Reason why a cycle can be completed in just 6 hours

The turbo-mixers are able to degas the resin in a very short time thanks to the particular technique adopted (see the drawing): an anchor-shaped mixer rotates in a circular motion, while a high-speed screw generates the upward movement of the resin.

• The particular chemical formulation of the resin
• The technique used in the oven/autoclave to accelerate the heating process
• The techniques used in the construction of the casting molds.

For superior quality

Autoclave-oven with an overpressure of 3 bar

• Preheating, vacuum casting, and polymerization processes performed in a single autoclave
• A 3 BAR overpressure is applied at the end of the casting process to facilitate the drastic reduction of even the smallest air bubbles trapped during the casting process. This further reduces the presence of partial discharges in the coils. The 3 BAR overpressure requires special autoclaves.

A perfect solution for new plants and for the renovation of existing ones

Operating principle

The MX-ST consists of a tube containing a series of spirals that mix the two components (hardener and resin), reversing their flow direction many times (see Photo 10). The mixing of the hardener and resin components results in a theoretical subdivision of the resin and hardener with a volume of 2.9 - 10^-8 mm³, a volume almost at the molecular level, making the final product identical to that obtained in 3-mixer systems. The static mixer developed by Silmek is easy to use, economical, and compact. Our static mixer is equipped with a recirculation circuit for the components, preventing sedimentation inside the tubes. During the casting phase, the pressure is constantly monitored by the PLC software.

The volumetric pump

The two components (H and R) are transferred to the MX-ST according to the required volumetric ratios via a high-precision volumetric pump. The volumetric pump manufactured by Silmek is the most technologically advanced product currently available, as it is able to maintain the exact required ratios even with different viscosity values of H and R and at various capacity levels. The pump ensures constant ratios with capacities of 1 kg/min and 8.5 kg/min.

The advantages of the static mixer

The static mixer produced by SILMEK perfectly addresses the need to "pour slowly" and at the highest level of fluidity, as the resin is formulated at the very moment it is poured. In addition to this key function, the MX-ST offers other advantages listed below.

The MX-ST produces the formulated resin necessary to effectively fill the coils in the autoclave, rather than a theoretical calculated amount, which could be too large or too small, causing further issues. There will be no difficulties if the pouring process needs to be stopped after identifying leaks in the molds; with the third mixer system, on the contrary, large amounts of formulated resin would often have to be evacuated and disposed of.

The MX-ST produced by SILMEK provides a system with no resin residues. This ensures that no waste is ever produced.
