The casting material swells the release agent

The release agent is swelled by the solvent or active components in the casting liquid and fails. This problem is particularly prominent when the production cycle is fast or the mold temperature is abnormal, and in severe cases causes product damage.

(1) Process factor: The chemical structure of the release agent does not match the casting liquid solvent, This factor affects the '2079851475616104453 and final quality of the product. (2) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (3) Process aspect: Control deviation of key process parameters causes the '2079851475616104453 to deviate from optimal conditions. (4) Equipment aspect: Equipment precision and maintenance status affect the stable execution of process parameters.

(1) Material selection: Select solvent-resistant release agents (such as perfluoropolyethers), Establish material selection evaluation criteria, and determine the optimal solution through comparative tests. (2) Implementation measure: Confirm the chemical stability of the release agent before casting., Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (3) Process optimization: Determine the optimal process parameter window through systematic tests and establish standardized operating procedures. (4) Quality control: Strengthen process monitoring and product inspection, Establish a defect early-warning and traceability mechanism. (5) Preventive measure: Develop a mold maintenance plan and regularly check the release agent coating and mold surface condition.

The demolding problem needs to be solved comprehensively from three aspects: mold surface treatment, release agent selection, and curing degree control.
