Deicing Device and Method of Manufacture
An ice melting device formed into an impact dispersion projectile for melting ice. The projectile being formed of salt and other ice melting chemicals. The ice melting compound is mixed, placed into a jig, dipped into a combination of liquid detergent and water then drained, compressed, heated, and then cooled. The projectile may then be removed from the jig and packaged. The projectile may be thrown by an individual onto an ice coated surface where the projectile upon impact will disintegrate and disperse the ice melting salt and ice melting chemicals onto the ice coated surface initiating the melting of the ice.
Method and apparatus for preparing rare earth sintered magnet
A mold comprising a die, an upper punch, and a lower punch, the pressure surface of one or both of the upper and lower punches being shaped non-planar, a cavity being defined between the die and the lower punch, is combined with a feeder including a shooter provided with a main sieve at its lower end port, the main sieve having a sifting surface of substantially the same non-planar shape as the pressure surface. A rare earth sintered magnet is prepared by feeding an alloy powder into the cavity through the shooter and sieve while applying weak vibration to the shooter, applying a uniaxial pressure to the alloy powder fill in the cavity under a magnetic field to form a precursor, and heat treating the precursor.
Punching Tool of a Sintering Press and Method Therefor
The present invention relates to a punching tool of a sintering press, comprising at least one lower punch and an upper punch, a first punch of the upper punch and/or lower punch having a top piece that is asymmetric with respect to an axial axis of the punch press. The first punch has a geometry which widens from the top piece towards a base and is also asymmetric with respect to the axial axis of the punch press. The invention further relates to a method for pressing at least one powdery material to a green body in a sintering press.
SYSTEMS AND METHODS FOR THE FABRICATION OF TABLETS, INCLUDING PHARMACEUTICAL TABLETS
Systems and methods for fabricating ingestible pharmaceutical tablets are provided. Certain of the systems and methods described herein are capable of manufacturing tablets of different dosages without the need to fluidically connect or disconnect unit operations when switching from a tablet having a first dosage to a tablet having a second, different dosage. Certain of the systems and methods described herein are capable of manufacturing compositionally tablets, e.g., tablets with different active pharmaceutical ingredients (APIs).
METHOD AND DEVICE FOR PRODUCING HARD-METAL PRESSED ARTICLES
A method for manufacturing hard-metal pressed articles includes providing a die that forms a cavity for producing a pressed article with at least one cutting edge and at least one chip breaker groove that is associated with a chip space. The step of providing the die providing a movable mold part and a movable mold body. The mold part has an operative surface, wherein the mold part at least sectionally defines the shape of a pressed article with the operative surface, and wherein the mold part is feedable in a first feed direction. The mold body has a rod-shaped operative section for producing a through-hole in the pressed article, wherein the mold body is feedable in a second feed direction. The first feed direction and the second feed direction are inclined at an angle of at least 45? to each other. The pressed article is formed from a hard-metal powder that is introduced into the cavity and compressed there in at least one main pressing direction. Forming the pressed article comprises feeding the mold part and the mold body such that the mold body is positioned in the cavity with the operative section being disposed in an abutment area on the mold part in a powder-tight relative position. A device enables the manufacture of hard-metal pressed articles.
Sintering Press With Axially Controlled Deformation, and Corresponding Method
The invention relates to a sintering press which comprises at least one upper punch and a lower punch, a powder reservoir for filling a female die of the sintering press with at least one powder material that can be sintered, and a female die for producing a green body using the powder material from the powder reservoir. A first punch of the upper punches and/or lower punches has a punch top which is off-center and asymmetric with respect to an axial axis of the sintering press and which can be moved in the female die along a female die outer wall and/or along an adjacent punch without being guided inside the female die. The first punch is asymmetric in shape between the punch top and the base, which shape at least reduces an axial tilting of the punch and a lateral drag of the punch top on an adjacent outer surface in the female die, in particular prevents such tilting and dragging, during insertion and extraction therefrom during a pressing step in the production of the green body.
MINI HOT PRESS APPARATUS
The present invention relates to a mini hot press apparatus, and more particularly, to an apparatus which can be used for making or annealing a polycrystalline material by pressurization and heating in various surrounding environments such as in a low vacuum, high vacuum, ultrahigh vacuum, high pressure gas, gas flow, even in air, etc.
Method for producing rare earth sintered magnet
The present invention provides a method for producing a long and large-sized rare earth sintered magnet having a large size in a magnetic field application direction in which a single magnet body in each portion has uniform and high magnetic characteristics. Disclosed is a method for producing a rare earth sintered magnet, including particular steps of: 1) preparing a slurry; 2) preparing a cavity that is enclosed with a mold, an upper punch and a lower punch; 3) applying a magnetic field of 1.5 T or more in the cavity, and supplying the slurry at a flow rate of 20 to 600 cm.sup.3/second, to fill the cavity with the slurry; 4) producing a molded body of the alloy powder by press molding in the magnetic field; and 5) sintering the molded body.
Method and device for manufacturing a cutting insert green body
A method and device for manufacturing a cutting insert green body, the method includes the step of providing a compression tool having an upper and lower die, and an upper and lower punch. The upper die defines a punch tunnel in which the upper punch slides, and the lower die defines a punch tunnel in which the lower punch slides. The dies define a die cavity to accommodate a powder to be compressed by action of the respective punches to form the green body. Powder in the die cavity is compressed by forwarding the upper punch through the punch tunnel of the upper die and a predetermined distance L through the opening of the lower die. The upper die is displaced relative to the opening of the lower die and the upper punch is removed from the lower die to move the green body out of the lower die through the opening thereof.
Tooling assembly for powder compacting press machine
A tooling assembly is for a powder compacting press machine, which has a lower punch chuck and a core rod chuck. The tooling assembly has: a lower punch with a lower punch drawbar for holding the lower punch in the lower punch chuck in the powder compacting press machine; a core rod with a core rod drawbar for holding the core rod in the core rod chuck in the powder compacting press machine; and a coupling mechanism configured to enable a connection between the lower punch and the core rod. The coupling mechanism has a male coupling element on an outer surface of the core rod and a female coupling element on an inner surface of the lower punch drawbar. The male coupling element is an elastic element.
