Air and gas in the mold cavity are discharged out of the mold in a short time to solve problems such as gas contamination, shrinkage, weld line, unformed, and air bubbles.

• Vacuum suction pressure may be freely set.
• The vacuum inlet has two basic connections and is also selectable.
• It can also be applied to molds currently being mass-produced. (Mold modification)
• Resolving gas burning due to gas, gas getting stuck in molds
• Reducing air bubbles and tissue density, dimensional defect rate due to air
• Reducing injection pressure and reducing injection speed (depending on product shape and characteristics)
• Extend mold life by preventing corrosion and removing oil stains in molds (extension of mold cleaning cycle)
• Unformed, contracted, weldline, bubble resolved
• Improved injection performance of thin film products
