The primary goal of the mold test is to determine the optimal process parameters and modification scheme for a zinc alloy die casting mold. It is required that the zinc alloy die casting mold be capable of ensuring stable and uninterrupted mass production of qualified products, as well as maximizing the "adaptability" of the zinc alloy die casting supplier even if the material, machine setting, or environment, and other factors change. This is not just about getting a few good test samples.
Each and every one of the zinc alloy die casting molds produced by the zinc alloy die-casting factory aspires to be a zinc alloy die casting supplier with good "adaptability" (i. e., the ability to accommodate a wide range of molding parameters or process conditions). However, due to inadequate design considerations or inadequate processing during the manufacturing process, some problems, such as out of tolerance in size, unsmooth local transition, inappropriate structure, and so on, are frequently encountered, resulting in unqualified zinc alloy die castings or impossible trial production of zinc alloy die casting molds. The test mold is the most straightforward, direct, and effective method of determining the source of a zinc alloy die-casting mold problem.
One of the goals of a mold trial is to determine reasonable mold trial steps and to create appropriate records to ensure smooth production in the future. This is extremely important for the formal production in the future, which is why it is conducted in a controlled environment.
Process parameters for mold testing should be set so that the zinc alloy die-casting parts can be qualified and meet the technical requirements of customers as much as possible. This is to ensure that the zinc alloy die-casting mold and machine are protected from damage.
In the future, try to use the same alloy, die casting mold temperature, pouring temperature, and cooling time as you did in the past for mass production. These considerations will have a significant impact on the accuracy with which the size of zinc alloy die castings is determined. It is also critical to choose the proper die casting coating for the application.
Pouring temperature and amount of molten metal (thickness of residual cake) are important factors to consider.
With the above inspection, we can prevent the finished product from filling up the mold, shrinking, flashing, irritating the mucous membrane, and even damaging the zinc alloy die casting supplier. According to the results of the inspection, the process parameters are further tweaked in order to achieve the best die casting process conditions possible.
Dissect zinc alloy die castings and look for internal pores, shrinkage cavities, and other anomalous features.
Final point to emphasize is that the purpose and focus of the mold test is to optimize the zinc alloy die casting factory and process in order to meet the requirements of mass production, rather than simply testing several zinc alloy die-casting samples of zinc alloy die-casting.
