Plastic injection molding fan gate design.
Injection mold fan gate design.
Its structure is similar to the side gate but gate width is bigger and fan shaped.
But the test results show that.
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 is used to create uniform flow into wide parts purpose 1.
It permits rapid filling of large parts or fragile section mold area with large entry area.
Fan or edge gate a common gate located in the sidewll of the part to prevent restriction of resin flow.
In fact the fan gate is an extended design of the side gate.

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.
Design fan gate is similar to the side gate but width of gate is bigger and has fan shaped.
Used like the disk gate.
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 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.
6 2 the edge or fan gate an edge gate is primarily used for molding parts with large surfaces and thin walls.
It is used to create uniform flow into wide parts.
Plastic injection molding tab gate design 3.
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.
2 the gate size is dependent on product weight material and gate types.
Pinpoint or restricted gate a restricted opening between the runner and molded part.
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.
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.
Ring part must get filled first and then the cylinder part otherwise the weld will occur.
With the gate construction it permits rapid filling of large parts or fragile section mold area with large entry area.
It has the following advantages.
1 injection molding gate is a small opening between the runners and the mold cavity.
Normally used with multi cavity two plate molds.
Used in large size molded product.
Normally used with thin wall parts.
Have a great influence on product appearance dimensional physical characteristics and production efficiency.
An edge gate located below the parting line or molded surface.
If unavoidable the weld marks should be designed on the unimportant surface and non weak parts of.
Figure 6 2 curved sprue 6 3.
It is used for the plastic part of a large area.
Plastic injection molding fan gate design 4.
Used in large size molded product.
Their location quantity shape and size etc.
Molded part in the mold which is now loaded in the center.
