Modeling and development of the UG based CAD system for porthole extrusion dies of aluminum profiles;

Formation mechanism of “adsorbed particles”on surface of extruded aluminum profile and preventive measures;

The influence of extrusion speed and frictional status on Aluminum profile extrusion processes;

The developing history and present situation of China's aluminium profile;

Process control of alkaline etching for Aluminium profile;

The technological parameters of aluminium profile anode oxidation and sealing hole working procedure can influence the quality of anode oxidation film sealing hole,so we must pay attention to controlling the technological parameters while producing.

Numerical simulation of distribution of exit velocities of aluminum profiles extrusion;

Numerical simulation study of spring back in stretch bending process for aluminum profiles;

Factors and processing methods related during production of heat insulation break bridge of aluminum profiles are discussed in the paper.

Production practice of electric-deposition process for aluminium alloy profile;

Stretch-wrap bending of aluminium alloy profile has been extensively used in aircraft and automobileindustry.

After anodizing aluminium profiles,sealing reaction with the Ni-F systematic low-temperature sealing agent will go on continuously and slowly after sealing, i.

The extrusion finished product rate of aluminium profiles were effectively improved by technology measures,such as taking configurable ingot qualification system, adding die nitriding frenquency, adding high temperature felt etc and effective management measures.

In producing the bronze color electrophoretic coating aluminium profiles the differences of colors can be easily created.
