The Bonnell assembler SX200 is a fully automated machine designed to assemble interconnected Bonnel springs into mattress cores at a rate of up to 1,000 springs per hour. It accepts pre-formed steel coils with diameters of 82 mm to 92 mm and heights of 12 cm to 16 cm, aligning them into a grid pattern with precise spacing. The machine does not manufacture springs but assembles them using a servo-driven feed system and pneumatic clamping to maintain alignment.
The system features adjustable guides for spring diameter and spacing, allowing operators to configure the machine for different mattress sizes and support densities. The control panel includes programmable memory for up to 10 different assembly patterns, enabling quick changeovers between product lines. The machine is built with industrial-grade steel frames and servo motors, designed for continuous operation in high-volume production environments, though no IP rating or dust protection level is specified.
This machine is targeted at mattress manufacturers in Southeast Asia, Eastern Europe, and Latin America seeking to reduce manual labor and improve consistency in core assembly. Buyers typically require delivery of the machine with basic tooling for common spring sizes. Installation requires a 3-phase 380V power supply and compressed air at 6 bar. Lead time and training are not specified in the listing and must be confirmed directly with the supplier.

Before ordering the SX200, confirm the exact spring dimensions and spacing requirements of your mattress design. Request a live demonstration or video of the machine assembling your specific spring type. Verify that the power supply at your facility matches the 3-phase 380V requirement and that compressed air is available at 6 bar with filtration. Do not rely on the supplier’s claims without independent verification of performance metrics.
Confirm the Incoterms offered, typically FOB Ningbo or Shanghai, and whether the supplier provides installation support or training. Lead time is not stated but typically ranges from 4 to 8 weeks after deposit. Payment terms are usually 50% advance and 50% before shipment. Request a packing list detailing machine components, tooling kits, and spare parts included, as these vary by order configuration.
Upon delivery, inspect the machine for shipping damage and verify all components against the packing list. Test the machine with your actual springs before full production, checking for alignment accuracy and cycle consistency. Retain the first 10 assembled cores for quality tracking. Request a calibration certificate and ensure all safety features are functional. Document the setup process for future maintenance and operator training.
