Pre-mixing
The two pre-mixing functions take care of both materials (plaster and investment material) individually, and prevent the powder from being forced out of the mixing area from the start. At the same time the mixing paddles "pick up" the powder from the upper edges through well directed movements of the now free flowing material. The mixing ratio, which is particularly important for the expansion behaviour, is therefore consistently maintained.
Pre-vacuum
The chemical reaction of the investment constituents causes gas to build-up in the material during pre-mixing. This unwanted gas is extracted by the pre-vacuum function before the main mixing stage.
Adjustable vacuum level
The adjustable vacuum from 70 to 100% prevents bubbles from forming on certain plasters and duplicating silicones.
The main mixing sequence
The new high performance Twister motors effortlessly maintains the programmed mixing speed for every material, every quantity and every beaker size.
Change of mixing direction
A change in mixing direction allows the powder to absorb the liquid more thoroughly and possible dry agglomerates (lumps of powder) are broken up.
Post-vacuum
Some investment materials and model materials are prone to producing gases at a later stage, even after the main mixing sequence. The Twister's post-vacuum helps to reduce these bubbles, which accumulate afterwards on the surface of the mixed material.
