GASEXIT EP is an ejector pin that discharges gas from the realesing part of the ejector pin hole normally machined.
It is a product that can be easily used as a Mold Venting measure because it only has to be replaced in stead of the existing ejector pin.
It can also be installed on the cold slug part where injection pressure is high.
Since the gap on the outer circumference of a normal ejector pin is about 0.01 mm, almost no gas can be released.
Simply replace the existing ejector pin with the GASEXIT EP and the gas will escape from the ejector pin realese part.
The area from which gases escape is more than 4 times higher than that of a normal ejector pin.
Normaly it is a EDM finishing
However, it is also possible to change to a polishing finish type for areas where the surface finish is a concern.
We have a minimum size of Φ2 and a maximum size of Φ16.
There are two types of steel, SKD61 + nitriding treatment and SKH51.
It is also possible to add machining to prevent brim rotation as well as tap machining.
When using the GASEXIT EP for the ejector pin that currently holds the runner using the Z pin, we recommend the cylindrical lock type.
※Z pin can also be manufactured, but the gas discharge surface will be reduced
・A divided insert can not be used in the location where the air trap occurs so gas burn countermeasures cannot be taken.
・A normal gas vent has been machined at the final filling part, but that alone does not improve the gas burn defect.
7 GAS EXIT EPs were installed on the core side of the product side
As a result of installing 3 GASEXIT EPs for the first time, the gas burn defect did not completely disappear, but after installing seven, the gas burn disappeared completely.
The GAS EXIT is a product that is more effective as the number of its installations increases.
