Hot Plate welding is widely used for the most challenging materials and large part assembly with high strength and hermetic requirements.  During hot plate welding, both part halves are held rigidly in position against/near a thermally heated platen to melt the joining surfaces. The materials are then quickly separated from the heated source, driven together and allowed to re-solidify under pressure.

Forward has manufactured hot plate welding systems since 1965. Our experience has resulted in the design of equipment based on ultra-rigid construction and detailed melt control to ensure precise repeatability of part quality, year after year of production. These years of experience have allowed us to develop and build Hot Plate machines that are actuated via pneumatics, hydraulics, or servo. All three offerings have their own benefits and drawbacks, work with a Forward Engineer today to determine the best suite control option for your application.

Vertical or horizontal platen hot plate welder configurations are available.  From manually loaded and unloaded machines to semi and fully automated in-line systems, Forward offers the widest array of standard products designed to accommodate a most product sizes.

About Hot Plate Welding

Hot plate welding offers the highest joint strength of any weld process when welding PP,PE, TPE and EPDM materials.

Ability to weld large parts and complex shapes and compound contours with little regard to part and joint geometry and so much more.

  • Significantly smoother flash with less particulate than other assembly methods.
  • Compatible with most thermoplastics.
  • High strength, hermetic welds are typical.
  • Multiple parts per cycle can be welded.

Designing for Hot Plate Welding

The hot plate welding process produces a welded joint which, in many cases, yields a weld strength that is consistently equal to or stronger than the adjacent areas of the part. Learn more on designing for hot plate welding.

As a result, the weld area can most often be exposed to the same strains and stresses as any other area of the part.

  • Acrylonitrile Butadiene Styrene (ABS-Cycolac)
  • Acrylic-Styrene-Acrylonitrile (ASA-Geloy)
  • PolyOxy-Methylene (POM-Acetal & Delrin)
  • PolyAmide (PA-Nylon & Zytel)
  • PolyButylene Terephthalate
