2022-08-06 16:18

The Tongyou Intelligent Inductor Automatic Winding Machine is an automated solution specifically designed to address coil-winding processes in the semiconductor industry.

Tongyou Intelligent presents a series of insights on the manufacturing of T-Core and PIM integrated molded inductors.

Including the materials and equipment for inductors, as well as the manufacturing process for monolithic microinductors.

Today, we introduce the second piece of equipment in the process flow— Automatic winding machine

Automatic winding machine What is it?

The inductor automatic winding machine is an automated device specifically designed to streamline the coil-winding process in the semiconductor industry.

The purpose of the automatic winding machine is:

The automatic winding machine neatly arranges the specified copper wire on the cold‑pressed core’s central post according to the prescribed number of turns and pitch, and secures both ends of the wire to the protruding tabs of the cold‑pressed core.

Features of the automatic inductor winding machine:

Production yield: 98% or higher;

CT equipment: 0.2–0.5 seconds per unit;

Winding method: dual-axis simultaneous operation, with multiple layers of windings wound concurrently;

Winding coil count setting: Enter the number of turns, and the equipment will automatically calculate and produce accordingly.

Copper wire tension control: A multifunctional digital tension meter is used to monitor copper wire tension in real time.

Inductance Automatic winding machine Process flow:

Material feeding: Automatic feeding is achieved using a vibratory bowl feeder, with the bowl equipped with built-in functions for automatic material screening and removal of broken pieces.

Wire feeding: Equipped with a digital, adjustable automatic wire‑tensioning device that continuously monitors wire tension and maintains the tension within a set range, ensuring reliable winding performance.

Wire winding and forming: We have independently developed an integrated module for material handling, wire clamping, and winding, enabling simultaneous dual-axis winding. Additionally, the number of windings can be adjusted according to product requirements or the type of copper wire used.

Cutting and Spot Welding: An in-house developed integrated module for edge folding, cutting, and spot welding, featuring convenient adjustment to accommodate varying product specifications and parameters.

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.
