Six advantages of mold blow molding

(1) When the melt is injected into the mold cavity of the parison, it undergoes a certain orientation effect in the circumferential direction. In addition, the temperature of the parison during inflation is lower than that of extrusion blow molding, and the orientation effect produced by inflation can be more retained, which helps to improve the strength and other properties of the container.

(2) High accuracy of container size (especially neck thread size): it is easier to ensure the uniformity of container wall thickness according to requirements, and container specifications are uniform.

(3) There is no joint seam formed on the container, no trimming is required, and no leftover material is generally produced (the leftover material produced by extrusion blow molding is usually 5% to 30%).

(4) A sliding bottom module can be set on the blow mold, so the design flexibility of the bottom shape of the container is greater.

(5) It is more suitable for forming rigid plastic containers and wide-mouth containers.

(6) The glossiness of the container is high, and the container molded with transparent polymer is always transparent.
