Hot Plate Weld Tooling

Hot Plate Tooling Diagram

Advantages of Forward Technology Hot Plate 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 all tools are thoroughly tested and debugged at our facility on equipment in our laboratory.
  • Tools can be designed for use with Forward Technology or most competitor's welders.
  • Full start-up service/support at your facility is available.

Standard Hot Plate Tooling:

  • Precision CNC cut holding fixtures supports joint area of each part half.
Lamp Contoured Hot Plate Holding Fixture
  • Holding fixtures can be split if necessary to accommodate part-to-part variations or for welding warm/hot parts.
Hot Plate Holding Fixture Split for Adjustment to Warm Parts
  • Hardened steel fixture top plates (metalized by black oxide, chrome plating or anodizing)
Lamp Housing Hot Plate Holding Fixture
  • Steel, aluminum, urethane, or acetal tooling components.
  • Lightweight auminum backing plates
  • Heavy-duty slides used for support & part retention in areas where clearance is needed for loading & unloading.
Coolant Reservoir Hot Plate Tooling w-Grippers
  • Custom grippers and vacuum cups used to secure parts in holding fixtures.
Pallet Hot Plate Holding Fixture
  • Mechanical positive hard-stops on each fixture and heat 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
Hot Plate Tooling Hard-Stops
  • Precision cartridge heaters contained with heat platen assembly designed for uniform temperature distribution.
Flat High Temperature Heat Platen                           Contoured High Temperature Heat Platen
  • Teflon coated fiberglass cloth or Teflon coated inserts to prevent material adhesion to heat platen on low temperature applications.

  • Nests are CNC-machined aluminum to match part contours.
  • Nest tooling is designed to minimize risk of blemishing Class-A molded parts – part is supported in fixture tooling primarily only under the weld bead, and adjustable locators allow optimizing fixtured product position consistency.
  • All product support fixture surfaces that are unnecessary for proper support or product location are relived ¼ to 3/8” from the part.
  • Gripping of only edges of lens.
  • Vacuum Cup-Only contact will protect and locate Class-A surfaces.

Hot Plate 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.
  • Pre-heat station allows pre-heating a heat platen prior to installation to minimize tooling change over time. 
  • Heat platen & tooling fixture cart with casters for storage and easy relocation of heat platen assemblies and tooling.
