A mould (1) and accessories thereof for the forming of an orthopaedic spacer made of medical cement, defining a moulding cavity (2) delimited by a moulding surface (3) configured to impart a pre-established shape to the medical cement and to create the orthopaedic spacer, wherein at least one sector (6) of the forming mould (1) defining at least one portion of the moulding surface (3) is made with a thermoplastic copolymer based material.

Provided are a production method of a mold, a manufacturing method of a pattern sheet, a production method of an electroform, a production method of a mold using an electroform, and an original. The production method includes: preparing an original having an inclined portion which is formed in an enclosed shape on an outer peripheral portion of a protruding pattern formed at a center portion on a base and gradually increases in thickness from inside toward outside, and a thermoplastic resin sheet; and forming a recessed pattern on the thermoplastic resin sheet by pressing the original which is heated against the thermoplastic resin sheet at a position where a flat surface of the original and a surface of the thermoplastic resin sheet are separated from each other, cooling the original in the state where the original is pressed, and separating the original from the thermoplastic resin sheet.

A method and apparatus for shaping, compacting, and supporting a composite material (C) contained between two flexible membranes (G, F) and capable of being stretched over a porous mold (A) are described. The apparatus enables the use of inexpensive mold despite the high pressures used. A counter-mold (M) having the same characteristics as the mold can be used in certain instances. The equipment enables the use of a plurality of molds and counter-molds during one manufacturing cycle.

A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.

Disclosed is an elastomeric bladder tool and related systems and methods. In one embodiment, the elastomeric bladder tool comprises an elastomeric inner layer substantially defining an inner cavity of the elastomeric bladder tool, an elastomeric outer layer substantially defining an outer surface of the elastomeric bladder tool, and a permeable middle layer positioned between the elastomeric inner layer and the elastomeric outer layer. The permeable middle layer has greater permeability than both the elastomeric outer layer and the elastomeric inner layer to allow for evacuating of gases that have entered the permeable middle layer.

An iridescent vehicle badge (and methods for making it) that includes a translucent, polymeric badge having a non-planar shape and comprising an interior and an exterior surface. Further, at least one of the surfaces of the badge comprises a plurality of diffraction gratings that are integral with the badge, each having a thickness from 250 nm to 1000 nm and a varying period from 50 nm to 5 microns. In some cases, the thickness can range from 500 nm to 750 nm. The period, in some cases, can vary within a set of discrete values in one or more portions of the at least one of the surfaces of the badge, e.g., from 150 nm to 400 nm.

This disclosure concerns a master model for the production of a mold, comprising: (a) a first part, a second part comprising a textured surface; wherein the first part and the second part are connected.

The manufacturing method of the sheet having the needle-like protruding portions includes: preparing a mold including needle-like recessed portions, and a solution supply device including a slit-like opening formed at a nozzle distal end portion; supplying a solution from the solution supply device to the mold in a state that the nozzle distal end portion is pressed to a front surface of the mold, and filling the solution in the needle-like recessed portions; and moving the solution supply device relatively to the mold in a state that the nozzle distal end portion is brought into contact with the front surface of the mold, and, as a hardness distribution in a thickness direction of the mold, an average value of a Young's modulus at a part within 40 μm from the front surface of the mold is 1.9 MPa or higher and 100 MPa or lower.
