Abstract
A moulding method and device for moulding products from a dose of molten material, wherein the movement of a part of the mould towards another part of the mould is controlled in position and the compression movement represents between 5% and 40% of the cycle time.
Claims15
A moulding method for moulding products from a dose of molten material, with a moulding device (1) comprising at least a dosing unit (30);
- at least one mould formed of at least a first part and a second part (13, 14);
- an electrical motor (4) that pilots a compression movement of at least one of said parts of the mould towards the other of said parts;
- a rotating turret (45);
- a spring (5) that defines a moulding force;
- wherein at least the electrical motor (4) and the dosing unit (30) are in a fixed position in the moulding device (1);
- wherein at least one of said parts (13, 14) of the mould rotates with the turret (45);
- the moulding method being characterized in that the movement of one of said parts (13, 14) of the mould towards the other of said parts (13, 14) is controlled in position and the compression movement represents between 5% and 40% of the cycle time.
