In modern power electronics, the demand for compact, highly efficient, and low-profile components has pushed traditional wire-wound magnetics to their physical limits. Flat Transformers (commonly referred to as Planar Transformers) represent a major evolutionary step, replacing conventional copper wire bobbins with layered PCB traces or flat copper foil windings. This unique construction minimizes leakage inductance, limits high-frequency skin effects, and offers an unmatched surface-area-to-volume ratio for superior thermal management.
As a leading supplier of manufacturing machinery and advanced magnetic components, Wuxi Shuhong Machinery Technology Co., Ltd. addresses the core challenges of modern power grids and high-frequency power supplies. By integrating precision engineering with state-of-the-art production systems, we enable global enterprises to source affordable, top-tier planar magnetic configurations tailored for telecommunications, consumer electronics, aerospace, and new energy vehicles (NEVs).
On the shores of the picturesque Taihu Lake lies Wuxi, known as the "Land of Fish and Rice." This beautiful land has nurtured countless enterprising enterprises, with Wuxi Shuhong Machinery Technology Co., Ltd. standing out among them. Since its establishment in 2018, Shuhong Machinery has consistently prioritized technological innovation and quality service, steadily advancing in the fields of electrical and plastic machinery, becoming a high-tech enterprise with both strength and reputation.
Our specialized production lines focus on the machinery that manufactures the next generation of power components. By engineering the winding, cutting, and welding apparatuses that make planar configurations possible, we serve as both a foundational machinery provider and a premium supply partner for global companies scaling their clean energy, aerospace, and grid infrastructures.
From frontline operations to technical leadership, our founder's journey shapes the core design philosophy of our power electronics and automation machinery.
Shuhong Machinery originated from its founder’s insight into machinery manufacturing. With over a decade in the industry, the founder witnessed domestic machinery shift from "following" to "running alongside" global peers, sensing the urgent need for energy-efficient, intelligent upgrades.
During a State Grid project exchange, the founder found traditional transformers flawed in temperature control and service life, noting new energy’s higher equipment demands—thus focusing on R&D of high-efficiency, energy-saving transformers.
Overcoming funding and technical hurdles, the team worked day and night in labs and workshops on demos and optimizations, finally developing a transformer with 30% lower temperature rise and a 15-year lifespan.
Our factory implements an rigorous production framework to guarantee that every flat transformer core and winding machine operates with zero defects. Planar magnetic integration requires high alignment accuracy, minimal dust interference, and specialized thermal encapsulation.
From raw silicon steel/amorphous alloy cutting to vacuum oil injection and comprehensive high-pot electrical testing, each step is monitored by automated PLCs to ensure our flat transformers perform consistently under harsh high-temperature conditions.
Focused on tech innovation, Wuxi Shuhong leads in insulation, temperature control, and automated assembly solutions. Our products have passed State Grid and international certifications, supplying over 2,000 substations globally.
Leveraging Wuxi's advanced industrial ecosystem to deliver premium performance at competitive prices.
Our factory is located in the heart of China's magnetic component manufacturing cluster. This yields instant access to premium raw materials like raw silicon steel sheets, high-frequency amorphous cores, and high-purity copper foils, keeping component costs remarkably low.
We design and manufacture our own foil winders and cutting systems. This allows us to scale production lines quickly and bypass external machine markup costs, enabling us to offer competitive wholesale pricing on custom builds.
With deep experience in State Grid and international compliance schemes, our products undergo automated visual inspection, magnetic field scanning, and long-term thermal cycle profiling to ensure extreme reliability.
Our flat transformers and specialized winding machinery are designed to support complex infrastructure layouts across multiple high-growth industries.
In automotive-grade applications, size and weight translate directly to vehicle range. Our flat transformers fit into low-profile On-Board Chargers (OBC) and DC-DC converters, yielding thermal stability under continuous rapid charging loads.
By utilizing amorphous alloy cores and precision triangular winding designs, we supply power distribution hubs with low-loss transformers that withstand grid overvoltages while sustaining stable operation.
Solar micro-inverters require high-frequency switching to convert DC solar generation to grid AC efficiently. Planar architectures provide low parasitic capacitance to achieve up to 99% conversion efficiency.
With AI servers pushing rack power requirements to 100kW+, space for power delivery is highly restricted. Our ultra-thin flat planar designs enable hyper-dense power supply units (PSUs) without compromising cooling airflow.
Procuring industrial electrical components on a global scale requires suppliers that possess both technical engineering capability and verified logistics frameworks. At Wuxi Shuhong, we align our engineering with standard international paradigms:
"We migrated our entire telecom power supply line to Wuxi Shuhong’s planar transformer manufacturing systems. The reduction in coil leakage inductance improved our overall system efficiency by 1.8%, while lowering our assembly reject rate to nearly zero."
Shuhong Machinery adheres to the team management philosophy of "People-Oriented, Collaborative Innovation", taking an excellent team as its success foundation. In talent development, it has a comprehensive training system for different positions and encourages employees to join industry technical exchanges.
By breaking departmental barriers with cross-departmental collaboration, using an advanced project management system, and holding regular team-building activities, we ensure our production lines and R&D divisions operate in absolute synergy.
Looking forward, Shuhong Machinery will uphold its business philosophy of "People-oriented, Integrity-driven, Collaborative Innovation, and Quality First." It will deepen focus on electrical and plastics machinery, boost R&D investment to strengthen core technologies, and launch more efficient, energy-saving and intelligent products.
