A cutting insert has a substantially triangular or square basic shape with a top surface and a base surface that are connected together by lateral flanks. A cutting edge is formed at the transition between at least one flank and the top surface. The cutting edge extends between cutting corners, and the cutting edge has a portion that is convex in side view of a flank. The convex portion of the cutting edge is bounded on both sides by concavely curved portions.

A mould (10) for a tire, comprising two shells (30) that are each intended to mould a lateral sidewall of the tire, a ring of sectors (20) intended to mould a tread of the tire, each sector (20) of the ring of sectors comprising a radially inner face (21) having a moulding lining (22). The mould (10) has microstructures (50) that are designed to fill a clearance between two moulding linings (22) of adjacent sectors (20) and/or between a moulding lining (22) of one sector (20) and a shell (30), when the mould is closed.

A multi-cavity baking cup pan comprised of a contiguous metal skeleton frame that defines a metal frame perimeter around the entire top area of each individual baking cup and comprised of baking cups made of a silicone material that adjoin the metal frame perimeter surrounding each baking cup.

Method for manufacturing three-dimensional articles with a flexible wall, by means of a mould (1-2) and a counter-mould (3) between which pieces (4) are arranged that will form the article to be obtained. Between the pieces (4), the mould (1-2) and counter-mould (3) a conduit network (7) and cavities (6) are delimited into which, through first points (8), a plastic material is injected in a melted condition, whereas through one or more second points (9) said conduit network is connected to a vacuum network.

A device for producing an edging of a flat extended panel has: a molding tool; a material dispenser which is movable in relation to the molding tool, for dispensing a material for the edging, wherein the molding tool has: a first mold body having a holding region for the panel; a second mold body having a holding region for the panel such that the panel is capable of being held by the first mold body and by the second mold body; a third mold body which with the first mold body shares a common contact region, wherein the first mold body, the second mold body, and the third mold body are configured such that they conjointly with the panel surround a space in which the edging is configurable; an access duct to the space, the former being configured between the second mold body and the third mold body.

A mold that: makes it possible to manufacture a molded foam body wherein a reinforcing member extends to a portion of an outer face of the molded body main body that corresponds to a parting line in the inner face of the cavity of the mold; and prevents molding problems stemming from the reinforcing member getting into the aforementioned parting line. Also: a method for manufacturing a molded foam body using the aforementioned mold; and a molded foam body manufactured thereby. A recessed step portion (6) that faces the cavity (4) of the aforementioned mold (1) is provided in the mating face (3a) of at least one part (3) of said mold (1), at at least a portion of the parting line (P) (formed in the inner face of the cavity (4)) adjacent to which the reinforcing member (22) is disposed. Said recessed step portion (6) is designed such that if the reinforcing member (22) gets in between the mating faces (2a, 3a) at the parting line (P) when the mold is fastened, said reinforcing member (22) can escape into the recessed step portion (6).

A multifunctional mandrel end cap for the fabrication of composite parts having an end cap core operatively connected to a mandrel and substantially sealed using a bonding agent or end cap sheath. The end cap sheath substantially encloses the end cap core and seals engage perimeter sealing features of the end cap core. The end cap core has a passageway fluidly connecting the mandrel with a vacuum source. The vacuum source is engageable by a vacuum conduit having one or more vacuum conduit perimeter sealing features.

A mold used in the production of plastic materials includes a fixed element and a moving element forming a mold cavity in the closed position of the mold, at least one of the elements including at least a sealing system of the mold cavity, the sealing system being provided with at least one deformable surface made from elastic material in order to produce a sealing contact with a closure surface of the mold cavity, and the deformable surface being mounted to slide in a wall of the mold in such a way as to adjust the sealing contact.

A method for production of molded parts, in particular parts consisting of a fiber composite material, is illustrated and described. In order to reduce the load on the membrane, the membrane according to the invention can be slipped past the seal and the membrane can at least in part be slipped past the seal as a result of the expansion force.
