Who we are

From Coil to Core Turnkey Iron‑Core Automation

We build production systems that help transformer and motor manufacturers make iron cores with consistent quality at scale.

By combining process engineering, automation, and line integration, we reduce manual dependence and make performance repeatable—shift after shift, product after product.

The goal is simple: higher OEE, lower variability, and a line you can trust.

Technology Behind Our Transformer Core Lines

Low‑Burr Slitting

Rigid knife stands, controlled tension and precise settings help you achieve consistently low burr levels.

High-speed cut to length

High-stroke cutting sections and stable feeding help you increase laminations per minute.

Flexible V‑Notching and Punching

Configurable notching and punching heads support different step-lap patterns and window designs.

Automatic Stacking Systems

We have two stacking solutions: integrated robot arms for in-line assembly and dedicated machines for high-volume production.

Transformer Cores We Focus On

Core programs & production scenarios

Transformer performance starts with lamination consistency. We design silicon‑steel processing and automation solutions for manufacturers who need repeatable core quality—stable edge condition, predictable geometry, and clean stacking—so results stay consistent from the first batch to long‑run production.

From slitting and cut‑to‑length/punching to automated stacking and line integration, we engineer each project around your core design and takt time. The goal is simple: higher efficiency, tighter precision, and lower total operating cost—without relying on constant manual adjustment.

Key Elements of a Reliable Core Line

Precision

Low‑burr cutting and stable tolerances help laminations stack cleanly and keep core quality consistent across shifts and operators.

Efficiency

High‑throughput processing and automation reduce bottlenecks, improve OEE, and shorten changeovers—so output scales without scaling labor.

Reliability

In‑house core components, remote diagnostics, and turnkey responsibility reduce downtime risk and protect long‑term performance after installation.
