Circular saw blades 50 years’ experience in metal cutting circular saw blade production, along with constant technical cooperation with pipe producers and machine manufacturers, enables Stark to offer the high performance Olympic line, fully dedicated to tube cutting applications. The range includes three kinds of blades: HSS circular saw blades; throw-away TCT saw blades; and resharpenable TCT saw blades.

alloyed steel with high tensile strength, stainless steel, inox and non-ferrous materials. In recent years, tube processing technology has changed greatly. Steel’s higher tensile strength values, greater tube thickness, and faster production line speed are often required by customers. Stark’s Olympic throw-away TCT circular saw blade is an answer to higher customer expectations in tube cutting. The new range includes Olympic 100, suitable for hard material, cutting with low vibrations; and Olympic 200, suitable for stainless steel cutting. Stark Olympic also includes a range of TCT circular saw blades suitable for orbital cutting machines. For cutting tubes with large dimensions, customers are increasingly using orbital cutting heads equipped with two to four blades. Stark developed a new PVD-coated resharpenable blade with special tooth shape, with the aim of reducing the effort during cutting and to reach a longer tool life. According to the section and the material to be cut, Stark can supply different toothing geometries, specially developed to obtain the highest cutting performance.

The HSS circular saw blade is an alternative to TCT saw blades for tube cutting. Thanks to its special steel and PVD coating, it can be used at the same peripheral speed of TCT circular saw blades. The feed rates in the central area of tube crossing are claimed to be 40 per cent higher than feed rates of TCT saw blades, and so the blade cuts thin tubes 20 per cent faster than TCT saws. It is suitable for carbon steel,

compounds with chemical resistance. Products from the Schulamid range related to fluid system connectors provide fibre reinforced polyamide grades with high chemical and zinc- chloride resistance. New Schulaketon products offer reinforced aliphatic polyketones that can replace long-chain polyamide compounds for high-duress tube connectors, as well as non-reinforced polyketones that can substitute high- performance thermoplastics for tube and wire applications.

that included Cotene™ and Icorene™ thermoplastic coating powders, which are free of Bisphenol A (BPA), volatile organic compounds (VOC) and isocyanates. The company also exhibited engineered plastics products for tube extrusion applications, such as Schulamid impact-resistant and zinc chloride-resistant polyamide grades. Schulamid FR is REACH and WEEE compliant and has halogen-free flame-retardant polyamide grades. Schulablend offers UV-resistant ASA/PA blends with a matte surface finish, and Polyfort provides polyolefin

A SCHULMAN is an international supplier of plastic compounds and resins. The company’s speciality powders and engineered plastics products offer solutions that allow customers to meet the specific regulatory requirements of the tube industry, such as the Waste Electrical and Electronic Equipment (WEEE) directive and the Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). The company has developed a comprehensive product portfolio with expertise in the wire and tube market. At the 2014 wire and Tube trade fairs, A Schulman exhibited products
