Uneven Wall Thickness of Slush-Molded Products

Slush-molded products are locally too thin or too thick, and even holes appear. 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 process time: improper coordination of mold rotation speed and time, improper time control causes the reaction or cooling process to fail to meet process requirements, affecting the final performance of the product. (2) In terms of process time: unstable liquid viscosity or gelation time, improper time control causes the reaction or cooling process to fail to meet process requirements, affecting the final performance of the product. (3) In terms of temperature parameters: uneven local mold temperature, temperature deviation directly affects the physicochemical state of the material and the reaction progress.

(1) Design optimization: optimize the rotation program (speed, angle, time), combine process simulation analysis or trial mold verification to continuously iterate and improve the design plan. (2) Implementation measures: stabilize the liquid viscosity and gelation time, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (3) Implementation measures: ensure uniform mold heating., formulate a specific operation plan based on actual production conditions and verify the implementation effect. (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.
