What are the production methods of aluminum coil insulation?

Aluminum coil insulation is produced using several methods, including lamination, extrusion, and coating. Lamination involves stacking thin sheets of aluminum with insulating material between them. Extrusion is a process where aluminum and insulation materials are pushed through a die to create a continuous profile. Coating methods apply a layer of insulating material directly onto the aluminum coil surface. These methods ensure the insulation maintains its properties under varying conditions, providing electrical isolation and protection against environmental factors.
