There're three methods of manufacturing silicon steel transformer cores: stamping, wire cutting and laser cutting. Stamping Stamping is generally used for producing large quantities of identical metal components through a stamping press. Steel sheet is placed on a stamping press and then it’s positioned and stamped through a die set. Stamping is a more versatile manufacturing process because it can be used for both short and long run production. Stamping sheet is one of the most frequently adapted products. Advantages: - Cost-effective - High accuracy and precision - Produces high-quality output - Suitable for large volume production Disadvantages: - Not suitable for creating intricate designs - Expensive die design Stamping is a widely popular manufacturing process used in areas such as: Automotive, Construction, Aerospace and Electronics.   Stamping machine   Stamping sheet and stamping lamination samples   Wire Cutting Wire Cutting is a manufacturing process that uses a thin wire to precisely cut a work piece into a specific shape. The process involves using a thin metal wire, that is electrically charged, to cut through a work piece of the material.   Advantages: - High accuracy and precision - Can cut through thick materials - Suitable for creating intricate designs Disadvantages of Wire Cutting: - Expensive equipment - Limited to certain types of materials Wire Cutting is used in making a varied range of products including medical devices, aerospace parts, and precision machine components.     Wire cutting machine   Laser Cutting Laser Cutting is a modern manufacturing process that uses a laser beam to cut through materials.  The laser beam is generated by a laser tube inside a laser cutting machine.   Advantages: - Accurate and precise cutting - More energy efficient - Clean cutting edges - Less material waste Disadvantages: - Expensive equipment - Limited to certain types of materials Laser cutting is used in various industries including Aerospace, Architecture, Shop signage, and Metal fabrication.     Laser cutting machine   Laser cutting transformer cores samples   Both ways are available for silicon steel transformer cores manufacturing, there're still several differences between wire cutting and laser cutting: 1. The processes are different. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reaches the ignition point, and at the same time, the molten material is blown away by the high-speed airflow coaxial with the beam, so as to achieve the workpiece cut open. While wire cutting relies on the pulse electric spark discharge between the electrode wire and the workpiece, which generates high temperature to melt or vaporize the metal. 2. Different features for their products. After the material is laser cut, the width of the heat-affected zone is very small, and the properties of the material near the slit are almost unaffected, and the deformation of the workpiece is small, the cutting precision is high, the geometry of the slit is good, and the cross-sectional shape of the slit is relatively smooth. Wire cutting directly uses 0.03-0.35mm metal wire as the electrode, which does not require a specific shape, which can save the design and manufacturing costs of the electrode; regardless of the hardness of the workpiece material, as long as it is a conductor or semiconductor material, it can be processed, and the loss of the electrode wire is small, and the processing High precision; suitable for processing small batches, parts with complex shapes, single pieces and trial products, and the processing cycle is short. 3. They are for different applications. As a precision processing method, laser cutting can cut almost all materials, including two-dimensional cutting or three-dimensional cutting of thin metal plates. Wire cutting is widely used for processing molds; processing parts with fine structures; processing parts with complex shapes; processing hard conductive materials; trial production of new products; blanking of precious metals.     In summary, each manufacturing process has its unique advantages and disadvantages, and it mainly depends on the specific application requirements to determine which process is the best suit. For CRNGO or CRGO silicon steel semi-products, professional customization and sourcing services are provided by Shunge Steel.

Steel Laminations are mainly used in producing: – rotors & stators for electrical motors – transformer cores – motor cores – generator cores – magnetic cores – Industrial equipment...   Silicon steel laminations are generally produced by stamping or wire erosion, then the sheets are laminated and stacked to required height based on customized designs. Besides the two methods above, Shunge Steel has professional production lines using fiber laser numerical control processing equipment for laser cutting cores.     The laser cutting facilities work based on demanding applications and has multiple advantages: – Cut into arbitrary graphics - including complex, small-batch but multi-variety, diverse products – Shorten the motor R&D procedures and lead time: new samples could be produced quickly after the product drawing is formed. – Cut silicon steel coil accurately to customized specifications – Surface of laser cutting core is flat and smooth: free of flaws such as burr, cracking, deformation, or collapse... – Save cost and time of mold   – Appliable for different silicon steel raw materials: Suitable for various steel grades, regardless of hardness.     Despite of stamping or wire erosion, laser cutting technology now has become a promising method of producing specially customized core designs for many domestic customers. To date we’ve provided laser cutting cores for local motor manufacturers, transformer manufacturers, home appliance industries, industrial device manufacturers, etc. Could contact us and send over your design for laser cutting core, more datas and specifications are also needed, we'll see to it and see if we could work together. 

The exceptional performance of cores relies on high-quality prime electrical steel raw materials and an advanced manufacturing system. Shunge Steel employs professional production lines equipped with precise high-speed mold punching machines to stamp the sheets, ensuring optimal results. Electrical steel from leading or private steel mills Through extensive testing and adjustments, we have achieved the capability to process stamping sheets within a thickness range of 0.1-1.0mm. Our cutting precision tolerance is tightly controlled, with a deviation of only ±0.01mm.   Customized steel sheet based on customer's drawing of design Our mold punching process offers several advantages, including high guiding precision, stable punching performance, uniform blanking clearance, and extended service life. To support our production needs, we currently operate 8 one-go punching machines and 10 high-speed punching machines. These machines, combined with rigorous quality checks, enable us to maintain high quality standards and ensure fast production lead times.   One-go punching production line   High-speed punching production line      Mature quality check system Over time, we have established successful partnerships with nearly 200 motor companies. Our expertise lies in solving production and processing challenges that demand diverse product varieties, small-batch production, and customized non-standard sheet R&D.   Regular stamping sheet product demonstration If you would like to customize silicon steel sheet for own transformer core, motor core, stator and so on, it would be really helpful when more specifications and datas are provided: Specification of material Drawing of design Required Quantity Production technique Production lead time Required certificates of import
