A method for manufacturing a microprojection unit (10) according to the invention involves: a microprojection tool forming step of forming a microprojection tool (1) by bringing a projecting mold part (11) into contact from one surface (2D) side of a base sheet (2A) including a thermoplastic resin, and thus forming a protrusion (3) that protrudes from another surface (2U) side, and withdrawing the projecting mold part (11) from the interior of the protrusion (3); a joining step of joining the one surface (2D) side of the base sheet (2A), in which the microprojection tool (1) has been formed, and a tip end of a base component (4); and a cutting step of cutting the base sheet (2A), to which the base component (4) has been joined, along a contour (4L) of the base component (4) at a position more inward than the base component's contour (4L) in a planar view of the base sheet (2A) as viewed from the microprojection tool (1) side, to manufacture a microprojection unit (10).

A system for constructing a composite structure includes a braiding machine, a winding tool and a forming machine. The composite structure is constructed of a wound tubular braiding. The wound tubular braiding is constructed of a biaxial or triaxial tubular braid of unidirectional tape.

A tool for a thermoforming process to form a moulded product from wet pulp fibre material includes two or more moulds each having a moulding surface, an actuator assembly, and a fluid extraction system. At least one of the moulds is displaceable by the actuator assembly between first and second positions and has fluid extraction paths extending through the mould to transport fluid away from the moulding surface. One of the moulds has a first layer that is substantially rigid to form a support member and is in communication with a heating subsystem of the fluid extraction system, and a second layer that is, in use of the tool, between the first layer and the wet pulp fibre material. The second layer is formed of a material that has interconnected internal voids forming part of the fluid extraction paths and has a lower heat transfer coefficient than the first layer.

Disclosed is a rigid and monolithic composite under-vehicle protector containing phenolic felt and a polyurethane material applied by spraying on the phenolic felt. A production method for the under vehicle protector is also disclosed.

Disclosed is a mold for partially shortening the circumference of a tube billet and a using method of the mold. The mold comprises an upper mold, a lower mold and a mold core used for being inserted into a tube cavity of the tube billet, wherein the upper mold is provided with an upper mold cavity, the lower mold is provided with a lower mold cavity, and the upper mold cavity and the lower mold cavity are matched to form a mold cavity. After the mold core is placed in the mold cavity, a tube billet deformation cavity is formed in the mold cavity; and the upper mold cavity and/or the lower mold cavity are/is in the shape of a flaring, the two sides of the flaring are arc-shaped, and included angles are formed between the two sides of the flaring and the moving direction of a movable mold.

A method of forming a polymeric foam material is provided and includes providing a precursor material having a first thickness, the precursor material being an open-cell foam material and applying a uniaxial compressive force to the precursor material to compress the precursor material to a second thickness, the compressive force causing a cell structure of the precursor material to collapse. The method also includes heating the precursor material at a molding temperature for a first time period while the compressive force is applied, the first time period being sufficient to heat the precursor material to a softening temperature, removing the compressive force from the precursor material, and maintaining the cell structure of the precursor material in a collapsed state.

Method for production of articles and semi-finished products made of cellulose acetate, comprising the steps of recover-mg waste material consisting of cellulose acetate derived from previously made cellulose acetate articles and/or semi-finished products, distributing or positioning a mixture of at least one polymeric material inside a mould, heating and pressing the mixture inside the mould in order to form the articles or semi-finished products. The mixture is formed at least partially by the waste material consisting of cellulose acetate and the articles and/or semi-finished products may be subjected to a cooling and pressing step. The mixture is formed at least partially by fragments of cellulose acetate.

A workstation for a film-processing packaging machine defines a film transport plane in which the packaging film can be transported. In addition, the workstation comprises an electrically operable heating assembly. The latter in turn comprises an electrically conductive planar resistance heating element which in a plane parallel to the film transport plane has dimensions that are greater by a factor of at least 5, preferably at least 10, than in a direction perpendicular to the film transport plane. The resistance heating element is arranged between a heating plate and a clamping plate. The disclosure also relates to a packaging machine with such a workstation and to a method for operating such a workstation.

A method of curing spokes (10) is provided in which first molds of a first (14) and second series (16) of molds are placed into a platen, and force and heat applied. The platen (12) is opened and the first mold (1(1)) of the first series (14) is moved relative to the platen while the position of the first mold (1(2)) of the second series (16) is kept the same relative to the platen. Force and heat are applied to the molds. The platen (12) is opened, and the first mold (1(1)) of the first series is removed while the second mold (2(1)) of the first series is kept within the platen. A cured spoke is removed from the first mold of the first series.
