Everything Else
The production process of aluminum profiles for casement windows is mostly the same as for all other aluminum profiles. Aluminum profiles for casement windows go through four processes: ingot casting, extrusion, heat treatment, and surface treatment. The specific production process is as follows:
1. First of all, the raw materials, aluminum ingots and other metal elements melted together, and then casting, homogenization. After this process, the aluminum matte produced is usually round.
2. Then the extrusion process takes place, in which the aluminum ingot passes through a die with a certain temperature. Afterwards, a specific shape of aluminum profile is formed. Cooling, straightening and cutting are then carried out.
3. Then aging treatment will be carried out, different aging treatment will affect the mechanical properties of aluminum profiles. Generally, we will determine the aging treatment according to the specific use of the aluminum profile. Or we will carry out the corresponding operation according to the customer’s demand.
4. After the aluminum profiles are formed they need to be surface treated. We offer a variety of surface treatment, the most common are anodized, powder coated wood grain transfer and sandblasting. After different surface treatment can present different colors, textures and styles of aluminium casement window sections. It can also extend the service life of aluminum window profiles.
