Surface Flow Marks/Ripples

Obvious flow marks or ripple-like defects appear on the product surface. Surface defects directly affect the appearance quality and use performance of the product, and are particularly obvious in transparent products. This defect affects the appearance quality of the product and reduces the market competitiveness of the product.

(1) In terms of process speed: the flow rate of the casting liquid on the mold surface is unstable, speed parameters affect the synchronization of material flow state and reaction progress. (2) In terms of temperature parameters: the mold temperature is too low, causing the flow front to gel prematurely, leading to insufficient reaction kinetics or deterioration of material fluidity, affecting the normal progress of the '2079851475616104453. (3) In terms of process speed: interruption or speed fluctuations during casting, speed parameters affect the synchronization of material flow state and reaction progress.

(1) Parameter adjustment: increase the mold temperature, it is recommended that each adjustment amplitude be 5-10℃, while monitoring product quality changes to avoid new defects caused by excessive temperature. (2) Parameter adjustment: increase the casting temperature to improve fluidity, it is recommended that each adjustment amplitude be 5-10℃, while monitoring product quality changes to avoid new defects caused by excessive temperature. (3) Implementation measures: maintain continuous and stable casting, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (4) Implementation measures: adopt inclined casting to make the liquid level rise steadily., formulate a specific operation plan based on actual production conditions and verify the implementation effect. (5) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.

Surface defects are the result of the combined effects of mold condition, process parameters, and material formula, and each factor needs to be systematically investigated and optimized in a targeted manner.
