ATTP designs and manufactures numerous machines for this sector of industry based mainly on 3 key processes :
- Tube punching without deformation : ATTP offers manual or numerically controlled variable-angle tube punching machines with Bigorne Expansive for punching tubes without deformation while accepting thickness tolerances. This type of application is used in particular to punch manifolds https://attp-constructeur.com/gamme-machines/poinconnage-avec-et-sans-deformation/
- Collar forming : This process is generally preferred for forming collars on ferrules. This extrusion process deforms a sheet or tube to form a shape by pressing a punch into a die. The result is a connecting flange that simplifies or eliminates the need to weld 2 parts together. https://attp-constructeur.com/gamme-machines/expansion/
- Tube expansion : ATTP offers manual stations as well as the integration of tube expansion units on manual or automatic feed machines. This operation also simplifies the welding process. https://attp-constructeur.com/gamme-machines/expansion/
