An injection molding system includes: an injection molding machine where a shaping mold is installed; a material supply device supplying a material to the injection molding machine; a temperature controller controlling a temperature of the shaping mold; a dryer drying a material stored in the material supply device; a controller controlling the injection molding machine; and a casing. The injection molding machine, the material supply device, the temperature controller, the dryer, and the controller are provided inside the casing. The casing has a caster and is configured to be movable.

A method of determining a target value of a state variable includes preparing a mixture of the molding material and the gas with different test values of the state variable, and the mixture is respectively compressed or decompressed. In the compression or decompression step, the state variable of the mixture and/or a further state variable of the mixture is measured directly or indirectly, and determination values of a compression behavior variable characteristic of the compression behavior of the mixture are determined from the measurement values. A criterion directed to a solution state of the gas is checked, and a lowest or highest value of the state variable is deduced at which the gas is in solution in the molding material. The lowest or highest value of the state variable at which the gas is in solution in the molding material is used as the target value.

A temperature sensor used in a molding machine is provided. The temperature sensor comprises a cylindrical fiber probe through which an optical fiber is inserted; an outer housing having a shaft, into which the fiber probe is inserted to be displaceable in an axial direction; a protective window disposed on a tip end side of the fiber probe and configured to protect a tip end of the fiber probe; and an elastic member that presses the fiber probe toward the protective window.

A method for producing a three-dimensionally shaped trim part of a motor vehicle, which has a visible side and a mounting side. A flowable material is injected with pressure into a chamber of an injection molding tool, which has at least two mold shells, which, when assembled, form the chamber with a negative mold of the trim part, wherein at least one first of the mold shells forms the visible side and at least one second of the mold shells forms the mounting side of the trim part. The material is hardened in the chamber. A gas pressure is generated that acts in a planar manner between the second mold shell and the material during the hardening. The hardened material is removed as a trim part from the chamber of the injection molding tool.

In one example, an apparatus for jointing power cables includes a mold extending along a longitudinal axis, and having a feeding inlet and being made of two halves forming a longitudinal pass-through seat for receiving the cables. An extruder is connected to the feeding inlet. A heating system and a cooling system is associated with the mold. A measuring system for detecting temperature or pressure includes a plurality of probes for detecting temperature or pressure.

According to one embodiment, a mold includes a substrate clamping surface, a cavity, a suction part, a vent, an intermediate cavity, and an opening/closing part. The substrate clamping surface contacts a surface of a processing substrate. The cavity is recessed from the substrate clamping surface. The suction part is recessed from the substrate clamping surface. The vent is provided on a path between the cavity and the suction part, communicates with the cavity, is recessed from the substrate clamping surface to a vent depth. The intermediate cavity is provided between the vent and the suction part on the path, communicates with the vent, and is recessed from the substrate clamping surface to an intermediate cavity depth deeper than the vent depth. The opening/closing part opens and closes the path and is provided between the intermediate cavity and the suction part on the path.
