A writing utensil adapted for promoting the development of a tripod writing grip includes an elongate body having a substantially polygonal cross section, and having three faces extending between a proximal end and a distal end thereof, and a boss member extending from an intermediate portion of the elongate body, the boss member being adapted for impeding a user's fingers from sliding along a longitudinal axis of the elongate body.

A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.

A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.

A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.

Provided is a double injection molding system capable of continuously and automatically manufacturing four molded products for a vehicle at a time, the double injection molding system including: a first molding device which molds the openable plates of the molded products for a vehicle through injection of plastic; a second molding device which receives the openable plates and molds the sealing portions through injection of rubber around the openable plates to finish the molded products; and a transport device which takes out the openable plates formed by the molding device and transports the openable plates, to the second molding device, so that the double injection molding process of the openable plates and the sealing portions is automated to secure product reliability and to improve productivity.

A method of forming an orthodontic aligner from an aligner digital model, the method comprising the steps of: three-dimensionally printing an intermediate structure comprising fused filaments from a biocompatible thermoplastic according to the aligner digital model via fused deposition modelling; coating the intermediate structure with a biocompatible translucent photopolymer; and irradiating the coating with ultraviolet light to cure the coating on the intermediate structure, thereby forming the orthodontic aligner.

An apparatus for simultaneously manufacturing a plurality of plastic molds comprises: an injection molding tool comprising a first and second molding tool halves and —a gripper tool comprising a plurality of gripper members to which suction can be applied. The first and second molding tool halves are movable into the closed position and into an open position. A front surface of the first molding members comprises recesses to allow the formation of pins projecting from the rear surface the plastic mold into the recesses to make the plastic molds adhere to the first molding members. The gripper tool is movably arranged only in a direction parallel to the first surface into the space formed between the first and second surfaces for transferring the plastic molds to the gripper members and out of this space again.

The disclosure is directed to an injection molding device (1) comprising an injection molding machine and an injection mold (2) arranged therein. At least one first and at least one second outer mold half (3, 4) are arranged in a movable manner relative to each other in a first direction (x). A central part (5) that is arranged there between and comprise s a lower part (6) an upper part (7) which are arranged rotatable about a rotational axis (8). The lower part (6) and the upper part (7) are separated from each other by a bearing arrangement (9) arranged between the upper part (7) and the lower part (6).

A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.

A method of in tool formation and assembly of an active grille shutter system, followed by an automated testing process. The method includes providing a tool having a plurality of sliders that assist in the formation and assembly of the active grille shutter system. The components of the active grille shutter system are individually formed in a single tool, with each of the components being spaced apart from each other. After formation of the components a number of sliders and an end of arm tool push the components together to form the assembled active grille shutter system. The end of arm tool then takes the assembled active grille shutter system to a testing station where the operation is checked.
