Contoured Infrared Emitters

Targeted Heat for Edges and Corners

Contoured infrared emitters for targeted heating (figure: Heraeus)

Heraeus Noblelight GmbH, Kleinostheim, Germany, specializes in light sources and systems, developing, making and marketing infrared and ultraviolet lamps, systems and solutions for numerous applications. Contoured infrared emitters from Heraeus provide targeted heat for edges and corners (Fig.). Thanks to the contoured, non-contact infrared heating element, plastic parts, for example, can be joined together without the need for extra adhesives or other additives. The infrared radiation quickly melts a thin surface layer of the plastic parts. The parts are then joined by pressing them together to form containers. In contrast to contact welding with hot plates, no material sticks to the heat source and the heating step is carried out reproducibly. Another example of contoured infrared emitters is the removal of sharp-edged flash. Flash formation cannot always be prevented on the mold parting line during injection molding. Infrared emitters, which are shaped to follow the contour of the flash, melt the flash with pinpoint accuracy, without damaging the actual work piece. Heraeus therefore offers emitters whose shape, size and range can be chosen with the desired process in mind. The heat is generated specifically where it is needed. Energy losses to the environment are low and the cycle times can be reduced by targeted heat input.
