Let Sino's Lamination Stacks Empower Your Project!

To speed up your project, you can label Lamination Stacks with details such as tolerance, material, surface finish, whether or not oxidized insulation is required, quantity, and more.

EI Core Lamination Stacks Manufacturer

Here at Sino, we don’t just make EI core laminations; we craft them. We understand that the performance of your final product – be it a transformer, an inductor, or a motor – hinges significantly on the quality of the magnetic core. That’s why we’re meticulous about every step.

How Sino's Laminations Tackle Energy Waste

At Sino, we offer EI laminations in a variety of standard thicknesses – from 0.35mm (often designated as M36 or similar) to 0.5mm (like M47) and even thinner for specialized needs – allowing you to balance cost against efficiency requirements. We ensure that the insulating coating applied to our steel, or inherent in its mill processing, maintains its integrity even after stamping and stacking. This focus on insulation integrity is critical for an efficient ei transformer core.

Where Sino's EI Cores Make a Difference

Everyday Gadgets Powering

Everyday Gadgets Powering

Sino supplies laminations to manufacturers who build compact, efficient power supplies for phones or laptops by the millions. Our consistent quality means their automated assembly lines run smoothly, and the end products are reliable.

Industrial Controls

Industrial Controls

Control panels for machinery, automation systems, and industrial power supplies often rely on robust transformers and inductors built with EI core laminations. These environments can be demanding, with temperature fluctuations and electrical noise. Sino’s durable laminations, built from appropriately graded steel, ensure that these critical components keep running day in and day out.

Audio Applications

Audio Applications

Many excellent audio amplifiers, pre-amplifiers, and power conditioners utilize transformers with EI laminations for their power supplies or as output transformers. The consistent stacking and low-loss characteristics of Sino’s laminations help minimize hum and distortion, contributing to a better listening experience.

Lighting System

Lighting System

From traditional fluorescent ballast transformers to certain types of LED driver transformers, EI laminations have played a role. Sino has worked with lighting manufacturers to provide custom ei core lamination stacks that meet specific size and efficiency targets.

Renewable Energy Components

Renewable Energy Components

Even in the burgeoning field of renewable energy, components like grid-tie inverters or charge controllers sometimes utilize transformers or inductors based on EI core lamination designs for certain auxiliary power or filtering functions, especially where cost and reliability are key drivers. Sino is actively exploring these scenarios with innovators in the green tech space.

The Sino Material Palette: Choosing the Right Steel

The heart of any EI core lamination is the electrical steel. The silicon content (typically a few percent) increases the electrical resistivity of the steel, which helps to reduce eddy current losses.

At Sino, we don’t just stamp steel; we partner with you to select the optimal grade and thickness for your specific scenario. Our technical team can discuss your operating frequency, flux density, efficiency targets, and cost constraints to recommend the most suitable material for your ei transformer core or inductor. We source our steel from reputable mills, ensuring consistent quality and adherence to international standards, which is a cornerstone of our product quality.

Here’s a quick rundown of common material types Sino works with, and their typical deployment:

Lamination Material Type

Key Characteristics

Typical Scenarios

Grain-Oriented Silicon Steel (GOSS)

Highest permeability in the rolling direction, very low core loss. More expensive.

High-efficiency power transformers, distribution transformers, premium audio transformers.

Non-Oriented Silicon Steel (e.g., M36, M47, etc.)

Uniform magnetic properties in all directions. Good balance of cost and performance.

General purpose transformers, motors, generators, chokes, ballasts, appliance transformers.

Thinner Gauge Non-Oriented Steel (e.g., 0.2mm, 0.35mm)

Lower eddy current losses at higher frequencies than standard 0.5mm.

Higher frequency transformers (up to a few kHz), some SMPS applications, specialized motors.

Nickel-Iron Alloys (e.g., MuMetal, Permalloy – on request)

Extremely high permeability at low field strengths, excellent for shielding.

Very sensitive audio transformers, magnetic shielding, precision current sensors (less common for standard EI laminations but possible for custom projects).
