A corrugated plastic panel is produced by providing a plastic panel corrugation device whereby a plastic material is extruded, a cooled extrusion is formed by passing the extrusion through a cooling roller assembly, a corrugated extrusion is formed by passing the cooled extrusion through a forming roller assembly when the cooled extrusion has reached its impressionable temperature range, a corrugated extrusion is passed through a pulling roller assembly when the corrugated extrusion has reached its hardening temperature range, and a corrugated plastic panel is formed by passing the corrugated extrusion through an extrusion cutting assembly.
Fabrication d'un panneau de plastique ondulé au moyen d'un dispositif pour onduler le panneau de plastique, où un matériau plastique est extrudé, une extrusion refroidie est formée en passant l'extrusion à travers un rouleau refroidisseur, une extrusion ondulée est formée en passant l'extrusion refroidie à travers un rouleau de formage lorsque l'extrusion refroidie a atteint sa plage de température d'impression, une extrusion ondulée est passée à travers un rouleau de pression lorsque l'extrusion ondulée a atteint sa plage de température de durcissement, et un panneau de plastique ondulé est formé en passant l'extrusion ondulée à travers un dispositif de coupe d'extrusion.
