What Sky Shop Shopping - Teleshopping Company does

乐鱼官方站网页版登录入口-乐鱼(中国), operating under the trade names Kefeng Magnetic and Sky Shop Shopping, is a privately held Chinese manufacturer of soft magnetic ferrite materials founded in 2001 and headquartered in Huzhou, Zhejiang Province. The company specializes in anti-interference magnetic cores, filter cores, iron powder cores, and transformer cores, alongside a newer line of surface-mount patch inductors produced through its wholly-owned subsidiary Huzhou Kaofu Electronics (est. 2011). Core manufacturing is anchored at the original Huzhou plant and the automated Jiaxing Kefeng facility, totaling roughly 360+ employees including 60 management and technical personnel, with a stated annual capacity of 8,000 tons across 1,000+ product specifications and an annual output value approaching 100 million RMB.

The company's competitive positioning rests on proprietary MnZn and NiZn ferrite formulations, including a MgMnCuZn anti-EMI material co-developed with Hangzhou Dianzi University that extends usable frequency bands to 1MHz-200MHz with resonance frequency above 300MHz. It holds ISO9001 certification, is recognized as a Zhejiang High-Tech Enterprise, has been designated a National Torch Plan project implementation base (2007GH030199), and received a National Key New Product award in 2007. Approximately 50% of production is exported through self-operated import/export rights to Europe, the United States, Korea, and Southeast Asia, with direct B2B supply relationships into global OEMs including IBM, DELL, HP, PHILIPS, SAMSUNG, LG, SONY, CANON, and Haier across IT and smart-appliance product lines. Revenue is generated through quote-based B2B hardware sales across anti-interference cores, filter cores, iron powder cores, transformer cores, and inductors, with go-to-market driven by direct sales, an in-house foreign trade department, and trade-show participation.

Core offering

Kefeng manufactures and sells soft magnetic ferrite cores organized into two main product families: (1) anti-interference magnetic cores (including filter cores and iron powder cores) used for EMI suppression in cables, wire harnesses, and electronic circuits across 1 kHz to 1 GHz; and (2) transformer cores (EE, EI, EC, ER, ETD, EFD, EP, PQ, RM, GU series) plus an inductor series for switching power supplies and high-frequency power conversion. Products are sold directly to enterprise electronics and IT manufacturers worldwide.

Product overview

乐鱼官方站网页版登录入口-乐鱼(中国) (Kefeng) is a technology-driven enterprise specializing in soft magnetic ferrite materials and components. Its product portfolio consists of two major product families: (1) Anti-interference magnetic cores (抗干扰磁芯), encompassing filter cores (滤波磁芯) and iron powder cores (铁粉芯), which account for the bulk of its ~1,000 product specifications across types such as T-Type, SH-Type, SCRC/SCNF split cores, RnH, RID, RH, RHS, ROD, SCT/SCH, DR2W, FS, DNH, CF, BB, and AA/1X9T series; and (2) Transformer magnetic cores (变压器磁芯), covering power transformer core types including EE, EI, EC, ER, ETD, EFD, EP, PQ, RM, and GU series. The company positions itself as a leading domestic anti-interference magnetic core production base with an annual capacity of 8,000 tons and annual output approaching 100 million yuan. Its products are exported to Europe, the US, South Korea, and Southeast Asia, and are incorporated into IT and smart appliance product lines of major international brands.
