CTM Mixers for Compounding
The CTM Conical Twin Mixer is a patented mixer consisting of a conical mixing chamber with two conical screws and two heads: one head is completely closed and is used during the mixing process and the other head containing a die is used during the extrusion process. CTM is able to mix a silicone compound consisting of silicone base, liquid or powder fillers, peroxide or platinum catalysts and color pigments. The entire mixing process can be completed in a single step, automatically keeping the batch temperature below the maximum allowed temperature of the recipe, without the operator’s intervention. All surfaces in contact with the silicone compound are cooled to avoid any increase in temperature in the batch during the mixing process.
The CTM is self-cleaning. The conical shape of the screws, combined with the shape of the inner surface of the mixing body, allows the batch to be completely unloaded. The conical body can be automatically separated from the screws by hydraulic opening.

CTM Mixers for the Medical Sector
Colmec designs and develops mixing systems for installation in clean rooms that are able to meet medical industry requirements in accordance with cGMP/FDA and OMS standards, 21CFR11 software part 11 FDA. All mixer components in contact with the material are made according to FDA requirements and depending on the different specifications are supplied with surfaces with special coatings, stainless steel or nickel-plated. Each processing phase is controlled by means of the Colmec supervision system that integrates all the components and allows centralized data management.
