How to clean the molds in the injection molding factory before and after use, and how to maintain and upkeep the injection molds
In the field of injection molding, in order to ensure product processing quality, injection molding factories usually need to use high-quality molds, and the specifications and dimensions of these molds must meet the customer’s product needs. In addition, to ensure the normal use of the mold, it is also crucial to clean and maintain it properly. Next, let’s have Shenzhen Donglai Plastic Mold Manufacturer introduce how to clean molds before and after use:
1. Cleaning before use:
Mold is a key tool for producing injection molded products, which requires injecting raw materials into it for molding. If there are foreign objects or oil stains inside the mold, it will lead to a decrease in product quality. Therefore, in order to ensure product quality, injection molding factories should thoroughly clean the molds before using them, remove oil and rust from the mold surface, clean the cooling water holes, and ensure smooth water flow.
2. Cleaning during use:
During the use of the mold, the injection molding factory also needs to regularly clean the parting surface and exhaust groove of the mold, remove foreign objects, glue threads, and oil. In addition, the parting surface and runner surface should be cleaned twice a day to ensure the cleanliness of the mold and avoid affecting product quality due to foreign objects during use.
3. Cleaning after shutdown:
After a batch of products is processed, the injection molding factory needs to thoroughly clean the molds to avoid leaving production residues in them. Therefore, residual water in the mold should be promptly cleaned after shutdown to avoid residue of glue threads and foreign objects, and then rust inhibitor should be sprayed onto the mold after cleaning to prevent rusting.
Methods for cleaning molds at different stages in Shenzhen injection molding factories. Proper mold cleaning is crucial because the importance of molds cannot be replaced during the processing of injection molded products. Therefore, in order to ensure product quality, injection molding factories will pay special attention to the cleanliness of molds to avoid the presence of foreign objects and dirt in the molds, which can lead to a decrease in product quality.
