A conveying device for conveying a viscous material from a container includes a follower plate that can be inserted into the container, and a pump by means of which the viscous material can be conveyed through the follower plate. Moreover, a measuring chamber for accommodation of a measuring sample of the viscous material is provided. The measuring chamber includes a closable material inlet opening for this purpose. A closable disposal line leads away from the measuring chamber. Moreover, a closable material return line extends from the measuring chamber via the follower plate into the container. The conveying device also includes a controller that is designed and can be operated appropriately such that it determines the compressibility of each of multiple measuring samples. The controller opens the disposal line or the material return line to the measuring sample present in the measuring chamber as a function of the compressibility thus determined.

A control system and a control method of manufacturing injection molding products are provided. The control system includes an injection molding machine, an information input interface, a computing server and a data conversion device. At first, product information is inputted through the information input interface. The product information is transmitted to the computing server, and then the computing server determines injection molding parameters according to the product information. The injection molding parameters are transmitted to the information input interface. After data conversion through the data conversion device, the injection molding machine is controlled to manufacture the injection molding products according to the converted injection molding parameters.

Systems and approaches for controlling a molding machine having a mold forming a mold cavity, a nozzle, and a screw that moves from a first position to a second position toward the nozzle and being controlled according to a mold cycle. Injecting a molten polymer into the mold cavity and obtaining a first measurement of a variable during the injection cycle using a first sensor positioned at or near the screw. A second sensor positioned at or near the nozzle is used to obtain a second measurement of the variable during the injection cycle. A measured compressibility ratio value is determined in the form of a difference between the measured variable obtained by the first sensor and the measured variable obtained by the second sensor. The measured compressibility ratio value is compared with a reference compressibility ratio value and at least one control parameter is adjusted based on a difference between the reference compressibility ratio value and the measured compressibility ratio value.

A core molding apparatus and a core molding method capable of reducing the possibility of the deterioration in the calculation accuracy of the amount of supply of a raw material for a core are provided. A core molding apparatus includes: a kneading tank configured to knead a raw material for a core; a raw material supply unit configured to supply the raw material to the kneading tank; a mold configured to contain a kneaded material made of the raw material kneaded in the kneading tank and to mold the core; a piston configured to inject the kneaded material contained in the kneading tank into the mold; and a control unit configured to control an amount of supply of the raw material from the raw material supply unit to the kneading tank.

A flow rate adjusting device includes a main body portion including a supply flow path formed with a first opening through which a plasticized material obtained by plasticizing at least a part of a material containing a metal particle is supplied and a second opening through which the plasticized material is ejected, and an intersecting hole intersecting the supply flow path; a tubular sleeve disposed inside the intersecting hole and including a through-hole at a position overlapping the supply flow path; and a shaft-shaped valve unit disposed inside the sleeve, wherein the valve unit includes a concave portion at a position overlapping the supply flow path, and rotates inside the intersecting hole for changing a position of the concave portion, to change a flow path cross-sectional area of the supply flow path for adjusting a flow rate of the plasticized material ejected from the second opening.

A resin molding device includes: a lower mold on which a substrate is placed; an upper mold in which a cavity is formed by a side block and a cavity block provided so as to be capable of ascending and descending vertically with respect to the side block; a clamp mechanism which clamps the lower mold and the upper mold; a transfer mechanism which supplies a resin material to the cavity by a plunger; and a controller which performs first final adjustment control for adjusting a clamp load of the clamp mechanism to a final clamp load after the cavity has been filled with the resin material supplied from the transfer mechanism and which performs second final adjustment control for driving the plunger after the first adjustment control has been completed and thereby adjusting a plunger load applied to the plunger to a final plunger load.
