Best Used For: 

Hard base onto your part and then impregnate one of our Low COF release agents into that coating.

Machined Crowns

Roller crowning is intended to ensure proper web alignment and helps minimize the effects of deflection. Materials include several types of aluminum and steel.

Benefits: 

Minimize the effects of deflection.

Best Used For: 

A wide variety of applications.

Mirror Finishing

Chrome plating is used where a “mirror” finish is needed.

Benefits: 

Mirror finishing is a very smooth surface and can either decrease or increase web/roller friction.

Best Used For: 

A wide variety of applications.

MODEL 450A125 - 4.5” dia. x 0.5" wall aluminum wall

Nickel Plating

Electroless Nickel plating offers some advantages over chrome plating. It has a better resistance to corrosion with relatively thinner coatings than chrome.

Benefits: 

Electroless Nickel plating –in the as-plated condition has a hardness of approximately 50Rc. It can be heat treated by baking to a hardness of approximately 70Rc.

Best Used For: 

Electroless Nickel plating can be applied to aluminum and steel.

Nip Rollers

Our nip rollers are available in alloy steel, carbon steel, and stainless steel. Nip rollers are also known as pinch rollers and by various other names.

Benefits: 

Proper selection affects product quality and line speeds.

Best Used For: 

They are used to press two or more sheets together to form a laminated product.

Overlaying Weld

Overlaying welds are utilized to help build up a roller’s body to a larger diameter, repair existing faces on rollers, or incorporate different properties.

Benefits: 

Re-store to original and critical dimensions; thus reducing replacement costs.

Best Used For: 

Core and Journal Repair

Physical Property Testing

We offer a wide rand of physical property testing which enables us to determin material composition and performance expectations in order to optimize application solutions.

Benefits: 

Compression Load Deflection Testing, Hardness Testing, Tensile, Elongation and Tear, Ozone Resistance, Surface Energy (Wettability), Surface Finish (Roughness), Thermal Conductivity

Best Used For: 

Wide range of problem solving applications and analysis.

Re-shelling

Re-shelling is considered if the outer shell is damaged or has experienced internal corrosion, and it’s possible to cut off the other shell and re-shell.

Benefits: 

Reduce costs in repair or replacement situations.

Best Used For: 

Heat Transfer and Chill Rolls

Release & Cleanability

Certified DuPont Licensed Industrial Applicator (DLA), user of Whitford coatings, and we blend our own, resulting in leading the industry in release coating services for a variety of industries.

Benefits: 

Non-stick and release properties on surfaces.

Best Used For: 

Our coatings reduce the clean up and build-up of such materials as starches, paints, adhesives, latex, rubber, food, paper, ice, sugar, resins, tapes, inks.

Reverse Tapers (concave crowns)

Spreader rollers’ grooving can take many forms including: herringbone pattern, chevron groove pattern, and reverse tapers (also known as concave crowns).
