1. Lógica Central: Process & Mold Optimization Based on Standard Troubleshooting
Precise Tuning of Injection Parameters
Process optimization is the primary solution to sink marks. Priority should be given to optimizing packing settings with multi-stage packing technology:
Apply high pressure (90% of filling pressure) for the initial 2–3 seconds for rapid shrinkage compensation, then reduce pressure to 60% and hold until gate solidification.
Moderately raise mold temperature (10–20℃) and melt temperature (5–10℃) to lower melt viscosity, delay skin layer solidification and reserve sufficient time for internal feeding.
Além disso, adopt slow injection speed (≤50 mm/s) over thick-wall zones to build a favorable temperature gradient for shrinkage compensation.
Improvement of Mold Structure & Projeto
If parameter adjustment fails, mold design must be reviewed:
Place gates as close as possible to thick-wall sections and enlarge gate cross-section to extend the feeding channel. Optimize cooling circuit layout with conformal cooling channels or beryllium copper inserts. Keep mold temperature difference between thick and thin wall areas within 5℃ to avoid aggravated shrinkage deviation caused by uneven cooling.
