mechanical engineering

The surfaces of rolls in production machines must be designed to accommodate the function of the roll in the production process. Whether you are looking for outstanding nonstick properties or good sliding properties, combined with extremely smooth surfaces or traction, Impreglon coating systems can meet your requirements.

We supply durable surfaces that retain their excellent properties even under extreme strain - with maximum production quality. The machine components shown below offer examples of functional coatings. Suitable substrates for these coatings are steel, stainless steel, aluminum, ceramic or plastics (including carbon fiber-based).

Hydropower plant (nonstick coating)

Hydropower plant

The hydropower plant at Augst on the Rhein river near Basel produces up to 250 million kw/h of electricity each year. Seven straight-flow turbines have been in operation at the modern low-pressure run-of-river power plant since 1994. In this special bulb turbine construction type, the turbine and generator form a unit. They are not connected by a drive shaft. The water flows through the generator's rotor.

High susceptibility to wear

The impeller is no more than 2 mm away from the turbine. After approximately 80,000 hours of operation, the excessive force of the water causes the impeller to wear, resulting in grooves up to 10 mm deep. The turbine's output drops drastically when the wear is too great. The power plant can no longer generate the planned amount of electricity.


The MagnaCoat® method coats damaged areas so that the turbine can achieve full output again for up to 80,000 hours longer. The new coating can be applied without refinishing. It must be applied precisely to ensure that it does not exceed the distance of max. 2 mm between the turbine and impeller. This is only possible with mobile devices developed specifically for use on-site. A turbine can be coated within four days, dramatically reducing downtime.

Mobile use, full output

Restores the hydropower plant to its full capacity with only brief downtime.

Polymer coating systems for heavy-duty corrosion protection

MagnaCoat® coatings are thick-film polymer and fluoropolymer coatings with a virtually non-porous surface. They offer excellent corrosion resistance, good nonstick properties and high electrical impact resistance, even at high temperatures. The coatings also provide excellent barrier protection to resist aggressive chemicals.

MagnaCoat® polymer coatings can be applied to all surfaces made of aluminum, steel, stainless steel or other alloys.

Coating thicknesses: 100 µm to 800 µm
Temperature range: -40 °C to +260 °C
Surface roughnesses (Ra): up to approx. 1.5 µm
FDA approved: yes, with certain coating types

Automobile tires (nonstick coating)

Automobile tires

Steel cord is used to produce automobile tires. It is made by drawing out raw wire to ever smaller diameters. Later it is used to form wire mesh that reinforces the tires.

Resistance to wear

Steel wire is drawn over several drums until it reaches the desired diameter. The lower section of the drum running surfaces are damaged over time and deep grooves form. In the past, the drums were lathed to restore the desired sliding surface. However, this can only be done a limited number of times before the drum has to be replaced.


PlasmaCoat® allows the wire drawing drums to be refurbished again and again. It has greater resistance to wear than the original surface and thus increases the service life. The coating lasts about one year.

Reduced costs and time requirements

Eliminates the very high cost of repeated lathing and purchasing new drums.

Wear-resistant combination coatings

The PlasmaCoat® coating procedure combines the outstanding surface hardness and wear resistance of thermally sprayed metal or ceramic coatings with the nonstick and sliding properties of polymers and fluoropolymers.

PlasmaCoat® combination coatings also offer very good traction properties with various degrees of surface roughnes and profiles. An embedded metal or ceramic coating can be used as a substrate for the coating that protects from wear.

Coating thicknesses: 80 µm to 295 µm
Temperature range: -40 °C to +270 °C
Surface roughnesses (Ra): 1.5 µm to 17.5 µm
Surface hardness: 28 to 70 HRc
FDA approved: yes, with certain coating types

Hot melt adhesive application machines (nonstick coating)

Manufacturing of hot melt adhesive application machines

Extensive cleaning requirements

Adhesive residue sticks to hot glue tanks and application heads


With SafeCoat®, the nonstick effect between the adhesive and the tank is improved even further. Even unhardened liquid hot melt adhesive can be removed from the coated surface without leaving residue.

Faster cleaning, reduced corrosion

Shorter cleaning times, improved protection from damage.

Functional coatings based on fluoropolymers

SafeCoat® coatings improve the nonstick and sliding properties and provide corrosion protection for components. A variety of different polymer and fluoropolymer coatings create an optimal characteristic profile for any application.

SafeCoat® nonstick coatings prevent adhesion, improve production processes and reduce the cleaning required for machine components. By reducing the frictional resistance, SafeCoat® helps to speed up production processes and removes the constant need for lubricants. SafeCoat® corrosion protection coatings increase the service life of machine and system components and reduce unnecessary machine downtime.
