Product introduction
This product utilizes the latest bending fittings, which feature minimal components, high processing accuracy, precise positioning, easy assembly, and simplified surface treatment and painting processes.
Product Features:
1.The silicon steel sheets are processed using advanced intelligent production lines, resulting in high processing accuracy, minimal burrs, and high efficiency.
2.Emphasis on craftsmanship reduces external stress on the silicon steel throughout the entire process from raw materials to finished products, lowering the manufacturing process coefficient of the iron core and effectively ensuring product performance and quality.
3.Full sequence laminating method is adopted, offering three, five, or seven-step laminating processes based on different material and product requirements to provide differentiated solutions for customers.
4.High-strength steel is used for the fittings, and different steel materials can be provided based on customer requirements. CNC bending ensures high mechanical strength, precise dimensional positioning, and a sleek and aesthetically pleasing appearance.
5.The core column and lower yoke are secured using brushing and painting processes, enhancing the mechanical performance of the iron core. The materials used are environmentally friendly, safe, and free from irritating odors.
