During the production process of the rain shoe machine, the size of the rain shoes produced may be unstable and have surface defects due to various reasons. How should we adjust it? Due to the unstable pressure of the shoe machine, high or low injection pressure can affect the dimensional accuracy of slippers. At the same time, uneven mold temperature can also cause uneven shrinkage of rain shoes during the molding process, thereby affecting dimensional stability. To address this issue, we can use pressure sensors or pressure gauges to monitor and adjust to ensure that the mechanical operating pressure is stable within an appropriate range.

Heating rods, electric coils, etc. can also be used to adjust the temperature of the mold to ensure uniform temperature. Surface defects on rain boots may be caused by scratches or dirt on the mold surface that have not been cleaned thoroughly during the production process, or by improper mechanical process parameter settings such as excessive injection speed, high pressure, and long holding time, which can all lead to surface defects on the slippers.

Impurities in the raw materials used can form defects such as black spots and bubbles on the surface of slippers. Specifically, we can inspect the surface of the mold before production. If there are scratches or dirt, they can be repaired or cleaned in a timely manner. Tools such as sandpaper and polishing agents can be used to repair the mold, or cleaning agents can be used to clean the mold. Suitable injection molding speed, pressure, and holding time can also be set according to different material and process requirements. You can conduct a trial mold and gradually adjust the parameters until the best molding effect is achieved.

To check the quality of raw materials, tools such as filters and sieves can be used to filter the raw materials, or qualified raw materials can be replaced. In short, when using the rain shoe machine, regular maintenance and upkeep should be carried out to promptly detect and eliminate faults, in order to ensure the normal operation of the machine and the quality of the slippers. If encountering unsolvable faults, professional maintenance personnel should be contacted in a timely manner for repair.
