How to use anodizing to ensure the flatness of the product?

Friends who make machines should often encounter some long thin wall parts, how to process this product? First of all, the process we think of is nothing more than repeatedly to open rough finishing, or do some plastic adjustment, to do the aging of heat treatment, these are the first consideration. Without these processes, the product would look like a bow.

Recently, we have implemented a new process to ensure the flatness of the product, although there are certain conditions, but effective. That's anodizing.

What? Anodizing? Yes, you heard me right. This process measure may not be suitable for all products, but some long products are very practical. We can do a lot on an aluminum plate, front and back processing, and then do some connection structure with the main aluminum plate in some built-in structure, and then do anodizing, and then remove this connection point.

Many people will ask: "Do anodizing, some places are not exposed to the white?" Yes, but for most products

The important thing is the appearance, there is definitely a face in use is not visible, is built in. For this kind of function, we can communicate with the customer and strive for the customer's consent that we have a small point to do some anode blanking.

Why can anodizing ensure the flatness of the product? There are two reasons for our analysis.

The first is that anodizing has a certain hardness after the film, and the force of this hardness plays a certain role in the flatness.

The second is anodizing, which has a process of high temperature baking and chemical soaking, which has a certain effect on the aging of the material.

Perhaps these two points of analysis may not be particularly accurate, but we have been verified by many practical operations, basically the flatness of the product after anodizing can be guaranteed within 0.1 or 0.05. In this way, we reduce the repeated finishing and to do some plastic adjustment process.
