A hybrid molded body according to this embodiment is a hybrid molded body in which a prepreg made of a fiber reinforced plastic and a resin are integrally molded, and the resin includes a covering part that covers at least a part of the prepreg in the boundary part of the prepreg and the resin.

A hot runner device includes a first block and a second block. A supply nozzle is connected to the first block. A nozzle unit is connected to the second block. The first block and the second block are connected to each other so as to be slidable relative to each other along the longitudinal direction of a hot runner block. First and second positioning pins are inserted into first and second insertion holes of the second block. The first insertion hole is larger than the second insertion hole.

A molding system and a method for operation of the molding system are provided. The method includes flowing a molten polymeric material from an upstream device into an in-mold tuning chamber in a filling position where the in-mold tuning chamber is positioned at least partially within a mold cavity. The method also includes adjusting at least one of a temperature of and a pressure applied to the molten polymeric material in the in-mold tuning chamber to create a first tuned molten polymeric material and releasing the tuned molten polymeric material into the mold cavity from the in-mold tuning chamber.

A mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided. The venting cavity, which is in air-conducting connection with the blind-hole end of the filament cavity, has a depth between 1 μm and 20 μm. A method of manufacturing the mold insert includes providing first and second insert plates, forming a portion of a filament cavity into at least one of the front faces of the insert plates, forming a venting cavity into the front face with the filament cavity, and bringing the front faces of the plates into close abutment to form a filament cavity.

A molded article formed from a blend, the blend comprising: from 1 wt. % to 30 wt. % of a polypropylene; and from 60 wt. % to 99 wt. % of an ionomer formed from a partially neutralized precursor acid copolymer, wherein the precursor acid copolymer (a) comprises copolymerized units of ethylene and 5 wt. % to 30 wt. %, based on the total weight of the precursor acid copolymer, of copolymerized units of an ?,?-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms, and (b) has a melt index, I2, (according to ASTM D1238 at 190 C, 2.16 kg) of 10 g/10 min to 4,000 g/10 min, and wherein about 25% to about 65% of the acid groups derived from the ?,?-ethylenically unsaturated carboxylic acid of the precursor acid copolymer are neutralized.

A resin part includes a molded main body that has a plate shape with a longitudinal direction and is constituted of an injection-molded product. The resin part has a gate portion that is a vestige of a resin injection gate. The gate portion is located in an end face part of the molded main body to cross a position corresponding to a center of gravity of the molded main body; the end face part extends in the longitudinal direction of the molded main body.
