Capacity and Precision Upgraded: Centersky Electric Officially Commissions New High-Precision Silicon Steel Slitting Line

 

Jiangyin, China – July 3, 2026 — Jiangyin Centersky Electrical Appliance Co., Ltd has officially commissioned its new high-precision silicon steel slitting line following successful installation, commissioning, and performance verification. The new production line, developed through six months of investment and implementation, significantly enhances the company’s precision processing capabilities for electrical steel and strengthens its capacity to serve customers in the power transmission, renewable energy, and rail transportation industries with higher-quality silicon steel laminations.
As a national high-tech enterprise with more than 50 years of expertise in the research, development, and manufacturing of precision silicon steel laminations and magnetic cores, Centersky Electrical has consistently focused on technological innovation, process optimization, and intelligent manufacturing.

The newly commissioned slitting line represents another major milestone in the company’s continuous investment in advanced manufacturing technologies. From project planning and equipment selection to installation and commissioning, the entire project required approximately six months to complete. Throughout the implementation process, Centersky Electric’s engineering team worked closely with equipment suppliers, carrying out multiple rounds of technical optimization to address critical challenges associated with processing premium electrical steel, including slitting accuracy, surface protection, and residual stress control. These efforts resulted in substantial improvements in both equipment performance and manufacturing capability.

Designed to process a wide range of premium electrical steel grades and thicknesses, the new slitting line delivers micron-level dimensional accuracy while maintaining excellent edge quality. The processed laminations feature burr-free edges, minimal deformation, and significantly improved surface flatness, representing a 40% improvement over the previous production line. These enhancements help reduce magnetic losses during core stacking and improve the overall performance of finished magnetic cores by achieving lower core loss, greater dimensional stability, and enhanced operational reliability.

To further strengthen quality assurance, the production line is equipped with an intelligent online inspection system that continuously monitors strip dimensions and surface quality throughout the manufacturing process. Automated inspection minimizes the risk of human error and ensures consistent product quality, increasing the first-pass yield rate to more than 99.5%. The upgraded production capability also provides greater flexibility for manufacturing multiple product specifications in small production volumes, enabling the company to respond more efficiently to the growing demand for customized solutions.

According to the company’s production management team, demand for high-precision electrical steel slitting has increased significantly in recent years, particularly from customers in the renewable energy sector requiring customized dimensions and tighter manufacturing tolerances. Previously, production capacity and processing precision occasionally extended delivery times for these specialized orders. With the new production line now in operation, delivery efficiency for customized orders is expected to improve by approximately 35%. At the same time, optimized material utilization has significantly reduced production waste, while overall carbon emissions generated during manufacturing are expected to decrease by approximately 12%, further supporting the company’s commitment to intelligent, energy-efficient, and sustainable manufacturing.

In recent years, Centersky Electric has continuously invested in the modernization of its manufacturing facilities. Supported by nearly 12,000 square meters of intelligent production workshops, the company has established a fully integrated manufacturing system covering material selection, precision processing, heat treatment, insulation treatment, and comprehensive quality control. The commissioning of the new slitting line further strengthens this integrated manufacturing platform while providing additional support for the company’s dual production strategy of combining flexible customization with efficient large-scale manufacturing.
These enhanced capabilities enable Centersky Electric to provide more competitive magnetic core solutions for demanding applications, including power transmission and distribution equipment, wind power generation systems, photovoltaic inverters, electric vehicle drive motors, railway traction converters, and other high-performance electrical equipment where magnetic core quality directly influences efficiency and reliability.

Looking ahead, Centersky Electric will continue to leverage the commissioning of the new production line as an opportunity to further advance research into high-efficiency electrical steel processing technologies. Building upon more than five decades of manufacturing expertise, the company remains committed to continuous innovation, intelligent manufacturing, and precision engineering, contributing to the development of a more competitive, energy-efficient, and resilient electrical equipment industry both in China and worldwide.
