After the injection mold is processed, the mold test is the last check step. Whether the mold can produce qualified products, you will know all about it. It can be said that the test model is a comprehensive test of our mold development and design, and the results of the test model will directly affect the production and quality of the factory products.
Why try the model?
Mold is a kind of precise instrument, and some problems in the production process are not found with the naked eye. And the precise tools need to be modified for several times to become qualified, and some small problems must be found and solved before production. In the process of manufacturing, there is very likely to be the phenomenon of insufficient storage and processing, so it is necessary to go through the test mold, and then analyze, evaluate and optimize according to the samples produced by the test mold, so as to meet the requirements of high quality. However, most of the defects of molding products are caused in the molding and injection stage, and may be caused by the improper manufacturing of plastic mold. Therefore, in order to avoid the product defects caused by the mold design, it is necessary to analyze the mold design and process parameters when making the mold.
What are the benefits of injection mold test mold?
Although the process parameters and mold design of injection mold can be optimized, the production cost of injection mold will also increase. If the structure of the injection mold is found to be unreasonable after the mold test, the injection mold needs to be improved, and this work will undoubtedly make the injection cost over the budget. For example, some injection mold design is very good, but there is a process is not in place, when the test mold did not choose the best molding process and injection mold, it is obvious that the mold is very good, but in the injection molding after the product is not good. There is also a complete understanding of the physical properties of plastic, no accurate shrinkage rate, which often happens. Let people vomit blood is, many cases are not satisfactory, even the injection mold should be scrapped again.
Prepare for the trial model at the best.
1. Understand the injection molding products
Engineers need to understand the shape and structure of the product in advance, the structure and characteristics of the product, so that they can quickly find and solve the mold test.
2. Prepare drawings
Before T1, the mold test drawings should be prepared. If no customer provides the drawings, the manufacturer needs to mark the length and width of the caliper according to the 3D of the product, at least 2 sizes, easy to be adjusted during mold test.
3. Prepare measuring tools
According to the size of the drawing, prepare suitable measuring tools, or measuring tools, and match samples to facilitate measurement and verification.
4, familiar with the raw material properties and processing conditions
The project needs to be familiar with the physical properties of the raw material, and can judge whether the forming conditions are in a reasonable range on the spot.
5. Issue the trial trial notice
According to the characteristic size of the product weight mold and the conventional requirements of the mold, the project will issue the mold test sheet to facilitate the arrangement of the suitable machine. The mold test sheet needs to mark the water connection method and requirements, and the priority is preferred according to Mold Flow conditions.
6. Determine the equipment
It is also necessary to confirm whether the auxiliary equipment, such as the number of water pipes required by the mold, the number and performance of water interfaces and other basic hardware facilities can meet the requirements of the mold test, and to prepare a thermometer.
7. Notify the relevant participants
Before mold test, quality personnel should be notified to participate, while for important molds, mold projects, product projects, fitter and designers should be notified to participate. If the problems in the mold reach the technical bottleneck of the company, all departments will discuss the plan on site.
