Warpage deformation means that the shape of injection molded products is deformed and warped unevenly, which deviates from the shape accuracy requirements of the parts. It is one of the common and difficult product defects in injection mold design and injection production. With the development of th... read more
After more than half a century of development, my country's mold industry has been greatly improved, and the development speed is very rapid. In general, the development of mold design and manufacturing technology in China has gone through the embryonic stage of handcrafted workshop manufacturing, t... read more
There are two main purposes for polishing precision stamping dies. One is to increase the brightness and beauty of the precision dies. The second is to make the mold easy to demold. When polishing, generally use a coarse whetstone to roughen the surface of the machined mold cavity, and then grind aw... read more
The working failure of the stamping die is closely related to the resistance to congestion.The durability of the stamping die.After working for a period of time, the working size is lost due to frequent wear and tear, and the technical conditions of the parts can no longer be met. According to the t... read more
In order to let the plastic mold be damaged or abnormal after injection molding, we need to perform certain specifications on the mold injection molding, and its main requirements meet the following six conditions: 1. Turn off the mold pressure: in principle, it should be greater than the total pres... read more
