No matter how well-maintained a mold is, it always require repair due to natural wear and tear.Especially plastic injection molding tools, which should be repaired or maintained after having a tight running for some time. However, prompt and precise repairs can significantly extend the tool's lifespan and ensure high quality of part. From the below several key issues to start.
When large defects parts appears in mass production, we may consider of mold damage, a thorough assessment should be conducted. We use precision measurement devices or non-destructive testing (NDT) methods like ultrasonic or dye penetrant testing to detect the core and cavities of the mold. Troubleshooting the problem of mold damage.
For minor cracks or surface damage, welding is a common repair technique. If neccessory Our skill-well technicians can use laser welding or TIG (Tungsten Inert Gas) welding to repair the damaged areas. After welding, re-machining or re-polishing may be necessary until the mold recovered completely.
After the mold has been used for a long time, some worn or damaged components such as ejector pins, guide bushings, or springs can be replaced by new ones. Resore the mold run smoothly and quickly, alignment and close and open action and minimizing production downtime.
In cases these wore components have degraded the mold’s performance, a full refurbishment procedure is started. This involves of disassembling the mold, inspecting all components, and repairing or replacing parts, the mold is then reassembled, re-polished, and tested until it can make qualified standard products.
Building a mold maintenance log or software system to track mold usage and performance. By using The effective way, and ensure timely maintenance and repairs. It includes the follow points.
Monitoring the number of cycles (injections) the mold, and recorded by the computer system. Depends on these cycle counts, can predict mold maintanence time. Some molds may require maintenance at interval few thousand cycles.
Tracking the number of defective parts produced by a mold, can highlight the mold performance and the reasons of defect parts . Also assess the value of the mold in mass production and loss and profit of enterprise.
