Improper Gate/Runner Design

Jetting, air entrapment, or flow imbalance occurs during the casting filling process. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) Process factors: the gate cross-section is too small, causing jet filling, this factor affects the product's '2079851475616104453 and final quality. (2) Process factors: drastic changes in runner cross-section produce turbulence, this factor affects the product's '2079851475616104453 and final quality. (3) Process factors: unreasonable multi-gate layout causes weld lines, this factor affects the product's '2079851475616104453 and final quality.

(1) Design optimization: optimize the gate size and position to ensure laminar filling, combine process simulation analysis or trial mold verification to continuously iterate and improve the design plan. (2) Formula adjustment: adopt fan-shaped or film gates to reduce shear, adjust gradually and verify the effect, ensuring that other performance indicators of the product are not affected. (3) Design optimization: optimize the runner design through mold flow analysis., combine process simulation analysis or trial mold verification to continuously iterate and improve the design plan. (4) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.

This problem requires comprehensive analysis from multiple dimensions of materials, processes, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
