Silicone injection moulding

Liquid silicones, solid silicones? We have the perfect system solutions for you – because we have accompanied this technology for decades.

Benefits at a glance


From liquid or solid to highly elastic. With solutions from ARBURG, you can interlink liquid silicones (LSR) and solid silicones (HTV/HCR) at high temperatures and achieve perfect silicone properties.


Want to produce odourless and tasteless parts? Neatly finished and immaculate? Our ALLROUNDER injection moulding machines produce flawless silicone products.


Abrasion resistant, UV and ageing resistant, heat resistant, electrically insulating, resistant to chemicals, sterilisable. Silicone injection moulding is the answer.


Working with moulds hotter than 200 C and vulcanising LSR and HTV/HCR? If you mix liquid components homogeneously, tamp solid compounds correctly, work professionally: ARBURG.

Sample components

2C push button

Twice as soft: the 2-component push-button combines the different properties of two silicones with different Shore hardnesses.

Flow straightener

A flow straightener made of PBT and LSR is produced for a shower valve with a 2+2-cavity mould. With hot runner technology for thermoplastic and cold runner technology for LSR.


High quality face mask made of soft LSR and a solid PP shield. Four LSR masks are produced per cycle and removed by a six-axis robot.
