Optimization of Digital Simulation and Development Technologies for Plastic Molds and Process Upgrades

Release time:

2026-06-11

Traditional plastic mold development relies on manual experience, which suffers from insufficient prediction of molding defects, excessive trial times and cumbersome parameter debugging, making it difficult to adapt to the current production demands of multi-variety, small-batch and high-precision plastic parts. With the popularization of digital technology, the integrated CAD/CAE/CAM development mode has gradually become a universal industry standard, completely reconstructing the design and processing process of plastic molds. In the design stage, professional 3D modeling software is used to accurately build models of mold cavities, gating systems, cooling systems and exhaust systems. Professional mold flow analysis software simulates the whole process of plastic melt filling, pressure holding, cooling and solidification. Based on simulation data, common molding defects such as shrinkage, bubbles, warpage and weld lines can be predicted in advance. The position of gates, runner size and layout of cooling pipelines can be optimized to avoid production hidden dangers from the design source. Compared with traditional modes, digital simulation effectively reduces trial times, shortens the overall development cycle, and cuts down raw material and manual debugging costs. Meanwhile, digital parameters can be directly connected with CNC processing equipment, realizing seamless connection between design and production data, and ensuring mold processing accuracy and structural consistency. For new materials such as LCP, PEEK and long glass fiber modified plastics, digital simulation can accurately match material fluidity and shrinkage characteristics, customize and adjust mold structural parameters, meet the molding requirements of high-end precision plastic parts, and promote the transformation of plastic mold industry from empirical development to data-driven precise development.
