| The range
of rotary injection machines called "Cross-Linking" offers
interesting and profitable possibilities to the technology of moulding
copolymers of Etylen-Vinyl-Acetate (granuled foam cross-linked EVA).
Good results are reported in typical applications i.e. pram-trolley
and bicycle wheels, energy absorbing bumpers, cross knee-guards,
paddings, water buoyants for fishing nets, skyboot internal paddings,
slippers, soles, etc.
Main characteristics are:
- Clamping unit run by piston or toggle, with force from 300 up
to 1200 KN.
- Electrical heating of thermal insulated moulds.
- Screw pistoning injection unit with 2 thermoregu-lated heating
zones, to maintain plasticizing process at temperatures lower
than those for cross-linking and foaming agent decomposition processes.
- Process control run by a video PC unit, for setting, saving
and visualizing all injection parameters: dosing, times, temperatures,
speeds, pressures, back-pressures, alarms.
- Possibility of visualizing input and output real status, for
a quick trouble diagnosis.
- Hydraulic plant controlled by proportional valves.
- Safeties as per international rules, and following those of
country of destination.
System flexibility is offered by the possibility of moulding thermoplastic
materials on same machine. |
