Stirling-based CA Models, a specialist in high-quality, fast-turnaround metal and plastic additive manufacturing, is using new investment in two wire-erosion machines from Sodi-Tech EDM to optimise the process of removing 3D-printed parts from their build platforms.

“We had two Sodick wire EDM machines that were still running well but getting on in years,” explains founder and managing director Clark Campbell. “I felt it was the right time to bring in some new technology for the next decade. The new Sodick machines are even more accurate and faster. At CA Models we are in the ‘quick’ business, where just about every client wants their parts yesterday. That’s why we need an in-house resource when it comes to wire erosion. Every time we have a really complex, accurate part to produce, the clock is ticking.”

He adds: “I think Sodick technology is brilliant and the reliability of the machines warrants some loyalty in my opinion,” says Mr Campbell. “I went to an open day at Sodi-Tech EDM’s Warwick facility and was really impressed with the latest machines, which will play their part in a big way over the coming years.”

Installed in September 2022, the new Sodick ALC600G and ALC800G wire EDM machines are already busy.

“For example, take a titanium build platform with 14 motorsport parts on the base,” says Mr Campbell. “When the printing process is complete, the entire platform goes into our furnace for heat treatment for 24 hours, after which we wire-off all the components from base plate using our Sodick technology. As the wire cuts so finely we do not lose any dimensional accuracy in the parts. Furthermore, the machines wire so quickly that we get a head start in finishing the components.”
