Skin too thin

The product skin has insufficient strength and is easily damaged. 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 high causing excessive foaming of the surface layer, which may trigger thermal degradation of the material or runaway reaction rate, damaging the internal structure of the product. (2) Process factor: or the skin is not fully cured at demolding; 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 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: appropriately lower the mold temperature, noting that after cooling it is still necessary to ensure the material fully reacts or melts; adjust step by step and observe the effect. (2) Process optimization: extend in-mold curing time; determine a reasonable time based on product wall thickness and material characteristics, balancing production efficiency and quality. (3) Implementation measures: adjust the foaming formulation so that the foaming speed in the surface area is slightly slower., formulate specific operation plans based on actual production conditions and verify implementation effects. (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.
