ENGEL combimelt based on an ENGEL victory makes visions reality
Product ideas are formulated visions. They
can be realized only with the aid of a broadly

combimelt stands for applicational concepts
and their realization with proven machine tech-

provide the basis and scope for turning visions

Injection units in “L” arrangement
Injection unit combinations in “L” arrangement afford free ac-
cess to the plasticizing unit. The nozzles can be centred by
means of a crank mechanism for coupling to the stationary
and moving platens. “L” combinations can be used in a wide
range of sizes on all basic machine models.

The machine equipment packages for the combimelt multi-
component injection moulding process are generally of
modular construction and comprise:
The smooth construction of the tiebarless clamp is ideal for
- injection units from Engel’s entire range of models combining additional injection modules
(including ENGEL elast units)
- drive modules – hydraulic
- ENGEL CC 200 control system: the integrated
Multimaster system permits the control of time-
critical parallel processes with just one control
system. Using the standard ENGEL MICROGRAPH
PLUS software, the control system displays the
process curves of all injection units simultaneously
and in real time on a high-resolution VDU
- rotary-table units, available in diameters
of up to 2 metres
On a linear bearing attached to the baseframe of the machine
the second injection unit can be easily adjusted on the
required position

Injection unit in “V” arrangement.
Vertical injection units (“V” arrangement) are mounted above
the stationary platen on a moving carriage. When the mould
has to be changed, the vertical injection unit can be pushed
back in the direction of the horizontal injection unit. This de-
sign feature also permits easy and exact centring of the injec-
tion nozzle in relation to the gate.

Machines featuring combined horizontal and vertical injec-
tion units can be readily converted for co-injection. To this
end, the rails for the moving carriage are extended towards Adjustable carriage for positioning of vertical injection unit above
the horizontal unit, permitting connection of the two units by the injection mould
means of the special co-injection nozzle. This co-injection
facility has proved particularly ideal for use with small and
medium-sized machines.

Rotary tables: Special solutions
universal, service-proved, efficient for special projects

Engel rotary tables
- Engel rotary tables are available in a range of - All rotary tables have provision for the fitting of lead-
diameters from 600 mm to 2000 mm. Other through couplings for the media (including multi-circuit
(special) sizes are also available – please enquire heating-cooling water or oil)
- Rotary table drives are generally hydraulic - All rotary tables are available for two-, three- or
