Scaffolding element (100) with insulation, said scaffolding element (100) comprising a frame (110) of metal braces (111) and a set of fastening means (120), arranged to fasten the scaffolding element (100) to a supporting structure (20) of a scaffolding structure (10). The invention is characterised in that the scaffolding element (100) furthermore comprises a block (130) of insulating material, and in that the block (130) is cast around the frame (110), so that the frame (110) is completely covered by said insulating material but so that the fastening means (120) are not covered by said insulating material. The invention also relates to a manufacturing method and a kit of parts.

Methods for branding foam articles are provided. The methods include forming molded foam articles from polylactic acid, heating a surface, and pressing the surface against the molded foam article to produce a brand. Branding PLA-based molded foam articles advantageously produces a brand having high contrast and high resolution compared to other foam material.

A flexible-die forming apparatus includes a piston, a coil, an upper die, a magnetorheological elastomer, and a lower die having a cavity formed thereon. The upper die is arranged to be overlappedly rested on top of the lower die. The piston is movably received in the receiving cavity of the upper die. The magnetorheological elastomer is mounted at a lower portion of the piston, and is received in the receiving cavity of the upper die. The coil is provided and wounded on an exterior surface of the upper die and the lower die.

Uniform hardenability is achieved in plastic injection mold and die block tooling of 20 inches and larger by the use of 0.05-0.20 vanadium in conjunction with low carbon steel in which ingots are hot worked to form mold and die blocks having cross sections of 20 inches and larger followed by water quenching and tempering.

An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.

A method for forming a tool for creating a formed component includes providing a forming tool having a core and cavity with respective core and cavity shutoff bands. Core and cavity finished parting planes are determined, wherein the engagement of the core and cavity finished parting planes defines a forming cavity. Rough portions of the core and cavity shutoff bands are removed to define respective rough parting planes. The respective rough parting planes are offset by approximately 130 microns from the respective core and cavity finished parting planes. The core and cavity are semi-finished to relieve stress within the core and cavity. The core and cavity shutoff bands are fine cut so that outer surfaces of the core and cavity shutoff bands are equal to the respective finished parting planes. The engagement between the core and cavity outer surfaces is substantially free of gaps.

This invention pertains to plastic injection mold tooling, and also large forgings, formed from a low carbon mold steel having markedly increased hardening and hardenability properties in large sections as contrasted to currently available commercial products. The above attributes are obtained together with equal or better machinability and improved mold parting line wear. When manufactured in conjunction with a double melt process, this invention can improve significantly polishing characteristics and other attributes of molded parts in tooling sets.

A method for sealing a fastener employs a mold which provided with an inlet port for molding material. The mold is then positioned over a fastener and the mold is sealed against a structure. A moisture cured polyurethane reactive adhesive (MCRPA) as a molding material is then heated and injected into the mold. Upon solidification of the MCRPA, the mold is then removed to expose the MCRPA to atmospheric moisture and cured to leave an in-situ molded cap formed over the fastener and sealed to the structure.
