CRGO Lamination Stacks Manufacturer
And here at Sino, as a factory specializing in the manufacture of lamination stacks, we’re passionate about crafting CRGO laminations to the highest possible standard.
The Sino Touch: Why Our CRGO Laminations Make a Difference
At Sino, we don’t just buy CRGO steel and chop it up. We’re craftsmen (and women!) of the magnetic core. We understand that the journey from a roll of premium CRGO steel to a perfectly functioning crgo lamination core is paved with precision.
1
Ensuring every lamination is cut to exact dimensions, with clean edges to minimize burrs which can compromise insulation and increase losses.
2
Careful Handling
Preserving the delicate insulation coating on each lamination is paramount. Scratches or damage here can create short circuits between layers, undoing the whole point of laminating!
3
Whether it’s a simple stacked core or a more complex step-lap design for even lower losses and noise, the way the laminations are put together matters. We ensure tight, uniform stacking to maximize the amount of steel in the core (what’s called a high stacking factor) and maintain the integrity of the magnetic circuit.

Quality Materials
We start with high-grade CRGO steel, because you can’t make a silk purse from a sow’s ear, as the old saying goes.
Our CRGO Lamination Products
Unbeatable Low Core Loss: Saving Energy, Saving You Money
CRGO steel is engineered to have astonishingly low core losses. These losses come in two main flavors: Hysteresis Loss and Eddy Current Loss. While the raw CRGO material provides the foundation for low loss, our manufacturing process is crucial. By ensuring minimal burrs from cutting, preserving the integrity of the insulation coating (often a very thin layer of something like Carlite), and achieving a high stacking factor in the crgo lamination core, we help our customers squeeze every last bit of efficiency out of the material. This means transformers built with Sino laminations waste less energy as heat.
Riding the Magnetic Wave: High Permeability Thanks to Smart Grains
During its manufacture, the steel is cold-rolled and annealed in such a way that the crystal grains within the steel align preferentially in the rolling direction. This property is called high magnetic permeability. That means you need less “push” (magnetizing current) to get the desired amount of magnetic flux flowing through the core.
Sino’s Role: When we cut and assemble a crgo transformer lamination core, we pay meticulous attention to this grain orientation. For designs like mitred cores or step-lap cores, the angles and overlaps are precisely engineered to ensure the magnetic flux predominantly follows this easy path, minimizing “corner losses” where the flux has to turn. This isn’t just about cutting steel; it’s about understanding and respecting the physics of magnetism. Our precision ensures the final core behaves as the designer intended, maximizing that high permeability benefit.
Packing a Punch: High Saturation Flux Density
Every magnetic material has a limit to how much magnetic flux it can carry, a point called saturation. CRGO steel boasts a respectably high saturation flux density. That means you can design a core that carries the same amount of magnetic power using less actual steel.
Sino’s Flexibility: We work with various grades of CRGO steel, each with slightly different properties, including saturation flux density. By offering precisely manufactured CRGO laminations from the optimal grade for a specific design, we help engineers create more compact and cost-effective transformers without compromising performance.
Meeting Tomorrow's Demands: Energy Efficiency Standards
Around the globe, the whistle is blowing for greater energy efficiency. Lower-grade, non-oriented steels, or even poorly manufactured CRGO cores, simply can’t deliver the low-loss performance required.
Sino as Your Ally: By consistently delivering top-quality CRGO laminations and assembled crgo lamination cores that perform as expected, we provide a reliable foundation for building transformers that not only meet but often exceed these stringent efficiency benchmarks. When you choose Sino, you’re choosing a supplier committed to helping you build the efficient transformers of today and tomorrow.
The Sino Difference: More Than Just Steel, It's a Commitment
At Sino, we pride ourselves on being more than just a factory that cuts and stacks steel. We understand the nuances of CRGO laminations and their critical role in the performance of a crgo transformer lamination core.
Customization is Key
We know that one size rarely fits all. That's why we offer a wide range of customization options. Whether you need laminations for small single-phase transformers or massive three-phase power transformers, specific shapes (E&I, UI, toroidal, custom cut), mitred joints, step-lap configurations, or cores with precise gapping for inductor applications, Sino has the capability and expertise.
Insulation Integrity
The thin insulation coating on each lamination is its invisible shield. We employ careful handling and processing techniques to maintain the integrity of this coating, ensuring maximum resistance to eddy currents. Common coatings like C5 (Carlite) provide excellent insulation and withstand annealing temperatures.
State-of-the-Art Machinery
Our factory is equipped with advanced slitting lines, cutting machines (including CNC cutters for complex shapes), and stacking equipment. This allows for high precision, tight tolerances, and efficient production.
