SX-820i AUTOMATIC BONELL TRANSFER MACHINE
This is latest model for producing “Bonell” type innerspring units. It can produce innerspring units directly from wire.
- Firstly the steel wire is coiled to a spring;
- Then transferred and inserted to the assembler by the automatic feeding system.
- After this, the upper and lower springs are coiled together at the same time and helical wire is coiled, cut and clamped at both ends automatically.
- When a unit is finished, it could be ejected automatically.

SX-80is DIGITAL SPRING COILING MACHINE
This model produces Bonell springs for mattress at speeds of 80 pcs/min.
In a single cycle, the wire is coiled to a spring, knotted at both ends, heat treated and to be collected to an outlet channel. The coiler utilizes a fully integrated computerized Programmable Logic Controller (PLC) and Servo control system, also with two CPU and high sensitive touch screen to reach remote-control support. All machine functions including wire feeding length, heat treatment, lubrication and self-protecting are automatically controlled.

Technical data
SX-200s AUTOMATIC SPRING ASSEMBLING MACHINE
This machinery is for assembling Bonell springs.
The features include:
- Can be operated by one person efficiently.
- Accepts variation of steel wire gauge, spring end ring, spring height and produces spring units within a certain limitation.
- Coils upper and lower springs together at same time automatically.
- Helical wire is coiled, cut, and clamped at both ends automatically.
- Spring rows can be set on the computer, and the spring units can be ejected automatically when the number of set rows is achieved.

Technical Data
SX-100T/100T2 AUTOMATIC BONNEL TRANSFER MACHINE
It can produce innerspring units directly from wire.
In a single cycle, the wire is coiled, shaped/knotted, heat-treated, face to face transferring and assembled into an units. The model has a digital servo control system.
Advantages:
- Special face to face t assembly can solve all issues of incline happened when you press all the units in bonell/offset/LFK etc.
- Good for roll packing.
