Injection mold gate design.

Gate locations or multi gates will cause weld lines. The purpose is to make the gate position of the mold consistent with the center of the mold to avoid the gate offset of the mold. Have a great influence on product appearance dimensional physical characteristics and production efficiency. Plastic injection molding side gate design 6.

1 injection molding gate is a small opening between the runners and the mold cavity. Gate is a passage way from the subrunner to the mold cavity and its cross section is the smallest and shortest part in the injection system. Design guide for injection molding consider the gate for cosmetic parts and functionality like assembly. The mold itself consists of two faces between which is the cavity and core set into which the plastic is injected.

Below are some tips for injection mold gate design. Position number shape and size of the gate have a direct impact on the quality and the appearance of the product and therefore in the design process attention is required for gate style. Its shape is rectangle or semicircle and placed at side of the molded product. For plastic injection mold design one of the most important factors is how and where the gate should be located.

2 the gate size is dependent on product weight material and gate types. The importance of gate design and gate size in injection molding while injection molds tools are hard to design and manufacture their core concepts are easy to understand. Injection mold gate design essentials of a well designed injection mold gate a properly injection mold gate design will deliver a rapid uniform and preferably uni directional mold filling pattern with a proper gate freeze off time. Since the curved core is subjected to the injection force the core is pushed to the opposite side so that the pipe cannot be molding.

Gate type design and location can have effects on the part such as part packing gate removal or vestige cosmetic appearance of the part and part dimensions warping. Each injection mold design must have a gate or an opening that allows the molten plastic to be injected into the cavity of the mold. But the test results show that. Consider how to hide the gate marks if they can not be removed.
