How to Prepare Thermoplastic Sheets Before Bending

Good bending starts before the machine is turned on. Confirm the polymer, thickness, bend direction, surface condition and protective-film requirements, then cut clean edges and mark accurate centerlines.

Why it matters

Dust, chips and scratches can be pressed into a hot surface. Wrong material labels can lead to unsafe or unusable settings. Preparation protects both quality and operator time.

Practical checklist

· Clean the sheet and work surface with a compatible method.

· Remove chips from cut edges and inspect for cracks.

· Keep material labels with the job until production is complete.

Which machine fits?

Both machines process several thermoplastics, so clear material control is essential when different sheets share one workshop.

Frequently asked question

Can a scratched sheet be bent successfully?

It may bend, but heating and forming can make surface defects more visible. Use acceptable material for the finished quality level.

Always test a small offcut and follow the machine manual, material safety information and local rules.
