What Aluminum Parts Surface Treatment Methods Can We Provide?
Sandblasting is a very common performance treatment process. It uses high-speed jet abrasives to impact the surface of aluminum parts to remove oxide layers, burrs and impurities, while giving the surface of aluminum parts a uniform matte texture. We can strictly control the mesh number and spray pressure according to your needs to provide different touches from rough matte to delicate silk, and ensure a high degree of consistency in the surface texture of the same batch of products.
Anodizing Type II is the formation of a relatively dense artificial oxide film on the aluminum surface by electrochemical reaction. It can improve the corrosion resistance and insulation of the aluminum part. We can use this process to achieve rich color customization for you, and these parts also have unique metallic colors. In addition, for holes with precise tolerance requirements, we will perform masking in advance to prevent the film thickness from affecting the assembly.
Type III Hard Anodizing is low-temperature and high pressure anodizing to produce a thicker and harder oxide film. The appearance is usually dark gray or dark brown. This surface treatment can provide extremely high hardness and wear resistance to CNC aluminum parts, so they can be used in various extreme environments. However, due to the thickness of the film, the size of the part can change significantly, so we will reserve the thickness of the oxide film during the CNC machining stage to ensure that the oxidized finished product still meets the drawing tolerance.
This is a chemical immersion treatment process that forms an extremely thin chromate conversion coating on the aluminum surface. But unlike the film formed by anodization, the chromate conversion film is conductive. Therefore, this process is also very suitable for electronic aluminum parts, which can prevent corrosion without affecting the electromagnetic shielding performance. In addition, we can flexibly adjust the immersion time according to your needs, and provide a yellow or transparent color appearance, and ensure the uniformity of the film layer and minimize contact resistance.
The main principle of this process is to use static electricity to adsorb plastic powder on the surface of CNC aluminum parts, and bake it at high temperature to solidify it into a tough coating. This coating makes the parts extremely weather-resistant and UV-resistant. in addition. We can also make the surface of the parts smooth, frosted or orange-grained according to different needs.
These are purely physical machining methods, and they are also the surface treatment methods that many customers will choose to improve the appearance and texture of the product. Brushing creates a directional fine texture on the surface of a CNC aluminum part, while polishing grinds the surface of the aluminum part to a mirror-like effect. Of course, for polished parts, our factory will strictly control the surface roughness (Ra value) and coordinate with the subsequent oxidation treatment to ensure that the aluminum parts can maintain a lasting metallic luster.
How to Fabricate Aluminum Parts?
The reason why our CNC aluminum parts are so popular with so many customers is that our parts have excellent performance. These aluminum parts are now used in many industries. You may also want to know how our customized CNC aluminum parts are made. I will answer you below. It is mainly divided into five major parts. I will introduce it to you one by one below.
Step 1：Engineering & Programming
Our engineers will develop a solution based on your needs, then review the CAD model, evaluate manufacturability (DFM), and develop the most efficient fixture solution and tool path strategy. Then, they will use CAM software to write G code to simulate the processing path of the entire aluminum part. This is also to ensure that the risk of interference is avoided and the processing parameters are optimized before cutting begins.
Step 2：Material Preparation
We will choose the aluminum grade (6061,7075 or 6063) according to your requirements and check the material warranty. If you prefer , you can also choose it yourself. Then we will cut the aluminum rod or plate into blanks that are slightly larger than the final size, ready for further machining.
Step 3：CNC Machining
This step comes to the processing link, which is the so-called subtractive manufacturing. We can use a variety of CNC machining methods, such as CNC milling, CNC turning, etc., to remove excess material from the workpiece and gradually form the finished aluminum part. Moreover, our factory also supports 3-axis, 4-axis and 5-axis machining centers to ensure that your machining requirements can be met. That is, no matter how complex the structure is, or how simple the prototype is, DSR can do a good job.
Step 4：Secondary Ops
CNC machined aluminum parts will have some detail issues, so these parts require secondary processing. In terms of drilling, we can conduct precision drilling on the processed datum surface to process the internal threads that meet the requirements. For burr problems, we have to completely remove the sharp edges and burrs through manual trimming, vibration grinding or sandblasting to ensure that the parts feel smooth and will not hurt your hands during installation.
Step 5：Finishing & QC
Surface treatment and final quality inspection are the final and also very important steps. We carry out surface treatments such as anodizing and powder coating to meet your requirements to improve the corrosion resistance and aesthetics of CNC aluminum parts. Before shipping, we also use CMM and pass gauges to conduct a final review of key dimensions to ensure that all parts meet your standards.
Yes. CNC machining is the most efficient and now the mainstream process standard for cutting and forming aluminum. And CNC can also realize micron-level dimensional accuracy and high consistency of parts.
7075 aluminum alloy is stronger than 6061. 7075 contains a high percentage of zinc and has a tensile strength of up to 572 MPa.
According to the current international metal market conditions, the raw material spot price of pure aluminum ingots is usually US$2.20-$2.60/kg. And if you want to buy aluminum profiles for processing, the price will rise. Ordinary 6061 aluminum alloy rods are usually $5.00 – $9.00 USD/kg, while high-performance 7075 aviation aluminum is more expensive, usually $10.00 – $18.00 USD/kg or even higher.
From the unit price of raw materials, aluminum is indeed much more expensive than ordinary carbon steel, usually 3 to 5 times the price of steel by weight.
Firstly, because the machinability of aluminum material is good, the machining cycle is short, and the wear of aluminum on the tool is small, and it has good cost advantages. Secondly, the tolerance of CNC machining can easily reach ±0.01mm or even tighter. Third, after CNC machining, the aluminum parts can have a very smooth surface (Ra value). Finally, the process also supports mass production, which can also well maintain the consistency of aluminum parts.
Firstly, choose a suitable tool (such as a carbide end mill) and reasonably set the cutting parameters (rotation speed, feed rate and cutting depth) to prevent the tool from overheating or breaking during processing. Secondly, before processing, you also need to fix the aluminum plate on the workbench firmly to prevent it from vibrating and shifting during processing. After writing or importing the processing program, you can start the CNC engraving machine to cut automatically. During the whole processing process, you can use coolant or gas-assisted heat dissipation to improve the surface quality and tool life of the machine. After the processing is completed, the aluminum parts need to be cleaned and necessary surface treatment is required to obtain high-precision aluminum parts.
6061 aluminum alloy is a good choice for CNC machining. It has good mechanical properties, high strength and excellent machinability, is not easy to stick to the knife when cutting, and has a high surface finish.
CNC machine tools use programming control to process aluminum materials, so that the movement of machine tools can accurately and efficiently complete machining tasks such as cutting, milling, and drilling, and make parts of various shapes and sizes to realize high-precision, high-efficiency, automated production.
If you need to replace mechanical aluminum parts, then first of all you need to check the aluminum alloy properties such as strength, hardness, corrosion resistance, etc. to ensure that the aluminum meets the relevant requirements. Secondly, the dimensional accuracy and surface quality of the part should also be checked. Finally, you also need to consider whether the aluminum processing technology and structure are easy to install and maintain.
If you buy aluminum parts for car repair, you should pay attention to many things, such as price and quality.
