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.

An injection molding apparatus has a mold tool that is positioned around a field joint of a pipeline to define a mold cavity. Two or more pumping chambers communicate with the mold tool. Each chamber is expansible to draw in molten polymer and contractible to drive the polymer into the mold cavity. Expansion of one chamber is synchronized with contraction of another chamber. The operation of supply and injection valves associated with the chambers is also synchronized, both with each other and with expansion and contraction of the chambers. In the embodiment described, two pumping chambers are defined within a common pressurizing cylinder, in which the chambers are separated by a piston. The piston is movable within the cylinder to determine and to synchronize expansion and contraction of the chambers.

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.
