Provided is a hot-working tool capable of maintaining adequate toughness even if the permissible amount of P contained in the hot-working tool is increased. The present invention is a hot-working tool, which has a component composition that can be adjusted to a martensitic structure by quenching and has a post-quenching and tempering martensitic structure, wherein: the component composition comprises greater than 0.020 mass % to 0.050 mass % of P; prior austenite grain diameter in said post-quenching and tempering martensitic structure is at least No. 9.5 in grain size number according to JIS-G-0551; and the P concentration of the grain boundary of said prior austenite particles is not more than 1.5 mass %. A hot-working tool wherein said component composition also comprises not more than 0.0250 mass % of Zn is preferable. The present invention also is a method for manufacturing a hot-working tool in which quenching and tempering are performed on a hot-working tool material with said component composition.

Provided is an injection molding system that makes it possible to maintain convenience while improving safety. The injection molding system comprises an injection molding machine, a peripheral device used in combination with the injection molding machine, and an operation device that is for operating the injection molding machine and the peripheral device and that can be separated from the injection molding machine and the peripheral device and moved. The operation device includes a first operation part for operating the injection molding machine 2, a second operation part for operating the peripheral device, an operation-permitting part that permits operation of the injection molding machine by the first operation part or operation of the peripheral device by the second operation part, and an operation control unit for controlling operation of the injection molding machine and the peripheral device by the first operation part, the second operation part, and the operation-permitting part.

The invention relates to a method for producing a hollow injection-moulded part, in particular a primary packaging means for medical applications by an injection moulding method, comprising the following method steps: a) Providing a first female die tool having a first mould cavity and a mould core formed as a male die tool; b) Introducing a mould core into the first mould cavity so that a first cavity is formed and the mould core extends beyond the mould cavity in the axial direction (X), thereby bringing the mould core into operative contact with the first female die tool and/or with a receiving member; c) Injecting a first plastic material into the first cavity so that a first portion of the injection-moulded part is formed; d) Transferring the first portion of the injection-moulded part to a second cavity; e) Injecting a second plastic material into the second cavity so that a second portion is formed directly on the first portion of the injection-moulded part.

A device for die-casting metal material, including a screw unit for bringing the material into a thixotropic state and a cylinder/piston unit fed by the screw unit for applying pressure to the thixotropic material for the die casting, wherein a thermally controllable valve is arranged between the screw unit and the cylinder/piston unit.

A low pressure aluminum casting apparatus includes a pair of steel dies each presenting a molding surface and a heat transfer surface. Copper heat sink blocks are disposed on the heat transfer surfaces to remove heat from the steel dies. Steel contact plates and steel spacer plates can be disposed between the heat sink blocks and the steel dies to optimize cooling. In addition, a portion of each contact plate can be spaced from the steel die to reduce cooling. The steel dies include conventional cooling passages for conveying cooling fluid, and the heat sink blocks, contact plates, and spacer plates also include cooling channels for conveying cooling fluid.
