Aluminium extrusion mold for window insulation profiles

 Introduction to global aluminum ore types

Global bauxite deposit types can generally be divided into two major categories: laterite type and sedimentary type.

The ore of laterite bauxite deposits is mainly gibbsite or a mixed type of gibbsite and boehmite. It is characterized by medium aluminum, low silicon, high aluminum to silicon ratio, and high iron. It is a high-quality raw material for the aluminum industry. , easy to harvest and soluble. The reserves of this type of deposit account for about 88% of the world's total aluminum ore reserves. It is the world's main bauxite deposit. It is mainly distributed in the tropical and subtropical ranges between 30° north and south latitude, generally in the offshore plains and mid-low highlands on the edge of the continent. , mesas and islands are visible.

Sedimentary bauxite deposit reserves account for about 11% of the world's total aluminum ore reserves. This type of bauxite deposit presents a variety of ore types due to different ore control times and regions. For example, China's karst bauxite deposits are mainly diaspore type, and the ore characteristics are high aluminum, high silicon, medium Low aluminum to silicon ratio and low iron; karst bauxite deposits in the Mediterranean and Caribbean areas contain both boehmite, gibbsite and various mixed ores. Global sedimentary bauxite deposits are mainly distributed in temperate areas near 30°-60° north latitude.

Classification of Aluminum Extrusion Dies

1. Classified by the section shape of the die hole compression zone

It can be divided into: flat die, conical die, flat cone die, streamlined die and double cone die, etc., 

2. Classified by the types of extruded aluminum profiles.
It can be divided into bar molds, ordinary solid profile molds, wall panel molds, variable-section profile molds, pipe molds, and hollow profile molds.

3. Classified by the number of die holes

It can be divided into single-hole die and multi-hole die;

4. Classified by the extrusion method and process characteristics
It can be divided into hot extrusion die, cold extrusion die, hydrostatic extrusion die, reverse extrusion die, continuous extrusion die, water cooling die, wide expansion die, horizontal extrusion Machine molds and vertical extrusion machine molds, etc.

5. Classified by the mold structure

It can be divided into integral mold, hollow die, removable mold, movable mold, tongue-shaped combined mold, plane split combined mold, embedded mold, fork mold, front mold, protective mold, etc.

6. Classified by the shape and structure of the mold

It can be divided into a cone mold with an inverted cone, a cylindrical mold with a boss, a cone mold with a positive cone, a conical-middle cone ring mold with an inverted cone, and an inverted cone mold. Cylindrical-conical molds for cones, reinforced molds, etc.

Aluminum alloy is widely used in door and window accessories, mainly in the following aspects:

1. Aluminum alloy door and window frames: Aluminum alloy has high strength, is not easily deformed, is corrosion-resistant, has good weather resistance, and is easy to maintain. Therefore, it is widely used to make door and window frames, which can not only ensure the stability of doors and windows, but also increase their service life.

2. Sealing strips of aluminum alloy doors and windows: The sealing strips of aluminum alloy doors and windows are generally made of hard aluminum alloy and soft plastic, which can effectively prevent the intrusion of rain and wind dust and ensure indoor temperature and humidity.

3. Pulleys for aluminum alloy doors and windows: The pulleys for aluminum alloy doors and windows are generally made of aluminum alloy and plastic. They are light and wear-resistant and can ensure the smooth opening and closing of doors and windows.

4. Hinges of aluminum alloy doors and windows: The hinges of aluminum alloy doors and windows are generally made of aluminum alloy and stainless steel. They are both strong and corrosion-resistant, and can ensure the stable opening and closing of doors and windows.

5. Decorative strips for aluminum alloy doors and windows: Decorative strips for aluminum alloy doors and windows are generally made of aluminum alloy and plastic. They are both beautiful and durable and can improve the overall aesthetics of doors and windows.

In general, the application of aluminum alloy in door and window accessories can not only improve the performance of doors and windows, but also improve the aesthetics of doors and windows.
