A method for producing an abradable seal for a turbomachine, such as a turbojet engine low-pressure compressor. The method comprises the following steps performed as follows: (a) preheating of a metal mould in a furnace; (b) filling of the hot mould with a powdery aluminium-based mixture; (c) degassing of the mixture in the mould; (d) compacting of the mixture in the still-hot mould at ambient temperature, so as to solidify the mixture in the mould. The abradable seal is thus produced in angular segments that form tiles. The angular segments are then bonded into a composite casing of the turbomachine.

A food baking apparatus includes a compressible die and a mechanical stop for controlling a die spacing of the compressible die. The mechanical stop includes a supporting system and a mounting element mounted onto the supporting system. The mounting element includes at least one protrusion having a particular amount of protrusion from the mounting element, which amount of protrusion may be adjustable for any single protrusion. By translation or rotation of the supporting system and/or the mounting element during operation of the apparatus, a protrusion is selected. The protrusions mechanically stop further compression of the dies during an operation of the food baking apparatus. Thus, the selection determines the die spacing applicable for the baking process, based on the amount of protrusion of the selected protrusion.

A powder feeding device configured to fill a saggar with powder by compressing the powder thereinto may include: a pressing plate configured to compress the powder in the saggar; and a pressing mechanism configured to press the pressing plate toward the powder in the saggar. The pressing plate may include a compression plate including a pressing surface that compresses the powder by contacting the powder; and a plurality of slit plates disposed on the pressing surface and extending downward from the pressing surface. The slit plates may be arranged radially as the powder feeding device with the saggar placed therein is viewed from above. When the saggar is placed in the powder feeding device, distances between the slit plates and a sidewall of the saggar may be substantially equal and the distances between the slit plates and the sidewall of the saggar may be 30 mm or less.

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.

A press tool and a method for forming a cutting insert green body. The press tool includes a first and a second core rod. Both core rods are movably arranged along an axis. When both core rods are in a press position, their respective contact surfaces contact each other and when both the first and second core rods are in a release position, their respective contact surfaces are separated. The first core rod includes a base body having a forwardly facing abutment surface and a piston having a shaft and a head. The piston is movable to a plurality of extended positions and to a retracted position, in which the abutment surface of the head abuts against the abutment surface of the base body. When both the first core rod and the second core rod are in their respective press positions, the piston is in the retracted position.

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.

An apparatus for manufacturing an article from powder material including a first table, a second table rotatably mounted on the first table about a first axis and a third table rotatably mounted on the second table about a second axis. A hollow canister is supported by the third table. A vibrator is arranged to vibrate the canister. A first device is arranged to rotate the second table about the first axis and a second device is arranged to rotate the third table about the second axis. A hopper is arranged to supply powder material into the canister and a valve controls the flow of powder material from the hopper into the canister. A processor is arranged to control the valve, the vibrator, the first device and the second device to control the filling and packing density of the canister.

A rotary tablet press having a rotatably driven rotor and a die plate with a plurality of die bores. A plurality of upper and lower punches are configured to produce tablets in the plurality of die bores. The tablets are monitored for one or more characteristics and are sorted by an ejection apparatus according to the one or more characteristics into a reject channel and a satisfactory channel.

A split-die press tool for forming, by compressing a powder, a green body for a double-sided and double positive cutting insert for metal cutting. The tool includes a die with at least two die sections having a punch tunnel formed therebetween, an upper punch unit and a lower punch unit. When the lower punch unit is in a distal position a front end periphery of the lower punch unit is at a first expansion level corresponding to a maximal downward vertical decompression expansion of the green body to be formed. The punch tunnel has a first side surface portion on at least one of the die sections that has a vertical extension downward from the first pressing level to the first expansion level and is inclined downward and away from the pressing axis by an angle of at least the angle of an adjacent inclined lower surface of the green body.
