Industrial automation devices and fixtures or supports are the most common aluminum items used. Using a CNC lathe to turn aluminum alloy provides the advantages of aesthetics, low weight, ease of forming, and moderate hardness. As a result, CNC services are more popular with clients. We inquire whether they need anodizing since the anode oxidation procedure has more than one step, which means the pricing is radically different.
Why Aluminum Materials Require Anodizing
Let’s take a look at why metal has to be anodized:
1. Improves corrosion resistance
Because of its high activity and the ease with which it may form alumina chemical reactions with oxygen and air, aluminum is a corrosion-resistant metal. To view the alumina film, you’ll need a magnifying glass or a microscope. The alumina matrix is protected from oxidation by a thin layer of alumina film, making it resistant to corrosion.
2. Improves wearability
Unlike steel, aluminum materials are prone to scuffs and scratches but may harden with time. There is a hardness of up to 300HV on the anodized industrial aluminum profile’s surface, making it resistant to scratching and wear.
3. Improves Insulation
Although aluminum conducts electricity well, it still has to be correctly insulated. Insulation requires anode oxidation treatment because the aluminum anode coating is not electrically conductive.
Aluminum items’ exteriors are often painted to give them a more appealing appearance. Anodized aluminum has intense pores and a wide range of colors before it is sealed, making it an excellent surface for dyes and metal salts.
Characteristics Of SLA 3D Printing
One of the many methods of fabricating things in the modern world is SLA (Stereolithography). A Vat photopolymerization process is involved. As a result, it has been referred to as resin 3D printing automation, which comprises SLA, DLP, and LCD 3D printing. Although they all employ a light source to cure photopolymer incentives, there are significant distinctions between the three automation.
- Selective curing of polymer resin is achieved using a UV laser.
- An ultraviolet (UV) light source is used in DLP to cure the resin layer.
- LCDs distinct patterns via the usage of an LCD module.
SLA 3D projector provides a variety of features, including:
In SLA machines, curling is one of the most common problems that need to be addressed. As a result of light exposure during the curing process, the resin shrinks rarely. Curling occurs when the material shrinks significantly, causing massive internal tensions between the newly formed layers and the previously cemented material.
2. Layer adhesion
The UV laser pass, which is required to cure the liquid resin in SLA printed objects partially, has isotropic mechanical characteristics. As a result of the subsequent laser passes, the previously cemented layers merge to a much greater extent. After the printing process is complete, the fixing process begins.
