If you don't understand the four major production

Specializing in high-grade color aluminum door profiles, aluminum alloy sliding door profiles, folding door profiles, swing door profiles, aluminum alloy sliding window profiles, swing window profiles, sunshine room profiles, etc

the production of aluminum door and window profiles goes through four processes: ingot preparation, extrusion molding, heat treatment and surface treatment. As a door and window person, these common sense can be

you need to know

I Casting preparation

the process includes the main processes of batching, smelting, casting, soaking and so on, forming ingots with certain chemical composition and overall dimensions

the prepared raw materials are melted in a gas or electric furnace. After melting, the melt passes through the static furnace, launder, flow plate and filter to the crystallizer, and then is cooled by water to form a certain shape of ingot

in order to ensure the smooth surface of ingots, multi-mode (multi crystallizer) casting is carried out by magnetic casting or hot top casting. Ingot soaking is to homogenize the metallographic structure in the casting state and dissolve the main strengthening phase

soaking is carried out in soaking pit. Soaking improves the plasticity of the ingot, which is conducive to improving the extrusion speed, prolonging the service life of the extrusion die, and improving the surface quality of the extruded profile

II Extrusion molding

extrusion molding is an automatic production line composed of ingot heating, extrusion, cooling, tension straightening, sawing and other processes

the equipment on the production line includes induction heating furnace, extruder, discharging platform, discharging conveyor, profile lifting and transferring device, cooling bed, tension straightener, storage platform, tractor, sawing machine, etc

the heating temperature of ingot is generally controlled at 400 ℃ ~520 ℃, and too high or too low temperature will directly affect extrusion molding. The extruder generally adopts a single acting oil press, with a tonnage of 1200 ~ 2500 tons

the diameter of the extrusion cylinder of the extruder changes with the tonnage of the extruder. The larger the tonnage of the extruder, the larger the diameter of the extrusion cylinder

the diameter of the extrusion cylinder is generally within the range of 150mm~300mm. The working temperature of the extrusion tool is 360 ℃ ~460 ℃, and the extrusion speed is 20 m/min~80m/min. Extrusion tools mainly include dies

extrusion dies are divided into flat die, split die, tongue die and shunt combined die according to structural characteristics. The production of aluminum alloy door and window profiles uses flat die and shunt combined die

the discharge table receives the profile extruded from the extruder and transfers the profile to the discharge table

the discharging workbench is mostly a horizontal bar transport model, and its horizontal bar movement speed is synchronized with the extrusion speed

the cooling bed is mostly of walking beam type, and a considerable number of fans are installed below to ensure the uniform cooling of the profile, so that the temperature of the profile is lower than 70 ℃ before straightening

the tension straightener is equipped with a torsion jaw, which can be tensioned and straightened while twisting and straightening. Behind the tension straightener is the storage table, which provides the profile to the sawing machine workbench, and the sawing machine cuts the profile according to the fixed length

III The aluminum magnesium silicon aluminum alloy used for heat treatment

aluminum door and window profiles is an aluminum alloy that can be strengthened. Through different quenching and aging systems, the profiles get their due mechanical properties. Aluminum door and window profiles are in RCS supply state, that is, the heat treatment is rapid cooling and artificial aging after high-temperature forming

IV Surface treatment

the surface treatment of aluminum door and window profiles mostly adopts anodic oxidation to make the profile surface silver white. Surface treatment can enhance the appearance of profiles and prolong the service life of aluminum door and window profiles

anodizing process: loading → degreasing → water washing → alkali etching → warm water washing → cold water washing → neutralization and light out → water washing → anodizing → cold water washing → warm water washing → hole sealing → drying → unloading → finished product inspection → the thickness of oxide film after anodizing of aluminum door and window profiles shall not be less than 10 μ m。

the surface treatment of aluminum door and window profiles can also be colored. Aluminum profiles requiring other colors can be obtained by natural oxidation coloring, electrolytic coloring and impregnation coloring
