When producing zinc alloy die-castings, new product development and updates to existing molds are frequently encountered in production. In general, the internal and external quality of zinc alloy die-casting parts is dependent on die-casting production process parameters such as the temperature of the molten metal, the pressure of the die-casting process, the speed of the process, and the point at which the speed switches. Molds used for zinc alloy die-casting are affected by a number of factors, including the structure of the zinc alloy die-casting part itself, the number of cavities in the mold, the design of the pouring system, and the type of gate.



It is necessary to conduct tests on zinc alloy die casting molds after they have been completed in order to inspect and address any issues that may have arisen during the production of zinc alloy die casting molds, as well as to prevent defects in zinc alloy die cast parts that could have been caused by the design of zinc alloy die-casting molds.It is necessary to be able to ensure zinc castings that zinc alloy die casting molds can be produced in batches in a stable and uninterrupted manner even if factors such as the materials, machine settings, or environment change.Not only should you try to get a few good trial mold samples, but you should also produce qualified products and maximize the adaptability of zinc alloy die casting molds.1Find out what the issues are with die-casting molds made of zinc alloy.
The zinc alloy die-casting molds that are manufactured at the zinc alloy die-casting factory all have the same goal in mind: to create a zinc alloy die-casting mold that has a high level of adaptability. This ultimately leads to the production of zinc alloy die-castings that do not meet the required standards.It is not possible to carry out the trial production of molds for alloy die-casting.2Find the optimal conditions for formation.
During the process of mold trial, the personnel responsible for mold trial can find a set of the most suitable process data. This set of data can then be used as the default value for setting machine parameters during mass production. Additionally, the batch size of the zinc alloy die-casting mold can be adjusted based on this set of data.conditions of the process that are ideal for production.3Confirm the design that was assisted by CAE, and then improve subsequent work efficiency
The CAE analysis software is the product of computer simulations and calculations that are based on the parameters of actual machines, the characteristics of actual alloys, and the actual conditions of the surrounding environment.During the actual machine mold trial, the analysis data can be directly input as a preset value, and the mold tester can use this to check and analyze the zinc alloy die-casting mold. Zinc alloy die-casting mold designers are able to make corresponding corrections to the zinc alloy die-casting mold design based on the simulation situation.Is there anything wrong with the way the mold for the die-casting was designed?In order to provide a foundation for the subsequent process parameter settings, the flaws of the test module can be compared and analyzed alongside the results of the simulation.

2.1 Determine the appropriate steps for the mold trial
One of the purposes of mold trial is to determine reasonable mold trial steps and make appropriate records for smooth future production, which is of great significance to future formal production. In addition, one of the purposes of mold trial is to determine reasonable mold trial steps.

2. In particular, it is essential to remember that the model of the die-casting machine that will be used for the mass production of the mold must match the model of the die-casting machine that will be used for the trial molding.

3. Parameters and adjustments of the trial mold process that have an effect on the quality of zinc alloy die-casting parts
3.1 General guidelines for determining the values of process parameters
When setting process parameters for the trial mold, the zinc liquid temperature, injection speed, pressure, and any other parameters should be as low as possible to protect the zinc alloy die-casting mold and machine. This is true so long as the zinc alloy die-casting parts can be qualified and meet the technical requirements of the customer.

3. The correct determination of the size of zinc alloy Plating die-casting parts will be significantly impacted by the aforementioned factors. It is also essential to select the appropriate coating for the die-casting process.

After the design of the zinc alloy die has been completed, the fast injection stroke can be calculated; in most cases, the calculated and actual strokes are not very different from one another. The determination of the position of the fast injection conversion can be finished in the following manner: first, the injection end position is moved back a certain distance; second, a small amount of forward and backward adjustments are made according to the production conditions of zinc alloy die castings; and finally, the fast injection conversion position is determined. During the mold trial process, when adjusting parameters, generally only one parameter is adjusted at a time in order to distinguish the impact that a single parameter change has on the quality of zinc alloy die castings. This is done in order to determine which parameters have the greatest impact on the quality of the zinc alloy die castings.


Mold testing, also known as a mold trial, is an actual inspection process that is done before using mold. Base.

Patient and careful work is required in order to solve the myriad of problems that crop up in the trial mold. You are not allowed to make arbitrary changes to the zinc alloy die-casting mold. to prevent the incurring of unnecessary losses. In conclusion, it is essential to emphasize that the purpose of the mold trial, in addition to testing out a few zinc alloy die casting samples, is to optimize the zinc alloy die casting mold and process in order to meet the requirements of mass production. This should be the primary focus of the mold trial.
