Erodex, a specialist in the provision of EDM supplies, graphites and graphite machining, is celebrating 20% growth over the past 12 months, following a period of substantial investment.

The company has invested a total of £1.75m in machinery and premises as part of an expansion strategy which has included record orders for a newly formed tool room and diversification in product ranges. The growth is the third year in a row that the company has set record levels for total revenue, and includes the company bolstering its workforce with an additional 17 employees.
Director Steve Rolinson says: “We are extremely pleased with the progress of the company over the past 12 months, not only with regard to the ongoing success of the new tool room following our investment in that, but also in increased market penetration for the provision of our graphite materials and EDM supplies.
“We are on a constant journey to help our customers improve processes,” he continues. “For example, we recently reached an exclusive agreement with Houghton International to handle all UK distribution for their dielectric EDM fluids. For 15 years we have been supplying a product made in Canada called Commonwealth Dielectric EDM 244 and Super Supreme. The company producing that was acquired by Houghton and the production of that dielectric has now been brought back to the UK. We are extremely pleased that Houghton demonstrated such confidence in us by establishing our own exclusive agreement with them.”

Hertford-based Neptune Engineering has continued investing in the latest Sodick die-sink technology by acquiring a new AD35L machine from Sodi-Tech EDM. Offering up to 50% more speed than the machine it replaced, the Sodick AD35L has eliminated a bottleneck and delivered important extra capacity to this progressive toolmaking specialist.

“Due to increasing order books we were encountering a bottleneck in our die-sink EDM processes,” states managing director Gary Statham. “We had an ageing machine that needed replacing, so the decision was taken to invest. Having had such good performance from our existing Sodick machines over the past five years, we decided to return to Sodi-Tech EDM.”
As luck would have it, soon after the AD35L had been installed, a significant order arrived from one of Neptune’s electrical industry customers for a series of six-cavity injection moulds. The tools are used to mould domestic plugs, sockets and switches for a major electrical brand.
“The timing could not have been better – as the new Sodick is at least 50% faster than the machine it replaced, we have been able to process the tooling much quicker,” says Statham. “Our new Sodick machine will be busy on this work for a number of months to come.”
Each mould tool and insert is complex, as plugs, sockets and switches typically contain features such as compound curvature, blended radii and freeform surfaces. The cavities and inserts produced by the new Sodick AD35L are all manufactured from tool steels such as H13 to tolerances within ±0.01 mm. Moreover, the company typically seeks a ‘zero finish’, essentially a polished surface which does not require any secondary operations; a factor that is readily accommodated by the AD35L.
