END-O-MAT0 pages

The END-O-MAT system is a combined machine system for medium and high
speed end production.

Processes, can/end requirements and machine requirements for thin and low cost cans
and ends with high strength:
Process
Die-necking

Can / End requirement
high axial resistance:
axial resistance is mainly
determined by the necking
angle

Machine requirement
steep neck angle smaller than 30
degrees
neck re-forming by second necking
operation

Beading

interdependence of axial
and paneling resistance

Seaming of
DR ends

adapted seam dimensions
(SEFEL)
m
mini-flange
mini-curl on the end

Production
of DR ends

sufficient resistance
thanks to optimized
geometry and
sufficient countersink
depth
precise curling
(mini-curl)

beading method
number of rotations and advanced bead
depth forming
bead geometries optimized by FEA
calculation

seaming method:
number of rotations and advance seam
forming
only minor fluctuation of flange
dimensions
swing-flanging

multi-die stamping press:
rigid machine design
multi-stage or thermo compensating
tooling
FEA optimized panel design disc
curler: number of rotations
