This type of tubes and profiles are highly demand in the sectors of construction, automotive, aerospace, appliances, food industry and chemical and petrochemical industry.
The first step in the process of forming tubes and profiles is extrusion. For this, it requires a design with a known extruder barrel and a screw. After direct extrusions, or aluminum, proceed with calibration and curved.
Calibration tubes and profiles aims to achieve a given pipe diameter and has a circular shape needed for accurate and final part. To perform the calibration, are two processes: calibration for smooth wall pipe calibration rough wall pipe.
Pipe bending takes place in certain situations. For example, in the construction sector, to prevent or avoid uneven column. Ultimately, pipe bending aims to adapt the tube to the needs of the site where it will go in place. For pipe bending machines are required bending. Each type of machine has its own characteristics, but generally are made of steel or welded steel plate. Also typically have a three drag rollers to achieve a smooth surface finish without damage.
The bending machines can also be manual. Have a light weight, easy to transport and curve materials like brass, copper or aluminum.
