A fluid material ejecting apparatus includes a material chamber to which a fluid material containing at least one of metal particles and ceramic particles is supplied, a valve seat constituting a part of the material chamber and including an ejection port, a piston movable in the material chamber in directions toward and away from the ejection port, and a driver of the piston. The driver is configured to cause the piston to contact the valve seat from a position away from the valve seat and move in the direction toward the ejection port so as to slide along the valve seat, to thereby eject the fluid material through the ejection port. Sliding surfaces of the piston and the valve seat via which the piston and the valve seat contact each other have a higher Vickers hardness than the particles contained in the fluid material.

Apparatus and methods for storage and transmission of recipe data (process parameters) for the molding of articles in an injection molding apparatus. A controller includes a flow control microcontroller (MCU) that receives recipe data from a recipe storage microcontroller (MCU) mounted to a mold of an injection molding machine, the recipe storage MCU storing the recipe data defining process parameters for the molding of articles in the mold. The flow control MCU executes instructions for controlling valve pin motions according to the recipe data. In one embodiment, a human operator interface is provided for transmitting data to and/or from at least one of the recipe storage and flow control MCU's, allowing the operator to monitor, modify and/or control the process parameters during a molding cycle and/or to create a modified or new recipe for subsequent storage on the recipe storage MCU.

A geopolymer brick fabrication system comprising a mixer (100) having a tank (101) which comprises a closeable bottom outlet (102) and an inner surface coated with saturated polyester resin that is resistant against corrosive geopolymeric material for receiving the geopolymer raw material to be mixed by shaft (103) driven by a spindle motor (104) a molding section (200) to receive the mixed geopolymer raw material through a slanted conveyer (105) upon opening of the closeable outlet (102) for shaping the mixture under pressure inside a mold (201) to obtain a geopolymer brick and a curing section (300) having a moving platform (301) across a curing chamber (302) to simultaneously cure and transport the brick thereon.

The present invention relates to a food-forming-apparatus with: a rotating drum (5) which comprises product cavities in which a food product is formed from a food mass and a food mass feed member (23), which comprises a housing with an infeed channel (24) and at least one upstream sealing area (25) and/or a downstream sealing area (26) and a flexible pressure plate (7) which is pressed against the outer surface of the drum and thereby provides a seal between the food mass member and the drum. The drum has at its outer surface a multitude of rows of cavities.
