Especially, method of the present invention comprises following operating procedure:
Be deposited on the conveyer belt by being arranged on apart from the pantostrat of described device with an adjustable distance with powder, described device is used for described powder bed is scraped the thickness of an expectation;
Described band is advanced in such a way by the first pressurization station of a continous way, so as in the process of advancing of described band the described powder of compacting, to obtain the goods of the bonding of the powder of pre-compacted under predetermined constant pressure;
After described compacting, measure the thickness of powder bed;
Continuous control is fed the distance of that side of outlet apart from band as the powder of powder bed curette, the thickness of the powder that is transmitted by described band subsequently with control.
According to the present invention, the described first pressurization station can or the first pressurization station, this first pressurization station only is suitable for making described powder bed bonding, carries out second and last pressurization then; Perhaps can constitute unique pressurization and compacting station.
Under first kind of situation, be used for must preferably reaching a maximum gradually at the pressure of the described material of the first pressurization station compacting, this maximum is at 20kg/cm 2And 100kg/cm 2Between, and preferably at 30kg/cm 2And 70kg/cm 2Between.Under second kind of situation, the pressure that described material bears must preferably reach one at 300kg/cm 2And 450kg/cm 2Between maximum.
The present invention also comprises a kind of equipment that is used to carry out preceding method.
Described equipment comprises a conveyer belt, forms the pantostrat of a dusty material on described conveyer belt; And comprise be used for described with on laterally keep the device of described material; The continuous pressue device of band forms, its make described with on powder bed can under predetermined constant pressure, be compacted, with the goods of the bonding that obtains pre-compacted powder; And the device that is used for when described first pressurized operation finishes, measuring described products thickness.
The described device that is used to measure described products thickness is preferably linked together with a processor, and the distance of apparatus to described band scraped in described processor control.
The described device that is used for measurement products thickness when first pressurized operation finishes can comprise common measuring transducer, and perhaps any other is applicable to the device of this purpose.Instead, be used to control that to feed that side of outlet as the powder of curette be common mechanical type micromatic setting to the device of the distance of described band, for example operate the motor that the control of sun-negative thread composite set is advanced.
Further aspect of the present invention is limited in claims.
