Metal treatments - Import export

Nitriding treatment is a chemical heat treatment process in which nitrogen atoms penetrate the surface of the workpiece at a certain temperature and in a certain medium. The products treated with nitriding have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. The general process of nitriding process :1. Pretreatment: clean, remove oil and dry the metal surface to ensure that the surface is clean and free of impurities. 2. Nitriding treatment: The metal is placed in an atmosphere containing nitrogen and treated at high temperatures to form a nitriding layer on the surface of the metal. 3. Post-treatment: Clean and cool the metal surface after nitriding to remove the residual nitride layer and prevent its oxidation. The nitriding process is of great importance for many industrial fields, such as tool manufacturing and automotive parts manufacturing.

Black oxidation treatment is a commonly used chemical surface treatment method for metal parts, including steel, stainless steel, copper and brass. The principle of this process is to immerse the metal in a heated solution containing oxidized salt, so that the metal surface forms a black oxide film to achieve the purpose of rust and corrosion resistance. This oxide film is usually iron tetraoxide (Fe304), which not only improves the corrosion resistance of the metal, but also gives it a black appearance. This surface treatment is widely used in areas such as precision machining projects, automotive parts, tools and decorations, and the advantages of black oxide include better corrosion protection, reduced light reflection, dimensional stability and aesthetic appeal. In short, the black oxidation treatment is a versatile technology suitable for the improvement and protection of various metal parts.

This material group stands for breaking strength, service life and wear resistance. Due to these properties, quenched and tempered steel is always used where high strength, yield strength and high toughness are required for highly stressed machine parts. C 22 E, C35 E, C 45 E/➔ according to DIN EN 10132 - 3 Depending on the customer's requirements, we supply treatment states from soft annealed to high cold solidified.

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).

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.

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.

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.

Oil-water-separation / degreasing bath treatment Treatment of oil-water-emulsions for surface treatment (e.g. pre-treatment of metal parts for ed-paint), recovery companies (e.g. for the treatment of alkaline emulsions for part washing), and so on. Separation of emulgated oil particles and recycling of the cleaned liquid into the degreasing bath Concentration of oil-water-emulsions for disposal Cleaning of the oil-water-mixture for indirect lead-in Principle of this process: Aqueous degreasing baths content a tenside combination, alkalines like soda, caustic soda, phosphate, silicate and further complex molecules. The degreasing bath is loosing its efficiency, when to oil content reaches some g / litre. External pollutions also degrease the degreasing efficiency. By ultrafiltration, the oil content can be separated from the degreasing bath and the oil will be collected in the concentrate. The degreasing bath will be dumped into a buffer tank and then pumped in the working tank of the

Recovery of acids and acidic rinse waters Additionally to the pickling bath treatment by microfiltration and ultrafiltration, the recovery of acid becomes more and more important. Additionally to sulphuric and hydrochloric acid, also mixed acids (HF / HNO3) can be recovered. The first step of the acid recovery is mostly a sludge separation by microfiltration. Downstream, diffusion dialysis, electrodialysis or nanofiltration is used for metal separation. For the treatment of rinse waters, OSMO Membrane Systems GmbH offers reverse osmosis or electrodialysis plants.

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
