Support underpins success


RST Engineering, which currently has six Sodick EDM machines on site at its manufacturing facility in Leighton Buzzard, reports that 2022/23 was the best year in the company’s history. The business bases this success not just on its commitment to ongoing investment in the latest Sodick machines, but in the back-up and support of exclusive UK distributor Sodi-Tech EDM.

 Robert and Maureen Taylor founded RST Engineering in 1986. Today, sons Jason, Sean and Paul help ensure the company continues to foster its reputation as a progressive and ambitious precision engineering business, and with good effect. RST bounced back strongly following the pandemic, during which the company invested in two Sodick machines: an ALC600G high-precision wire EDM with linear motors; and an AG80L die-sink EDM, the largest spark-erosion machine in their Sodick portfolio.

“We continue to invest in new Sodick machines because they play a big part in our success,” states Director Jason Taylor.

The 15-employee company serves numerous manufacturing sectors, but has a strong track record in scientific research and satellite communications.

“We currently have a scientific contract that runs continuously – 24/7 – on two of our Sodick wire EDMs, producing 1250 parts a week with tolerances down to 10µm,” explains Mr Taylor. “Hundreds of wire threads are required for each batch, and with the back-up of consumables, spares and service from Sodi-Tech, the project runs flawlessly.”

The contract involves the manufacturing of two delicate mating components made from 316 stainless steel. One measures just 10mm x 2mm. To keep the machines running continuously, RST Engineering relies on the wire, filters and resin consumables supplied by Sodi-Tech EDM.

“Sodi-Tech EDM has a huge stock of spare parts and consumables at its Warwick headquarters for all machines, and we always receive very prompt delivery,” states Mr Taylor.

RST Engineering runs six Sodick machines, three die-sink and three wire models. The company is currently considering trading in one of its older wire machines for another ALC600G.

“At the weekend we set it going on Friday and it runs unattended until Sunday night with no unexpected stoppages,” says Mr Taylor. “Our approach is to set-up a double block of material, wiring in two directions to end up with 60 components per block.”

The company’s other recent investment is a Sodick AG80L die-sink machine which, with its 32-station toolchanger, was bought specifically for a project involving the manufacture of a satellite communications component. In total, RST Engineering had to produce 100 very large parts. Loading four at a time, each component required around 50 hours of spark erosion.

“As a project it ran seamlessly,” reports Mr Taylor. “In general, our investment in machining and inspection equipment always delivers an increase in accuracy, capacity and machining speeds, allowing us to keep up with demand for sophisticated parts like those for satellite communications systems, which are high in complexity and precision”

Of course, with so much non-stop machining to incredibly high levels of precision, the law of averages says that sometimes there will be a setback. However, when this rare situation arises, Sodi-Tech EDM is always on hand.
