A temperature control system and method for regulating a liquid temperature in a recirculation system of a molding system includes determining an operating pressure of the liquid in the recirculation system, determining an operating temperature of the liquid in the recirculation system, receiving the operating pressure and the operating temperature, comparing the received operating temperature to a threshold temperature as a function of the operating pressure, and adjusting an output of a heat exchanger in the recirculation system when the operating temperature is beyond the threshold temperature.

A device and a method for the thermal reshaping of hose blanks from preferably pre-extruded elastic raw hose material, wherein during the reshaping, the hose blank is arranged in a shell-like, single- or multi-piece molding tool with a hollow body, wherein the tempering of the molding tool that is necessary for reshaping occurs by means of clamp-like tempering elements which are shaped congruently to the outer surface of the mold and which close form-fittingly over the mold, while the molding tool itself does not comprise any tempering system at all, in particular no ducts or other hollow spaces for circulating a tempering medium, and wherein the temperature of each tempering element is kept constant during the process, while, to modify the temperature of the molding tool, a different tempering element with a correspondingly constant temperature is positioned against the molding tool.

Evaporative cooling system (1) having a closed fluid circuit operating at below atmospheric pressure to remove heat from a mould assembly (3). The system (1) includes a cooling fluid supply source (5) connected to a mould assembly (3) to supply cooling fluid in liquid phase to hollow cooling chambers (13) of the mould assembly (3). Heat is removed by evaporation of the cooling fluid upon contact with the internal wall surfaces (29) of the cooling chamber (13). The rate of heat removal is regulated by controlling flow of fluid and/or pressure within the system in response to a) temperature measurements in the mould assembly (3), and/or b) pressure measurements with the fluid circuit, such that the cooling chamber (13) remains substantially free of cooling fluid in the liquid phase with cooling fluid entering the chamber (13) evaporating upon contact with the internal wall surfaces of the chamber (13).

According to one implementation, a molding equipment of a composite material includes a vessel, a decompression system and a heating medium supply system. The vessel houses a molding target sealed by a sealing object. The decompression system performs bending forming of the molding target and pressurization on the molding target after the bending forming by decompressing a region surrounded by the sealing object in the vessel. The heating medium supply system supplies a heating medium into the vessel. The heating medium is supplied for the bending forming, and heating and curing of the molding target under the pressurization.

A support form defining a longitudinal axis is provided. The support form includes a first section, a second substantially solid section, and at least one flow feature form. The first section includes a plurality of unit cells of a first material joined together to form a lattice. The second section includes a second material and surrounds the first section. The at least one flow feature form is defined in the second section and is configured to generate a flow feature on a heat exchanger tube formed by plating the support form.

A vessel manufacturing method includes placing a bag-shaped, film-based vessel on a placement stage with concave portions formed on the stage, introducing fluid into the vessel placed on the stage, and pressing the vessel which is placed on the stage, by a pressing member while heating at least one of the stage and the pressing member. Meanwhile, a cell culture vessel includes a first vessel wall as a bottom wall and a second vessel wall. The first vessel wall is formed of a flat film having gas permeability. The second vessel wall is disposed in contact with a peripheral edge portion of the first vessel wall, and has a bulge shape protruding relative to the first vessel wall. The first vessel wall is flat at its section other than a region where the first vessel wall is in contact with at least a charge/discharge port.
