Improper Control of Casting Gelation

The cast film gels too fast or too slow on the carrier. 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 temperature parameters: unreasonable temperature settings for each section of the casting machine, temperature deviation directly affects the physicochemical state of the material and the reaction progress. (2) In terms of process speed: the gelation speed in the liquid formula is too fast or too slow, speed parameters affect the synchronization of material flow state and reaction progress. (3) In terms of process speed: the carrier belt speed does not match the gelation speed, speed parameters affect the synchronization of material flow state and reaction progress.

(1) Design optimization: optimize the temperature gradient settings of each section of the casting machine, combine process simulation analysis or trial mold verification to continuously iterate and improve the design plan. (2) Implementation measures: adjust the amount of gelation accelerator in the formula, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (3) Implementation measures: coordinate the carrier belt speed with the gelation time., 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.
