Thermoset injection moulding

Thermoset package for precision equipment: highly wear-resistant cylinder modules, special plasticising screws, function-enhanced machine controller for venting and injection compression moulding.

Benefits at a glance


For high-quality thermoset moulded parts you need suitable temperatures, special plasticising screws and venting, plus real expertise. And we have just that.


Looking for materials for tough cases? With granulated thermosets and moist polyester (BMC), you can achieve a high degree of mechanical strength and rigidity.


Abrasion resistant, heat resistant, electrically insulating, resistant to chemicals? Then thermoset injection moulding is the answer. And ARBURG's expertise will be of interest to you.


Reliable hydraulic or vertical ALLROUNDERs and a practice-oriented thermoset package: with this system solution, you can immediately start high-quality series production.

Benefits of thermoset injection moulding

INJESTER für die Duroplastverarbeitung

Short sprues

Short sprues

With temperature-controlled cold runner extended nozzles with an immersion depth of up to 100 mm for material-efficient work.

Reliable venting

Reliable venting

Reliable machine controller, air and cross-linking gases escape easily, parts with no shrink holes – also for repeated venting during the holding pressure phase.

Special cylinder modules

Special cylinder modules

Highly wear-resistant in robust bimetal, adapted injection units for granulated thermosets and moist polyester (BMC) for high production quality.

Screw-type INJESTER

Screw-type INJESTER

With servo-electric conveyor screw, large refill container that can be filled during production, high degree of autonomy.


BMC cylinder

Need a reliable and automated solution for feeding materials with a high filler content? Our INJESTER tamping device can handle it! For optimum pre-compression to minimise trapped air and gas.

Sample components

Insulating rail

To produce heat-resistant thermoset insulating rails for irons, fibrous BMC is optimally pre-compacted with an INJESTER tamping device.

Car piston

A piston made of granulated thermoset, cost-effectively produced on a hydraulic ALLROUNDER injection moulding machine, can replace metal in car couplings.

Armature shaft

In armature shafts for electric motors, thermoset ensures a secure connection between the shaft and the stamping package.
