Coating - steel and metals - Import export

The processing of granules into coated long products requires high precision with tools and machine settings as well as sound expertise in the specific characteristics of the materials. As an extrusion specialist of steel cables and other long products such as wires, glass-fibre rods, we offer a wide service range: Plastic coating from ca. 0.5 to 24mm, PA, PE, PP, PUR and PVC and more, additives for special requirements, such as the UV and water resistance, circular cross sections and special dimensions and stock colours or your own selection.

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.

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.

Functional and decorative coating systems In addition to coatings for Coil Coating applications and related areas, SI-Coatings GmbH develops and produces individual paints and varnishes for any application. These are technical, functional and decorative coatings.

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).

This coating system is mainly used for the coating of cold rolled strip, but can also be applied to other metals. It is applied in the last processing step and enables a special gliding ability and heat resistance on coated surfaces.

Rubber-to-metal bonding 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. Plastic-to-metal bonding 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.

We are able to produce various shades of high-quality decorative polyester top coats in small and very small batches using a paste system – resulting in a very competitive pricing for our customers.

The EM ACE600 sputter coater is a versatile high vacuum film deposition instrument for your FE-SEM and TEM applications. Whether you need to •enhance contrast by a fine-grained metal layer, •produce nanometer thin but robust carbon films, •rotary shadow your sample to make smallest features visible, or to •move into cryo-coating, the ACE600 coater will offer the optimal solution to see more, and this every time.

Requirements for products working in a high temperature fusing environment include continuously increasing requests for longer part life, higher print speed, and better print resolution involving ongoing material and process innovations. Our goal is to find the best combination of the following properties: Thermal resistance Thermal conductivity Abrasion resistance Anti-adhesive surfaces Elastomer hardness Substitution of Metal Substrates by Polyimide Belts Fusing by heat and pressure in digital printers has previously been realized with anti-adhesive coatings on aluminum or steel cores. These metal substrates have been increasingly replaced by seamless thin walled polyimide belts due to energy-saving environmental regulations and the growing requirement for “instant on” printing devices.

Mass coating of small parts using the hot drum process Coating with the Rotamat is the economical solution for the surface finishing of mass-produced small parts made of elastomers, metal or wood - for example, O-rings, handles, springs or screws. Even geometrically complicated or particularly sensitive parts leave the machine perfectly coated and dry. The coating process is fully automatic, so that the time-consuming insertion or suspension of the parts on racks - which is necessary with conventional automatic coating machines - is no longer necessary. The Rotamat is suitable for a wide variety of coating agents. Typical applications are: — Decorative coating — Bonded coating — Adhesive coating — Anti-corrosion coating — Insulation coating

In addition to laser cutting, edging and welding, we at W & K Metallverarbeitung also offer various services in the field of post-processing and surface treatment either internally or through reliable external partners. We execute all requirements according to your required factory standard. Would you like a final assembly of your products? This is also possible with us. For coating and surface treatment, we work together with high-performance partners. • Powder coating (maximum component size 1.6 x 3.0 x 8.0m (W / H / L)) Galvanized galvanizing (blue, yellow or black chromating, max.
