The fuselage adopts six-column, eight-column, and frame structures, which have good guidance performance and accuracy guarantee characteristics.

The main oil cylinder adopts a double-cylinder, three-cylinder, or six-cylinder arrangement. Components such as ejection cylinders and hydraulic pads can be configured according to user needs.

The upper oil cylinder generates the edge pressing force. The ejection force generated by the lower cylinder can emboss deep patterns and reduce wrinkles. The effect is particularly obvious.
