industry. Over the last 20 years, the company has supplied pipe cutting machines that cover a diameter range from 28mm to 6,000mm. All HGG machines can be supplied with a CAD-CAM system, with connections available for AutoCAD, Pro-Engineer, X-Steel and Solid Designer. The company can also tailor-make other CAD-CAM or post-processing systems. developed products are first installed in one of its subcontracting companies, in order to gain practical experience with the products, and to improve them.

Guild and manufactures coil end joiners and horizontal strip accumulators, with brand names including ZipWelders™, Supercoils™ and Superloops™. The company also has complete entry equipment in their product line, including single and double uncoilers, outboard coil retainers, speed funnels and flatteners. The company will present its range of coil end joining technology along with information and brochures for its complete product line. Guild coil end joiners together with their strip accumulators can eliminate downtime during coil changeover. Guild personnel will be available to discuss ways to speed up the coil changeover process to completely eliminate downtime. International designs Formitt Metal Labs, part of Hess Industries, USA, will showcase its custom manufactured, water-cooled catalytic converter housing for marine electric generator applications, that eliminates carbon monoxide (CO) gas from the engine’s exhaust stream. Carbon monoxide poisoning has become a recognised risk for boaters, leading to the need for this exhaust device. As reported in the June/July 2007 issue of Professional Boatbuilder magazine, “ Statistical data revealed nearly 390 cases over a period of eight years in the Lake Powell, Utah area alone. According to USCG and NIOSH studies done at this lake, 64 people died from CO produced by onboard generators, 10 deaths were attributed to gas from propulsion and other engines .” Using hollow tube spinforming and assembly technology, the dual chamber 304 stainless steel assembly secures the catalysts in the inner tube, separating it from the water cooled outer jacket. The water cooled jacket is required to meet temperature restrictions on exposed surfaces in marine applications. Formitt spinforms/fabricates the tubular parts, wraps and inserts the catalyst, assembles and TIG welds the connecting flange. Hess Industries, Inc USA Booth 22036 Website : www.guildint.com

Hisen Enterprises Co Ltd Taiwan Booth 25099

Formitt uses spinforming, flowforming and assembly technologies to create hollow tube symmetrical and asymmetrical shapes, fabrications, and assemblies using flat stock or tubing in both ferrous and non- ferrous metals, including stainless and high alloy steels. eliminates the need for welded tube end-cones, enhancing overall component quality and reliability. Formitt hollow tube fabricated assemblies may include the insertion of filtration elements, heat exchange components, catalytic elements, or others. The company’s metal tube spinforming technologies are currently used in the automotive, HVAC, filtration, marine industries and others. › Formitt Metal Labs has developed a catalytic converter housing to eliminate CO gas Spinforming technology

Founded in 1967, Hisen Enterprises Co Ltd is a manufacturer of transistor generators for pipe welding and heat treatment and high frequency machines. A new transistor generator has been developed using Hisen’s latest technology that incorporates new-type transistor devices. According to the company, it has drastically reduced the size of conventional transistor generators and caters to the diversified applications of tube welding and heat treating industries. The features of this new generator include a frequency range of 500Hz to 440kHz at an output range of 2-1,000kW, a power factor of 0.95, and power conversion of 90 per cent efficiency. In cases of short time heating, it provides increased output power to solve problems. Because transistors are used instead of vacuum tubes, the level of input power can be reduced by over 22 per cent and cooling water can be saved by up to 50 per cent. The comprehensive solid-state and low- voltage system forms a compact design that reduces the required installation space. A reduction to one-third of the space required by other conventional vacuum tube oscillator models has thus been achieved. The water cooling circulation system (optional) helps to address concerns with water temperature levels and helps prevent problems. In addition to Hisen’s transistor generator, the company also provides quality high frequency machines such as high frequency
