Gelled particles (gel particles/fisheyes)

Unmelted resin granular defects appear in the product. 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: During resin storage or transportation, partial pre-polymerization forms micro-gel particles, This factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: Or poor compatibility of formulation components causes local precipitation, 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: Filter the casting liquid with a fine-mesh screen before casting, Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (2) Equipment maintenance: Check raw material storage conditions and shelf life, Develop regular inspection and maintenance plans to ensure the equipment is in optimal working condition. (3) Implementation measure: Scrap the problematic raw material batch., 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.
