Skin too thick

The thickness of the dense skin layer of foam products exceeds the standard. This problem is relatively common in foam molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) Temperature parameter aspect: mold temperature too low causing rapid surface cooling to form a thick skin, leading to insufficient reaction kinetics or deterioration of material fluidity, affecting the normal progress of the '2079851475616104453. (2) Pressure parameter aspect: foaming pressure insufficient to fully "blow thin" the skin, causing the material to fail to fill fully or insufficient densification, resulting in decreased product density and bonding strength. (3) Material aspect: fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (4) Process aspect: control deviations of key process parameters cause the '2079851475616104453 to deviate from optimal conditions. (5) Equipment aspect: equipment precision and maintenance status affect the stable execution of process parameters.

(1) Parameter adjustment: increase mold temperature; it is recommended that each adjustment range be 5-10°C, while monitoring product quality changes to avoid new defects caused by excessive temperature. (2) Parameter adjustment: increase foaming agent dosage or increase foaming temperature; it is recommended that each adjustment range be 5-10°C, while monitoring product quality changes to avoid new defects caused by excessive temperature. (3) Formulation adjustment: reduce the surface cooling rate., adjust gradually and verify the effect, ensuring that other performance indicators of the product are not affected. (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.
