Used in large size molded product.
Injection mold fan gate design.
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.
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.
Used in large size molded product.
This is only possible how ever for certain materials such as thermoplastic elastomers.
Plastic injection molding fan gate design 4.
Used like the disk gate.
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.
Thereby keeping the cross sectional area constant.
It is used for the plastic part of a large area.
But the test results show that.
Figure 6 2 curved sprue 6 3.
Its structure is similar to the side gate but gate width is bigger and fan shaped.
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.
It permits rapid filling of large parts or fragile section mold area with large entry area.
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.
An edge gate located below the parting line or molded surface.
Plastic injection molding fan gate design.
Normally used with thin wall parts.
In fact the fan gate is an extended design of the side 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.
Design fan gate is similar to the side gate but width of gate is bigger and has fan shaped.
If unavoidable the weld marks should be designed on the unimportant surface and non weak parts of.
It is used to create uniform flow into wide parts.
If the injection molding requirements meet the smaller the number of gates are the better it is it would reduce the weld marks.
It has the following advantages.
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.
It is used to create uniform flow into wide parts purpose 1.
1 injection molding gate is a small opening between the runners and the mold cavity.
With the gate construction it permits rapid filling of large parts or fragile section mold area with large entry area.
Their location quantity shape and size etc.
6 2 the edge or fan gate an edge gate is primarily used for molding parts with large surfaces and thin walls.
Ring part must get filled first and then the cylinder part otherwise the weld will occur.
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.
Molded part in the mold which is now loaded in the center.
Have a great influence on product appearance dimensional physical characteristics and production efficiency.
