Triple-Engineering is specialised in sales, optimization and of polishing rolls. Polishing rolls are used for smoothing all types of web-shaped products.The higher the actual line load, the more necessary the dimensional stiffness of the polishing roll.
Our polishing rolls are made by cast iron and on the basis of cylinders
Constructed cylinders rolls
Manufactured according the requested specifications
The basis of our cylinder rolls are tubes.The materials are steel, stainless steel, aluminium or combinations.
The quality of the weld seam is an important component for the quality of the cylinder. Therefore, welding is one of the core competences for cylinder construction. We place great value on this. Our partners are certified companies.
We build in this range: heating and cooling rollers, laminating rollers, calendars, printing rollers and embossing rolls, et cetera.
Chilled Cast Iron
Standard chilled cast rolls
The casting process for chilled cast iron and grey cast iron is using the static castic proces. The horizontal centrifugal casting is used for smaller rolls.
In this range we built: mixing rolls, thermo rolls, calender rolls, heating and cooling rolls, laminating rolls, printing rolls, refining rolls, flaking rolls, cracking rolls and embossing rolls.
