According to the customer's 3D product data and mold structure data in the early stage, the product production molding process parameter simulation is carried out to guide the product structure and mold structure design, provide practical injection molding parameters for mold production, improve production efficiency and reduce the number of debugging. At the same time, we will summarize and improve the mold flow analysis parameters in conjunction with the site, and provide a process report that is closer to the actual production.
