Brother Union Machinery has designed and manufactured roll forming machines for Customers with high quality requirements, especially automotive industry. In the automotive industry. Cars' roll-formed parts use a variety of specifications, and most of the sections are more complex, and the dimensional accuracy is strict. And with the development of automotive lightweighting, car manufacturers reduce the wall thickness and to increase the strength of the materials.We are proud that we have participated in the high-yield strength car bumper production line manufacturing and supplied our roll forming equipment for world-renowned automobile parts enterprises.
Brother Union Machinery always focuses on boosting productivity of roll forming equipment to proper level,to balance the equipment purchase cost and production efficiency.
The modulus of elasticity of steel profiles is 3 times that of aluminum alloys, and the strength of steel buildings far exceeds that of aluminum alloy profiles.
Steel profile has more span than aluminum alloy
Steel, glass, and concrete have almost the same thermal expansion coefficient, so there is no need to leave expansion joints when installing steel frame doors and windows
Steel frame door much better at fireproof, anti-theft, explosion-proof, and bulletproof.
The fireproof performance of steel frame doors and windows is far better than aluminum alloy. The melting point of steel is 1500°, and the melting point of aluminum alloy is 600°.
Steel will not melt when exposed to fire, will not release corrosive gases, and the frame will remain stable
Steel profile system can meet different fire protection requirements
The steel profile is strong and stable, high load, and durable, it is the ideal choice for security application.
Steel profiles are suitable for high-frequency operation, such as commercial fire-rated doors.
Firstly, Aligning and leveling the roll former, find out the exact forming center line. Align the uncoiler, leveling machine, punching machine, shearing device and others based on the roll forming center line.
If the center line and level is not exact, readjust them until the requirements are met.
Before start the machine, set the space between low roller and up roller. Normally the distance is equal to steel coil thickness, further micro-adjustment should be carried out in the trial production.
If the steel plate thickness changed, please reset the up roller to make sure the spaces are even.
Roll Forming VS Brake Forming
|Roll Forming||Conventional Sheet Metal Fabrication|
|Typically holds tighter tolerances||Typically holds looser tolerances|
|Inline punching,notching,etc - elimates secondary operation||Mutiple operation required - shearing, notching, perforating, etc.|
|Complex shapes||Simple shapes|
|Longer part lengths||Most brake parts have limited length|
|High-speed production||Slower production speed|
|Lower labor costs||Higher labor costs|
|Potentially higher tooling costs||Potentially lower tooling costs|
|Longer set-up time||Shorter set-up time|
|Potentially more scrap||Potentially less scrap|
