An arrangement for melting at least one solid precursor product for polymer production includes a housing for receiving the solid precursor product by way of an opening, and a melting device arranged in the housing. The melting device is disposed so that the solid precursor product can be fed thereto to be melted. A preferably switchable discharge device is connected to an opening of the housing and can be connected to an injection unit.

Melting and injection device for plastic materials

Provided is a temperature control device having at least one temperature control branch connected to a feed, and a pump system including at least one pump for the delivery of temperature control medium in the feed. Additionally, the temperature control device is provided with at least one sensor by which at least one of the parameters from the group of temperature, through-flow amount and pressure can be detected, and a control or regulating device for regulating or controlling a delivery of the pump system, to which signals from the at least one sensor can be fed.

Method for temperature control of a shaping tool

An injection molding method in which plastic material under pressure is injected from a storage chamber with a closable outlet into a mold cavity and fills same under pressure, wherein the volume of the storage chamber and the pressure obtaining therein upon opening of the closure means are of values which are sufficient for filling of the mold cavity by expansion of the material in the storage chamber, and the storage chamber is arranged in the mold forming the mold cavity.

Injection moulding method

An apparatus for the injection molding of plastic material, comprising a mold ( ) into which molten plastic material is introduced, wherein there is provided a device for introducing liquid, in particular water, into the interior of the molten material, which includes a pump ( ) driven by a motor ( ), wherein the speed of rotation of the motor ( ) and/or the stroke volume of the pump ( ) is variable.

Apparatus for the injection molding of plastic material

A method of processing plastic material, wherein the plastic material is pressure-lessly distributed over the lower mold half of a mold divided in a horizontal plane, then the mold is closed and the mold cavity is entirely filled with molten material whereupon a fluid is injected into the molten material and a portion of the molten material is displaced into a secondary cavity by the fluid.

Method for processing plastic material

Method of controlling a machine for the manufacture of products, in

A method for supplying a selected quantity of gas to the mold of an injection molding machine utilizes two high pressure gas bottles which are connected through a pressure reducing valve to a piston reservoir for receiving a quality of the gas. The piston reservoir is hydraulically powered to supply the gas to a further piston reservoir having a smaller volume which is connected through a valve to the mold. The second piston reservoir is also hydraulically powered for supplying a selected quality of gas under a variable pressure to the mold. Gas from the mold is recycled to both reservoirs in steps.

Injection molding process with pressure increasing mechanism

A process for tempering tools, for use on the form tools of extrusion forming machines. In the injection molding tools there are conduction circuits for a coolant which are connected to ducts for the inflow and backflow of the coolant. Valves (4) control the throughflow of the coolant. There are temperature sensors (5, 6) in the ducts for the inflow and backflow of the coolant. The temperature sensors (5, 6) are connected to a computer (7) which controls the opening and closing times of the valves (4) as a function of a nominal difference fed in between the inflow and backflow temperatures of the coolant. Advantageously, a temperature sensor (3) which is also connected to the computer (7) is provided on the form tool.
