Rainbow patterns/interference colors appear on the product

The surface of transparent products shows rainbow-like interference colors. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of material, process, and equipment.

(1) Process factor: Micron-level thickness deviations on the product surface form thin-film interference, This factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: The release agent is applied with uneven thickness, This factor affects the '2079851475616104453 and final quality of the product. (3) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (4) Process aspect: Control deviation of key process parameters causes the '2079851475616104453 to deviate from optimal conditions. (5) Equipment aspect: Equipment precision and maintenance status affect the stable execution of process parameters.

(1) Implementation measure: Improve the flatness and finish of the mold surface, Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (2) Formulation adjustment: Reduce the amount of release agent used, Adjust gradually and verify the effect, ensuring that other performance indicators of the product are not affected. (3) Implementation measure: Adopt self-lubricating mold materials., Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (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.
