OSV M MDI machine is designed for automatic dosing, mixing and pouring of three-component polyurethane elastomers based on MDI or the so-called quasi-systems (Quasi MDI). The main feature of the unit is easy change of hardness of parts in a wide range from 45o Shore A to 70o Shore D

The OSV M MDI casting machines allow to process three-component polyurethane systems based on MDI and easily change the hardness of parts in the range from 45 ° Shore A to 70 ° Shore D by pressing one button on the operator panel.

The machines has a wide range of basic functions that allow you to fully automate the task of dosing and mixing the components of a rather complicated polyurethane system MDI, and to obtain high quality finished products by free casting in open and closed molds:

  • Special software with the ability to adjust and monitor all operating parameters of the equipment, including the ability to save recipes set by the operator
  • Real-time flow control and ratio correction with volumetric meters
  • Automatic adjustment of the ratio when choosing the hardness of the poured mixture
  • Controlled heating and thermal insulation of the entire dosing line from the tanks to the mixing head
  • Recirculation of components and mixing to ensure homogenization and thermal stabilization
  • Vacuum system to remove air inclusions in components and ready-mix
  • Automatic and manual mixing chamber cleaning system

A wide range of additional options and devices will allow you to adapt the equipment in accordance with the requirements of the client’s production process.
