Aushärtung von Klebstoffen mit Induktion

Die Aushärtung beinhaltet jegliches Verfahren, bei dem Wärme verwendet wird, um chemische und molekulare Strukturänderungen in polymeren Materialien wie Epoxiden, Phenolen, Polyestern und Silikonen zu katalysieren oder zu initiieren. Diese Materialien werden in vielerlei Hinsicht auf verschiedene Produkte für Bonding, Schutzbeschichtung, Abdichtung, Isolierung und andere Anwendungen angewendet.

Luft-Härtung und Heißlüfter-Härtung werden oft zur Aushärtung kleiner Produktionsläufe verwendet, trotz inkonsistenter Ergebnisse. Große Produktionsläufe werden oft in Chargen in großen Öfen gehärtet, die kontinuierlich laufen müssen. Induktionserwärmung bietet eine viel bessere Lösung für die Klebstoffhärtung.

Curing a coating by heating a steel tube and an aluminum block

The client's oven had a heating time of 20 minutes, so the time savings from a 90-second cycle are considerable. Additionally, induction is a repeatable process, unlike an oven and the induction system takes up less floor space than an oven.

Curing plastisol adhesive on both ends of a filter assembly

Induction heating provides improved distribution of heat, much faster cure time than heat plates previously used, much faster production rate and hands-free heating that involves no operator skill for manufacturing

Über Induktionserwärmung

Über Induktionserwärmung

Induktionserwärmung ist eine schnelle, effiziente, genaue, wiederholbare und kontaktlose Methode, um Metalle oder andere Stromleiter-Materialien zu erwärmen. Das Material kann ein Metall wie Stahl, Kupfer, Aluminium oder Messing sein oder auch ein Halbleiter wie Karbon, Graphit oder Silikon-Karbid. Um nichtleitende Materialien wie Kunststoffe oder Glas zu erwärmen, wird die Induktion verwendet, um einen Stromleiter-Suszeptor wie Graphit zu erwärmen, der dann seinerseits die Wärme auf das nichtleitende Material überträgt.


Modern induction heating can solve many of these problems. Heating with induction provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time, so that the curing process can be completed with minimal energy and time. Improved temperature ramping cycles can be achieved with computer control of the solid state power supply. To eliminate extra steps for loading and unloading ovens, induction heat stations can be incorporated into a production line. Finally, induction heating can be performed in extremely clean environments, vacuum conditions or special atmospheres, allowing for unique curing solutions.

Although induction heating is normally used with metals or other conductive materials, plastics and other non-conductive materials can often be heated very effectively by using a conductive metal susceptor to transfer the heat. Typical RF power supplies for curing applications range from 1 to 5 kW, depending on the parts and application requirements.

Epoxy Curing

Induction heating is widely used for adhesive bonding of metal parts. Adhesive bonding relies on the localized heating of a metallic substrate to achieve accelerated melting/curing of the adhesive. The adhesive bond in this process is cured from the inside out, an obviously desirable condition. All trapped gasses are removed from the adhesive. Induction heating of metal parts to adhesive curing temperatures is utilized in a many automotive processes, such as the use of thermosetting adhesives to produce clutch plates, brake shoes and auto bumper components. Shafts are typically bonded to the squirrel cage rotors in the manufacture of small motors. In copying machines, plastic components are adhesively bonded to aluminum rotors; a thermoplastic glue is used to hold foam rollers on metal shafts. Once the rollers wear out, the shaft is heated and the foam replaced.

Can Ends

Can ends are usually dried by having their centre portions heated to a temperature that is above the temperature that would normally destroy the sealing compound around the edge. This high temperature slowly "soaks" from the centre to the edge over a period of time giving the compound a longer at-temperature heat profile. A special work coil design is used that allows the preferential heating of components on a simple continuous motion conveyor system i.e. not indexing. This means that the production rate can run into thousands of parts per minute.

Bra Underwires

Steel wires are formed into "U" shapes for bra under wires. The ends of the "U" are usually heated and coated with Estrabond powder. By controlling the heating and dipping process, Ambrell has developed a production system that allows control over the final shape of the end protection coating. The use of Estrabond as an end protection is far superior to the usual resin dip process which often fails if the garment washing instructions are ignored and the article is put in a tumble dryer.

Tube & Pipe

In the process of tube coating, induction coil is being used to heat the tube prior to the tube passing in to a powder coating spray booth on the left. The heat generated in the tube cures the surface coating. Induction heating can also be applied for a pipe surface curing application.
