Mixing head

Mixing head – RTM injection technology

The PZS-300M and 400M mixing head, controlled by the injection machine, optimizes the mixing of epoxy or polyester resins for both small and large flow rates.

Thanks to its advanced design, it is equipped with a recirculation system that prevents deposits in the piping and maintains product pressure to ensure consistent and efficient injection. At the end of the cycle, the distributor shaft pivots to automatically activate recirculation and rinsing, simplifying maintenance.

Key strengths:

  • Homogeneous and reliable mixing of resins

  • Built-in recirculation function to prevent clogging

  • Automated rinsing for fast and effective cleaning

  • Suitable for small and large series production

  • Reduced downtime and optimized productivity

Applications:
Ideal for RTM processes in the aerospace, automotive, marine, renewable energy, and general industry sectors, the PZS-300M/400M mixing head guarantees consistent manufacturing quality and high durability.
