In coil coating, an organic coating is applied to the surface of a metal strip in a continuous process.
The HUEHOCO portfolio includes both decorative and weather-resistant coatings as well as system solutions for a firm bonding of the metal strip with various rubber compounds and/or various plastics. For technical applications, there are also high-temperature resistant and non-stick as well as anti-friction systems, directly rubber- or plastic-coated metal strips.
Since 1989 we have been the first company in the world to offer our customers the opportunity to have their goods delivered "endlessly" wound with more than 200,000 metres in a single strip on metal or plastic spools.
Depending on our customers' requirements, we can process all wrought aluminium alloys, stainless steels, steel grades and non-ferrous metals available on the market in various degrees of hardness.
We find decorative coatings wherever an attractive or optically effective surface is required. Examples include the construction sector (interior and exterior), office organisation, interior decoration, reflectors, veterinary medicine, labels, roof construction and other niche segments.
Thermo-reactive bonding agents
Our adhesive build-up provides strong bonding between our metal carrier and your rubber. With our know-how, we are able to bond a wide variety of compounds such as NBR, CR, EPDM, SBR etc. for you.
Whether PC (polycarbonate), PVC (polyvinyl chloride), ABS (acrylonitrile-butadiene-styrene), CAB (cellulose acetobutryate), PP (polypropylene), TPU (thermoplastic polyurethane), PA (polyamide) and polyolefinic plastics or other thermoplastics as well as duroplastics - we ensure that you achieve optimum adhesion between the plastic and our metal carrier.
Non-stick coating system
Thanks to our in-house R&D at our subsidiary SIC, we have succeeded in creating a permanent anti-stick coating system based on Teflon. The distinctive deep-drawing properties paired with thermal resistance allow it to be used in a wide variety of applications, for example baking moulds.
Partially coated or stripe coated metal strips
An innovation for decorative applications is the stripe coating on our narrow Coil Coating line at First American. This is a complete coil coating process in which we are able to leave tightly toleranced, unpainted stripes on the carrier strip. These give the decorative effect to the finished article, while the coated areas are coated with an adhesive system (e.g. automotive trim material or white coating with a defined black stripe, etc.).
As always, all metal strips available on the market can be used as metal carriers; all coatings can also be used. This leads to a smart product, allowing you a multitude of new, innovative applications.
Rubber-coated metal strips
Our rubber-coated metal strips are used in numerous applications, such as engine and aggregate seals. In addition to NBR, we also coat metal strip with EPDM, NR, HNBR and FPM in thicknesses of 10 μm - 2 mm.
The metal strips can also be coated with an anti-friction coating, which offers extremely high resistance to heat and special sliding ability. The resulting further processing quality enables them to be used wherever parts made of metal strip with sealing, sound-absorbing or vibration-damping properties are required. The very good bonding between elastomer and metal, combined with outstanding deep-drawing properties, shows the superiority of this coating.
The metal strips can also be top-coated with decorative lacquers on both the metal and the rubber coated side (e.g. as a distinguishing feature in the company's own production for top and bottom sides).
Plastic-coated metal strips
In the field of plastics we offer metal strips with PVC plastisol and/or organosol coatings, as well as polyamide plastics. PP (polypropylene), PE (polyethylene), PC (polycarbonate), PET (polyethylene terephthalate) and PLA (polyactide), TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane) and others. These can be produced with a layer thickness of 5-200 μm Depending on the plastic, higher layer thicknesses can also be achieved. In addition, most plastics can also be equipped with antibacterial properties; of course in all colour variations. Although a one-sided coating more common, we are able to apply the same and/or different plastic adhesives for both sides.
Economic efficiency through spooled metal strips
Our tasks also include joint process optimization with our customers in order to enable more efficient production and thus a reduction in set-up and downtimes. Our spooling systems are a good example of this type of cooperation and continuous further development. We connect the strips using state-of-the-art welding technology and rewind them oscillating on a variety of spools
- Strip widths from 1.5 mm up to 60 mm
- Extension of the strip length to more than 200,000 meters in one strip depending on the material
- Individual laying widths from 100 to 400 mm
- Special decoiling racks with decoiling widths of 800 mm and maximum decoiling weights of 2,500 kg
