Vertical Hydraulic Infrared Welder

The VHIR-1445 is a vertical infrared platen orientation, hydraulic motion controlled infrared welding system capable of welding parts up to 14" x 45" (356mm x 1143mm) or multiple smaller parts. Customized variants of this model are available.

When compared to horizontal platen systems, vertical systems typically:

  • Reduce risk of molten material possibly dripping onto the infrared platen during the melt step (resulting in premature emitter failure).
  • 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 in the parts themselves (required for accurate machine pick-up of one part half on horizontal systems).

Standard Features

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 wear by user programmed variable tool mounting jaws and infrared platen carriage pressures and speeds, including soft-touch contact of part halves to each other during the Weld (Seal) step.

Digital Dual IR Controllers provide (4 + 4) Eight Zone Infrared Intensity Control via PLC/HMI with Emitter Burnout Alarm and Digital Incoming Line Voltage Monitoring with settable Alarm Limits. Alarms prevent operation of equipment in the event of emitter failure or if plant voltage rises/sags outside of user-defined limits (affecting actual infrared energy output).

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

Allen Bradley CompactLogix PLC with PanelView Plus 7 - 700 Color 6.5in Touch-Screen Graphical Display simplifies parameter input and allows the following to be displayed:

  • Melt, Weld (Seal), & Open Time Digital Control & Display
  • 5 Digital Infrared Energy Control Steps (10% - 100%)
  • Resettable Parts Counter
  • Non-Resettable Total Machine Cycle Counter
  • Diagnostic Display
  • Machine Alarms (history storage of up to 99 alarms)
  • 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.

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

Pneumatic Power Sliding Door with Zero Force Cycle Activation Switch and Door Safety Tapeswitch provides optimum personnel protection while reducing operator fatigue.

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

Vent Hood with Exhaust Fan evacuates airborne smoke from the operator location.

Sequence of Operation

  • 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.Infrared platen advances between part halves.
  • 6.Holding fixtures close to make contact with precise mechanical hard-stops on the infrared platen which maintain spacing between the parts and the infrared platen without actual contact.
  • 7.Infrared platen energizes, heating joint areas of part halves.
  • 8.Infrared platen de-energizes and holding fixtures retract away from infrared platen.
  • 9.Infrared platen retracts.
  • 10.Holding fixtures apply part halves together, welding parts together.
  • 11.One holding fixture releases its clamping mechanism.
  • 12.Holding fixtures open, retaining welded part(s) in one fixture.
  • 13.Safety door opens.
  • 14.Operator unloads welded part(s).
