Jiangsu Hongyun Precision Industry Co., Ltd. is a National High-Tech Enterprise and a Jiangsu Provincial Specialized, Refined, Distinctive, and Innovative SME. We focus on the R&D and manufacturing of permalloy-series magnetic components, specializing in the production of transformer cores, laminations, shielding cases, and related products. These are widely used in high-end manufacturing fields such as semiconductors, sensors, and precision electronics.
With permalloy materials and related products at our core, our products fall into four major series:
1. Lamination Series: Covering EI, EE, ED/EL, UI, and UM laminations in a wide range of specifications, mainly made of PC (approximately 80% nickel) and PB (48%–50% nickel) materials, with standard thicknesses of 0.15 mm, 0.2 mm, and 0.35 mm. These are primarily used in precision transformers, audio transformers, common-mode inductors, etc.
2. Core Series: Including wound cores, stacked riveted cores, cut cores, toroidal lamination cores, etc., mainly used in transformers, common-mode inductors, power transformers, among others.
3. Shielding Series and Precision Structural Components: Including shielding cases, shielding cylinders, shielding covers, and shielding sheets, as well as precision sheet metal parts, non-standard enclosures, and semiconductor equipment chambers. These mainly serve semiconductor equipment and demanding electromagnetic shielding applications. We also provide technical services such as magnetic performance optimization, shielding structure process adaptation, and customized heat treatment.
4. Raw Material Series: Providing raw materials in various forms including strip, rod, wire, and sheet, mainly used for the subsequent processing of electronic components, sensors, and shielding assemblies.
We have established a municipal Enterprise Technology Center and have been granted more than 30 patents. We possess in-house capabilities in material modification, precision stamping, and custom development. We have passed ISO 9001, ISO 14001, and IATF 16949 certifications and have built an end-to-end quality control system. We are also capable of supplying magnetic shielding structural components for semiconductor equipment and soft magnetic components for power supplies. We can handle customized orders with multiple specifications, small batches, and rapid delivery, with an annual production capacity of approximately 200 tons, providing customers with full-cycle technical support.
In the future, we will honor our customers' trust and support with an even more enterprising spirit, continuously enhancing our technological R&D and precision manufacturing capabilities, creating value for our customers, and achieving win-win development.
