Handling Hot Work Pieces with Vacuum Suction Cups

Schmalz, Inc.

The Challenge
A leading specialist for injection molding and assembly technology for vehicle interiors has to take out hot work pieces from the injection-moulding machine and place them on a conveyor. 

Specifically: internal door handles for automobiles. The parts have a temperature of 176 to 266°F at
the time of removal. The conveyor has an integrated blower which cools the parts. 

The suction cups should leave no mark on the work pieces

The Solution: Non-Marking Cups for Handling Hot Work Pieces

By the usage of Schmalz suction cups type FSG 12 with 2.5 bellows and made of  special heat-resistant material, all requirements are fulfilled:

  • Schmalz suction cups, made of HT1, leave no marks which means that the work piece surface can be painted or chrome-plated easily.
  • Temperature resistance up to 266°F ensures a long cup life-time
  • The form of the bellow cup FSG 12 shows a soft sealing lip for an excellent adaptation to the curved surface. Furthermore, is has a high stroke to facilitate the removal of the workpiece from the mould. 
  • For the vacuum generation compact ejectors SCPM 10 are installed: Due to their minimized size and their light weight they can be placed very near to the suction pads for highly dynamic processes and short cycle times.

Further Information
Schmalz also offers HT2 cups with a heat resistance of up to 480°F. With these cups, Schmalz is the only company to solve handling tasks in the area of hot-forming of sheet metal parts in press lines with suction cups instead of mechanical grippers.

For use in the manufacture of float glass or in tempering processes in the glass industry, Schmalz also offers SPL-HT suction plates, withstanding temperatures up to 1112°F.
