Sipu Mechanical custom automatic coil line for capacitor-integrated coils. It covers precision winding, terminal soldering, capacitor mounting, electrical testing, sorting and unloading. Modular flexible design supports quick changeover for various bobbins and capacitors, ideal for relay & solenoid coil mass production.
In October, SIPU ushers in a peak delivery season. After the National Day holiday, our workshop speeds up order production. Multiple automated coil production lines are under assembly and commissioning, and 2-3 complete production lines have passed quality inspection and ready for shipment. SIPU specializes in coil automation equipment with stable machines and many repeat customers. Our flagship project is the custom automatic relay coil production line. We also provide production lines for synchronous motor coils, horn coils and valve coils, supporting customized equipment appearance and process solutions.
Xiamen Sipu Mechanical delivers a custom automatic relay coil soldering machine: in-line layout, 800 pcs/h, one operator, CCD solder inspection, resistance and surge test, single or inline.
SIPU team visited VIIF Industrial Fair in Hanoi, Vietnam, to research local market demands for relay coil & precision winding automation. We held business talks with Korean and Vietnamese manufacturers, gaining first‑hand insights for Southeast‑Asian localized production‑line solutions.
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.
