Sino: Lamination Stack Leaders in China
At Sino, we understand that the heart of any type of effective motor, transformer, or electromagnetic device beats stronger with precisely crafted core laminations. Our strength depends on a powerful mix of deep product proficiency– from picking the optimum grade of silicon steel, be it non-oriented or grain-oriented (GOES), to using remarkable insulation– and innovative production.
We’re discussing ultra-thin laminations, down to 0.1 mm for high-frequency scenarios, attained with precision marking or laser cutting, adhered to by stress-relieving annealing and careful setting up strategies like interlocking, bonding, or regulated welding.
Why choose Sino? Our track record speaks volumes. We have actually helped clients achieve substantial reductions in core losses– as an example, one industrial electric motor client saw a 4% decrease, leading to cooler operation and higher outcome. Our capacity to tailor lamination stacks to your precise specs, whether for basic E&I forms or complex, bespoke designs for EV grip motors or clinical gadgets, establishes us apart.

Sino's Precision Engineering
The number one reason for using lamination stacks is to slash those energy-sapping eddy current losses, and this is where Sino's attention to detail truly shines. The thinner the lamination, the more effectively we can suppress these currents, especially in high-frequency scenarios.
Lamination Core Manufacturer - Sino's Capability
We’re not a one-size-fits-all shop. For standard 50/60 Hz applications – think the motors in your workshop tools or neighborhood transformers – we typically produce core laminations with thicknesses from 0.35mm to 0.65mm.
But the modern world is demanding more. For instance, a client developing a cutting-edge, high-frequency switched-mode power supply for server farms approached us. Their design required minimal losses at much higher operating frequencies.
Sino rose to the challenge, engineering ultra-thin magnetic laminations down to 0.1mm, complete with a specialized high-resistivity insulation. The result? Their prototype exceeded efficiency targets, running cooler and more reliably than they’d hoped.
Laminated Core Insulation Integrity
That tiny layer of insulation is everything. Sino employs advanced coating techniques and rigorous quality checks to ensure there are no breaches or inconsistencies that could compromise the electrical separation between laminations.
Sino's Expertise in Electrical Steels
The metal itself is a critical piece of the puzzle. You can’t just use any old steel. Sino sources and works with specialized silicon steel (often called electrical steel) because its properties are tailor-made for lamination stacks.
Adding a small percentage of silicon (usually 1-4%) to iron works wonders: it significantly increases the steel’s electrical resistivity, further hindering those pesky eddy currents. It also helps to reduce another gremlin called hysteresis loss – the energy it takes to magnetize and demagnetize the core material with each AC cycle.
Sino's Material Portfolio
We understand that different scenarios demand different material grades.
Non-Oriented Electrical Steel
Perfect for devices where the magnetic field is constantly changing direction, like in the rotating parts of motors and generators. Sino ensures consistent quality for these dynamic applications.
Grain-Oriented Electrical Steel (GOES)
This stuff is special. It has superior magnetic properties along a specific grain direction achieved during its rolling process. This makes it the champion for transformer core laminations, where the magnetic flux generally follows a well-defined path. Sino can supply precisely cut GOES laminations that maximize transformer efficiency.
Data-Driven Decisions (Simplified Material Impact)
Material Property | Effect of Silicon (Si) in Steel | Sino’s Focus for Your Benefit |
Electrical Resistivity | Increases Significantly | Maximizes eddy current reduction |
Magnetic Permeability | Remains High | Ensures easy, efficient magnetization |
Coercivity | Decreases | Minimizes hysteresis energy loss |
Saturation Flux Density | Slight Decrease | Managed for optimal performance |
When you talk to Sino, we don’t just sell you steel; we discuss your application to help you select the optimal grade for your lamination stacks, ensuring you get the best performance-to-cost ratio.
How Sino Builds Superior Laminated Cores
Having the right material is one thing; shaping it and assembling it with precision is another. Sino’s manufacturing floor is a hub of advanced technology and skilled craftsmanship.
Precision Cutting
Whether it’s high-speed stamping for large volume orders of standard E&I core laminations, or intricate laser cutting for custom prototypes or complex motor stator/rotor shapes, Sino has the technology. We meticulously maintain our stamping dies to minimize burrs – those tiny metal whiskers that can pierce insulation and create shorts. For a recent project involving a uniquely shaped magnetic lamination for a medical imaging device, our laser cutting capabilities allowed the client to iterate through designs rapidly without incurring massive tooling costs.
Stress Relief (Annealing)
The process of stamping or cutting can introduce mechanical stresses into the steel, which can mess with its magnetic properties. Sino incorporates controlled annealing (heat treatment) processes to relieve these stresses, restoring the material to its optimal magnetic state. This ensures your laminated core performs as expected, not just looks the part.
Stacking & Joining with Integrity
How the individual lamination stacks are held together is crucial.
- Interlocking: A cost-effective mechanical method where small protrusions on one lamination lock into corresponding indentations on the next. Sino’s tooling ensures these interlocks are precise and secure.
- Bonding: Using specialized adhesives to glue the stack together. This can offer excellent insulation integrity, add mechanical rigidity, and even help with noise reduction. Sino has experience with various bonding agents suitable for different operating temperatures and stresses.
- Welding: While it needs to be done carefully to avoid creating localized shorts between laminations (which would defeat the purpose!), welding is often used for robustness, especially along the outer edges of a stack. Sino’s welding processes are tightly controlled to minimize any negative impact on inter-laminar resistance.
Maximizing the Stacking Factor
No stack is 100% dense metal due to the insulation layers and tiny air gaps. The “stacking factor” (typically 93-97%) tells you how much actual magnetic material you have. Sino strives to maximize this through precise coating thickness control and careful assembly, meaning you get more magnetic punch for a given stack volume.
Beyond the Basics: Sino's Customization for Your Unique Needs
The world of electromagnetics is diverse, and so are the requirements for lamination stacks. Sino isn’t just about standard parts; we thrive on customization.
Shapes and Sizes Galore
From common E, I, and UI shapes for transformers and inductors, to intricate toroidal (donut-shaped) laminated cores for high-performance power supplies, to fully custom-designed rotor and stator core laminations for specialized motors – if you can design it, Sino can likely figure out how to make it efficiently.

Real-World Scenarios: Where Sino's Lamination Stacks Power Progress
The applications for high-quality lamination stacks are virtually endless. Here are just a few scenarios where Sino's products make a critical difference:
Transformers
From massive power distribution transformers handling megawatts to the small ones in your phone charger, laminated cores (especially those from Sino using prime GOES) are essential for efficient voltage conversion with minimal energy loss.
Electric Motors
Every induction motor, brushless DC motor, or synchronous motor relies on precisely stacked core laminations for its stator and rotor. One automotive Tier 1 supplier worked with Sino to develop a new traction motor laminated core design that improved torque density by 7% through optimized slot geometry and material selection.
Generators
Whether it's a colossal generator in a hydroelectric dam or a wind turbine spinning atop a hill, efficient lamination stacks are key to converting mechanical energy into electrical energy with minimal losses.
Inductors and Chokes
In power electronics, these components are vital for conditioning power, and their performance hinges on the quality of their magnetic lamination based cores. Sino provides cores that ensure stable inductance and low losses in these demanding circuits.
