The method of filling a weighing container (10) for plastics granulate (12), wherein the granulate is dropped from a supply tube (26) into the weighing container (10) via a shutter (22), wherein the weighing container (10) is closed-off on the top side by a wall having a conical part (16) that reaches directly up the shutter (22), and in that the weighing container is filled with granulate up to the level of the shutter (22).

A machine for dry decoration of ceramic slabs or tiles, comprising: a support element (10), provided with a plurality of cavities (11) with a pre-established shape; a dispensing device (20), configured to deposit a pre-fixed amount of powder material inside one or more pre-established cavities (11); an unloading device (30), configured to move the cavities (11) from a loading position, in which they can receive the powder material from the dispensing device (20), to an unloading position, in which they can unload the powder material.

A plasticizing device includes: a material storage unit having a charging port and configured to store pellet-shaped resin pellets; a plasticizing unit having a supply port in communication with the charging port and configured to plasticize at least a part of the resin pellets to generate a shaping material; a coupling pipe having a coupling path coupling the charging port and the supply port; a first material sensor configured to detect a remaining quantity of the resin pellets in the coupling path; and a control unit. The material storage unit includes a material supply mechanism configured to supply the resin pellets to the coupling path, and when the remaining quantity of the resin pellets detected by the first material sensor is less than a first reference value, the control unit controls the material supply mechanism to supply a predetermined quantity of the resin pellets to the coupling path.

The present invention relates to a method for changing material in an extrusion device comprising at least two supply devices for supplying feedstock for an extruder, comprising the following steps: identifying a change request for changing material in an extrusion device, predetermining a production stability for a time after the material of at least one supply device has been changed, comparing the predetermined production stability to a threshold value of stability, changing the material in at least one supply device depending on the result of comparison.

A dosage device for extruding a monocomponent or a bicomponent polymeric product, particularly for an automatic machine for forming a spacer frame, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the product, which can be activated, in a first feeding step and in a third feeding step, alternately so that one of them provides continuity of flow to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activated, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.

An LED is fabricated with a composite layer including quantum dots (QDs), wherein the QDs are provided in a silicone paste. A plurality of QD silicone paste reservoirs each contain a provided silicone paste with QDs of different wavelengths. Further, a silicone paste reservoir containing a clear silicone paste. A paste mixing chamber, in to which the QD paste reservoirs and the silicone paste reservoir supply their respective pastes, mixes together the pastes and form a mixed QD silicone paste. A silicone mixing and metering component receives the mixed QD silicone paste from the paste mixing chamber, and further receives A silicone and B silicone from a respective A silicone reservoir and a B silicone reservoir, measures, and mixes the mixed QD silicone paste with the A and B silicones to form a silicone polymer composite. A dispensing component receives to the silicone polymer composite from the mixing and metering component and dispenses the composite to a molding tool.
