Steel & aluminium processing

Metal processing: the best answers to your conveying, pressing and guiding needs
Polyurethane coatings considerably prolong the service lives of pinch rolls as well as painting, guiding and conveying cylinders in the steel and aluminium industries. Using the ribbon flow method, we can apply a coating of polyurethane up to 30 mm thick to a cylinder core in one pass. There is hardly any more cost-effective or faster way. At the same time, both the quality and the mechanical properties are outstanding.

Our polyurethane Intec RTE material excels in terms of wear resistance and resistance to oils, greases and solvents. Our [PUR] coatings perform particularly well under dynamic loading and when abrasion and tear propagation resistance plus good rebound (resilience) qualities are required.

Furthermore, the INTERNORM cold- and hot-casting polyurethanes enable our customers to employ cast plastic parts profitably.

Coil coating cylinders:

INTERNORM [PUR] Intec CI has become well and truly established in the coil coating industry. Thanks to their outstanding solvent resistance and good swelling behaviour but at the same time excellent resistance to abrasion and cuts, polyurethanes are being used more and more for the painting of steel coils. We would be happy to refurbish and recoat your old cylinders. Our cylinder assembly shop can provide you with a complete service, including recoating, ball bearing maintenance, seal replacement, balancing, etc. Put our service to the test!

Outsourcing of cores –
exploiting expertise

As a supplier of cylinders, INTERNORM has excellent connections to metal roller manufacturers worldwide. Moreover, being part of Grimme Group means we have good access to metalworking machines. We can therefore easily offer you complete cylinders including core, ball bearings, seals, pillow blocks, etc.

Examples of applications

CYLINDER WITH COATED SPIGOT

Blue cylinder cast using rotational moulding, with spigot coating cast and ground beforehand. Spray control rings are later mounted on the spigot coating.

EJECTOR RINGS

Yellow ejector rings with high-precision polyurethane coating for use in steel processing plants. We are happy to supply the metal rings as well.

RED EJECTOR RING

The side of the red ejector ring was ground with a very tight width tolerance. The concentric running accuracy is < 0.05 mm!

Andruckrolle-mit-Polyurethanbeschichtung

PRESS ROLLER WITH POLYURETHANE COATING

Diameters up to 1500 mm are possible with polyurethane coating thicknesses of up to 30 mm. The surface is ground and can be supplied with an Ra value as low as 1.2 µm.

GROUND IDLER ROLLER

For mounting beneath endless steel belts. The cuts-resistant polyurethane protects the surface of the steel against scratches, also tensions the steel plates and guides them around the curve.

PAINT APPLICATION CYLINDER

INTERNORM [PUR] Intec CI is especially suitable for painting coils in steelworks. The excellent resistance to swelling caused by paints and cleaning agents results in precise paint application.

CYLINDER WITH RECESSES

The coating of this cylinder was recessed at certain points so that only the parts of the cylinder coated with polyurethane guide the sheet metal.

CYLINDER WITH [PUR] COATING

his consolidation roll was coated with an oilresistant, ether-based material. This strong, cuts-resistant product is especially suitable for consolidating steel coils.
