Import Automatically Spring Coiling Machine — Buy in Bulk from Supplier in China

The Sunshine International Automatically Spring Coiling Machine is a fully mechanical system engineered for the production of bonnell type springs. It operates at high efficiency, simultaneously forming multiple springs to boost output while maintaining consistent precision. The machine’s industrial-grade construction ensures durability in continuous manufacturing environments, with adjustable settings to customise spring dimensions for varied production needs.

Bonnell springs produced by this machine typically use high-carbon steel wire, with standard wire diameters ranging from 2.0 mm to 5.0 mm depending on application. The coiling process achieves standard tolerances of ±0.5 mm on free height and ±0.3 mm on coil diameter, with typical spring indices between 4 and 8. Surface treatments such as zinc plating or powder coating are standard for corrosion resistance in automotive and furniture applications.

This equipment serves manufacturers in the automotive, furniture, and bedding industries where bonnell springs are a core component. Buyers source it for its ability to scale production while maintaining repeatability. Trade terms to confirm include MOQ, FOB or CIF delivery from Ningbo port, and ISO compliance documentation. The machine’s mechanical design reduces reliance on electronics, lowering maintenance demands in high-volume settings.

Sunshine International is based in Ningbo, Zhejiang Province, China, and operates as an imported-tier supplier with a harbor trust classification. The company’s listed address places it in a key manufacturing hub, and its profile indicates a focus on spring production equipment. No response rate or average response time is recorded, suggesting buyers should plan for direct outreach via listed contact details.

The supplier’s description highlights its specialization in spring manufacturing tools, with no additional claims about certifications, client base, or production capacity beyond the provided product details. Buyers should verify ISO compliance and factory audit status independently, as these are not explicitly confirmed in the available profile. The lack of response metrics underscores the need for proactive communication to assess service levels.
