Extrusion
Aluminum
SunHui aluminum extrusion is designed for high volume projects.We can customized any profile as design needs,fast production for extrusion tools.Before machining to have a accurate profile raw material is the best way to reduce unit cost and prodution time.
What is Extrusion?
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section.Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work with brittle materials, because the material encounters only compressive and shear stresses.It also creates an excellent surface finish and gives considerable freedom of form in the design process.
Drawing is a similar process, using the tensile strength of the material to pull it through the die.
It limits the amount of change that can be performed in one step, so it is limited to simpler shapes, and multiple stages are usually needed. Drawing is the main way to produce wire. Metal bars and tubes are also often drawn.
Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). It can be done with hot or cold material.
Commonly extruded materials include metals, polymers, ceramics, concrete, modeling clay, and foodstuffs. Products of extrusion are generally called extrudates.
Also referred to as “hole flanging”, hollow cavities within extruded material cannot be produced using a simple flat extrusion die because there would be no way to support the center barrier of the die.
Instead, the die assumes the shape of a block with depth, beginning first with a shape profile that supports the center section.
The die shape then internally changes along its length into the final shape, with the suspended center pieces supported from the back of the die. The material flows around the supports and fuses to create the desired closed shape.
The extrusion of metals can also increase their strength.

Surface finishing for extrusion parts
Painting
The process is sprayed with liquid paint. The appearance looks more beautiful after spraying various colors. At the same time, the life and service life of the product can be extended due to an extra layer of protection.
Powder Coating
Powder coating is a strong, wear-resistant finish that is compatible with all metal materials.
Anodizing
Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface.
Elextroplating
Electroplating can be functional, decorative or corrosion-related. Many industries use the process, in which chrome-plating of steel automobile parts is common.
