An undercut processing mechanism includes: a molding core for forming an undercut portion; an inclined pin slidable in a first direction inclined relative to a die opening direction of a molding die during the removal of a molded product from the die; and a guide rail for guiding the movement of the inclined pin. The inclined pin has a slide block movable in contact with the guide rail. The guide rail is so formed as to contact the slide block over the entire stroke of the inclined pin so that the first direction of movement of the inclined pin may be regulated, and is also so formed as to have a shape of a high bending rigidity in a particular direction of the slide block.

Provided is a method and device for batched compression molding of rubber and plastic products by means of multiple mold cavities, including alternating operation of a blank shuttle and a male mold that is in a bottle cap mold, being controlled by means of engagement of two partial gear sets. Mold opening motion, isostatic pressing energy storage, and spring energy storage are implemented by means of the engagement characteristic of the partial gear sets, and mold closing and compression molding are implemented by means of the non-engagement characteristic, isostatic pressing energy storage, and pressurization of the partial gear sets. The method and device effectively resolve the general problem of low production efficiency and poor precision and stability of existing compression molding cap manufacturing equipment.

Disclosed is a press-molding apparatus for a cosmetic patch, suitable for use in cutting a piece of patch fabric to a predetermined shape while being pressed using a press, including: a planar pressing plate, which forms a pressing portion of the press; at least one cutter, which is fixedly secured to the lower surface of the pressing plate and protrudes therefrom so as to cut the piece of patch fabric through pressing of the press, and is formed in a cylindrical shape so that a plurality of stacked pieces of patch fabric is simultaneously cut and the cut pieces of patch fabric are received in the space inside the cutter; and an ejector, which separates the pieces of patch fabric received in the cutter from the cutter.

A mould for the production of slabs in granular material and/or grits and/or sands with curing resins comprising a flat bottom, a perimeter framework operatively or rigidly connected to the flat bottom wherein the perimeter framework comprises a plurality of side walls, the flat bottom and the perimeter framework delimiting a compartment for forming the slab; a plant for the production and a method of forming slabs in granular material and/or grits and/or sands with curing resins are also provided.

A molding apparatus for injection molding or compression molding includes an “A” portion of a mold, a “B” portion of the mold, and at least one core plunger/ejector. The core plunger/ejector provides dual functionality, wherein it participates in molding operations by consolidating a feed material in the mold cavity, and also is responsible for separating the part from various mold surfaces and ejecting it from the mold.

Methods and apparatuses are provided for manufacturing a transaction card. The disclosed methods and apparatuses may be used to form a transaction card frame within a mold. The transaction card frame may include one or more recessed portions formed within a first surface of the transaction card frame. The one or more recessed portions may be configured for affixing one or more electronic components.

A component of a slip assembly is formed by rolling sheet molding compound into a rolled charge. The rolled charge is positioned in a compression molding press and compressed to produce a molded element. The molded element is removed from the compression molding press and can be machined for use as the component of the slip assembly. The component can be a slip segment or can be a cylindrical body for the slip segment. The compound layers in the molded component can be oriented in a number of different orientations in the component and can increase the overall strength of the component.
