Adhesive Bonding of Filter Assemblies Filter assemblies are produced by curing a thermosetting material between a paper assembly and a steel or aluminum cover. As shown below, dual pancake induction coils are used in a static setup to provide heat to the top and the bottom plate. A dynamic setup utilizes long pancake coils for the heating. Heat cycle times are in the order of 5-10 seconds. Typical fastener materials are steel, titanium and brass.
Induction is used to localize the heat to the thread areas.
A powder spray is then sprayed on the heated area. The heat causes the powder to stick and form a patch on the threads. Production rates of more than 10,000 pieces per hour are achievable with induction . These links will take you to the welcome page of our Applications Database.
