Horizontal Hydraulic & Servo Hot Plate Pallet Welder

The HHS-5062 is a horizontal heat platen orientation, hydraulic and servo-electric motion controlled hot plate welding system specifically designed for welding plastic pallets up to 50" x 62" (1270mm x 1575mm). Customized variants of this model are available.

The system design is ideal for welding:

  • Pallet top decks to bases.
  • Pallet feet to bases.
  • Pallet sidewall assemblies.

Standard Features

Massive Ultra-Rigid Construction utilizing a tubular steel framework with leveling feet and linear guide shafts & bearings designed for precise tool alignment through decades of use.

Hydraulic System with Proportional Valve Control and Linear Position Transducers offers improved control and reduced machine and coating wear by user programmed variable tool mounting jaws and heat platen carriage pressures and speeds, including soft-touch contact of part halves to heat platen (Melt) and each other (Weld/Seal).

Dual Heat Platen Halves with Servo-Electric Motion Control improves weld strength by increasing speed of heat platens motion thereby reducing open time (between Melt and Weld/Seal steps). Lengthy open times reduce part strength by allowing molten material surfaces to partially solidify or skin-over prior to contact with one another.

Digital Four-Zone Temperature Control via PLC with Heater Burnout Alarm ensures even heating and precise temperature control with temperature alarm limits. Burnout alarm halts operation of the machine in the event of platen heater failure.

Programmable Automatic Machine and Heat Platen Startup (Time/Date Based) saves production time as the machine can be user programmed to automatically initialize warm-up of heat platen and hydraulic system before start of production.

Allen Bradley CompactLogix PLC with PanelView Plus 7 - 1000 Color 10.4in Touch-Screen Graphical Display simplifies parameter input and allows the following to be displayed:

  • Analog Heater Burnout Alarm Setttings from PLC Memory
  • Melt, Weld (Seal), & Open Time Digital Control & Display
  • Individual Meld & Weld (Seal) Pressure & Speed Settings
  • Digital Temperature Control Settings & Alarm Limits
  • Resettable Parts Counter
  • Non-Resettable Total Machine Cycle Counter
  • Diagnostic Display
  • Machine Alarms (history storage of up to 99 Alarms)
  • Data Logging to Customer Computer via Ethernet Connectivity

Multi-Level Passcode Protection limits parameter adjustment to qualified personnel only.

25 Weld Program/Setup Memory allows storage for instant recall, minimizing tool change time.

External 120VAC Duplex Electrical Outlet allows user to easily connect small auxiliary equipment such as computers, printers, radios, etc.

Four Venturi 25.0 in/Hg (63.5cm/Hg) Vacuum Pump System designed to secure even the largest parts within the tooling.

Powered (Electric) Lower Tool Carriage/Drawer allows loading of both part halves outside the welder and makes automated loading/unloading possible. Electric motor/belt drive carriage assembly with Tapeswitch safety protection.

Hinged Access Panels with Safety Interlock Switches allow extensive access while providing maximum personnel protection.

Vent Hood with Exhaust Fan evacuates airborne smoke and particulate from the operator location when welding at high temperatures without coatings.

Sequence of Operation

  • 1.Operator loads part halves together into holding fixture.
  • 2.Operator initiates cycle activation switches.
  • 3.Powered Lower Tool Carriage indexes into machine.
  • 4.Upper tool mounting jaw descends and picks up upper part half and retracts.
  • 5.Part halves are automatically held with vacuum or mechanical grippers.
  • 6.Heat platen advances between part halves.
  • 7.Holding fixtures apply part halves to heat platen.
  • 8.Holding fixtures retract from heat platen.
  • 9.Heat platen retracts.
  • 10.Holding fixtures apply part halves together, welding parts together.
  • 11.Upper holding fixture releases its clamping mechanism.
  • 12.Holding fixtures open, retaining welded part(s) in lower fixture.
  • 13.Powered Lower Tool Carriage indexes out of machine.
  • 14.Operator unloads welded part(s).
