Permanent moulding collection of release agent emissions

Permanent moulding collection of release agent emissions 

The spraying of a water-based release agent on HPDC dies generates a mist with low concentrations of decomposition products. The mist is collected using a suction hood and an EP. 

Reduction in the emission of release agent containing organic compounds. Prevention of diffuse emissions. 

Capture and collection of the mist requires the consumption of energy. 

Operational data from an example plant are given in Table 4.52. The data refer to a water miscible release agent (1 40 dilution factor), based on synthetic polymer and polysiloxane. Each die-casting machine is equipped with a separate suction hood and an EP. The hot and cleaned air is blown back into the hall (i.e. for heat recovery).
