This disclosure relates to ethylene interpolymer compositions. Specifically, ethylene interpolymer products having: a Dilution Index (Y.sub.d) greater than 0; total catalytic metal 3.0 ppm; 0.03 terminal vinyl unsaturations per 100 carbon atoms, and; optionally a Dimensionless Modulus (X.sub.d) greater than 0. The disclosed ethylene interpolymer products have a melt index from about 0.3 to about 500 dg/minute, a density from about 0.869 to about 0.975 g/cm.sup.3, a polydispersity (M.sub.w/M.sub.n) from about 2 to about 25 and a CDBI.sub.50 from about 20% to about 97%. Further, the ethylene interpolymer products are a blend of at least two ethylene interpolymers; where one ethylene interpolymer is produced with a single-site catalyst formulation and at least one ethylene interpolymer is produced with a heterogeneous catalyst formulation.

In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.

The invention relates to a system for producing three-dimensional models. The system preferably includes a z-axis drive unit on a side of a build container that is coupled to a build platform for moving the build platform in a vertical direction.

At a temperature at the time of molding, an end surface of an ejector pin in a sliding direction is as high as or higher than an upper surface of an upper surface portion of a mold body, the upper surface being adjacent to a cavity on the ejector pin side.

The invention relates to a method for creating a surface structure on a mold, wherein first structural elements are created using a laser structuring process in a first step, and second structural elements, which are smaller than the first structural elements, are created using an anodic oxidation process in another step following the laser structuring process. The invention further relates to a mold of said type and finally to a plastic film or a plastic component having a surface structure as well as to a method for the production thereof.

The present invention relates to a device for manufacturing a mould element for moulding a tread by injection of pressurized aluminium, characterized in that it includes a die and a steel counterform, said die and said counterform forming a chamber, and in that the die has slots into which strips are inserted, said slots being wider than the thickness of the strip to enable the strips to come out of the slots when demoulding the mould element from the chamber, and in that the insertion depth of the slots is equal to or less than 25 mm. The chosen width of the slot is a compromise between the hold of the strip during injection of the pressurized aluminium and the ease of demoulding said strip. The slots are blind in order to limit the penetration of the strips, which only project from one side and do not pass through the die.

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.

In one example, a method includes positioning a tool in a mold, forming a parison of melted plastic, closing the mold around the parison and tool such that part of the tool is positioned between a portion of the mold and the parison, creating a blow molded structure by inflating the parison so that the melted plastic comes into contact with an interior portion of the mold and into contact with the tool, and after the mold is closed, operating the tool to form an integral compression molded element within the mold, and a parting line formed by the mold in the blow molded structure forms no part of the integral compression molded element.
