How Do You Operate and Maintain Plastic Injection Molds?

When compared with other tools, the plastic injection mold is more complicated and precise, with higher requirements for operation and maintenance. As a result, throughout the entire production process, their correct use and meticulous mold maintenance are of great significance to maintain the normal production and improve the efficiency of a company.

1. Select the right molding equipment, and determine the reasonable process conditions. If the injection molding machine is too small, it will not meet the requirements; if too large, it will waste resources. Also, it may damage the mold or the mold plate due to the improper adjustment of the clamping force, while at the same time affecting the production efficiency.

When selecting the injection molding machine, check the maximum injection volume, the effective distance of the tie rod, the mold installation dimensions on the plate, the maximum mold thickness, the minimum mold thickness, the plate stroke, the ejection type, the ejection stroke, the injection pressure, and the clamping force, etc. and choose the one that meets the requirements. The reasonable determination of the process conditions is also one of the factors that ensure the correct use of the mold. If the clamping force, the injection pressure, the injection speed and the mold temperature, etc. are set to be too high, the service life of the mold will be affected.

2. After installed with a mold, the injection molding machine must first be operated with the empty mold, to observe whether the operation of each part is smooth, whether there is any anomaly, whether the ejection and opening strokes are proper, whether the parting surface is tightly matched when the mold is closed, and whether the pressure plate screw is tightly fastened.
