Hunan Qianhao Electromechanical Technology Development Co., Ltd.

Injection molding process

Qianhao Magnetic Electric's permanent magnet technology deeply empowers the innovation of injection molding processes. By reconstructing the rapid mold change system with magnetic templates, it achieves millisecond adsorption response and micrometer positioning accuracy. It is compatible with global mainstream injection molding machine brands such as Haitian, Zhenxiong, Yizumi, Fanuc, Sumitomo, Toshiba, Nissei, Engel, and KraussMaffei, constructing a cross-model standardized solution. In the home appliance field, it helps Midea, Gree, and Haier achieve second-level mold switching, reducing downtime by more than 500 hours per year for a single device. In the automotive manufacturing sector, it provides magnetic quick-change systems for BYD, Tesla, and Continental Group, increasing the efficiency of large mold changes for bumpers, door panels, and other parts by 80%. Furthermore, it collaborates with industrial giants such as Bosch, Siemens, and Foxconn to build intelligent production lines, driving injection molding factories towards the "zero downtime" goal with zero-loss magnetic control technology and reshaping the global plastic processing industry efficiency benchmark.

Intelligent lifting tools for steel plants

Steel plate lifting

Taking Liugang as an example, Qianhao's electro-permanent magnetic lifter can lift 8 steel plates and accurately place one, requiring only one person to operate the remote control, ensuring personnel safety.

Intelligent lifting tools for steel plants

Silicon steel lifting

Taking Wuhan Iron and Steel as an example, facing the uneven surface of vertically placed silicon steel, Qianhao's experiment can lift 20 tons of vertically placed silicon steel with 2mm thick wooden boards.

Lifting

Steel pipe lifting

Taking Tianjin Steel Pipe as an example, in order to solve the high-efficiency requirements of loading, unloading, and stacking, Qianhao magnetic electricity designed an electro-permanent magnetic lifter that can not only lift bundles of steel pipes but also rows of steel pipes.

Production lines of engineering machinery manufacturing enterprises

Manufacturing of various engineering machinery equipment

In the production lines of cranes, road rollers, excavators, bulldozers, etc., from the warehousing and lifting of steel plates to the loading and unloading of laser cutting, to sorting and stacking, and welding, Qianhao magnetic electricity has mature and配套的 electro-permanent magnetic iron equipment to solve them one by one.

Industry application fields

Steel material logistics park

Such as Hunan Yili Logistics, thanks to the precise adsorption and stacking of electro-permanent magnets, the entire logistics park uses electro-permanent magnetic equipment for the handling and sorting of steel materials. Its efficient and precise adsorption capacity reduces manual handling errors, improves logistics efficiency, and enhances personnel safety.

Steel structure processing

In steel structure processing, Qianhao electro-permanent magnets are widely used. In the cutting process, it can quickly fix the steel plate to prevent displacement; during welding, it can accurately position the components to ensure welding accuracy; in the assembly stage, it helps to hoist and connect large steel components, improving processing efficiency and quality.

Industry pain points

Low efficiency of manual hoisting

Unable to ensure personal safety
High labor cost input and low efficiency

Traditional hoisting equipment is backward

Vacuum suction cups have poor adaptability
Grippers and clamps easily damage workpieces

High energy consumption

Electro-permanent magnets are 95% more energy-efficient than electromagnets
Taking a steel plant as an example, it can save 200,000 yuan a year (taking Liugang as an example)

Solution

20-ton port electric permanent magnet lifting device

In modern port logistics systems, the efficiency and safety of steel plate handling directly affect overall operational efficiency. Qianhao Magnetic Electric's 20-ton electro-permanent magnetic lifting device, developed specifically for port scenarios, provides a revolutionary solution for gantry crane operations, leveraging its intelligent magnetic adjustment system and six-fold safety protection technology.

Steel plate lifting devices of a certain steel structure plant

Qianhao electric permanent magnet lifting tools have been widely recognized and repurchased by customers for lifting steel plates, steel pipes, cast iron pipes and other ferromagnetic workpieces. When using electric permanent magnet lifting tools to lift steel pipes and cast iron pipes (round ferromagnetic workpieces), only a portion of the contact surface needs to be attached to lift 8 tons, 10 tons, 16 tons, and 32 tons.
