the correct use of the mold, too much clamping force, injection pressure is too high, the injection rate is too fast, the mold temperature is too high will cause damage to the service life of the mold.


Second, after the mold is loaded with the injection machine, it is necessary to first run the mold. Observe whether the movement of each part is flexible, whether there is any abnormal phenomenon, whether the stroke is ejected, whether the opening stroke is in place, whether the parting surface is tightly fit at the time of mold clamping, and whether the platen screw is tightened.


Third, when the mold is used, it is necessary to maintain the normal temperature and work at normal temperature to extend the service life of the mold.
