Krauss-Maffei GmbH of Munich Germany has recently installed the 100th CX
Duroset injection moulding machine at Austrian plastics processor MKW,
where it will to be used to produce thermoset plastic components.
The 100th Duroset machine installed was the CX 80-750 DUR, which is
equipped with the DuroSet process, working with free-flowing granulates.
It’s versatility means that it is also capable of handling polyester
moulding compounds. MKW will use the machine to produce components of
office furniture that would typically have been made of die-cast metal.
The manufacturing cell includes a LRX 50 linear robot for transverse
parts removal.
Thermoset parts are used in a wide range of demanding applications such
as lighting and electrical components, under hood automotive, headlight
components, water pump components, brake pistons gears, pulleys etc.
Important characteristics of thermoset materials are high strength,
stiffness and hardness as well as outstanding resistance to temperature
extremes.
Krauss Maffei thermoset machines feature highly wear-resistant screws
without a non-return valve. The plasticized material is injected into a
heated mould, under pressure and heat, the material cures by way of
chemical crosslinking (polymerization). The plasticizing process is
tailored exactly to the specific thermoset compound. The screws are
characterized by high drive moments, high injection pressures and low
screw speeds. A liquid-based temperature-control system for the barrel
keeps the compound at precisely the right temperature. Included in the
comprehensive standard program are functions such as mould-breathing and
compression control, automatic purging and finely adjustable back
pressure.
The Duroset series is part of the popular CX injection moulding machine
series which covers the small to medium clamp force range (35 to 650t)
and is popular for its high flexibility, cost effectiveness and high part
quality.
Krauss Maffei manufactures state-of-the art Injection Moulding machines,
Extruders and ancillary equipment and is represented in Oceania by HBM
Plastics Technologies.
