This chapter covers the semi-permanent press tooling: dummy blocks, stems, containers, container liners, and their repair, maintenance, and lubrication. Fixed Dummy Blocks Most aluminum extrusion presses are now fitted with fixed dummy blocks. They offer several advantages over loose dummy blocks: Operator involvement is virtually eliminated.

Item Type: extruded aluminum tubeThe dummy block attached with the stem shears an aluminum ring from the container during each return stroke, and this has to be removed from the stem (Ref 3). Indirect Extrusion In indirect extrusion, the die at the front end of the hollow stem moves relative to the container, but there is no relative displacement between
In extrusion, a preheated cylindrical aluminum billet is pressed through a steel die with a pressing ram . At the end of each extrusion cycle, the pressing ram, the so-called dummy block, must separate instantly and cleanly from the billet without pulling the extruded section from the die, as this will cause blisters in the profile.
Wellste is your reliable aluminum extrusion manufacturer and supplier in China. Wellste aluminum extrusions is the process of forming aluminum profiles. Firstly according to the design, the mold is designed and manufactured. And then the heated aluminum billet is extruded from the mold by the extruder in an aluminum extrusion plant.

T-Slot Aluminum Extrusion. T-slot aluminum extrusion is a structural fabricated die that utilizes an engineered cross-sectional profile that is both strong and versatile. Aluminum extrusion in itself is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses.
A process and apparatus for extruding aluminum into products, wherein aluminum logs are first heated to a predetermined temperature in a furnace, then are cut into billets of predetermined lengths, and then the billets, while still hot, are extruded into predetermined products in an extruder. In the process, the logs are cut into billets with a cross cut circular saw immediately

May 31, 2012 Direct Chill (DC) casting is a vertical semi- Continuous casting process used for fabrication cylindrical billets or rectangular ingots/blooms from non-ferrous metals such as Aluminum alloys, Copper alloys, Magnesium alloys. The Direct Chill (DC) cast ingots are further processed by either Extrusion, Rolling or Forging technologies.
Alu-ject Controller. At the end of each extrusion cycle, the dummy block must separate cleanly from the butt, without removing the section from the die, and without breaking the mandrel cone in the dummy block. Aluminum sticking can be a serious problem, especially when using the softer alloys, and with larger billets.
