INTRODUCTION OF PRODUCTS AND TECHNOLOGY
 
►Cold forging is a manufacturing process involving the shaping of metal using localized compressive

force  with no or less cutting. It’s a kind of process wherein the cold metal flows plastically by volume

re-distributing or transferring under compressive forces into a variety shapes within the dies to obtain

desired parts or blanks.

It relies on the die to control the metal flow and forms parts by metal massive volume transferring. The frequently-used extrusion methods are: forward extrusion, backward extrusion, combined extrusion and ironing process. It is a kind of advanced production technology of high-precision, high efficiency, environmentally friendly and low power consumption, often used for large-scale production of small and medium-sized forgings.
 
►Anodizing (anodic oxidation), the electrochemical oxidation of the metal or alloy. Parts of the metal

or alloy as the anode, the use of electrolysis to the surface oxide film is formed. Metal oxide thin film

changes  the surface state and properties, such as surface color, improve corrosion resistance,

improved wear

resistance and hardness, protect the metal surfaces. Such as aluminum, anodized aluminum and its

alloys

in the appropriate electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode,

in certain conditions, and under the action of applied current for electrolysis. Anodic oxidation of

aluminum or an alloy thereof, aluminum oxide thin layer formed on the surface, having a thickness

of 5 to 20 microns, hard anodic oxide film of up to 60 to 200 microns. 
The so-called aluminum anodic oxide is an electrolytic oxidation process, in the process, the surface

of aluminum and aluminum oxide film is usually converted to, this layer of a protective oxide film, as

well as some other decorative features. From this definition anodized aluminum, only this part of the

anodized film generating process
