An injection molding machine with an injection system and a clamping system. The injection system may include a removable injection module defining a portion of the material flow path. The injection module may include all of parts that come in contact with the material between the material source and the mold. The injection module may include a valve arrangement movable between a fill position to load the injection module with material and an inject position to eject material from the injection module into the mold. The actuators for the injection module may be supported on the machine rather than the injection module. The clamping system may include a platen linear actuator to open and close the mold, and a hydraulic clamping system to apply clamping force to the closed mold. The hydraulic clamping system may include a free-float valve manifold assembly that selectively places the hydraulic cylinders in free-float mode.

The disclosure relates to an injection nozzle (1) suitable for injection molding of thermoplastic materials, in particular polyolefin materials, the injection nozzle (1) comprising a housing (2) comprising a sleeve-shaped rear section (3) and a thereto coaxially arranged sleeve-shaped front section (4) surrounding a central passage (5) extending in an axial direction (z) forming part of a melt channel (6). In the central passage (5) a needle (7) is arranged movable in the axial direction (z) between a retracted open position and an extended closed position in which a gate (8) at a tip (9) of the front section (4) is closed by a front end (10) of the needle (7) in a sealing manner. A spacer (11) is arranged between the rear section (3) and the front section (4) defining a total length of the housing (2) in the axial direction (z).

Method for viewing and selecting production resources, in particular peripheral devices, for the injection molding industry, which are organized in at least one work cell for producing an injection-molded part and connected to one another via a network. Following a manual storage request on a control device, in particular a work cell controller, or on a production resource, in particular a processing machine, all connected production resources are queried and defined data, such as the respective settings, as well as program sequences, formulations and other configurations, are read out from these and, together with the internal settings, in particular those of the processing machine, combined to form a mold data record for this injection-molded part. A listing of production resources for the injection-molded part producible on this processing machine can be automatically generated from the mold data record and displayed at an output location, preferably of the processing machine.

The present disclosure pertains to injection molding methods, tooling, and products. An example injection molding tool that can be used to create both a part with an aperture and a part without an aperture. The injection molding tool has a first portion; a second portion; a first insert installed on the first portion, the insert comprising a protrusion that creates a gap relative to a sidewall of the second portion when the first portion and the second portion are closed to form an injection molding tool; and a material source that flows material into the injection molding tool, the material having a melt flow rate that is below a melt flow rate threshold to create a first part with an aperture due to the presence of the protrusion and the gap, wherein the aperture has no flashing.

In an injection molding system, bolt position related information recognizing unit which recognizes an attachment position of a bolt for each attachment is provided. Based on the attachment position of the bolt, or the attachment position of the bolt and a phase of the bolt stored in the bolt position storage unit, bolt attaching and detaching unit attaches and detaches the bolt to and from the attachment. Thus, even if the position of the bolt varies in accordance with the attachment, it is possible to attach and detach the bolt by recognizing the attachment position of the bolt.

The presented invention relates to a nozzle insert (100) for an injection moulding tool (300), wherein the nozzle insert (100) comprises: a supply line portion (101) extending in the nozzle insert (100), a multiplicity of nozzle tips (103), and a multiplicity of secondary channels (105), wherein respective secondary channels (105) of the multiplicity of secondary channels (105) are fluidically coupled to the supply line portion (101), wherein a respective secondary channel (105) of the multiplicity of secondary channels (105) is configured to discharge flowable compound, supplied through the supply line portion (101), from a respective nozzle tip (103) of the multiplicity of nozzle tips (103).

An injection molding machine includes: a mold clamping unit; an injection unit; and a safety cover that surrounds the mold clamping unit and the injection unit. The safety cover includes a detachable panel that is attached to an opening. The safety cover includes a door portion that moves between a position where the door portion blocks a second portion of the opening and a position where the door portion does not cover the opening. The safety cover has a size that is smaller than the opening but greater than the second portion. A detachable panel has a first stopper that restricts an opening motion of the door portion when only the second portion is open. The safety cover is provided with a second stopper that restricts the opening motion of the door portion when the opening is entirely open and the detachable panel is removed.

An injection molding unit for an injection molding machine for processing plastic including a carrier block and an exchangeable plasticizing cylinder which is removably receivable in a receiving bore, where a locking device is provided for locking and unlocking the plasticizer unit together with the carrier block by relative movement of bevel surfaces extending crosswise to the injection axis together with operatively connected locking elements which are guided on bearing surfaces, where a bearing nut is provided on the outer surface of the plasticizer cylinder, the surface of which bearing nut pointing in the direction of the carrier block forms at least one of the bearing surfaces, and a plurality of locking elements are provided which either have bevel surfaces pointing toward each other, independently of the carrier block and plasticizer cylinder, which slide on each other during a locking movement and during an unlocking movement, or have, on the side spaced apart from the bearing surface of the bearing nut, mutually inclined bevel surfaces which slide synchronously on bevel surfaces of the carrier block during a locking movement and during an unlocking movement.
