摘要： A method for making an object (2) from plastic material, having a wall (21) and a through hole (22) formed in the wall (21), comprises the following steps: preparing a dose (20) of extruded plastic material; preparing a mould (1), having a first half mould (11) and a second half mould (12), mutually movable along a longitudinal axis (A1), wherein the first half mould (11) includes a body (111) and a plunger (112), the plunger (112) being movable relative to the body (111) between a retracted position and an advanced position; positioning the dose (20); closing the mould (1) to form a closed moulding space (V); moving the plunger (112) from the retracted position to the advanced position to squeeze the dose (20) so that the plastic material is forced to occupy the moulding space (V).

摘要： Provided is a sizing apparatus including: a die set including a die plate that holds a die provided with a through hole to which a workpiece is to be supplied, and upper and lower punches that are to be inserted into the through hole to press the workpiece; a press main body that includes punch driving mechanisms that actuate the punches and in which the die set is configured to be attached to and detached from a predetermined position; and a turntable that is rotated on the die plate and supplies a workpiece to the die and discharges a workpiece from the die. The die set includes the turntable, and a supporting base on which the turntable is placed. The supporting base includes an axis positioning portion that is provided coaxially with a central axis of the turntable and positions the central axis at a predetermined position of the supporting base.

摘要： A distributor device is arranged for controlling a plurality of actuators, each of which is intended to open or close a corresponding mould.
The distributor device comprises a rotary part rotatable about an axis and connectable to the actuators, and a stator part in fluid communication with the rotary part.
The stator part is provided with: a low pressure distributor element, configured to selectively send an actuating fluid at a first pressure to the rotary part, so that one actuator of the plurality of actuators moves a first component and a second component of the corresponding mould closer to each other from a distanced position to an intermediate position; a high pressure distributor element, configured to selectively send an actuating fluid at a second pressure higher than the first pressure to the rotary part, so that the actuator moves the first component and the second component of the corresponding mould closer to each other from the intermediate position to a forming position; a maintaining distributor element, configured to selectively send an actuating fluid to the rotary part, so that the actuator maintains the first component and the second component in the forming position.-

摘要： An apparatus comprises: a dispensing device for dispensing at least one polymeric material; a severing element for severing a dose of polymeric material from the polymeric material dispensed by the dispensing device; a transport element for transporting the dose; a mould comprising a male mould element and a female mould element, the female mould element being positioned above the male mould element. The transport element is configured to perform a first movement by moving along a path directed from the dispensing device towards the mould, so as to bring the dose to the mould. Moreover, the transport element is configured to perform, in addition to the first movement, a second movement by rotating about an axis, so as to turn the dose from a first orientation with which the dose is received by the transport element, to a second orientation with which the dose is released by the transport element onto the male mould element.

摘要： The invention relates to a feeding carriage for a compressor machine of the type having an upper filling end through which a particulate material which is to be compressed in a mold of the compressor machine is introduced, and a lower discharging end for discharging said particulate material towards said mold. At least some of the elements forming said feeding carriage can move with respect to one another, which thereby allows modifying the geometry of at least one of said lower discharging end, said upper filling end and an intermediate portion of the supply carriage located between both ends. The invention also relates to the use of such a feeding carriage comprising the initial steps of determining optimum carriage geometry for a particulate material which is to be compressed and applying said optimum carriage geometry to the feeding carriage.
