How does Aluminum Extrusion Manufacturer Carry Extrusion Process?

What is Aluminum Extrusion?

For fabricante de extrusión de aluminio, extrusion is a process for making profiles with a fixed cross-section. The material is pushed or pulled through a die with a cross section. On this page we would like to cover all topics related to aluminum extrusion, from 3D CAD design to special technologies.

How does aluminum extrusion manufacturer carry extrusion process?

Extrusion technology for aluminum profiles consists of the following points:

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 fabricante de extrusión 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 fabricante de extrusión de aluminio 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 fabricante de extrusión de aluminio, “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.

Aluminum extrusion manufacturer cycle of profiles structure

The profile structures of aluminum are made of aluminum grades A6, A5, A0, etc.. Aluminum alloy profiles must comply with the requirements of GOST 22233-2001.  Metal aluminum profiles must be made of aluminum tape in accordance with GOST 13726-78.

"Tape from aluminum and aluminum alloys or sheets "Sheets of aluminum and aluminum alloys". The following are not allowed on the surface of the profiles:

• cracks
• surface ruptures
• delamination
• deep risks.

In the field of enclosing structures, the range of extruded aluminum profiles includes:

1. architectural and construction system profiles
2. profiles for trade and exhibition equipment
3. profiles for ventilated façade substructures
4. cornice and auxiliary profiles

An fabricante de extrusión de aluminio carries the production of steel profiles in accordance with GOST 30245.

 Types of steel profiles:

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

¿Por qué el fabricante de extrusión de aluminio utiliza perfiles de acero?

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

Hoy en día, el prensado de perfiles se usa ampliamente en la construcción de estructuras, y especialmente en tales estructuras:

• puertas
• ventanas
• particiones

Extrusión de aluminio

El proceso de prensado o extrusión se puede aplicar a ambos:

• perfiles de aluminio y bronce
• latón
• acero inoxidable o titanio

Debido al fabricante de extrusión de aluminio, la extrusión de aluminio se ha hecho famosa a nivel mundial.

¿Cómo desarrolla el fabricante de extrusión de aluminio el aluminio y el acero?

El proceso de extrusión hace posible que el fabricante de extrusión de aluminio produzca perfiles de aluminio en anchos de 10 a 800 mm. Gracias a una gama ilimitada de varias formas de sección transversal. El costo de las herramientas para hacer una nueva sección extruida de aluminio es mucho más económico que para hacer una sección de acero laminado.

Moreover, the downtime of the extrusion press when changing the die is significantly less than rolling mil time. .
