A composite foamed container forming, in the body portion 23, thereof, a foamed region in which foamed cells 1 are distributed, the foamed region including a first gradationally foamed region A having a gradational distribution of the foamed cells of which the length L in the direction of maximum stretch gradationally decreasing from the outer surface side of the body portion 23 toward the inner surface side thereof and a second gradationally foamed region B having a gradational distribution of the foamed cells of which the length L in the direction of maximum stretch gradationally decreasing from the inner surface side of the body portion 23 toward the outer surface side thereof. The container has a large resistance against the pressure exerted on the outer surface, good liquid-dispelling property and, at the same time, has improved appearance and heat resistance.

A moving apparatus is disclosed that may be for moving a tool of an injection molding machine. It may comprise a beam having at least a part that extends generally longitudinally in a first direction. The beam may be configured such that the tool can be moved relative to the beam in said first direction. The apparatus may also comprise an actuator for moving the at least a part of the beam in a second direction. Also disclosed is a method of moving a tool. The method may comprise: (a) moving a tool along a beam that generally extends in a first direction; and (b) moving at least a part of the beam in a second direction. The first directions may be orthogonal to second directions.

The invention relates to a method for producing a strip (12) of rubber, including non-continuous reinforcements, said production method including at least one step that involves cutting the reinforcements of a strip (12) of rubber including reinforcements that can be cut and that move in a conveying direction (DC). According to the invention, the production method is characterised in that each reinforcement is cut by heating the reinforcement locally and remotely using a laser beam (18). The invention also relates to a device (14) for cutting the reinforcement of a strip (12) of rubber, the cutting device (14) including a head (16) for cutting the reinforcements and a conveying device (17) for moving the strip in a conveying direction (DC) and past the cutting head (16), the device (14) for cutting the reinforcements being characterised in that the cutting head (16) includes an emission source (19) that emits at least one laser beam (18) for heating each reinforcement of the strip locally and remotely in order to cut same.

The present invention relates to a thermoplastic cast which is easy to reuse or implant, and to a production method for same. The cast according to the present invention comprises: a core material (10) to which is attached polycaprolactone while being made in a mesh shape by the mutual crossing over and connecting of threads having a predetermined diameter, with the weaving of a plurality of strands of thin threads; and a structure (20) which is made using a polycaprolactone composite and is formed so as to surround the outer part of the core material (10) by means of insert injection. With the present invention, the patient experiences no discomfort despite the invention being structurally robust, because ventilation properties are improved due to the cast being formed in a mesh shape and because the structure, which is made using the polycaprolactone composite, is formed so as to surround the outer part of the core material by means of insert injection.

In accordance with a first aspect of the invention, the exterior trim part for a vehicle comprises a fibrous porous structural layer. The exterior trim part further comprises at least one at least sectional perforated film layer, which is made of thermoplastic polyurethane with a melting temperature according to DSC of at least 140°C. The film layer is materially connected to the fibrous porous structural layer, at least in sections.

Disclosed is a method for producing a porous polymer film. This method includes the steps of: (I) irradiating a polymer film with an ion beam of accelerated ions so as to form a polymer film that has collided with the ions in the beam; and (II) chemically etching the polymer film formed in the step (I) so as to form openings and/or through holes corresponding to tracks of the colliding ions left in the polymer film. In the step (I), the polymer film is placed in an atmosphere with a pressure of 100 Pa or more, and the polymer film placed in the atmosphere is irradiated with the ion beam that has passed through a beam line maintained at a lower pressure than the pressure of the atmosphere and through a pressure barrier sheet disposed at an end of the beam line to separate the beam line from the atmosphere.

A stretch blow molding system (200) is provided. The stretch blow molding system comprises a cylinder (201) including a movable stretch rod (202) and a blow-mold valve (204). The blow-mold valve (204) comprises a first fluid port (204a) in fluid communication with a first pressurized fluid source (364a). The blow-mold valve (204) also includes a second fluid port (204b) in fluid communication with a second pressurized fluid source (364b). A third fluid port (204c) of the blow-mold valve is in fluid communication with the cylinder (201) and selectively in fluid communication with the first fluid port (204a) and the second fluid port (204b).
