Huyghe Formenbau, Lüdenscheid, Germany, finds itself in good company, since the region is home to a good 160 firms specialising in tool and mould-making, a stronghold of the industry. With eight employees, the shop may not be one of the biggest in the industry, but it is one of the soundest financially, according to owner Eric Huyghe. “For the banks, we rank among the Top 10.”

A small shop for a large number of sectors

“As a small company, we have always concentrated in the region around Lüdenscheid and sought our customers here. We so far haven’t had any need for advertising campaigns or for active efforts to attract business,” the owner said.

With a modern machine park and its highly skilled staff, the company is said to feature a broad base and is equipped to produce tools and moulds for a range of sectors. One indicator of the quality of tool and mould-making is the rework rate, which is reportedly practically zero. For tool design sector, the company works with experienced specialists.

One speciality helps create yet another

One shop speciality is moulds–including those with two components–and tools for the large-series production of high-grade system parts for the automotive and electrical industries. In the last few years, the company has focused on two-component moulds and said it has increased its expertise in this area.

EDM and conventional machining are complementary processes at the shop. Each application offers a number of strengths, the owner said. “We combine the two methods so that we can always achieve the optimum of quality and machining speed and respond flexibly to customer requests.” This method is only possible with high manufacturing depth, said to be indispensable for quality.

To ensure tools are built with the required care, the company keeps work in house. “Only then can we comprehensively plan, design and control all work steps,” the owner said. He noted that customers need to be able to obtain the quality they require, quality said to be assured in accordance with DIN ISO 9001 and DIN 2008. These are only the formal guidelines.
