In che modo il produttore di estrusione di alluminio esegue il processo di estrusione?

Cos'è l'estrusione di alluminio?

Per il produttore di estrusione di alluminio, l' estrusione è un processo per la realizzazione di profili con una sezione trasversale fissa. Il materiale viene spinto o tirato attraverso uno stampo con una sezione trasversale. In questa pagina vorremmo coprire tutti gli argomenti relativi all'estrusione dell'alluminio, dalla progettazione CAD 3D alle tecnologie speciali.

In che modo il produttore di estrusione di alluminio esegue il processo di estrusione?

La tecnologia di estrusione per profili in alluminio si compone dei seguenti punti:

1. Pressing equipment is being prepared for work;
2. Technological tools - press washers, matrix holders, dies, washers, support rings, knives for removing pressure residues - are prepared for work;
3. The pressing tool is heated in stone resistance furnaces;
4. The aluminum ingots are loaded into a gas furnace and heated;
5. The profile is pressed;
6. With the help of a stretching machine, the profile is straightened;
7. The profile is cut to length;
8. The cut profiles are placed in a basket and sent to the aging oven.

Aluminum extrusion manufacturer carries aging process. It is a process of heat treatment of a finished profile. Moreover, it consists of heating and maintaining the profile at a high temperature, followed by cooling in air.

Why Aluminum extrusion?

The extrusion method allows you to end up with finished products with high strength rates. Similarly, it gives you confidence that your property will be reliably protected. The extrusion technology not only gives aluminum high strength, but also allows the profile to be reinforced with stiffening ribs. Due to which the protective roller shutters show such high results when tested for impact resistance.

The extrusion of a metal profile is the process of forcing or pulling an alloy through forming holes (matrix) under high hydraulic pressure. An aluminum extrusion manufacturer carries it in order to obtain a profile with a given cross-section.

The technological process of extrusion is carried out in extruders - devices for continuous processing of raw materials. The extruder for forming metal for the production of a profile consists of a:

• body with heating elements
• a screw that feeds the material into the extruder
• a temperature control system

 Depending on the number of screws, extruders are subdivided into:

• One
• Two
• three-screw

The main types of extruders, differing in the type of material supply, are disk and piston.

Different stages of aluminum extrusion of an aluminum profile

An produttore di estrusione di alluminio begins the extrusion of a profile with warming up the equipment. It is followed by the process of:

• pressing the profile
• then quenching by cooling with air
• straightening the metal profile by stretching
• cutting the profile in accordance with the measured length

The finished profile is subjected to aging - artificial or natural. The type of aging is determined by processing at different temperatures. The quality of the finished metal profile is determined by the absence of scratches and bubbles on the surface of the profile.  The durability of an aluminum or steel profile provides resistance to temperature and operational influences - up to 40 years.

According to expert produttore di estrusione di alluminio, l' “Extruded profiles are subdivided into:

• solid and
• hollow

This process goes according to the type of material - without heat treatment. Also, depending on the presence of a thermal bridge, profiles are divided into warm and cold. A warm system, in addition to the presence of insulation, is distinguished by the fact that it consists of two profiles connected by this insulation.

Ciclo produttore di estrusione di alluminio della struttura dei profili

Le strutture del profilo in alluminio sono realizzate con gradi di alluminio A6, A5, A0, ecc. I profili in lega di alluminio devono essere conformi ai requisiti di GOST 22233-2001. I profili in alluminio metallico devono essere realizzati con nastro di alluminio secondo GOST 13726-78.

"Nastri di alluminio e leghe o fogli di alluminio" Fogli di alluminio e leghe di alluminio "Non sono ammessi sulla superficie dei profili:

• crepe
• la superficie si rompe
• delaminazione
• rischi profondi.

Nel campo delle strutture di contenimento, la gamma dei profili estrusi in alluminio comprende:

1. profili di sistemi architettonici e costruttivi
2. profili per attrezzature commerciali ed espositive
3. profili per sottostrutture di facciate ventilate
4. cornicione e profili ausiliari

An produttore di estrusione di alluminio carries the production of steel profiles in accordance with GOST 30245.

 Types of steel profiles:

• channel
• welded
• I-beam
• closed welded profile

Perché i produttori di estrusi in alluminio utilizzano profili in acciaio?

The use of a bent steel profile due to its greater strength than that of an aluminum profile makes it possible to create visually lighter and thinner structures. Also, a steel profile is used in the construction of, for example, large-span structures.

Special types of metal profiles, architectural profiles are made to order. At the first stage, drawings are developed and approved in accordance with the customer's requirements. Then prototypes of the profile are made. The final stage is the release of the required batch.

Profile pressing

Today, profile pressing is widely used in the construction of structures, and especially in such structures:

• doors
• windows
• partitions

Extrusion of aluminum

The pressing or extrusion process can be applied to both:

• aluminum profiles and bronze
• brass
• stainless steel or titanium

Due to produttore di estrusione di alluminio, l' aluminum extrusion has become famous globally.

How does aluminum extrusion manufacturer develop aluminum and steel?

The extrusion process makes it possible for aluminum extrusion manufacturer to produce aluminum profiles in widths from 10 to 800 mm. Thanks to an unlimited range of various cross-sectional shapes. The cost of tools for making a new extruded section from aluminum is much cheaper than for making a rolled steel section.

Inoltre, il tempo di inattività della pressa di estrusione quando si cambia lo stampo è significativamente inferiore al tempo di laminazione mil. .
