Vertical Hydraulic Hot Plate Welder

The VH-1870 is a vertical heat platen orientation, hydraulic motion controlled hot plate welding system capable of welding parts up to 18" x 70" (457mm x 1778mm) or multiple smaller parts. Customized variants of this model are available.
When compared to horizontal platen systems, vertical systems typically: Allow faster tooling changeovers. Allow easier and more positive operator loading and unloading of the tooling. Ensure more precise part half alignment during welding (less scrap) as no special part-part alignment features must be designed into the parts themselves (required for accurate machine pick-up of one part half on horizontal systems).
  1. Operator loads part halves into holding fixtures.
  2. Operator initiates cycle activation switch.
  3. Safety door closes.
  4. Part halves are automatically held with vacuum or mechanical grippers.
  5. Heat platen advances between part halves.
  6. Holding fixtures apply part halves to heat platen.
  7. Holding fixtures retract from heat platen.
  8. Heat platen retracts.
  9. Holding fixtures apply part halves together, welding parts together.
  10. One holding fixture releases its clamping mechanism.
  11. Holding fixtures retract, retaining welded part(s) in one fixture.
  12. Safety door opens.
  13. Operator unloads welded part(s).
