Infrared Weld Tooling

Advantages of Forward Technology Infrared Tooling:

  • Over 95% of all tooling is designed and manufactured for your application by our in-house Tooling Design and Fabrication department in Cokato, MN.
  • This in-house capability insures optimal quality and scheduling control as well as reducing time requirements in the event of product design changes.
  • No charge/obligation complete application review and joint design assistance.
  • Full prototyping capability.
  • All tools are designed for ease of maintenance, adjustment, and maximum life.
  • Tools provide support and location of joint area as well as accurate alignment throughout the welding process.
  • Virtually every tool is thoroughly tested and debugged at our facility on equipment in our laboratory.
  • Full start-up service/support at your facility is available.

Standard Infrared Tooling

  • Precision CNC cut holding fixtures supports joint area of each part half.
  • Holding fixtures can be split if necessary to accommodate part-to-part variations or for welding warm/hot parts.
  • Hardened steel fixture top plates (metalized by black oxide, chrome plating or anodizing)
  • Steel, aluminum, urethane, or acetal tooling components.
  • Lightweight aluminum backing plates
  • Heavy-duty slides used for support & part retention in areas where clearance is needed for loading & unloading on lower tooling.
  • Custom grippers and vacuum cups used to secure parts in holding fixtures.
  • Mechanical positive hard-stops on each fixture and infrared platen.
  • Control depth of melt and weld/seal dimensions.
  • Provide assembled product consistency
  • Eliminate risk of cold joint (all molten material being extruded from joint by excess travel)
  • Adjustable for part to part variance
  • Precision glass encased emitters contained with platen assembly designed for uniform intensity across all joint surfaces.
  • Constant air cooling of all emitter envelopes to insure long life.

Infrared Tooling Options

  • Part presence sensors verify part presence/position prior to allowing machine to cycle.
  • Part eject eases removal of welded parts from tooling.
  • Quick change system for customers using multiple tools in one machine.
  • Tool coding utilizes RF Tagging to automatically identify the application and select the correct program/setup.
  • Infrared platen & tooling fixture cart with casters for storage and easy relocation of infrared assemblies and tooling.

Advantages of Glass Encased Emitters vs. Ribbon Style Emitters

  • Improved safety, no exposed live conductors.
  • Air currents can create SIGNIFICANT changes in temperature and wattage when conductor is exposed to air currents.
  • As encased conductors are held under tension, they offer much better resistance to sagging as found in ribbons style emitters.
  • Conductor is isolated from product – no contact is possible, minimizing risk of damage to the conductor.
