Mold fitted with an interchangeable counter stretch molding rod
Disclosed is a mold for manufacturing a container from a preform, the mold including: a side wall, a mold bottom having a through-passage in the center thereof, a cylinder including a body and a counter stretch molding rod that is mounted so as to be slidable relative to the body between an extended position in which the counter stretch molding rod projects relative to the mold bottom and a retracted position, a stand on which the mold bottom is mounted, this stand including a lower stage, an upper stage and a spacer detachably inserted between the upper stage and the lower stage and defining the cavity in part.

Mold for blow molding, method for manufacturing resin container using same, and resin container
A blow molding mold in which a holding mechanism is independently provided to a bottom mold and is configured to be capable of gripping a protruding portion provided to a bottom portion of a preform independently of a gate portion, and a rotation mechanism is configured to be capable of rotating the bottom mold, relative to a neck portion of the preform which is in a stationary state held by neck molds, in a state where the protruding portion is gripped by the holding mechanism.

METHOD AND APPARATUS FOR PRODUCING DOUBLE-WALLED CONTAINERS
A method and apparatus for the formation of double-walled containers with the structure of two integrally connected and adjacent containers extending in the same direction with an air gap between them, stretch-blow moulded as single bodies out of thermoplastic material, and suitable for mass-production. A thermoplastic tubular blank is formed and then heat-conditioned. The heat-conditioned tubular blank is then mechanically stretched longitudinally and blow-formed outwards by gas pressure to conformingly and stretchingly assume the tubular blank to the shape of a first dual-container shaped mould cavity set in order to form a stretch-blow moulded first container integrally connected to a second container, with both containers extending in opposite directions. Next, additional heat-conditioning is applied to further heat-condition as necessary the stretch-blow moulded second container and if deemed an advantage, at least part of the first container. Then at least one profiled inversion piston and a second dual-container shaped mould cavity set are provided along with one or more wall stability devices applied to at least part of the wall surface(s) of either or both of the two integrally connected stretch-blow moulded containers, such that the second container side wall(s) may be inverted at least partially inside-out, while at the same time the second container bottom wall at least substantially does not invert, in order for the second container to become a substantially mirror-image inverted second container extending in the same direction as the first container, and an air gap is formed between the first container and second container.
CONTAINER PRODUCTION METHOD
A container production method including a preform setup step of disposing a preform in a blow molding mold and engaging a filling nozzle with a mouth of the preform; a blow molding step of liquid blow molding the preform by supplying a pressurized liquid into the preform; a liquid discharge step of releasing the blow molding mold and pressing a trunk of the container after molding with a pressing portion that is inserted from a clearance between separated mold pieces adjacent to each other to discharge a liquid in the container to the outside of the container by a predetermined amount; and a headspace forming step of forming a headspace in the container by separating the filling nozzle from a mouth of the container.
CONTAINER PRODUCTION METHOD BY LIQUID BLOW MOLDING
A container production method by liquid blow molding. The method includes a head space forming step of forming a head space in the upper portion of a container, in which, with the container disposed in a cavity, a bottom panel portion molded into an upward convex shape on a bottom of the container is inverted by pushing it down with a pushing rod and is plastically deformed into a downward convex shape.
Methods for making a balloon catheter and for producing an inventory of balloon catheters
Making a balloon catheter includes increasing a temperature of material forming an elongate body positioned within a cavity in an adjustable molding iris, and increasing a fluid pressure within a lumen extending through the elongate body. A segment of the elongate body is plastically deformed in response to the increased fluid pressure, and limited in outward expansion via contacting movable blade members forming the adjustable molding iris.
Machine component facilitating mold base movement
A blow molding machine assembly configured to be mounted to a blow molding machine to move a mold base configured to form a container base. The blow molding machine assembly includes an over-stroke cylinder and a counter-stretch rod. The over-stroke cylinder is configured to move the mold base between an extended base position and a retracted base position. The counter-stretch rod is movable between a retracted rod position in which the counter-stretch rod does not extend out from within the mold base, and an extended rod position in which the counter-stretch rod extends out from within the mold base.
