VHIR-1870

The VHIR-1870 is a vertical infrared platen orientation, hydraulic motion controlled infrared 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: 

• 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 ergonomically 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) 

This vertical systems twin motion (left and right) tool mounting platens allows independent control of force/speed on each part half when coming together in the weld phase.

Standard Features:

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

7.5 HP, 1750 RPM, 11.0 GPM (5.6kW, 1750 RPM, 41.6 LPM) 1000 PSI (68 Bar) Maximum Pressure Hydraulic System with Proportional Valve Control and Linear Position Transducers offer improved control and reduced machine wear by user programmed variable tool mounting platen and infrared platen carriage pressures and speeds including “soft-touch” contact of part halves to each other during the weld(seal) step.

Digital Two-Zone Infrared Energy Control with Emitter Burnout Alarm
ensures even heating and precise energy control. Burnout alarm halts operation of the machine in the event of platen emitter failure.

Digital Incomming Line Voltage Monitor with Alarm Limits prevents operation of equipment in the event of 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 hydraulic system before start of production.

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

5 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 1.0 HP, 1725 RPM, 25.0 in/Hg (Dual 0.75kW, 1725 RPM, 63.5cm/Hg) High Capacity Vacuum Pump System designed to secure even the largest parts within the tooling.  Eliminates the need for separate venturi-vacuum systems for each tool.  

Pneumatic Power Sliding Safety 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 allows extensive access while providing maximum personnel protection.

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

Interior Viewing Lights enhance visibility of the welding process for the operator.

Two English Language Manuals provides detailed documentation and instruction of installation, operation, setup, maintenance & troubleshooting procedures.

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).
