Improper control of resin gelation time

Resin gels too early or fails to gel for a long time during layup. This problem is relatively common in lamination molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) Temperature parameter aspect: ambient temperature fluctuation; temperature deviation directly affects the physicochemical state and reaction progress of the material. (2) Formulation control aspect: catalyst/curing agent metering deviation; component ratio deviating from the design value causes abnormal chemical reaction or physical state. (3) Process time aspect: resin system pot life not matching operation time; improper time control causes the reaction or cooling process to fail to meet process requirements, affecting the final performance of the product.

(1) Process control: control workshop temperature within a constant range; establish an online monitoring mechanism, set parameter upper and lower limits and implement alarm management. (2) Implementation measures: precisely meter catalyst/curing agent; formulate specific operation plans based on actual production conditions and verify implementation effects. (3) Material selection: choose resin systems with suitable pot life., establish material selection evaluation standards and determine the optimal solution through comparative tests. (4) Preventive measures: establish a sound 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.
