However, the limitation came when the fasteners were needed for anything that was carrying a load. The company started in 2009 from humble beginnings, acting as a distributor from the couple’s home in Shropshire. One-off usage is permitted but bulk copying is not. Founder Gary Robinson, a toolmaker by trade, now has two CNC machines at his disposal to manufacture one off bespoke fasteners for clients that need unusual threads, heads, shanks, or dimensions, either for some custom application or to replace fasteners that have become obsolete. It has given birth to the GWR Fasteners Colourfast range. This got the cogs turning in Robinson and, convinced there was a way to do it, he began experimenting and developing a similar finish for steel fasteners. “They are each individually done, so it is quite an onerous process, which is probably why no one else has gone down this processing route.”. 229910001220 stainless steel Inorganic materials 0.000 title description 15 239000010935 stainless steel Substances 0.000 title description 12 238000004040 coloring Methods 0.000 title description 8 229910000831 Steel 0.000 “It has been used by the military, pharmaceutical companies, in oil and gas, and even for bespoke architecture.

Hey, guys, this is a basic colouring technique you can use onto stainless steel. It’s a similar kind of finish, but it is not anodising.” It has given birth to the GWR Fasteners Colourfast range. These coloured fasteners are reasonably common in industry and are used in a variety of applications, most of which are to boost aesthetic appeal.

So what’s the secret? “We can’t mass produce them,” said Robinson. The process does of course carry a price premium, which GWR say is in line with coloured anodised aluminium fasteners. The technology of black coloring for stainless steel by electrochemical method was studied. “We get all kinds of requests and have identified many gaps in the market we didn’t even know existed,” said Robinson. Corrosion resistance of stressed NiTi and stainless steel orthodontic wires in acid artificial saliva. The samples supplied to us at Eureka were small, ranging from 10 to 40mm, with the coating applied in no more than a few microns. HHS “What we did was start small by selling on eBay.” The company was highly commended at last year’s British Engineering Excellence Awards where judges commented that, ‘as well as distributing standard fasteners and having a global customer base, GWR has been able to achieve product development and expand current markets in an area that many consider mature.’ Originally the fasteners it supplied were speciality and low volume, but fast forward six years and the company has over 80,000 completed transactions through its eBay store and stocks thousands of products. The effects of ultrasonic frequency and power density (sound intensity) on chemical coloring on stainless steel were studied. We are definitely the only ones that do the process that we do, to get the look that we do.” The obvious question is, why not paint fasteners or powder coat them? “We get all kinds of requests and have identified many gaps in the market we didn’t even know existed,” said Robinson.
