STORY OF CLIENT

Boost Productivity with SIDA's Reliable Solutions

Plant Manager European Power Utility

"We integrated the automatic high-voltage winding machine and expandable winding mandrel into our line during a capacity expansion. Winding efficiency for large transformer coils improved by nearly 40%. The tension control is precise and consistent, and our first-pass yield rate has climbed noticeably. Technical support responds within a day, which keeps our schedule on track."

Senior Process Engineer Southeast Asian Transformer OEM

"The servo sorting core cutting line has become a critical part of our silicon-steel processing shop. Edge quality is clean and burr-free, and the automated sorting reduces manual handling significantly. Over six months of continuous running, the repeatability has held up well, which matters a lot for our stacked-core tolerance specs."

Purchasing Director Designation

"Since adding the CNC step-pad block machining center and the multi-layer heat press, we have brought most insulation-part fabrication in-house. Parts we used to outsource with a two-week lead time are now finished in about three days. The machining accuracy and lamination pressure uniformity meet IEC-grade requirements without issue."

Maintenance Supervisor Middle East Electrical Infrastructure Contractor

"We run the vacuum drying equipment in tandem with the HB-series curing oven for large transformer coils. Temperature distribution is even across the chamber, and the HA-series energy-saving dipping-paint drying oven has made a visible dent in our monthly power consumption. The control interface is straightforward for our operators to manage batch recipes."

General Manager — General Manager,

"The equipment lineup—from foil winding machines and core stacking tables to coil presses and drying ovens—interfaces well as a system. Commissioning support was hands-on: their technicians supervised mechanical alignment, ran trial batches with us, and trained our staff on daily calibration. It felt like a partnership rather than a one-off sale."
