Process rolls for industries such as paper, printing and steel can be refurbished either in-situ or at Alphatek’s purpose built facility.
Preparation is by Machining, Grit Blasting. Applied Coatings include: Thermal spray carbides, Metal Alloys, or Ceramics. Fluoropolymers. Finishing: Grinding, Polishing
In a Thermal Spray, Plasma (APS) Process, Anilox rolls are sprayed with a ceramic Ni based sub layer with a Cr Oxide based top coating and subsequently diamond ground and laser engraved to produce a surface profile which will deliver a controlled amount of ink to the paper being printed.
Bearings and Seats
Because of the harsh environment in which they operate, the bearings of rubber-coated rollers within the printing industry can become clogged and damaged by all manner of debris and ink deposits causing wear and damage to the bearing and bearing seats. Thermally Sprayed coatings applied to the affected bearings and bearing seats can restore functionality and greatly extend life.
