Injection Mold Fan Gate Design

Plastic injection molding fan gate design.

Injection mold fan gate design.

It permits rapid filling of large parts or fragile section mold area with large entry area. It is used to create uniform flow into wide parts. But the test results show that. Thereby keeping the cross sectional area constant.

Fan or edge gate a common gate located in the sidewll of the part to prevent restriction of resin flow. Molded part in the mold which is now loaded in the center. This is only possible how ever for certain materials such as thermoplastic elastomers. Fan gate is a gate spreading toward in to cavity basically this gate is thin similarly with previous gate and is used in same purpose with film gate.

Ring part must get filled first and then the cylinder part otherwise the weld will occur. 2 the gate size is dependent on product weight material and gate types. It has the following advantages. Have a great influence on product appearance dimensional physical characteristics and production efficiency.

Used in large size molded product. Plastic injection molding tab gate design 3. Normally used with thin wall parts. Normally used with multi cavity two plate molds.

Used like the disk gate. 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. In fact the fan gate is an extended design of the side gate. An edge gate located below the parting line or molded surface.

If the injection molding requirements meet the smaller the number of gates are the better it is it would reduce the weld marks. Pinpoint or restricted gate a restricted opening between the runner and molded part. With the gate construction it permits rapid filling of large parts or fragile section mold area with large entry area. Figure 6 2 curved sprue 6 3.

The runner and gate system used in plastic injection molding is responsible for directing molten plastic from the nozzle of the molding machine into the cavity of the tool. The gate architecture and its location affects cycle times tooling costs lead times the location of witness marks and many other potential defects that are commonplace for injection molded parts. 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. Plastic injection molding fan gate design 4.

If unavoidable the weld marks should be designed on the unimportant surface and non weak parts of. You can read all the content. 6 2 the edge or fan gate an edge gate is primarily used for molding parts with large surfaces and thin walls. Its structure is similar to the side gate but gate width is bigger and fan shaped.

It is used to create uniform flow into wide parts purpose 1. Used in large size molded product. 1 injection molding gate is a small opening between the runners and the mold cavity. It is used for the plastic part of a large area.

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.
