Mold cleaning is a key process in the maintenance and upkeep of injection molds, and it is also a bottleneck that restricts mold maintenance. Because the speed of mold manufacturing and development is much faster than the speed of mold cleaning, and the mold needs to be prepared for the next production immediately after rapid cleaning, the time left for mold cleaning is quite limited.

When cleaning and repairing molds, some factories hire junior technicians or apprentices from the mold workshop to do miscellaneous tasks such as cleaning molds and templates. Subsequently, maintenance technicians split the molds and templates. However, in fact, cleaning the mold and template also washes out the magnetic track marks, which poses difficulties for maintenance technicians to discover and correctly repair defects in the mold and parts.

Indeed, cleaning molds does not require the skills of advanced mold making technicians, but it is a completely thoughtless decision to have a novice who is not familiar with the special functions and defects of the mold or is not familiar with the characteristics of the key sealing areas of the mold responsible for mold cleaning. The unreasonable allocation of mold cleaning work will lead to the continuous production of molds with performance defects, and the addition of seams, burrs, corners, premature electroplating or steel displacement, and mold mixing will also significantly increase the budget of the mold. This type of problem often originates from a "temporary firefighting" maintenance culture, where defects are not monitored or accounted for and the root cause of the problem is identified.

Standardized cleaning procedures

Systematic mold maintenance is based on the continuity of maintenance needs and repair operations. In order to achieve the goal of "cost effectiveness", it is necessary to pay attention to the development of a detailed mold cleaning plan when cleaning molds. When cleaning different parts of the mold, such as internal cleaning of the press, edge wiping, routine cleaning, and main part cleaning, the cleaning methods used are also different.

After a certain period of mold operation and visual testing of electroplating wear, magnetic track markings, and residual content in the vent and non vent areas of the mold, technical personnel can determine the procedure and frequency of mold cleaning through visual inspection. Therefore, it is very important to understand the safe operation cycle of the mold and archive observation reports on the accumulation of residual materials and wear inside the mold.

How to clean the injection mold properly during maintenance and upkeep?

Based on the fact that molds have a certain operating cycle, all molds should be accompanied by relevant maintenance procedures and documented maintenance cycles.
