The ZFU1200 double-layer vacuum forming machine is engineered for heavy-gauge materials that demand high clamping force and deep draw capability.
Unlike thin-wall forming where speed and cycle time dominate, thick-sheet forming prioritizes uniform heating through the sheet thickness, stable sag control, and balanced positive-negative pressure application to avoid wall thinning or internal stress.
"Double-layer technology requires precise synchronization between the two sheet layers during heating and forming."
This ensures delamination-free bonding and consistent final-part geometry. Proper sheet extrusion upstream — with tight thickness tolerance and flatness — is a prerequisite for reliable ZFU1200 performance on heavy-gauge PET, PP, and PS sheets.
