Electron Beam (EB) processing is extremely precise and can be controlled and measured to provide the exact level of cure desired. Both the dose (the amount of electrons) and the depth of penetration can be precisely controlled. This is done with a computerized system that controls the dose and penetration depth of the electrons.
High voltage is applied to tungsten filaments inside a vacuum chamber. Filaments are super-heated electrically to generate a cloud of electrons. Electrons are drawn from the cloud and accelerated to extremely high speeds. Accelerated electrons pass through a foil window to penetrate the target product. Electrons cause desired molecular changes in the product.
