Mold flow analysis
A specialized technology that uses computer simulation software to model the entire process of plastic filling, holding pressure, and cooling within a mold, thereby predicting and optimizing injection molding processes.
Material: PVC Molding method: Two-point hot runner system with bullnose sprue Filling time: 2.624 s Maximum pressure: 44.34 MPa Mold flow analysis ensures balanced flow, and the weld line is located in an inconspicuous corner area.
Material: ABS Molding method: 3-point hot runner Filling time: 1.076 s Maximum pressure: 35.04 MPa
Molded Part: Automotive Mudguard 1 Plastic Material: TPE System: 25VE Description: Two-point needle valve gating with cold runner system. Precautions Before Mold Opening: 1. Accurately identify the gate locations through mold flow analysis. 2. Determine the appropriate sizes for runners and gates. 3. Carefully calculate the positions of weld lines and venting points. 4. Ensure balanced control of melt flow at the hot runner outlets. Through mold flow analysis, adjust the sizes of runners and gates: 1. Achieve precise control over the amount of material injected. 2. Prevent excess material from accumulating at the interface between the molded part and the sealing strip. 3. By precisely controlling temperature, injection time, and material volume, ensure that the joint area remains firmly bonded and is less likely to detach.
