Vertical Air/Pneumatic Hot Plate Filter Welder

The VAF-1015 is a vertical heat platen orientation, pneumatic motion controlled hot plate welding system specifically designed for welding filter assemblies up to 10" D x 15" H x 69" L (254mm x 381mm x 1753mm). Customized variants of this model are available.

The system design is ideal for:

  • Welding stackable filter cartridge modules together.
  • Embedding filter media into plastic end caps (replacing potting operations).
  • Welding of filtration housings.
  • Welding termination fittings (ie: end-caps, twist-lock unions, O-ring fittings, etc..) to the ends of filter cartridge modules.

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.

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

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

Allen Bradley MicroLogix 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
  • 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 qualifed personnel only.

10 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.

Automatic Cycle Start on Manual Safety Door Closure eliminates the need to actuate start button(s). Door is equipped with captured lock and is interlocked to prevent opening while machine is in cycle.

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 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).
