such as copper, aluminium and brass, the inherent strength of stainless steel has been something of a stumbling block for the cold forming process. For engineers today, there is now an alternative to more conventional processes using a safe cold forming technique developed by Dawson Shanahan. This latest development means that stainless steel, as well as other exotic metals such as titanium, can be cold formed using a specialised metallic lubrication and extrusion coating, avoiding the need for hazardous chemical solutions. This unique shell, created by the research and development team at Dawson Shanahan, eliminates the problem of galling, to prevent damage being caused to the components and tooling, which often presents itself in the form of scores or surface imperfections, thus maintaining consistent quality in finished parts. The technique has been endorsed by independent laboratory test results, which show that the process retains all the mechanical properties of stainless steel without any detrimental effect on performance. The advantages of the process will be of particular benefit to those areas of industry requiring robust, ultra-high precision parts, including laser applications, where cold formed nozzles significantly increase cutting accuracy, or in industrial engines where the parts are used to boost overall reliability, while cutting CO 2 and particulate emissions. Equally, other stainless steel components made through cold forming, such as diesel injectors, are generally more reliable especially when used with biofuels, as these fuels can place greater stresses on conventionally manufactured parts. Dawson Shanahan offers a complete solution, with everything from prototype to production being designed and manufactured in-house to reduce both manufacturing lead time and costs. With over 80% of its business being exported, the company’s products meet the demands of a wide range of sectors, including aerospace, automotive, electronics, laser, medical, packaging, plasma, power distribution, telecoms and welding.
