Record growth for EDM graphite & tooling specialists after £3.5million investment

Erodex UK Limited, the UK’s leading supplier of EDM graphite & tooling to the aerospace market, has experienced record levels of growth following a £3.5million investment and expansion into North America.

Overall turnover increased 20% during the last financial year, following previous record years for the firm. The growth has been a direct result of the investment, specifically targeted at work within the aerospace and industrial turbine sectors.

Director Steve Rolinson comments: “We have experienced significant growth on the tooling side of the business, which in fact is the fastest growing part of the Erodex group. The decision to invest in our own tool rooms and dedicated tooling inspection facilities has given us a real point of differentiation in the market. As well as designing the optimum electrode, the electrode holder and work piece holder, Erodex design and manufacture the whole package, all with a single point of contact. This is unique in our market and we are seeing more and more customers buying into this mindset because of cost and time savings”.

As well as picking up a number of new clients in China and Israel, the company have benefitted from their decision to establish a new £2million facility in Virginia, North America as well as investing £1.5million in a new UK tool room and machine shop. The decision to create a new UK tool room enables Erodex to produce their own tooling in house – particularly that with a significant amount of intellectual property. Doing so allows for tighter quality control, greater support and the carrying out of function trials by their own toolmakers prior to release.

Regarding the expansion into America, co-Director John Rolinson adds: “Rolls Royce Group announced that they were opening a new turbine blade facility in Virginia and Erodex were asked to support that as a result of our long term working relationship with them. This started off with us supplying graphite electrodes from the UK, however as their Virginia operation grew, we entered conversations about starting a tool room there so that we could offer the same fixture care and repair as well as inspection/trialling of tools in Virginia that we would do in the UK”.

To facilitate the growth, Erodex have expanded their workforce by 10% to above 100, taking on three experienced aerospace tool makers, a Tooling Manager, two Project Managers, Designers and more CNC operators. A Group Quality Manager and Group Quality Engineer were also recruited as part of a move towards AS9100 Rev D, ISO14001 and NADCAP Certifications.

Steve Rolinson adds: “The move towards AS9100 Rev D, ISO14001 and NADCAP Certification will allow further diversification of Erodex into flying parts. We currently make the electrodes required to make flying parts, but accreditation such as this will enable Erodex to handle and inspect flying parts ourselves, which is part of our longer term strategy for growth”.

Anti-Corrosion Powder

Erodex has recently launched its new Anti-Corrosion Powder that has been specially formulated to provide rust-prevention protection for water-based wire EDM machines. The innovative new powder-based additive has been developed to protect both the workpiece and the tank from oxidation. 

Rust occurs on steel parts as a result of a simple chemical reaction where positive ions from the steel workpiece dissolve in the water and react with oxygen molecules to form iron oxide on the surface of the workpiece, any steel fixturing and the machine’s work tank.

“Rust has plagued EDM shops for many years,” explains Erodex’s Sales Director, Steve Rolinson. “There has been limited success in addressing it without negative side-effects. In the past, liquid and powder chemical rust inhibitors have been used as additives to the dielectric fluid, but these inhibitors require monitoring to maintain concentration and can shorten the life of the de-ionising resin.”

Typically, existing anti-corrosion products require a concentration of 0.3 to 0.5 per cent by volume, and overdosing can affect the resin required to generate de-ionised water. Erodex’s powder can be easily managed using just a measuring cup. It is also cost-effective, requiring just 0.1 per cent to be added to the capacity of the tank; a 100g of powder will suffice for a 100 litre tank. The powder is supplied in compact 500g packs that are easy to handle and store. It is far less hazardous and more convenient than liquid as it weighs less and any accidental spillage can be easily gathered.

Erodex Anti-Corrosion Powder dissolves easily and homogeneously in the de-ionised water to disrupt the oxidation process in submerged parts. This eliminates any post process manual cleaning time, improving profits for extended cycle time wire EDM operations. It also keeps the machine and work station clean.

The powder does not affect the water de-ionising system, or the conductivity of the water. The solution is not sticky when dried which means that any sludge is easily remove, preventing secondary discharge.

“Using Erodex Anti-Corrosion Powder EDM workshops can virtually eliminate rust from long run-time wire EDM processes, providing manufacturers with significant improvements in long-term efficiency and profitability,” Steve Rolinson concludes.
