If you are looking for a MOLD VENTING INSERT
Molding defects countermeasure parts "GASEXIT"

Our Mold Venting parts are made of a fine through-hole porous material, so it has an optimal balance as a "hard to flow resin and allowing gases to pass through" vent hole.

Due to it's effect, it is possible to improve molding defects (burn, clouding, Sliver streak, weld line, short shot, shrinkage, warpage, flash, etc.) caused by gases. It also extends the mold maintenance cycle and improves the mold shot durability.

Since gases accumulated in the nozzle of the molding machine flowing into the product is the cause of defects, we have a lineup of products that prevent the gases from flowing into the product. In addition to general-purpose resins, it can also be used for easily flow-able resins such as PBT (GF), PPS (GF), PA (GF).

GASEXIT RUNNER GASEXIT Runner is an insert that discharges gas laterally between the P/L surface and the plate. (Product patented) This product was developed with the purpose of discharging the gases that flow in advance into the product part . Given that it is only a Φ10~Φ15 machining on pockets and grooves, it is a product that can easily be used as a gases venting measure for existing dies. Click here for details >

GASEXIT EP It can be installed easily by simply replacing the ejector pins currently in use. By installing it in the cold slug section,as with GASEXIT RUNNER, you can remove the gases before they flow into the product section. Of course, it can also be installed in the product part, so you can easily take measures to vent gases even from the product part. Click here for details >

GASEXIT BUSH It can be easily installed by simply replacing it with the sprue bush currently in use. By providing a puddle in the end part of the sprue, it is possible to significantly improve the gas venting effect. A sprue lock bush type is also available, it can be also installed on the cold slug side. Click here for details >

GASEXIT CUSTOM Please consider this option when you cannot install GASEXIT in the runner section and cold slug section or you want to improve if further. Since it can be manufactured according to the insert shape of each product, it is possible to vent gases in a wide range. 3D curved and seamless gases venting inserts can be manufactured.

GASEXIT Introduction

The video shows a state where air is being blown from the exhaust hole side and a thinner is being applied to the GAS EXIT surface.

● At the time of actual molding, gas is discharged from the GAS EXIT surface (the surface through which the resin passes = the surface from which the bubbles in the movie appear) to the exhaust hole side.
● It has a fine through-hole structure that does not allow thinner to penetrate.

​This way, GASEXIT is capable of passing a large amount of gases, with a fine through-hole structure that does not allow thinner to penetrate, Since it has a structure that does not easily cause clogging due to resin flow during injection, it is effective as a Mold Venting measure during molding.
