Ten Wastes in Injection Molding
1. The structural design and processing of the injection mold are unreasonable, resulting in many times of mold testing and mold modification, and a large waste of materials, electricity, and labor;
2. Injection molded parts have many burrs at the gate and surrounding areas, resulting in a large amount of post processing, a large number of machine seats, and a large waste of labor;
3. Low awareness of the use, maintenance, and maintenance of injection molding tools, frequent mold failures and even damage during the production process, and frequent downtime and mold repairs resulting in waste;
4. Waste caused by poor use, maintenance, and maintenance of injection molding machines, shortened service life of injection molding machines, and downtime for machine repair;
5. The staffing of the injection molding workshop is unreasonable, the division of labor is unclear, responsibilities are unclear, and no one does what should be done, resulting in unsmooth injection molding production and waste;
6. Inadequate vocational skill training, low work ability, poor work quality, long machine adjustment time, and many problems resulting in waste;
7. The concept is backward, does not keep pace with the times, does not learn, does not progress, the injection molding technology management level is low, and the production efficiency in the injection molding production process is low, resulting in waste;
8. The control of the injection molding process is not in place, resulting in a large amount of scrap during production, a high defect rate, and a waste caused by batch returns;
9. The use of raw materials in mold testing and injection molding production exceeds the plan, and the machine nozzle material or rubber head is not strictly controlled, resulting in a large loss of plastic raw materials and waste;
"Improper injection molding production planning or machine scheduling, frequent mold rotation or machine replacement, resulting in" material "," labor ", and" cost "losses.".
The above ten major waste phenomena in injection molding should not occur, or can be well controlled, and can be improved and reduced through efforts. In fact, whether the injection molding workshop can make money or not, the most important thing is to find ways to control various wastes in the production process to achieve high-quality, efficient, and low consumption. In addition, mold warmers, chillers, shredders, mixers, dryers, and other injection molding auxiliary equipment are indispensable in injection molding production.
