Increase packing pressure/time and optimize rib thickness (≤60% of main wall thickness).

Likely due to unbalanced runners or uneven cooling. Optimize the gating system.

Implement modular design, 3D-printed prototypes, and concurrent engineering.

Check draft angle (≥1°), ejector pin layout, and mold surface polish (Ra≤0.2 recommended).

Apply anti-rust coatings, clean regularly, and control cooling water pH (6.5-7.5 recommended).

Determine optimal position via mold flow simulation based on product structure, wall thickness, and aesthetics to minimize weld lines.

Increase venting slot depth (0.02-0.04mm) or use porous steel. Ensure vents are unblocked.

Check mold machining accuracy, cooling system consistency, and material shrinkage. Use mold flow analysis for optimization.

Flash is caused by worn parting surfaces or excessive injection pressure. Repair mold gaps and adjust clamping force.

Mold lifespan is affected by material selection, heat treatment, maintenance frequency, and injection parameters. Use high-hardness steel, perform regular maintenance, and optimize pressure/temperature.
