Batch Production

Step 1: Selection of raw materials

Industrial aluminum profiles are industrial frame profiles obtained by heating aluminum rods and extruding molds, while aluminum rods are formed by melting and casting aluminum ingots, which are called raw materials for industrial aluminum profiles; and raw materials will directly affect the industry. Aluminum profile product performance.

Step 2: Aluminum Rod Heating

The heating treatment of aluminum rods must ensure temperature control. If the temperature is too high or too low, it will directly affect the hardness of the finished product, so the temperature must be strictly controlled during the heating and cooling process;

Step 3: Mold Design

The industrial aluminum profile is the final product of an aluminum rod extruded through the mold after heating, and the mold is a device with high-precision specifications designed according to the demand, which is used to extrude the profile product of the required specification and cross-section;

Step 4: Extrusion of industrial aluminum profiles

For extrusion production, extrusion temperature is a basic and critical process factor. The extrusion speed must be carefully controlled during the extrusion process.

Step 5: Straightening and correction of industrial aluminum profiles

The straightness of the aluminum profile affects whether the aluminum profile can be used on mechanical equipment, so the straightness of the aluminum profile is one of the important standards for the quality of the aluminum profile. Generally, the extruded profiles need to be straightened.

Step 6: Artificial Aging

The aluminum profiles produced by extrusion have low hardness before aging and cannot be used as finished products. Therefore, generally speaking, aging must be done to increase strength.

Step 7: Sandblasting

After the extrusion molding of industrial aluminum profiles, the surface will have obvious stretch marks, and the surface micropores are relatively large and relatively rough, so they must be sandblasted.

Step 8: Cutting

The length of the aluminum profile is generally 6.01 meters, and the precise cutting of the aluminum profile is required according to the drawing. Our general cutting error is ≦0.5mm. In addition to cutting to length, diagonal and bevel cuts in aluminum profiles are also possible.

Step 9: Drilling and tapping

Generally, when aluminum profiles are internally connected, drilling and tapping are required. The drills used for drilling and tapping aluminum profiles of different specifications are different. Therefore, drilling and tapping are also one of the aspects to test the processing strength of an aluminum profile.

Step 10: Aluminum Profile Fixing

After cutting, drilling and tapping, it is necessary to use aluminum profile connectors to connect the aluminum profiles. As long as the installer installs according to the drawings, he can make the desired aluminum profile frame, equipment cover, assembly line workbench, etc.

Step 11: Surface Oxidation Treatment

Generally, the surface of aluminum profiles is treated with anodized silver white, which is elegant, beautiful and corrosion-resistant. Generally, after this step is done, the finished aluminum profile will come out after cooling.

Step 12: Packaging

Because the quality requirements of industrial aluminum profile products are very high, and the overall aesthetics of the appearance are very particular, the requirements for later packaging are very strict.

Quality Control

Aluminum profile CNC processing is a precise aluminum profile processing method, which can process aluminum profiles with high precision and stable quality. In the process of CNC machining of aluminum profiles, quality control is very important. Some common quality control methods include:

QC

Quality Control

Check whether there are scratches, oxidation and other problems on the surface of the aluminum profile;

Check whether the size of the aluminum profile meets the requirements;

Check whether the hardness of the aluminum profile meets the requirements;

Check whether the appearance of the aluminum profile meets the requirements.

CNC processing of aluminum parts belongs to relatively high-precision processing. During the CNC process of aluminum parts, the quality is ensured according to the following steps:

1. Guarantee the accuracy of CNC machine tools. CNC machine tools are the carrier of CNC machining of aluminum parts. Ensuring the accuracy of CNC machine tools is an important basis.

2. The choice of tool, the tool is the top priority of CNC processing, a good tool can get twice the result with half the effort. Aluminum CNC-processing high-speed steel knives and special aluminum alloy knives are ideal choices.

3. When processing aluminum parts, the tool speed should be high-speed, a high-feed processing method, and the margin should be less. Because the aluminum alloy is relatively soft compared to steel, it is easy to stick to the knife when the speed is low, and it will also reduce the processing efficiency. If it is finishing machining, it is necessary to ensure the smoothness of the aluminum parts, and that the feed can be appropriately reduced.

4. Selection of cutting fluid. Although cutting fluid is only an auxiliary material in the CNC processing of aluminum parts, the selection of cutting fluid is also very important. Semi-synthetic cutting fluid should be used for the CNC machining of aluminum profiles, which is helpful for smooth chip removal.

5. Reduce the amount of deformation after cutting. This problem is often encountered in the CNC processing of aluminum parts. The accuracy is very high when the size is measured just after processing, but a slight deformation occurs after a while. Although it is not visible to the naked eye, it can be found that the dimensional tolerance has become larger with a measurement tool. This situation is a kind of stress deformation. In order to reduce stress deformation, we need to reduce vibration during processing and add a process of eliminating internal stress after rough machining before finishing. This can alleviate the situation of processing deformation.
