FREQUENTLY ASKED QUESTIONS
Our EI silicon steel sheets are key materials for manufacturing cores of various transformers, reactors, motors, and generators. Specific applications include:
Transformers: such as power transformers, audio transformers, voltage stabilizers, etc. Inductor: Used in filters and energy storage devices.
Motors and generators: As part of the magnetic core, they enhance equipment performance.
Electronic devices: such as switching power supplies, inverters, and other equipment requiring stable magnetic properties.
Choosing our EI silicon steel laminations offers you the following advantages:
Efficient magnetic circuit: The combination of E-shaped and I-shaped laminations forms a closed magnetic path, effectively reducing magnetic flux leakage and losses.
Low hysteresis loss: Utilizing high-quality silicon steel material significantly reduces hysteresis loss and improves overall energy efficiency.
Easy to manufacture: simple structural design facilitates mass production and automated assembly.
Affordable: Advanced manufacturing techniques and optimized material costs offer you a high-value solution.
Stable performance: With over 15 years of manufacturing experience, we ensure reliable and consistent product performance.
Of course. We understand that different customers have varying needs, so we offer comprehensive customized services.
Custom sizing: In addition to standard sizes, we can produce EI laminations in specific dimensions based on your drawings or samples.
Material Customization: Based on your product application, service life, and operating environment, werecommend or select the most suitable silicon steel material for you.
One-stop service: We offer comprehensive solutions from design and production to packaging, meeting your OEM/ODM requirements.
Quality is our lifeline. We have established a rigorous quality control system to ensure that every product meets the required standards.
System Certification: Our quality management system has been certified under ISO 9001:2015, covering the entire process from raw materials to finished product delivery.
Full-process quality inspection:
Raw material inspection: Conduct width, thickness, and iron loss tests on every incoming coil of silicon steel.
In-process sampling inspection: During the stamping production process, random sampling checks are conducted on EI laminations.
Pre-shipment inspection: Random box inspections are conducted before shipment to ensure the products are undamaged.
We primarily produce grain-oriented silicon steel sheets and can provide products of various grades according to customer requirements.
Non-oriented silicon steel: grains are randomly distributed, suitable for manufacturing rotating equipment such as motors and generators.
Grain-oriented silicon steel: exhibits extremely low iron loss and high permeability in the rolling direction, suitable for manufacturing static equipment such as transformers.
Main components: Our silicon steel sheets are primarily composed of iron (Fe) and silicon (Si), and contain trace amounts of chromium (Cr), manganese (Mn), and other elements to optimize performance.
