How aluminum alloy profiles are formed?

It is now the most urban rail trains, as well as the manufacturing methods and processes of large parts profiles used in the manufacture of CRH3 type emus.


According to the technical requirements of the components, the process is as follows: aluminum ingot - Dissolution alloy ratio - into rod material - extrusion forming - aging - surface treatment - cut by component size - finished product!
Extrusion; preheating; mold preheating; extrusion quality inspection (optical projection measurement); cutting; heat treatment; quality assurance tests; mechanical properties; cross sectional metallography; electrical conductivity) shipment..
