Flexible molds have an elastic membrane supported by modules, arranged next to one another along a horizontal longitudinal axis of the mold. Each module has traction units, each forming a respective group with a respective thrust unit, with the groups arranged opposite one another at a preset distance. Pairs of traction units are arranged opposite one another in a direction perpendicular to the axis, and the respective thrust units thereof are arranged therebetween. The modules hold the membrane with the mold via reinforced eyelets distributed on both edges parallel to the axis. Each traction unit has linear actuators arranged horizontally and another linear actuator arranged vertically, which together enable movement. The membrane is previously deformed according to an approximation of the prior design of a part to be molded, and prestressed according to a mathematical prediction of the deformation thereof after receiving a conglomerate in liquid or plastic state.

The invention is an intensive use furniture item made by a two step molding process using heat zone control in the mold to dispense different plastic charges into the mold while controlling zones of the mold with heat being applied and thermal insulators separating mold zones for molding the bed or part of plastics differing in characteristics such as color, durability, surface finish and chemical resistance.

A multi-part acrylic cold curing composition for metallography moulds to produce a metallography mount is described. The composition has a storage stable solid part and a storage stable liquid part. The parts are operable to form a mixture which polymerises to a solid mass upon mixing of the parts together. The solid part comprises polymer powder and initiator and the liquid part comprises acrylic monomer and optionally activator or accelerator. The initiator is present in an amount effective to polymerize the acrylic monomer component upon being mixed with the liquid part. The composition comprises a cyclic ester side group containing monofunctional acrylic monomer. The composition liquid part may contain a mixture of monofunctional monomer(s) and polyfunctional monomer(s), wherein the polyfunctional monomers comprise between 12 and 22% w/w of the total monomers in the uncured composition. Metallography mounts and processes for producing the mounts are also described.

An apparatus and a method for forming a leveled surface of at least one pasty mass in a mold are described. Thereby, the mold is particularly adapted to mold lipstick mines, wherein the mold was filled with the pasty mass and the pasty mass was at least partially cooled in the mold. The apparatus comprises a means for at least partially melting the surface of the at least one cooled pasty mass in the mold to level the surface by heat introduction, wherein the heat introduction takes place via focused optical photo emission.

A composite material molding method is provided for forming a composite material. The molding includes disposing a reinforcing base material in a cavity inside an openable and closable mold, injecting resin into the cavity in a state in which a clamping pressure is exerted on the mold and curing the resin. When injecting the resin into the cavity, the injection pressure of the resin is adjusted between a first pressure that is higher than the clamping pressure and a second pressure that is lower than the clamping pressure, and the injection pressure of the resin is lowered from the pressure that is higher than the clamping pressure to the pressure that is lower than the clamping pressure at least once. The resin is thereby injected such that the pressure inside the cavity does not exceed the clamping pressure from the start of injection to the end of injection of the resin.
