Sedimentation "hard bottom" of ceramic powder-filled casting material

After filler sedimentation, a hard deposit layer that is difficult to disperse forms at the bottom of the mold. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of material, process, and equipment.

(1) Material state aspect: High-density ceramic fillers settle rapidly and pack tightly in low-viscosity resin, Abnormal viscosity affects the flow filling and impregnation capability of the material. (2) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (3) Process aspect: Control deviation of key process parameters causes the '2079851475616104453 to deviate from optimal conditions. (4) Equipment aspect: Equipment precision and maintenance status affect the stable execution of process parameters.

(1) Formulation adjustment: Use nano-scale fillers to reduce the sedimentation rate, Adjust gradually and verify the effect, ensuring that other performance indicators of the product are not affected. (2) Formulation optimization: Add dispersants and anti-settling agents, Determine the optimal addition amount through small-batch tests, and verify the effect on the overall performance of the product. (3) Process operation: Stir fully before casting., Optimize stirring parameters to ensure uniform dispersion of all components, avoiding local concentration differences. (4) Preventive measure: Establish sound process control standards and a quality inspection system, and regularly review process data for continuous optimization.

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