This machine performs secondary die pressing, sealing and curling forming for battery and supercapacitor shells. It adopts positioning clamping sleeves; the upper booster cylinder drives the top sealing die to descend. During descent, the taper sleeve contracts the annular die fixture to fully clamp the workpiece, then continues pressing to complete tight sealing.

Key Features

Annular die clamping structure fully wraps the O-ring area of shell sidewall, minimizing dimensional variation after sealing, delivering uniform sealing and reliable air tightness
Precision guide posts & guide bushes ensure ultra-high guiding accuracy and parallelism of upper/lower dies
Booster cylinder provides stable strong pressing force; no messy hydraulic oil refilling & contamination, easy to integrate into automatic lines
Adjustable sealing height for various product specifications; sealing pressure and holding time are configurable
PLC control system ensures stable and reliable operation with simple operation
Color LCD touch HMI for intuitive parameter setting and viewing
Heavy-duty welded steel frame with smooth polishing and baking finish for neat appearance
Equipped with safety light curtain and protective door for safe operation
