The current inventive technology described methods and apparatus for the production of a helium-free balloon having customizable reflective features.

A method for producing a multilayer pipe with an outer layer which forms a pipe outer contour, an inner layer which forms a pipe inner contour, and at least one intermediate layer by means of a centrifugal casting process. A mixture of resin and microfibers is supplied to a rotating die in order to form the inner layer, and a specified separation of the resin and the microfibers is produced by controlling the die rotational speed during a specified time such that the content of the microfibers in a boundary layer, which starts from the pipe inner contour, is lower than the content in a stability layer facing the intermediate layer. The invention likewise relates to a corresponding multilayer pipe.

The method comprises of placing the palm side of a glove mold facing up, and raising the fingers portion of glove mold up, in such a way that the glove mold is tilting up at 15-45 in relative to horizontal position. The first pouring process is carried out by pouring silica gel liquid on the fingers portion of glove mold. Then adjust the glove mold to horizontal position, and rotate the glove mold by using its length as axis. Continue pouring silica gel liquid on the glove mold surface to carry out second pouring process. Let the silica gel liquid to be coated on the whole glove mold surface forming a semi-finished glove. Upon completion, let the glove mold to go through a dripping procedure for dripping treatment. After the dripping treatment, carry out vulcanization and cooling to obtain the corresponding silica gel glove.

A method of impregnating a fiber texture of hollow shape, the method including introducing a first suspension containing a first powder of solid particles of ceramic or carbon material into an inside volume defined by an inside face of a fiber texture of hollow shape placed in a mold, an outer face of the fiber texture being presented facing a wall of the mold; and using the action of centrifugal force to impregnate the fiber texture with the first suspension by causing the mold to rotate and varying the speed of rotation of the mold during the impregnation of the texture with the first suspension.

The invention is related to the production of pet preform and similar plastic products. as well as similar-shaped metallic pieces manufactured by plastic injection.

Systems and methods for improving adhesion of an insulating foam to a molded polymeric insulating structure through use of ozone gas for functionalization of molded polymeric surfaces of an internal cavity of the insulating structure.

A reinforced thermoplastic product may include a main body and a fabric reinforcing sheet that is disposed within a wall of the main body. The wall of the main body may be formed of or from a cast thermoplastic material and the fabric reinforcing sheet may extend circumferentially around the main body in order to reinforce the wall. The fabric reinforcing sheet may include a plurality of fiber bundles and a thermoplastic material that impregnates each fiber bundle.
