SMD Inductors T-Core Seires

Since 2013, Dongguan Donghong Automation Technology Co., Ltd. has been deeply engaged in the field of inductor intelligent manufacturing for twelve years. With its fully self - developed technical strength, the company has successfully redefined the production standards for integrated molded inductors. Through in - depth research on the compression characteristics of magnetic powder, the mechanics of precise winding, and the models of hot - pressing conduction, the SMD Inductors T-Core Seires of equipment integrates three core technical genes: precise mechanical control ensures a powder molding accuracy of ±0.01mm and a winding tension fluctuation of less than 0.3%; the closed - loop process chain design covers 8 major processes, increasing the first - pass yield to 98.5%; and the native Industry 4.0 architecture ensures that all equipment supports OPC UA/ETHERCAT protocols.

The powder molding machine adopts static mold pressing technology. By applying pressure unidirectionally from the upper mold while keeping the lower mold fixed, it completely eliminates the displacement errors of traditional double - action molds. The intelligent control system is equipped with an electronic ruler to monitor the pressing position in real - time with an accuracy of ±0.01mm, and achieves three - in - one linkage of automatic product ejection, automatic filling, and automatic detection. The optimized hydraulic system uses a proportional valve to adjust the pressure and flow steplessly. Combined with the master - slave oil cylinders, it realizes fast descent and slow pressing, with an operating noise of less than 60dB. The 7 - inch multi - language touch screen supports operation in Chinese, English, and Russian, and is equipped with a fault self - diagnosis system, greatly enhancing operational convenience and equipment stability.

The flat - wire winding machine (U - CORE) demonstrates strong compatibility, adapting to the full range of 1608 - 04 inductor sizes and enabling rapid model change within 10 minutes. Its self - adaptive tension system automatically adjusts the winding force through core components, maintaining a stable production yield of 99.2%. The round - wire winding machine (T - CORE) covers the entire size range, supporting the production of 0201 - 2520 specification inductors. With the AI - assisted winding path, it optimizes the copper wire trajectory through machine learning, effectively reducing the wire breakage rate by 80%.

The integrated implant hot - pressing machine achieves dual technical breakthroughs. The anti - powder leakage technology reduces 90% of powder leakage through a pre - pressing device and uses a displacement sensor with an accuracy of ±1μm for real - time monitoring. The four - stage pressure control adopts a gradient pressure application of 20N→50N→80N→30N, increasing the utilization rate of magnetic powder by 30%. The dual - axis laser paint stripping machine is renowned for its precision processing. The coordinated operation of the dual axes achieves a paint stripping accuracy of ±3μm, and the low - temperature process ensures that the working temperature rise is less than 5°C, causing zero damage to the magnetic core.

The indexing disc testing and packaging machine focuses on high - speed operation and intelligence. With a transfer efficiency of 0.8 seconds per piece, it outperforms Japanese equipment by 40%. The AI visual inspection system, equipped with deep learning algorithms, controls the false non - detection rate at 0.01%. It also supports rapid model change for more than 20 types of products within 10 minutes.

The entire T - CORE series of equipment has remarkable core advantages. In terms of stability, one operator can easily manage 8 devices. In cost control, the selling price is only 50% of that of European and American brands and 70% of Japanese brands. With strong quality assurance, the yield rate of key processes is ≥99%. The technology is completely independent, with 100% independent research and development of the mechanical structure and control system. The company provides considerate services, including free lifetime software upgrades and hardware maintenance at cost price. Having operated without major accidents for 12 years and served more than 2,000 customers, it has full market credibility.
