Common Questions:

1. Burnt
    When aberration and burnt issues occurred, it is because resin is filling faster than air exhaling which will result gasvent to overheat.
2. Overflow:
    There are 2 possible conditions:
    – When temperature of resin gets higher at the tip of seaming, it weakens its bonding strength.
    – Air can filled up the path and blocks resin to flow functionally which will cause ejection pressure to rise and materials to overflow.
3. Not enough fillings:
    Due to air pressure, it reduces the ratio of the flling speed. Even there is no any sign of burnt or overflow.
4. Cell Streak:
    If there are some cells, streaks and mottles occurred, it is because the cells have not been vaporized completely between air and resin.
5. Extensive Cycling Time:
   The higher temperature of resin, molds and slower speed of injection cause extensive cycling time, however, it will not affect the
   quality of final products.

Energy, Time, and Cost Saver:
1. It will reduce the trial die, time and materials if users consider to use TX gasvent the beginning of the design.
2. It will save up to 1/3 to 1/10 of the total cost and time if installing Sintered Vents.

1. Do not touch the surface when Gas Vents  is in use.
2. Use H7/S6 from JIS reference chart.
