Mold trial is a crucial step in the mold manufacturing process, which aims to ensure that the mold can operate properly and produce products that meet the required standards. Before conducting the mold trial, it is necessary to clean and inspect the mold to ensure that all components are in normal condition without any damage or contamination.
During the mold trial, dry-run test is conducted first, which refers to checking the mold’s core, cavity, and gate without injection material. The main items checked include the mold’s dimensional accuracy, surface finish, fitting of various parts, and so on. Special attention should be paid to whether the mold’s core and cavity are normal, and whether there are any defects or damages. Any issues found should be adjusted and repaired in a timely manner to ensure that the mold can operate properly.
After completing the dry-run test, the next step is the wet-run test. The wet-run test refers to checking the mold’s various parameters during the injection process. The main items checked include the mold’s injection pressure, injection speed, injection temperature, and hot runner system, etc. By checking these parameters, the injection process of the mold can be ensured to meet the expected requirements, and the quality of the products produced can meet the quality standards.
During the mold trial, attention should also be paid to some details. For example, it is necessary to choose the appropriate injection material to ensure the accuracy and reliability of the trial. In addition, it is necessary to record the values and changes of various parameters during the trial process for subsequent analysis and improvement.
In summary, mold trial is an indispensable step in the mold manufacturing process. By conducting the trial, the quality and performance of the mold can be inspected, and the mold’s various parameters can be adjusted and optimized. Only through a strict mold trial process can the mold be ensured to operate properly and produce high-quality products.
