2K Co-Injection Moulding
Machine
This machine from the prestigious Austrian
manufacturer Battenfeld is a 2007 horizontal injection moulding
machine with 100 tonnes clamping force and a special Co-Injection
(Sandwich Injection) configuration.
How Does Co-Injection
Work?
The two injection units do not operate independently
— they meet inside a combined nozzle. First, Unit A injects: the
first material adheres to the mould wall and forms the outer skin.
Then Unit B follows: the second material flows into the core of the
first, pushing it forward. The result is a part with an outer skin of
Material 1 and a core of Material 2. If both materials are injected
simultaneously or overlapping, a decorative marble or blended colour
effect is achieved. The entire process takes place in a single cycle
with a standard mould — no expensive rotary platen tooling is
required.
In the current production of this machine, Unit A
feeds green and Unit B feeds yellow material of the same plastic type,
both injected simultaneously through a single combined nozzle into the
mould. As the green and yellow materials flow side by side and into
each other, a natural marbled colour effect is created on the part
surface. Permanent and visually appealing coloured surfaces are
produced in a single cycle — no labels or post-painting required.
