Insufficient Casting/Incomplete Filling

The far end of the mold cavity is not filled, and the product lacks material. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) In terms of material state: the viscosity of the casting liquid is too high and the fluidity is insufficient, abnormal viscosity affects the material's flow filling and impregnation capabilities. (2) Process factors: improper gate position or runner design, this factor affects the product's '2079851475616104453 and final quality. (3) In terms of process speed: too slow a casting speed causes the solidification front to gel prematurely, speed parameters affect the synchronization of material flow state and reaction progress.

(1) Parameter adjustment: appropriately increase the casting temperature to reduce viscosity, it is recommended that each adjustment amplitude be 5-10℃, while monitoring product quality changes to avoid new defects caused by excessive temperature. (2) Design optimization: optimize the gate and vent channel design, combine process simulation analysis or trial mold verification to continuously iterate and improve the design plan. (3) Formula optimization: increase the casting pressure or adopt pressure-assisted casting., determine the optimal addition amount through small-batch tests and verify its impact on the comprehensive performance of the product. (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.
