　　The servo powder‑forming machine is a new type of dedicated, all‑servo equipment. It uses a servo motor to drive the screw rotation, as well as the upper and lower punches and their vertical movement, enabling precise powder compaction. Featuring advanced integrated control and drive technology that combines mechanical, electrical, pneumatic, and instrumentation systems, it is ideally suited for manufacturing inductors, magnetic cores, powder metallurgy components, and structural mechanical parts. The servo press incorporates independent servo and electrical systems and employs floating‑pressing technology, allowing effective control over the density of the formed product. Two demolding options are available: protective demolding and standard demolding. Electrical control is implemented via a PLC programmable controller with centralized button operation, complemented by mechanical limit switches to ensure product consistency. This equipment is characterized by stability and high precision.

　　Advantages of the servo‑driven powder compaction machine: 1. A servo motor drives a lead screw to apply downward pressure; the drive unit itself generates pulse signals to convert position, display data, and stop operation, with the equipment governed by multi‑level control. 2. Two sets of servo motors, coupled via shafts to lead screws, precisely regulate the die cavity height. 3. At the rear of the die is a servo‑driven mechanism that reciprocates the powder‑feeding device, controlling both the feeding position and the amount of powder dispensed, resulting in a high first‑pass yield. 4. Each process step is automatically controlled by the system, enabling fully automated powder charging, powder delivery, and compaction. 5. The machine employs a PLC‑based touch‑screen control system, a floating die‑pressing mechanism, and a constant ejection‑position principle; regardless of part height, ejection always occurs at the same location. 6. A mold‑control system ensures precise positioning during molding, while a robust stop‑design for flat dies guarantees dimensional accuracy, yielding uniform density and reliable, durable products. 7. The up-and-down motion of the upper and lower slides, driven by a servo‑controlled screw system, gives the press superior powder‑compaction performance. 8. A specialized mold‑change and die‑holder installation system makes mold replacement significantly more convenient. 9. The press features a simple, straightforward structure, ensuring reliable operation and reducing mechanical failures when processing complex parts. 10. The equipment operates via human–machine interaction, with a simple design that is easy to use and maintain. 11. Multi‑layer digital management of pressing parameters—pressure and position—enables the formulation of optimal compaction recipes, supporting a wide range of pressed products with forming yields and first‑pass pass rates exceeding 95%.

　　Servo powder‑forming machines are suitable for industries that require powder compaction, such as inductor magnetic cores, powder metallurgy, ceramics, cemented carbides, and magnetic materials. They are particularly well‑suited for the compression molding of complex‑shaped, multi‑stage components. Applications include magnetic materials, integrated inductor manufacturing, ceramics, 5G filters, cemented carbides, powder metallurgy, fasteners, stamping, new energy, lithium batteries, automotive parts, and the 3C sector.

Backed by Tongyou Group and leveraging its end-to-end synergy across the “materials–equipment–devices” value chain, Huacui Weiguan is set to exhibit at CITE 2026, the 14th China Electronic Information Expo.

Smaller size, stronger performance! Huacui empowers smart wearable devices with extreme lightness and thinness.

In the current trend toward product miniaturization, inductor sizes continue to shrink to meet the demands of consumer electronics, automotive applications, fast‑charging systems, and AI devices for slimmer form factors and higher integration. Meanwhile, advances in high‑permeability, low‑loss magnetic powders and high‑performance coil materials enable small‑size components to satisfy requirements for high current handling and low losses.

Carbon Footprint Verification Report

Life Cycle Assessment (LCA) is a standardized, systematic, and quantitative methodology for evaluating the resource and environmental efficiency of a product throughout its entire life cycle. By tracing the production and consumption stages upstream and downstream, LCA helps manufacturers identify the specific phases where environmental impacts arise and facilitates the mitigation of their transfer across different life-cycle stages and among various types of environmental effects. Many industries, both domestically and internationally, have undertaken product LCA assessments to support benchmarking and continuous improvement within firms, foster external communication, and provide evidence‑based input for policy formulation.
