Saint Louis mixers are the only mixers able to blend the investment for fusion - eliminating any gas presence thanks to a procedure patented; in fact until very recently investment used to be added to water and blended under climatic atmospheric pressure which fused together the gas contained in the water with that found in the air, causing great difficulty in de-gassing the product, both before and after pouring it into the cylinder. The only obvious solution was to invent a machine capable of de-gassing the components before blending them and then working them under vacuum. The Saint Louis mixer solves these problems and furthermore it shortens working times and guarantees the operator maximum hygiene.


We can therefore declare that our mixer is the most technically advanced for the preparation of investment thus offering

complete de-gassing of the investment

various mixture speeds suitable for every type of investment

memorization of mixing time

the exact amount of water by means of it's graded tank

the possibility of vibrating the investment already present inside the cylinder, verifying vibration intensity

double plate (P1) which permits the shifting of the cylinders from the machine without lifting them during the very delicate hardening phase of the mixture


These characteristics allow the achievement of a perfectly compact mixture granting the best results in the baking phase of the mixture therefore guaranteeing strong resistance and a perfect smoothness to the substance being poured. The economic advantages are surely obvious when considering the amount of working time saved, also for the Saint Louis 92 mixer, by limiting the investment waste and always the same quality of product.
