Abstract:
Disclosed are an apparatus and method for molding an object. An object is compressed by an upper mold and a lower mold base part to form a top surface of a product, and the upper mold and the lower mold base part descend in a state where the object is compressed to form a lateral surface of the product through lateral surfaces of the upper mold and a lower mold.
Abstract:
An imprinting apparatus, for transferring a microstructure of a mold onto a forming material by pressing and mold-releasing, includes a plurality of driving devices which relatively move the mold the forming material to each other along an axis of a pressing direction, wherein the plurality of driving devices make different relative moving speeds of the mold and the forming material during the relative motion.
Abstract:
A mold separating device includes a base with a driven member and a driving member rotating on the base. The driven member has a first through hole in it, and the base has a second through hole in it. The through holes receive a first mold and a second mold. The first through hole is coaxial to the second through hole. A cavity is defined in an inner wall of the driven member. An ejector is elastically fixed in the cavity and can be expelled from the cavity. A separator is disposed on a front portion of the ejector. A rotatable shaft is fixed in the driving member.
Abstract:
An imprint lithography apparatus is disclosed that has a template holder configured to hold an imprint template and a substrate table, the template holder having a gas bearing configured to supply gas via a high pressure channel and to control a separation distance between the imprint template and a substrate held on the substrate table.
Abstract:
An apparatus (1) for the manufacture of plastic products, comprising a mold (2) in which at least one mold cavity (11) is provided in which terminates at least one runner channel (14B), wherein further a pressing device (18) is provided for operatively supplying into the runner channel an amount of at least partially plasticized plastic, and wherein between the pressing device (18) and the at least one mold cavity (11) at least one buffer chamber (13) is provided for buffering plasticized plastic (24) supplied from the pressing device (18) and in which at least one displacer member (21) is provided for pressing plasticized plastic (24) from the at least one buffer chamber (13) into the at least one mold cavity (11).
Abstract:
Compression molding apparatus for molding plastic closures for containers includes a rotary turret having a vertical axis and supporting circumferentially spaced and axially moveable opposing plungers each carrying a compression mold member. Each mold member is attached to its corresponding plunger by a quick change locking coupler including a cylinder with circumferentially spaced holes supporting balls for radial movement. Each mold member has an axially projecting stud with an enlarged head portion projecting into the cylinder, and a cup-shaped piston surrounds the cylinder and has a recess for receiving the balls in a released position. A spring urges the piston to a locked position with the balls engaging the stud, and a housing is recessed within the plunger to support the piston for axial movement against the spring to a released position in response to pressurized fluid received within the housing through a passage within the housing and plunger.
Abstract:
A plastics waste processor is provided for efficiently compacting and melting plastics waste, so as to form easily disposable compact plastic units having a volume considerably smaller than the unprocessed plastics waste. The plastics waste processor has a waste containment chamber, a rotating chamber door, a jam breaker bar to facilitate opening of the door when jammed by melted plastic waste, pneumatically driven waste compaction means with plastic shedding rams, a waste containment chamber heating system, a processor temperature monitoring means, a cooling means, and a control means. Further a cable and hose management system is provided for protection of moving cables and hoses, as well as a washdown system for automatic cleaning of the processor.
Abstract:
An apparatus for manufacturing products from material which is thermoplastically deformable, as from plastic, comprising:—a mold (2) with at least one mold cavity (3);—in the or each mold cavity (3) at least one slide (8);—movement means for moving each slide (8);—closing means for opening and closing the mold (2);—feed means for introducing, with the mold cavity (3) closed, said material in at least substantially plastic condition into the or each mold cavity; wherein the movement means (9) for moving the slide (3) are arranged for moving said slide forward at a relatively high speed relative to the movement speed of the mold parts upon opening and closing thereof, from a position at least partly retracted from the mold cavity, such that said material, as a result, is displaced in the mold cavity for obtaining the filling thereof, preferably at a speed high such that adiabatic heat development occurs in the or each mold cavity.
Abstract:
Composite acetabular components, and methods of making and using same, are described. The composites consist of a ceramic liner having a backing of plastic material, such as but not limited to ultra high molecular weight polyethylene (UHMWPE), molded around the ceramic liner. The back surface of the ceramic liner is textured to enhance the mechanical bonding strength of the plastic backing to the textured ceramic liner during the molding process.
Abstract:
A method for manufacturing a padded body composed of a skin layer formed in a bag shape and filler made of a granular or fragmental material padded into the skin layer comprising the steps of: mixing the filler and a water reactive binder; padding a mixture of the filler and the binder into the skin layer to form a padded body; and passing steam through the padded body. The binder reacts to the steam so that the filler adheres each other and adheres to an inner surface of the skin layer.
