Recently, the SIPU team visited the 29th CAPAFAIR (Ningbo International Auto‑parts & After‑market Exhibition). We had in‑depth communications with many auto‑parts manufacturers about production pain‑points and automation upgrading solutions for ignition coils, horn coils and relays. With our Ningbo service site, we can quickly support customers in Jiangsu‑Zhejiang‑Shanghai area. Insights from this exhibition will be applied to optimize our coil‑automation equipment to help manufacturers boost production capacity and expand overseas markets.

Two sets of SIPU multi-spindle automatic winding machines have passed final factory inspection and are ready for delivery to Pakistan. These dedicated machines are independently optimized for primary ignition coil and secondary ignition coil mass manufacturing. Targeting fast-growing demand within Pakistan’s automotive industry, SIPU upgrades equipment to adapt to local workshop conditions and provides stable automation solutions for local auto component producers.

SIPU’s full-series coil automation machines (6–32 spindle winders, soldering & insertion machines) feature standardized refined details. Equipped with servo tension control, pigtail wire guides, infrared bobbin detection, wool felt protection, and constant-temperature solder pots, all equipment maintains unified precision for standalone or tandem production. These reliable designs reduce coil defects and ensure stable mass production of automotive, relay, and valve coils.

SIPU supplies full RoHS & REACH compliant eco coil production materials: halogen-free enameled wire, lead-free solder and flame-retardant wrapping tape. Matched with our low-energy winding, taping and soldering machines, the one-stop green solution helps electronics factories pass export audits, cut material waste and realize low-emission, cost-effective coil manufacturing for automotive and new energy industries.

Many coil manufacturers face high tin slag loss and unstable soldering quality when using traditional solder bath for coil pin processing. This article compares soldering iron, rectangular solder bath and deep cavity solder pot three mainstream coil soldering processes, analyzes their differences in structure, temperature control and maintenance cost. Xiamen Sipu Mechanical provides customized automatic coil soldering equipment with solder pot or solder bath structure, helping electronic factories reduce tin consumption and improve coil welding yield for relay, transformer and automotive electromagnetic components.

SIPU's self-developed full-auto 13F relay coil production line is delivered to an auto electronics factory. This 7-in-1 integrated 32-spindle line reaches 500–600 pieces per hour with over 99.5% yield. The open-frame design simplifies maintenance and supports MES data connection. This flexible equipment can also be customized to produce solenoid valve, motor stator and VCM coils for global manufacturers.

Rising copper, steel, and rare earth magnet prices are pressuring coil winding equipment manufacturers globally. This article analyzes current material cost trends and how SIPU Mechanical maintains competitive pricing through supply chain management and scale manufacturing—without cutting equipment quality.

Xiamen SIPU returns from CWIEME Berlin 2026 with key insights into European coil buyer demands — precision relay coils, ignition coils, and custom coil solutions for new-energy and automotive applications.

New energy high-voltage coils demand high precision winding and tension control. This article covers these challenges and shows how Sipu's servo-controlled winding machines and full-automatic lines help coil factories achieve consistent quality for photovoltaic, energy storage and new energy vehicle projects.

You use coil winding technology every day. It is in your phone and electric cars. Coil Winding Techniques help wires become strong parts for electronics and energy systems. In the past ten years, coil winding machines have become more popular. This is because new tools are available and more people want them.
