TIPS
Plastic Mold Design & Manufacturing Insights
The design and manufacturing of plastic molds must begin with DFM (Design for Manufacturing) analysis, precisely matching material properties with mold steel selection¡ªfor instance, using P20 steel for ABS and H13 steel for PC. During the design phase, it is crucial to optimize the parting surface, gating system, and cooling channels, utilizing Moldflow analysis to predict defects like shrinkage and weld lines.
In manufacturing, strict control over CNC machining accuracy (¡À0.02mm) and EDM spark gaps (0.02-0.05mm) is required to ensure cavity roughness remains below Ra0.2¦Ìm. During trial runs, DOE (Design of Experiments) is used to adjust injection parameters, stabilizing the product's CPK above 1.33. The core lies in balancing precision, cost, and mass production efficiency, where every detail must account for both process feasibility and product performance.
