1.The quality of die steel is unstable
Die steel has many quality problems and unstable quality. The same type of forging has good performance for a period of time and poor performance for a period of time. Frequent replacement of Injection Molds by enterprises has also caused problems for enterprises to improve production efficiency.
2. Design aspect of outer contour of forming die
In terms of lean production, the common height of the forming Injection Molds of Japanese Injection Moldcompanies is relatively small. The reduction in the size of the Injection Moldis guaranteed by a special process, such as the high flatness of the Injection Mold contact surface of the Injection Mold base, the related equipment conditions and the level of the operator. Significantly reduce the height of the Injection Mold, it is currently difficult to implement in domestic forging companies.
3. Use of Injection Mold lubricant
For the production of different types of parts, the choice of lubricants varies greatly. For example, when producing parts with complex shapes, poor lubricant selection can lead to problems such as filling the Injection Mold cavity and reducing the life of the Injection Mold. At present, there are few brands and types of domestic forging die lubricants that can be selected.
4. Insufficient Injection Mold evaluation methods
Foreign counterparts pay more attention to detailed analysis and research, such as simulation of Injection Mold usage, analysis of test data during the whole forging process, methods of evaluating lubricant performance tests, and simulation prediction of Injection Mold life.
5. Improper use of Injection Mold
The use and maintenance aspects related to the life of the Injection Mold are: the installation accuracy of the Injection Mold, the type of equipment and its accuracy, the lubrication and cooling conditions, the preheating temperature and its uniformity, the standardization of the operation, the cleaning of scales and dirt, the storage method and The environment and maintenance, etc.
