Lu: xingcai belongs to common processing products, for its production process you have to know? Made ample preparations in this regard, even its oxidation problem also has the corresponding processing method.

Aluminum production process

1, casting

Smelting good liquid aluminum under the condition of the corresponding casting process, casting by deep well system, cooling casting into all kinds of round bar.

2, squeezing

According to the profile section of product design and produce mould first, using extrusion machine heating good round casting rod extrusion forming of the mould.

During the extrusion with a air cooling quenching process and its after artificial aging process, to complete the strengthening heat treatment.

3, coloring, and oxidation

Aluminum profile extrusion good, its surface corrosion resistance is not strong, must through the anodic oxidation surface treatment to increase the corrosion resistance and wear resistance of aluminum and aesthetic appearance.

Aluminum oxide

1, hot water washing

Hot water washing purpose is aging membrane layer, optimum temperature 40 ~ 50 ℃, time of 0.5 ~ 1 min.

2, dry

Drying is good with natural air, the hot water filling keep workpiece hang on the shelf, let work on the surface of the free water in downflow Chui straight direction.

3, aging

According to climate condition to decide, there are in the summer the sun exposure in the sun, rainy or winter available oven to bake.

4, unqualified parts repair

Unqualified conductive oxide film piece should be pick out before drying, aging process, avoid to affect the roughness of the workpiece surface.

Above is the oxidation and matters needing attention about the process of aluminum processing analysis, hope can help to you.
