MANUFACTURING METHOD AND INJECTION MOLDING SYSTEM
A method including a first step of performing clamping of a mold, injection and dwelling in an injection molding machine, a second step of performing a conveyance and a cooling of the mold outside of the machine, and a third step of performing a conveyance of the mold into the machine, an opening of the mold and an ejection of a molded part in the machine. The second step is performed for a first mold, the third step and the next first step are performed for a second mold. The first mold is conveyed by a first conveyance apparatus which is arranged on one lateral side of the machine. The second mold is conveyed by a second conveyance apparatus which is arranged on the other lateral side and is independently driven from the first conveyance apparatus.

INFLATION NEEDLE, ITS MOLD AND METHOD OF MANUFACTURING SAME
An inflation needle, its mold and method of manufacturing same are provided. The inflation needle (10) includes a hollow cylindrical probe (12); a hollow conic base (14) disposed at one end of the hollow cylindrical probe (12); a hollow externally threaded member (16) projected out of the hollow conic base (14), the hollow externally threaded member (16) being distal the hollow cylindrical probe (12) and communicating therewith; and a plurality of handles (18) disposed on an outer surface of the hollow conic base (14).
MOULD FOR INJECTION MOULDING MADE BY ADDITIVE MANUFACTURING
A mould for injection moulding is provided which has a mould body having a plurality of boundary surfaces, the plurality of boundary surfaces having at least one moulding surface configured to delimit a mould cavity. The mould body is made by additive manufacturing. The mould body has a functional domain portion on which the plurality of boundary surfaces and the moulding surface are formed, the functional domain portion being composed of a solid, continuous material structure covering a fraction of the mould body, and an application domain portion which is the complement of the functional domain portion in the mould body, the application domain portion being composed of a three-dimensional material lattice structure having an ordered repetition of unit cells including a periodic minimal surface. The at least one geometrical parameter of the periodic minimal surface is tuned locally to form unit cells with different densities of material.
Injection-moulded component, joint, injection-moulding device, and method for producing an injection-moulded component
An injection-molded component having a casing body of plastics material and a core which is made of a core material, in particular of a metal, which is at least partially received within the casing body and is at least partially insert-molded. The injection-molded component may in particular serve as a joint part of a joint. As a result of the preferably metallic core, the injection-molded component, despite comparatively small dimensioning, is capable of being comparatively highly stressed. By virtue of the casing body of plastics material, a minor actuation noise may be implemented for the joint, even without complex lubrication.

Polarizable compact
A polarizable compact is provided with high productivity, which makes a polarizing sheet resistant to the occurrence of color unevenness and voids and also resistant to the occurrence of variations in polarization degree accompanying thermal shrinkage and the like of a protective layer (protective film). A polarizable compact is used for glasses, and a method of manufacturing the same. An injection-molded portion made of a transparent plastic material is thermally bonded to the concave surface side of a polarizing sheet having a predetermined curvature radius. The polarizing sheet has a polarizer layer held between first and second protective layers respectively serving as a convex surface side and a concave surface side. Both the first and second protective layers are formed from transparent films by a casting method with retardation (Re)≤50 nm. The transparent films for the first and second protective layers are respectively formed from an acylcellulose-based film and a polyamide-based film.
