The disclosure relates to an atomizer for the application of a multi-component paint, with a master paint connection, a hardener connection, a mixer, a hardener line leading in the atomizer from the hardener connection to the mixer, a master paint line, which in the atomizer leads from the master paint connection to the mixer, and with a main valve for controlling the paint delivery, the main valve being arranged downstream of the mixer and controlling the flow of the multicomponent paint to an application element, in particular to a rotatable bell cup. The atomizer according to the disclosure is characterized by a first return connection for returning the multicomponent paint from the atomizer to a return system. For this purpose, the atomizer has a first return line which branches off in the atomizer between the mixer and the main valve and opens into the first return connection.

A method to dispense fluid products is implemented in a dispensing machine by combining gravimetric and volumetric dispensing techniques which comprises at least one containing unit to contain at least one fluid and equipped with a dispensing mean, a dispensing station comprising a dispensing head fluidically connected to the containing unit and equipped with at least one dispensing nozzle, a user interface to enter input data for the preparation of a fluid product, and a control unit connected to the user interface and to the dispensing mean of the containing unit so as to command the dispensing of the fluid.

A machine (10) to automatically prepare a fluid coloring product inside a container (15), which can already contain a base product, comprises a loading station (26), a perforating device to make an aperture in the upper part of the container (15), a delivery device (21) configured to deliver coloring substances inside the container through such aperture, and a closing device configured to automatically closed such aperture with a closing element, after the delivery of the coloring substances.

An automatic line for producing paints and the like wherein a dispensing of the bases and colorants is programmed so as to dispense in an order a first base, a dose of colorant and a second base inside a retail container, so that before mixing, the colorant is confined between two bases and there is no risk of part of the colorant adhering to an inner face of the lid without participating in the mixing.

A coating composition system for weighing and formulating coating compositions comprises a physical enclosure enclosing an electronic coating composition networking device. The electronic coating composition networking device comprises a local communication interface configured to receive a physical connector from an electronic scale and a network communication interface configured to communicate with an internet gateway. Additionally, at least one sensor may be integrated within the electronic coating composition networking device. The electronic coating composition networking device also receives, through the local communication interface, a mass variable from the electronic scale and a sensor variable from the at least one sensor. The electronic coating composition networking device then generates a network data structure comprising the sensor variable and the mass variable. The electronic coating composition networking device communicates, through the internet gateway, the network data structure to a remote server.

A paint packet-making apparatus may include a plurality of containers configured to contain one or more base paints and one or more tints, a sachet packaging apparatus, and a precision dispenser configured to work in concert with the sachet packaging apparatus and fluidly connected to the plurality of containers to selectively dispense the one or more base paints and the one or more tints into respective sachets to produce at least one custom paint sample with a volume of 125 mL or less.
