without accessories.
Marbling
During marbling, coloured surface effects
are achieved by inhomogeneous mixing of
several plastics in one injection unit. Consequently, there is no clear colour separation
and the colour effects are not reproducible.
Core-back process
During the core-back process, the cavity is
extended by pulling a slide and a second
component injected. The sequential cycle is
especially suitable for moulded parts with
simple geometries.

Advantages
Simple, cost-effective mould technology
no transport of pre-moulded parts, movements integrated in mould
High number of cavities per mould
surface area
Flexible operation: transfer both within the mould and between two injection moulding
machines possible.
Advantages
High number of cavities with small mould
surface area
Comparatively low locking force required
Loading of inserts during injection moulding process and integration of operations
to pre-moulded parts possible
Rotation technology
Here, the pre-moulded parts are transferred
to the second station via a horizontal rotary
movement. They are not fully demoulded,
but remain in the part of the mould that is
rotated. Internal or external mould rotary
devices are required for this purpose.
A distinction is made between rotation
of a mould half, a platen or an insert.
The last two procedures are also referred
to as index rotation.
www.arburg.com 01/2016
Transfer technology
With this process, the transfer of premoulded parts to the second station via a
robotic system takes place directly in the
mould, or in a second machine.
Important: integrated robotic systems
If, as with ARBURG, the robotic systems are
fully integrated in the SELOGICA machine
control system, the robotic and mould
movements can also be fully synchronised.
This results in a high degree of process reliability, flexibility, shorter cycles and therefore enhanced cost-effectiveness.

Advantages
Simple, cost-effective mould technology
Robotic system can be used for further upstream and downstream production steps
Thermally separated mould areas can be
implemented
Production steps to the pre-moulded part
can be integrated
Also ideal for bulky inserts
injection moulding process. During procedures of this kind, transfer processes (transfer technology, rotation technology, turning
stack mould technology) are generally used.
Important: Optimum material
combinations
The requirements relating to the moulded
part are crucial during material selection.
This should therefore always be performed
in collaboration with the material producer.
ARBURG can provide assistance with its
well-founded expertise and its contacts.
Advantages
Joining techniques or downstream assembly steps can be dispensed with

On the clamping side, electric ejectors and
core pulls are available as well as
hydraulic ones.
Flexible configuration
Several different positions of the injection
units with respect to one another are possible. These are freely combinable, as the
mould and process technology requires.
Solutions with up to six components have
already been realised. This means that individual, customised machine technology is
available to suit every application.

it is important that the parts status is communicated from station to station. This allows reject parts to be reliably detected. An
additional benefit is that here is only one
data record for the complete production
unit, including accessories such as rotary
units or robotic systems. Altogether, this
ensures a high level of user convenience.

Efficient mould concept: the injection moulding process and parts handling run simultaneously.
Soft-touch keypad
On a customised system for production of a
washing machine keypad, thermoplastic
and silicone are processed to form a hardsoft combination. Here, various material
properties can be brought together in a single production step. A particular challenge
is the joint processing of hot and cold
materials in one cycle and one mould: LSR
crosslinks at high temperatures, whereas PA
requires cooling. The relevant sections in
the mould must consequently be separated
from one another by means of thermal insulation. This is why transfer technology is
particularly suitable here. The moulded
parts are transferred in the mould via a
MULTILIFT robotic system.
