China SX-90 Automatic Bonell Spring Transfer Machine - Leading Suppliers & Factory for High-Speed Production

Product Information
In a single production cycle, the wire undergoes a sequence of operations: coiling, shaping, heat - treatment, face to face transfer, and is ultimately assembled into a unit. The machine is equipped with a digital servo control system.
Key Advantages
- Speed: 90 springs/min
- Good for roll packing
- Helical wire can be clamped (option)
Spring Direction Control Options
- Control the direction of each spring:
- Standard one
- Face to face assembly
- One row knots face left, one row knots face right (makes the deviation of diagonal line less than 1cm)
- 5 spring knots face left, 5 spring knots face right (DIY)
Frequently Asked Questions
Q What is the production speed of the SX - 90?
The SX - 90 operates at a high-speed rate, capable of coiling and assembling approximately 85 to 90 Bonnier springs per minute.
Q How does the SX - 90 solve spring inclination issues?
It utilizes an exclusive face to face assembly approach that efficiently resolves potential inclination issues when compressing units in a Bonnell spring structure.
Q What steps are included in a single production cycle?
During a single cycle, the wire goes through a complete sequence of operations: coiling, shaping, heat-treatment, face to face transfer, and final assembly into a unit.
Q What options are available for controlling spring direction?
The machine supports four configurations: standard assembly, face to face assembly, alternating rows (one row knots face left/one row face right for diagonal deviation under 1cm), and a custom DIY setup (5 knots face left/5 knots face right).
Q Is the SX - 90 suitable for small and medium-sized enterprises?
Yes, the SX - 90 is specifically crafted to meet the production requirements of terminal small and medium-sized enterprises (SMEs) within market niches, bridging the gap between high efficiency and accessibility.
Q Can customized spring shapes be manufactured?
