Increased use of vacuum in glass moulding

The global glass community is reshaping to face the tough competition by other container solutions. The cost of hollow glass products is under pressure and manufacturers seek improvements wherever possible.

Productivity is the ratio which is monitored carefully. Objectives are

  1. Reduction of the rejection rate,
  2. Reduction of the hollow glass container weight,
  3. Increase of the manufacturing speed,
  4. Reduction of the allover power consumption in the plant. Pneumofore is familiar and comfortable with such targets.

The idea is to strongly support all sustainability-oriented strategies by offering its almost centenary experience to optimize the pneumatics involved on the IS machines. The 24/7 operation of glass furnaces pretends continuous availability of compressed air and vacuum. Pneumofore understands the reliability and efficiency requirements of modern glassworks. Most frequently the machines are sold with RoI calculations.

Latest development for Gallo Glass in California is the rotary vane vacuum pump mod. UV100 with 6480 m3/h capacity at 150 mbar(a) pressure with 220 kW nominal power. On the pressure side, Pneumofore can offer up to 5000 m3/h at 2,5 to 10 bar(g) with 500 kW nominal power.
