Latest Patents

Kumazaki holds a patent for a blow molding method, blow molded product, and blow molding mold. This patent focuses on blow-molding molds that incorporate parison shutters to prevent the inflation of the parison toward the outside of the molds. The design creates a closed space that secures a predetermined air within the parison during the frame clamping step. As the pressure inside the parison increases during the mold clamping step, the parison maintains contact with the die design surface. This innovative approach allows for uniform contraction through cooling, thereby avoiding molding failures such as streaks and uneven pattern transfers. The result is a blow-molded product with an aesthetically pleasing appearance.
