Injection Mold Gate Design

1 injection molding gate is a small opening between the runners and the mold cavity.

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. The mold itself consists of two faces between which is the cavity and core set into which the plastic is injected. Have a great influence on product appearance dimensional physical characteristics and production efficiency.

Plastic injection molding ring gate design 5. Plastic injection molding side gate design 6. 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 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.

Its shape is rectangle or semicircle and placed at side of the molded product. 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. This type is most generally adopted and used well in multi cavity mold. Their location quantity shape and size etc.

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. Consider how to hide the gate marks if they can not be removed. 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. Design guide for injection molding consider the gate for cosmetic parts and functionality like assembly.

For plastic injection mold design one of the most important factors is how and where the gate should be located. Below are some tips for injection mold gate design. It is the same side gate but gate have in front of products. 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.

2 the gate size is dependent on product weight material and gate types.
