Machine Description
The Mechanical Bellow Forming Machine is
a high-precision, robust forming system
designed to produce metallic bellows
through mechanical punch-forming
technology. It is ideal for manufacturing
expansion bellows, automotive exhaust
bellows, and flexible connectors using
stainless steel and high-performance alloys.
This machine utilizes a segmented die
system operated via mechanical linkages or
cams, delivering consistent convolutions
with excellent repeatability, speed, and
strength. Suitable for medium- to high-
volume production, it offers low operating
costs and minimal maintenance.
Features
• Mechanical forming system using punch and segmented die design
• Suitable for SS304, SS316, SS321, Inconel, and other alloys
• High-speed forming with consistent convolution geometry
• Adjustable stroke and indexing for variable pitch and height
• Rigid frame for vibration-free and long-life operation
• Low operating cost compared to hydraulic systems
• Ideal for expansion joints, exhaust systems, and EGR bellows
• Minimal power consumption with continuous duty cycle
• Optional automatic loading/unloading system
