The modification principle and method of injection mold

The injection mold needs to be modified under the following circumstances, that is, the modification principle of the injection mold: 1. Wear and tear of mold parts in normal production; 2. Crash caused by abnormal production; 3. Plastic debris crushed mold parts. Design errors, processing errors or product design changes in the injection mold factory require design changes;

The main repair methods of injection mold include repair welding, line cutting, partial discharge iron reduction material, overall iron reduction material and replacement parts.

Injection mold repair welding: parts need to add iron material, laser welding, or fluorine arc welding iron material on. The welding head can be extended into, or the electrode can be extended into the place where it will not meet the other places of the mold. The repair welding area can not be too large and the place where the force is often stressed is recommended not to repair welding.


Injection mold line cutting: Through the line cutting machine, cut a piece of iron from the mold to make a insert to assemble on the injection mold. Parting lines are allowed on the surface of the product, and there is no water air path on the mold.

Injection mold partial discharge iron reducer: injection mold only need to reduce the iron to meet the requirements of the place, can be used in almost any situation.

Injection mold overall iron reduction material: the mold, into the child, inclined pin, slider, thimble all processing to remove a part of the iron material. When the overall size of the product is out of tolerance and the mold surface pattern is changed, the overall iron reduction material is needed. At the same time, the gap of iron reduction material needs to be left on the template, otherwise the template also needs iron reduction material.


If the main parts of the injection mold are seriously damaged, the maintenance cost exceeds the actual output, the injection mold has reached the design life cycle or the product is no longer produced, the mold needs to be scrapped. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
