Injection Mold Fan Gate Design

In fact the fan gate is an extended design of the side gate.

Injection mold fan gate design.

Used like the disk gate. Pinpoint or restricted gate a restricted opening between the runner and molded part. 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. 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 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. It has the following advantages. Normally used with multi cavity two plate molds. Ring part must get filled first and then the cylinder part otherwise the weld will occur.

6 2 the edge or fan gate an edge gate is primarily used for molding parts with large surfaces and thin walls. 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. 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. 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.

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 purpose 1. An edge gate located below the parting line or molded surface. Fan or edge gate a common gate located in the sidewll of the part to prevent restriction of resin flow.

If the injection molding requirements meet the smaller the number of gates are the better it is it would reduce the weld marks. It is used to create uniform flow into wide parts. 1 injection molding gate is a small opening between the runners and the mold cavity. Plastic injection molding tab gate design 3.

You can read all the content. If unavoidable the weld marks should be designed on the unimportant surface and non weak parts of. Normally used with thin wall parts. 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.

This is only possible how ever for certain materials such as thermoplastic elastomers. Its structure is similar to the side gate but gate width is bigger and fan shaped. Figure 6 2 curved sprue 6 3. Thereby keeping the cross sectional area constant.

Molded part in the mold which is now loaded in the center. Plastic injection molding fan gate design. Design fan gate is similar to the side gate but width of gate is bigger and has fan shaped. With the gate construction it permits rapid filling of large parts or fragile section mold area with large entry area.

But the test results show that. Plastic injection molding fan gate design 4. Have a great influence on product appearance dimensional physical characteristics and production efficiency. It is used for the plastic part of a large area.

Their location quantity shape and size etc.
