The doser heads are devices in stainless-steel or anodized aluminum, which receive waxes and cosmetic pastes in a liquid or pasty state from a melting tank and pour them onto a cooling surface or directly into the final containers. In order to keep the material at the correct temperature, so as to ensure that it maintains the right level of viscosity, they are heated with electric resistances; the connection to the melting tank is obtained either directly or through a connection hose, which can also be heated to avoid creating alterations in the product during processing. The valves are made of stainless steel or polymer.
Both the temperature level and the size and timing of the doses are completely adjustable by the user; patented weights dispensers are also available to keep the actual dose of product delivered throughout the entire production cycle constant, and with continuous recirculation of the product to avoid separation and sedimentation of the components; where necessary, internal pressurization is possible to facilitate the output of particularly dense products.
