The scaffolding structure has boards (1) suspended on the lateral struts of the vertical frames, to bond them together. Extruded aluminum profile strips (2.1-2.5,3.1,3.2), forming the boards, are bonded together by welding across the longitudinal line of the scaffolding boards.MAIER PETER
13. A coupler for forming a chassis formed of a plurality of extruded aluminum beams having a central opening comprising: a central portion having outer walls, a pocket wall forming a single central pocket, and wherein each of the outer walls has an inner wall extending radially inward from ...
Thermoforming is suitable for forming parts that have high surface-to-thickness ratio and uses inexpensive molds made of wood, aluminum, steel, epoxy. Limitations are residual stresses, high levels of trim, non-uniform wall thickness and high energy costs. The latter are typically the first or ...
