Indirect Extrusion - an overview ScienceDirect TopicsIndirect extrusion, also called backward/reverse extrusion, as shown in Figure 2 (b), is characterized by no friction between the billet and container wall. Thus, the indirect extrusion has many technical advantages as follows:1. A great decrease of extrusion load compared with direct extrusion, thus for a certain extrusion equipment, smaller cross sections can be extruded under lower billet

Research Status of Steel - Aluminum Joining Technology Self-piercing riveting is essentially a cold connection technology, its unique way to connect it can effectively overcome the aluminum alloy, magnesium alloy, titanium and other light metal materials difficult to use resistance spot welding welding shortcomings, not only for the same material between Double-layer and multi-layer connection of

Stamping Press and Metal Forming Glossary & Terms AIDA

Die. 1. A tool used on a press for any operation or series of operations, such as forming, drawing, piercing and cutting. The upper member (or members) are attached to the slide (or slides) of the press, with the lower member clamped or bolted to the bed or bolster, shaped so that the material placed between them is cut or formed when the press makes a stroke. The Basics of the Plastic Injection Moldmaking ProcessPlastic injection mold making is a tremendously useful process in the manufacturing sector. No matter what industry you pick, they will invariably use a plastic mold

Topology optimization of stamping die components using

Today, die design standards are used to design the structure of die components. These standards are usually based on high safety factors. So, the die components are often heavier and larger than required. In this article, a software package is developed which can design an appropriate topology of body structure of stamping die components with a reduced weight. Toxophilite - The Archery HandbookJan 31, 2013 · Toxophilite - The Archery Handbook. Toxophilus, from the greek Toxoi (bow) and Philia (love).
