🌍 SIPU Advances Coil Automation in 2025

Over the first ten months of 2025, automation in coil manufacturing has entered a new era. Driven by global electrification, the rise of electric vehicles, and growing demand for efficient HVAC systems, coil production has become one of the fastest-evolving fields in modern manufacturing.

Processes that once relied heavily on manual labor — from winding to final assembly — are rapidly shifting to precision automation, data monitoring, and intelligent control. Around the world, and particularly in China, more manufacturers are upgrading coil production to achieve greater efficiency, stability and flexibility.

Market drivers and background

Demand for coils is surging across multiple sectors:

• Automotive: EV motors and solenoid valves need coils with high precision and reliability.

• HVAC & refrigeration: expansion valve coils are critical to maintaining efficient system control.

• Industrial control & renewable energy: relay and transformer coils support smarter, greener power systems.

Recent market reports show steady growth in coil-related markets. For example, estimates for the expansion-valve segment vary by source, but several market studies place the air-conditioning expansion valve market in the multi-billion-dollar range (many reports cite figures around USD 4 billion and up, depending on scope and definition). 

China's strong supplier ecosystem and integrated equipment design capability are accelerating automation upgrades, helping local suppliers respond quickly to both domestic and overseas demand. 

SIPU's progress: from winding to full assembly

In recent years, Xiamen SIPU Mechanical Co., Ltd. (SIPU) has become a leading Chinese provider of coil automation solutions, with products that include precision winding machines, soldering and terminal insertion equipment, coil inspection systems, and complete assembly lines. SIPU's ability to provide end-to-end equipment—from coil winding through to automatic assembly—is a competitive advantage for customers who want a single-source solution. 

A highlight of 2025 is SIPU's new expansion valve coil assembly line. Unlike traditional lines that depend on manual insertion and hand crimping, SIPU's system automates part feeding, pin insertion, crimping, assembly and inline inspection. The result is a smooth, precise and traceable process: every unit is assembled with consistent force and alignment, and production data is recorded for quality control. 

Thanks to this solution, several customers have successfully shifted from manual assembly to automated, high-speed, data-driven manufacturing — an essential step toward Industry 4.0.

What 2025 is showing the industry

Across the globe we see several clear trends:

• Automation expands beyond winding. Assembly tasks — pin insertion, crimping, pressing and electrical testing — are now prime candidates for automation.

• Modular, flexible lines are preferred. With  Stock Keeping Unit （SKU） proliferation, manufacturers need quick changeovers without long downtime.

• Smart Quality Assurance （QA） becomes standard. Vision inspection, AI-assisted quality checks and per-unit traceability are moving from "nice to have" to "must have."

• Asia leads adoption speed. Data show Asia (led by China) accounts for the majority of new industrial robot deployments, making rapid automation rollouts possible. 

• Energy efficiency and sustainability matter more. Precise, repeatable coil production helps OEMs meet increasingly strict efficiency and emissions targets. 

Global vendors and the competitive landscape

The market includes a mix of established international and regional suppliers. Examples include winding and automation specialists such as Marsilli (Italy) — known for motor and coil winding systems — and a range of robotics and automation leaders such as Fanuc and Yaskawa (Japan), and industrial automation groups like Siemens and Bosch Rexroth (Germany). In Taiwan, companies such as   Teeming  Machinery  supply precision insertion, winding and soldering equipment for coil manufacturers. These firms, together with local Chinese integrators, form the ecosystem that accelerates line-level automation globally. 

SIPU (Xiamen SIPU Mechanical & Electrical Co., Ltd.) has also become a strong force in this evolving landscape. As a Chinese automation equipment manufacturer, SIPU delivers full coil production solutions — from winding to soldering and assembly — helping customers transition from manual to intelligent, high-speed production. Its continued innovation and flexible integration capabilities have allowed SIPU to stand alongside leading global brands in the ongoing automation upgrade wave.

Large OEMs and system buyers — for example, battery and EV leaders such as CATL (Contemporary Amperex Technology Co., Limited) — further drive demand for scalable, automated coil production through their sourcing and quality requirements. 

SIPU's vision: precision to intelligence

For SIPU, automation is not only about replacing manual work. It is about building smarter, cleaner and more efficient factories. By integrating motion control, servo systems and intelligent sensors, SIPU's equipment controls critical parameters such as wire tension, crimp force and component placement with high accuracy. Each line records production data in real time, enabling customers to monitor quality, schedule predictive maintenance, and continuously improve processes.

This data-driven model reduces human error, raises throughput, shortens lead times and lowers unit cost — helping manufacturers produce more and better with fewer resources.

Collaboration, training and market outlook

Throughout 2025 SIPU has strengthened partnerships across India, Southeast Asia, Europe and the Middle East, delivering tailored coil production solutions and accompanying on-site training, commissioning and technical support. Recent customer trainings and factory visits underline SIPU's commitment to long-term service: customers gain not just equipment, but operational know-how to transform their factories.

Looking ahead, coil manufacturing will continue moving towards full automation — from winding and soldering to assembly, inline testing and packaging. Suppliers that offer integrated, traceable and service-backed solutions will be best positioned to win large OEM contracts.

Conclusion

2025 is a pivotal year for coil production automation. Whether for expansion-valve coils, relay coils or motor windings, manufacturers that combine precision winding, automatic assembly, smart inspection and data traceability will secure competitive advantage.

SIPU, with its complete lineup of coil automation equipment and end-to-end system capability, is ready to help customers make this transition — from manual manufacturing to intelligent, high-efficiency production.
