injection molding is a process used to fabri e products commonly plastics in mass production. it is most suited to produce large quantities of the same item, such as automobile elements, mechanical gears, toys and plastic storage containers. this article will delve further into the injection mol
aluminum extrusions are shaped pieces of aluminum that are manufactured in long strips. if you cut pieces of extruded aluminum to the same length immediately after it's extruded, the cross-sectional profile should be exactly the same for each piece. extrusion is especially compatible with aluminum's
