The classification of the names of aluminum alloy door and window profiles, to be honest, a layman only knows a little bit about it. For those old masters who have been engaged in the aluminum door and window industry for many years, most of the types of aluminum alloy door and window profiles or their products are also Just recognize as the commonly used ones. There are dozens of models and hundreds of profiles. Aluminum alloy doors and windows are the same, and there are even more styles and models. Most people learn about the general common sense, but they are vague for the names, styles, and profiles of doors and windows.

A sunroom, which is also known as a “garden conservatory”, “garden room”, “patio room”, “sun living room”, “sun porch”, and “winter garden,” is a building, either attached to or integrated into a major building, like a home or office, that allows for ample sunlight and landscaped views while sheltering from inclement weather.

1.The production of 6063 aluminum alloy material is controlled by chemical composition.

6063 aluminum alloy has become an important choice for the high-precision production of photovoltaic aluminum alloy profiles.

2.Smelting and refining process

It is melted in a rotary regenerative melting furnace at a melting temperature of 720-760℃. When the temperature is above 720℃, the refining agent is blown into high purity nitrogen and refined for 15 minutes. The amount of refining agent is 0.08% of the weight of the melt. After refining, the electromagnetic stirring is carried out for 15 minutes. Sampling and inspection strictly control the chemical composition of aluminum alloy solution, so that the material can achieve the required mechanical properties.

3.Foundry technology

The semi-continuously direct water-cooling casting method is adopted. Direct water cooling method has high cooling strength and fast cooling speed, which refines the casting structure, increases the density of the structure, and then improves the mechanical properties and heat treatment effect of the ingots.

4.Homogenization of cast rod structure

In order to reduce and eliminate the ingot segregation and improve the inhomogeneity of its chemical composition and structure, the aluminum alloy casting rod is homogenized. The technical condition of its control are to heat the casting rod to 540-550℃, keeping it warm for 8-10 hours, cool it with strong wind and cool it with water mist. After homogenizing annealing, cooling should be accelerated to ensure the uniformity of color after anodizing.

5.Process condition control of extrusion and aging

6063 aluminum alloy profiles extrusion, online quenching and aging process technical conditions, take control of the casting rod heating temperature within 440-480℃, mold heating temperature within 450-480℃, mold heating time less than 5 hours, extrusion cylinder heating temperature within 460-500℃, extrusion speed in 12-18 m/min, outlet temperature within 510-550℃. The cooling method is online air cooling or water mist cooling; controlling the temperature of extrusion profiles after online quenching aging treatment in 200±5℃, and holding time in 3 hours. The solid solution treatment of 6063 aluminum alloy combined with the extrusion process can avoid grain growth and improve the physical and mechanical properties of the profile products.

Door and windows is a whole. They are made of profiles, glass, hardware, strips and other materials that are combined through systematic and scientific design. They are functional products with wind pressure resistance, heat insulation, sound insulation and other properties. The material and structure of the aluminum profiles determine the firmness, thermal insulation, and wind pressure resistance of the entire window.

1. Characteristics of aluminum alloy door and windows
Corrosion resistance, good weather resistance, no harmful substances such as formaldehyde, excellent thermal insulation performance, in line with national energy conservation and environmental protection policies, and different color styles which can be achieved according to interior design and exterior wall design.
During the production process of door and windows, manufacturers will also use surface treatment such as anodizing, electrophoresis, powder coating, and wood grain to form an anti-oxidation and anti-corrosion protective film on aluminum alloys to extend the lifespan of aluminum alloy door and windows.

Solar panel frames and their supporting structure pillars, tie rods, support legs and so on are new products for aluminum alloy material application markets, which have been implemented and promoted globally. The following points briefly introducing the production technology and key nodes of the solar photovoltaic aluminum profile manufacturing process.
