The manufacturing cost of the mold is not low, and in the production process, the mold will be used repeatedly, and it will inevitably be damaged in the long run. It needs to be repaired or replaced in time, so as not to affect the next use and affect the delivery time. The following professional mold manufacturers will tell you how to reduce the number of mold repairs and improve the efficiency of mold production?
1. How to reduce the number of mold repairs
1. Regular maintenance of the mold
Molds, like injection molding machines, must be maintained regularly. Mold injection molding is a relatively expensive processing technology. Regular maintenance of molds is conducive to reducing costs. It is best to choose mold manufacturers that have a complete maintenance system process and check regularly. The wear of each mold, whether there is dust or wire drawing, if it is found that the thimble is stuck, the spring is broken, or the shovel is punctured, it must be repaired in time. Usually pay attention to the primary and secondary maintenance of production. When the mold fails, ask the mold repair department to do the tertiary maintenance.
2. Pay attention to mold damage during production
Many mold damages are caused in the production process. For example, in the production process, sometimes the ejector pin is stuck in the mold, and the hot runner is blocked by iron. Therefore, the skilled workers of mold manufacturers must undergo professional training to avoid mold damage and reduce costs during mold production.
3. Adopt standardized process for production
Irregular and inappropriate mold production processes will lead to increased damage or frequency of molds, and even equipment failures such as injection molding machines. Damaged molds and equipment failures not only affect costs, but can also lead to late deliveries. Therefore, performance appraisal and standardized training of technical personnel should be carried out!
4. Design and manufacture faults that meet the standards
If the fault of the mold is caused by the "feet", then it will be difficult to avoid a lot of failures and problems in the later stage. Therefore, when designing and manufacturing the mold, the mold manufacturer must abide by the design standards of the seven major systems of the mold and the selection of materials for the mold making. It must also be suitable.
5. Sufficient inventory should be prepared for vulnerable parts
In addition to the "front hand" just in case, it is also necessary to keep the "back hand". For the parts that are easily damaged in the mold - such as springs, thimbles, guide sleeves, cylinders, guide posts, etc., it is best to do To a unified specification, it is convenient to prepare enough inventory, and if there is a fault, the damaged parts can be replaced in time to avoid delays in production.
6. Strengthen the training of technical personnel
Technicians of mold manufacturers should understand and master the most basic knowledge of injection molding, including low pressure protection settings, injection speed, mold clamping speed, holding pressure, clamping force, mold temperature and other important parameters, and try to avoid damage to the mold during production operations.
Second, the service life of the injection mold
In order to reduce cost losses, manufacturers are more inclined to use injection molds with long service life. Generally speaking, the service life of a qualified injection mold is 300,000 times, and a full set of maintenance is required for every 50,000 times of use. Other faults that occur during the production cycle can be solved by replacing parts. But in fact, the work of mold repair is far from being so simple, and mold repair in reality is more frequent and complicated.
