Halffabrikaten
• Walsen
• Extruderen

Halffabrikaten zijn geen eindproducten -> ze moeten verder worden verwerkt
in constructies via verbindingstechnieken

De wanddikte bij plaatbewerking is overal gelijk, aangezien je vertrekt van 1
plaat.




Walsen
Walsen is een vormgevingstechniek waarbij een dikke plaat metaal door twee of meer walsrollen wordt
omgevormd tot vlakke platen, folies of profielen.

• Warmwalsen: materiaaleigenschappen veranderen niet
➔ Hiermee dieptrekken en lassen

• Koudwalsen: materiaaleigenschappen veranderen wel
➔ Heel sterk staal
➔ Als je een klein beetje moet vervormen
➔ Gebruikt in witgoedsector
