Frequently Asked Questions
The SX-90 is a fully automated production device specifically designed for manufacturing Bonnell spring cores, catering to the needs of small and medium-sized enterprises (SMEs).
The machine operates at a high-speed production capacity, coiling and assembling around 85 to 90 Bonnell springs per minute.
In a single cycle, the wire goes through a sequential operation of coiling, shaping, heat-treatment, face-to-face transfer, and final assembly into a finished unit.
The exclusive face-to-face assembly approach solves potential inclination issues that can happen when compressing units in a Bonnell spring structure.
It supports multiple configurations including: standard setup, face-to-face assembly, alternating rows (knots facing left/right to keep diagonal deviation under 1cm), and a customizable DIY option (5 knots left, 5 knots right).
Yes, customized spring shapes can be manufactured and provided based on specific customer requests.
