DESMA direct soling offers plenty of advantages having positive effect on both shoe manufacturing as well as product quality! Developed by DESMA the Particle Dosing Unit (PDU) enhances these advantages by the aspect of sustainability since granuled PU, TPU or Rubber production wastes may flexibly be added to and used in the known injection process. 

Either via retrofitting or when investing in a new machine the Particle Dosing Unit (PDU) enables you to add a maximum of 20% in solid particles to your shoes midsoles. This results in reducing the use of virgin chemicals, enables a re-use of production waste and thus activley contributes to your manufacturing sustainability when industrially manufacturing shoes. Used by many shoe manufactures - also manufacturing safety- and protection footwear - the Particle Dosing - Technology summarizingly supports you in: 

1. Re-use your production waste in your running production

2. Add granules / particles to your virgin chemicals to reduce the amount of virgin chemicals needed

3. Reduce the amount of production waste sent to landfill / thermal recycling

4. Reduce the need in virgin chemicals

5. Improve your CO2 footprint

6. Benefit from a flexible use of the Particle Dosing Unit (PDU) - neither your material tanks nor your piping system is contamined by granules as the dosing is positioned directly at the mixing chamber.
