🔊 Grinding in the Lost Foam Shell Casting! Begin by gently blowing out debris with air below 100 degrees Celsius, while inspecting for any residual coating or debris along the sprue and vent edges. A tip: gently shaking the workpiece and listening for any internal sounds can help detect impurities. Once thoroughly cleaned, seal the shell in a plastic bag to prevent foreign matter from entering. And don't forget to seal any flow-out holes drilled during shell creation with refractory cloth for added protection. #LostFoamCasting #QualityControl #ManufacturingExcellence
