Customized hollow doors and windows aluminum extrusion mold

Structure of Aluminium Extrusion -Hollow Mold and Solid Mold

Aluminum profile extrusion dies can be divided into solid dies and hollow dies according to the shape of the extrusion section, and hollow dies can be divided into single-hole dies and multi-hole dies.

Hollow mold: It consists of two parts, the upper mold and the lower mold.

The general function of the upper mold is to guide the flow and position the hollow part of the hollow profile.

The lower mold is the outer surface working belt and empty knife.

Solid mold: Only one piece of mold including flow guide and working belt.

Analysis of global aluminum product structure

There are certain differences in the global aluminum product structure between different regions and industries, but the following general analysis can be made:

Aluminum materials and semi-finished products: Aluminum materials and semi-finished products are the main components of the global aluminum product structure. This includes aluminum plates, aluminum coils, aluminum profiles, aluminum foil, etc. Aluminum materials and semi-finished products are widely used in construction, transportation, packaging, electricity and other fields, and are the main products of the aluminum industry.

Aluminum building materials: Aluminum building materials are an important part of the global aluminum product structure. Aluminum alloy doors and windows, aluminum curtain walls, etc. are widely used in the construction field. These products are lightweight, corrosion-resistant and durable, providing good architectural appearance and functionality.

Automotive industry: The automotive industry is one of the important areas of global aluminum product consumption. Aluminum alloy parts are widely used in automobile manufacturing, such as engine parts, body structures, wheels, etc. Aluminum's lightweight properties help improve fuel efficiency and reduce tailpipe emissions.

Packaging Industry: Aluminum packaging products have a wide range of applications worldwide. Aluminum cans, aluminum foil, etc. can be used for packaging of food, beverages, pharmaceuticals and other products. Aluminum packaging products have excellent moisture-proof, anti-oxidation and fresh-keeping properties, which can extend the shelf life of products.

Aerospace field: The aerospace field is an industry with a large demand for high-performance aluminum alloys. Aluminum alloys are used in aerospace for aircraft structures, engine parts, aerospace equipment, etc. High strength, light weight and corrosion resistance make aluminum alloys an ideal material choice.

Aluminium Extrusion Working Principle:

During extrusion, under the strong extrusion force, the ingot is divided into several strands of metal by the knife (bridge part) of the mold and flows into the mold welding chamber. Under the conditions of high temperature, high pressure and high vacuum, the metal is re-welded and flows from the die hole to the needle. It flows out from the formed gap to form a hollow product of the required shape and size. The number of welds in the product is the same as the number of strands of metal flow.
