Embossed sheet and method of making and using same
A embossed sheet embossed with projections creating an intermittent support surface for food. The embossed sheet may be inserted into a food package after cooking the food on which the cooked food is to be supported. Alternatively, the embossed sheet may be placed onto or into a pan or directly onto an oven rack to support the food while cooking and/or after cooking. Alternatively, the embossed sheet may be formed into a food package. The embossed sheet may be prepared using a one-pass or two pass process using a platen press or a roll-to-roll press or a multi-stage one pass machine.
Cutting insert with internal cooling, mold and method for manufacture thereof
A cutting insert is provided, comprising a top surface, a bottom surface, a plurality of side surfaces spanning therebetween, and a cutting edge formed at an intersection of the side surface and a forwardly-disposed portion of the top the surface. It further comprises a cooling cavity projecting into the insert, a top end thereof being disposed further forwardly than an open bottom end thereof. The cooling cavity defines at least one molding axis such that a solid element having the shape of the cooling cavity and completely inserted therein may be retracted intact therefrom along a linear path parallel to the molding axis. A circumscribing portion is formed on the side surfaces encircling the cutting insert. The circumscribing portion is formed parallel to the molding axis and has a non-zero height along its entire extent. The cutting insert does not extend beyond the circumscribing portion.
High pressure carbide component with surfaces incorporating gradient structures
An anvil including a hard phase and a metal matrix in which the hard phase is dispersed, a concentration of the metal matrix phase varying according to a concentration gradient, is disclosed. The anvil may be used in a high pressure press. Methods of making an anvil including forming a hard phase dispersed in a metal matrix phase, a concentration of the metal matrix phase varying according to a concentration gradient, are also disclosed.
Method for producing a green compact using a pressing tool, a pressing tool, a green compact, and a sintered part
A method for producing a green compact uses a pressing tool including a die, a first punch to be displaced in an axial direction, a second punch to be displaced in a radial direction through a channel in the die and a receptacle having a filling opening. The method includes locating the second punch before or during filling of a powdery material into the receptacle so as to be outwardly offset in the radial direction relative to an inner peripheral surface, filling the powdery material into the receptacle, and moving at least the first punch and the second punch and compressing the material in the receptacle, with the second punch being moved in the radial direction toward the receptacle only so far that it is disposed flush with a region of the inner peripheral surface. A pressing tool, a green compact and a sintered part are also provided.
CUTTING PLATE AND METHOD AND COMPRESSION MOLD FOR PRODUCING A GREEN BODY OF THE CUTTING PLATE
A compression tool, a cutting plate and a method of producing a cutting plate by multiaxial pressing a powder mixture of a hard metal component and a binder to form a green body is provided. After pressing, the body has two parallel main surfaces and a peripheral edge surface extending between and connecting the main surfaces. The main surfaces include depressions, such that cutting edges are formed at the intersection of the bottom of the depressions and at least a part of the edge surface. A heading tool includes a main punch and an independently moveable form punch. In a first pressing step, the form punch is moved towards the powder mixture to form a preliminarily compressed portion. In a second step, the main punch and the form punch are both moved towards a final position to provide the green body with its final dimensions including the depressions.
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.
Device for pressing a non-hardened concrete composition and method for the manufacture of concrete articles
Device for pressing a non-hardened concrete composition into a desired form includes an upper plate with first cavities running through the upper plate, a moulding plate with one or more second cavities whereby the upper plate is located directly above the moulding plate, a bottom plate located under the moulding plate whereby the bottom plate closes the one or more second cavities on the bottom, whereby the upper plate and the moulding plate can move horizontally in relation to each other between a first position in which the one or more first cavities are directly and exactly above the one or more second cavities and a second position in which the one or more first cavities are not above the one or more second cavities, wherein the thickness of the upper plate and not the thickness of the moulding plate is decisive for the thickness of the final article.
Apparatus for manufacturing microtablets
Embodiments provide methods and apparatus for manufacturing a microtablet from a precursor material such as a pharmaceutical powder. Various embodiments provide a method which includes compressing the powder to form a compressed mass of a selected density and repeatedly compacting the compressed mass to increase the density of the compressed mass and form a microtablet. Related methods and apparatus are provided.
APPARATUS AND METHOD FOR FORMING MOLDED PRODUCTS
A press apparatus for forming molded products is provided and includes an motive source and a press assembly in fluid communication with the motive source. The press assembly includes a press plate and a device configured to actuate axial movement of the press plate as initiated by the motive source. A mold base is positioned within the press assembly and configured for engagement with the press plate. The mold base includes a plurality of mold cavities and each of the mold cavities includes a mold cavity aperture. Each of the mold cavity apertures is arranged in a pattern and configured to provide access to a molded product positioned in a mold cavity. A release assembly is configured for engagement with the mold base and has a plurality of release fingers, each extending from a base plate. The plurality of release fingers is arranged in a pattern that aligns with the pattern of the mold cavity apertures.
Hot-Pressing Tool Half, Hot-Pressing Device with A Hot-Pressing Tool and Method for Hot Pressing Preforms from A Fiber-Containing Material
A tool component, a hot-pressing device and a method for hot pressing preforms from a fiber-containing material are described, wherein the hot-pressing device has a first tool component with a first tool body and at least one first molding device and a second tool component with a second tool body and at least one second molding device. The method includes providing at least one preform made of fiber-containing material, heating the first tool body and the first molding device via a temperature control device, placing a preform on first contact surfaces of the first molding device, moving the second tool component relative to the first tool component, and pressing the first tool component and the second tool component until the first contact surfaces and the second contact surfaces form a closed cavity.
