The extrusion installation is configured for manufacturing a complex profiled-element strip, such as a tread, based on elastomer compounds by co-extrusion, and comprises multiple extruders feeding elastomer compounds to an extrusion head. The extrusion head receives a proportion of elastomer compound of between 2 and 25% of the total volumetric throughput of the installation from at least one Archimedean-screw extruder and the rest from positive-displacement extruders.

An encapsulant compound apparatus, includes a mechanical operator, and an insert disposed on a surface of the mechanical operator. The insert operates to capture foreign material in the encapsulant compound.

A method and an extrusion device for producing a foamed body. A plastics melt is produced inside the casing of a first extruder. The plastics melt is conveyed to an outlet die of a second extruder. The conveyed plastics melt has a foaming agent and expands after being fed through the outlet die. Before the plastics melt is fed through the outlet die, variations in temperature between different radial positions over the cross-section of the plastics melt are reduced by an extruder screw device which has a number of screw spindles distributed around the periphery. The plastics melt which is thus thermally homogeneous is fed through the outlet die.

The present disclosure provides a container with an increased movable range of an upper wall with respect to a side wall. According to the present disclosure provided is a container including a side wall, an upper hinge member, and an upper wall, wherein the upper hinge member and the side wall are connected rotatably around a first rotation axis, the upper hinge member and the upper wall are connected rotatably around a second rotation axis, and the first and second rotation axes are parallel.

Provided is a resin panel without warpage, in which weight reduction and high rigidity of the resin panel have been promoted. The resin panel according to an aspect of the present invention is a resin panel having a back wall, a front wall facing the back wall with a gap therebetween, and ribs formed by having portions of the back wall depressed toward the front wall and welded to the inner surface of the front wall, characterized in that the back wall, the front wall and the ribs are configured by mold-clamping, in a split mold, a first molten resin in a molten state and incorporating a plate-shaped filler, which constitutes the back wall, and a second molten resin in a molten state and incorporating a plate-shaped filler, which constitutes the front wall, the first molten resin and the second molten resin having been extruded and flowed out from an extrusion apparatus, and the longitudinal direction of the ribs is non-parallel to the direction of flow of the first molten resin and the second molten resin.

The purpose of the present invention is to provide a molded article and a manufacturing method for a molded article by which it is possible to mitigate deformation of an opening. The present invention provides a molded article comprising a cylindrical base and an opening provided in the base, wherein a rib is provided adjacent to the opening. The present invention provides a manufacturing method for a molded article that includes a molded body formation step for forming a molded body having a cylindrical portion provided at one end thereof with an occlusion by molding a melted resin, and a cut-off step for cutting off the occlusion by cutting the cylindrical portion, wherein in the cut-off step, the cutting is performed in a state where a side wall of the cylindrical portion is warped in-plane by an external force.

A thermoplastic product, such as a film, tubing, sheeting, and a profile with a cross-section, is made by a process including extruding a melt-blended mixture comprising a thermoplastic polymer and a fluorocarbon additive through an extruding die. The thermoplastic polymer and the fluorocarbon additive are substantially homogenously distributed in the melt-blended mixture before extrusion. Upon cooling, the extruded product forms into a solid thermoplastic product comprising the thermoplastic polymer and the fluorocarbon additive and having a particular shape. The fluorocarbon additive has a lower surface energy than that of the thermoplastic polymer. As a result, a concentration of the fluorocarbon additive through a cross-section of the solid thermoplastic product is lower in the interior thereof and higher at the surfaces thereof. The solid thermoplastic product has a lubricity surface. The thermoplastic product having lubricity surfaces may be further flexible and/or elastic, or non flexible.

A hybrid extrusion press is provided with electric motors and hydraulic assist cylinders to cause a container holder to slide, wherein connecting rods are fastened to a container holder, the hydraulic assist cylinders have piston rods and gate devices connecting or disconnecting the connecting rods and the piston rods, and the gate devices are provided with hollow members fastened to the piston rods, enlarged diameter parts provided at single ends of the connecting rods and moving back and forth inside hollow parts of the hollow members, and locking parts provided at the hollow members and locking the enlarged diameter parts.

The present disclosure provides a container with an increased movable range of an upper wall with respect to a side wall. According to the present disclosure provided is a container including a side wall, an upper hinge member, and an upper wall, wherein the upper hinge member and the side wall are connected rotatably around a first rotation axis, the upper hinge member and the upper wall are connected rotatably around a second rotation axis, and the first and second rotation axes are parallel.

Methods and an apparatus are presented. A bulk molding compound is consolidated by sending the bulk molding compound through a die breaker and an extrusion die of a consolidation system.
