What factors in injection molding processing are related to production costs

The relationship between injection cycle time and production cost. Under the premise of ensuring product quality, the shorter the injection cycle time, the better, so that the more the production quantity, the lower the manufacturing cost of the unit product. What are the elements of the injection cycle time: injection time, pressure holding time, cooling time, mold opening time, ejection time. The most important methods to shorten the injection cycle time: reduce the wall thickness of the plastic part/runner size, reduce the opening and closing distance/thimble stroke, quickly take out the product, manipulator operation, speed up the opening/closing of the safety door, and reduce the stickiness of the plastic parts. Mold phenomenon, correct selection of cooling time, reasonable setting of mold opening/closing speed and ejector speed/number of times, etc. To shorten the injection cycle time is to improve production efficiency.

The relationship between mold maintenance and production costs. If mold maintenance is not done in place, mold failures will often occur during the production process, and frequent production stops will be required for maintenance. This will affect the smooth progress of production and the stability of the quality of rubber parts, and will cause economic losses to the enterprise. For example, mold repair costs, plastic raw materials/power consumption, labor costs, and machine shutdown losses. Therefore, we need to carry out proper maintenance work on production tools such as molds. To ensure that the production process will not drop the chain, malfunction, etc. After the mold maintenance is in place, a series of problems will not occur later, and the smooth production will be guaranteed. Mold maintenance is urgent, it is an important guarantee for production.

In addition, there is the relationship between quality and production cost. "Product quality is the life of an enterprise." The return of plastic parts and the high defect rate are the biggest waste. The reputation of the company is affected, and it also causes great economic losses to the company. If the product quality control in injection molding production is not good, there will be high defect rates, many scraps, low output, return and rework, delayed delivery, and even loss of customer orders, and the competitiveness of the company will decline. These are things we don't want to see. If there is a batch return in the injection molding process, the loss will be even greater. Quality is something we cannot take lightly. Only good quality can have a good reputation. With a good reputation, customers will naturally believe in you, and of course orders will continue to come.
