One aspect relates to a device for producing a spacer having

a stem mold which has an inner space, wherein the inner space is accessible via a proximal opening and wherein the stem mold has a proximal wall which peripherally delimits the proximal opening of the stem mold,

a head mold which has in the interior thereof a hollow space, wherein the hollow space has a spherical surface-shaped inner surface and is accessible via a distal opening, wherein the head mold has a distal wall which peripherally delimits the distal opening of the head mold,

a metal core which has a stem part, a head part and a flange, wherein the flange projects out from the metal core, is arranged between the stem part and the head part and has a proximal surface and a distal surface,

wherein the stem mold and the stem part are shaped such that the stem part is arranged in the inner space, when the proximal wall is resting against the distal surface, and wherein the head mold and the head part are shaped such that the head part is arranged in the hollow space, when the distal wall is resting against the proximal surface.

Pet food bags, and methods of making the same, contain a seal that resists air exchange more than conventional bags thereby protecting nutritional ingredients that are susceptible to oxidation.

The present invention is directed to a packaging material free from aluminium in the form of a continuous foil or film, comprising a layer of microfibrillated cellulose (MFC), wherein the layer comprising MFC has been laminated or coated on at least one side with a heat-sealable material. The MFC layer contains at least 60% by weight of microfibrillated cellulose. The present invention is also directed to a method for induction sealing, wherein a packaging material to be heat-sealed by induction is placed against an induction heating surface.

A temperature control device is provided that is capable of making the temperature of a metallic mold speedily reach a target temperature. The temperature control device is provided with: a first medium circulating portion that circulates a medium via a first pipeline; a second medium circulating portion that circulates the medium via a second pipeline; a third medium circulating portion that circulates the medium via a third pipeline; a switching portion that switches the medium circulated through an object by selecting any one of the first pipeline, the second pipeline and the third pipeline; and a pressure supply portion that supplies a required pressure through a pressure pipe communicating with each of the first pipeline, the second pipeline and the third pipeline.

A manufacturing method of a plastic lens formed by using a metal mold having a fixed mold and a movable mold. The plastic lens comprises a flange part surrounding a lens face, and an image side face of the flange part comprises a black coating part and an outer peripheral part. The manufacturing method may include a molding process in which the plastic lens is molded by using the fixed mold for molding an object side lens face and the movable mold for molding an image side lens face and the flange part, a mold opening process in which the metal mold is opened by moving the movable mold, and a pushing-out process in which the outer peripheral part is pushed out by an ejector pin disposed in the movable mold when the mold opening process is performed or, after the mold opening process has been performed.

A system for thermoforming an object is provided. The system includes a mold and a pressure-box. The mold has a surface that defines a shape of the object and includes two or more portions of differing porosities. The pressure-box is operative to generate a pressure differential across the surface. The two or more portions apply the pressure differential at different loads, based at least in part on the differing porosities, to a material disposed onto the surface so as to form the object by deforming the material into the shape.

A method for fusing thermoplastic composite structures includes placing a thermoplastic substructure on an inner surface of a skin that is laid up on a shaping surface of a tool configured to maintain the shape of an outer mold line. The method further includes applying at least one metal layer over the substructure and applying an insulation layer over edge portions of the substructure and over exposed portions of the inner surface of the skin not in contact with the substructure and applying a vacuum bag that at least partly encloses the skin, the substructure, and the metal layer. The method yet still further includes applying heat to the shaping surface to fuse the substructure to the skin such that the skin exceeds its melting point and at least a portion of a raised segment of the substructure does not exceed its melting point.

A first resin member including a first contact surface and formed of laser beam-transmissive resin and a second resin member including a second contact surface, which contacts the first contact surface, and formed of laser beam-absorbing resin are arranged one upon the other. A laser welding apparatus includes a clamping unit abutting the second resin member and applying clamping force to the second resin member, a laser emitter emitting laser beam, a laser controller controlling output of the laser beam, a displacement sensor measuring displacement of the second contact surface in stacking direction of the resin members, and a control unit controlling the clamping unit to adjust the clamping force corresponding to displacement amount of the second contact surface continuously or intermittently obtained from the displacement sensor.
