A molding method for making a monolithic component made of C-SMC and internally including a cavity, including preparing a press including first and second half molds and movable side carriages defining a molding space, and placing a core inside the molding space. The core comprises a membrane, delimiting a containing space shaped to form the cavity, and at least one connector engaged with the membrane. The method includes wrapping a charge of material to be molded around the core, fixing the core inside one between the first and the second half molds, and filling the containing space of the membrane with a filling material. After closing the half molds, applying a molding pressure and then emptying the containing space of the filling material and, after opening the half molds, removing the core from the molded monolithic component.

The present invention relates to a pouch forming apparatus comprising: a die, in which forming grooves are formed with a partition wall therebetween; and a punch member provided with a punch, which is configured to be inserted into each of the forming grooves to press the pouch film to form a pair of accommodation grooves in the pouch film, wherein the forming groove comprises a vertical space disposed above a forming groove bottom part connected to the partition wall and an inclined space connected to the vertical space and formed by providing an inner wall facing the partition wall, the inner wall defining an inclined surface .

A mandrel for a molding process that includes a first portion that has a first portion outer surface, a first portion inner surface, a first portion first end, and a first portion second end. A thickness of the first portion first end is greater than the first portion second end. A second portion has a second portion outer surface, a second portion inner surface, a second portion first end, and a second portion second end. A thickness of the second portion first end is smaller than the second portion second end. The first portion inner surface engages the second portion inner surface to form a mandrel that has a constant cross-section.

A device and a method for loading prefabricated parts into a molding tool of a press for the production of molded parts, in particular for the production of elastomer molded parts. For this purpose, the device comprises a plate-like carrier element with a top and a bottom intended for attachment on or to the press and a holding device for accommodating at least one interchangeable platen equipped with the parts. The holding unit is arranged on the supporting element at a clear distance from its bottom and the interchangeable platen comprises a plurality of passage openings to accommodate the parts. Furthermore, the device comprises a platen with pins which are arranged between the bottom of the supporting element and the holding unit, wherein the pins align with the passage openings.

The present invention provides a resin leakage prevention member 401 for use in a molding die 1000, wherein the molding die 1000 includes a lower die 200 and an upper die 100, the lower die 200 has a side member 201 and a bottom member 202, a space surrounded by the side member 201 and the bottom member 202 forms a cavity 204, the cavity 204 is configured to accommodate a resin material 20a, the side member 201 is configured to move relatively vertical to the bottom member 202, and the resin leakage prevention member 401 is disposed on a peripheral portion of an upper surface of the bottom member 202 and along an inner peripheral surface of the side member 201, thereby sealing a gap between the side member 201 and the bottom member 202 and preventing a resin from leaking from the cavity 204 into the gap.

A grip for a golf club includes a cylindrical portion into which a shaft is inserted; and an end cap portion. The cylindrical portion, on its outer surface, includes a minute projection region where a plurality of minute projections each of which has a maximum width of 0.2 mm or more and 1.2 mm or less are arranged at intervals of 0.05 mm or more and 0.7 mm or less. The minute projection region is disposed in a first region whose distance in an axial direction from a grip butt end is from 0 mm to 210 mm. Of the grip, a portion from the grip butt end up to 50 mm therefrom has a weight of 10 g or more, and the weight accounts for 39% or more of the whole weight of the grip.

Some embodiments of a compression mold for forming a rib-and-sheet part includes a mold cavity and a mold insert. A sheet is placed in the mold cavity, and the mold insert is placed on the sheet. A preform assemblage is placed in a gap that is formed between the mold insert and the wall of the mold cavity. A mold core is biased above the preform assemblage, prior to molding operations, via a compression spring.

Prior to curing a composite workpiece assembly, an expandable element can be inserted into a cavity of the workpiece assembly. The expandable element is configured to expand when a predetermined change is produced in an attribute of the element. The attribute can be a temperature of the element. The element is expanded by producing the predetermined change, and the workpiece assembly is cured while the expanded element is in the cavity, so that the expanded element applies positive pressure to inner surfaces of the cavity during curing. The expanded element can be removed from the cavity after curing. The expanded element can comprise a plurality of expandable pellets.
