aluminium extrusion mold for thermal break door

What are the advantages of broken bridge aluminum doors and windows?

Broken bridge aluminum doors and windows have been a popular type of doors and windows in the past two years and are the first choice material for many people to replace doors and windows. So specifically, what are its advantages that attract everyone? Let’s take a closer look at the advantages of broken bridge aluminum doors and windows.

1. Energy saving

The energy-saving performance of broken bridge aluminum doors and windows is very good. It adopts broken bridge insulation technology, which can effectively isolate the transfer of indoor and outdoor temperatures, thereby reducing the energy consumption of indoor air conditioning and heating, saving energy and reducing the cost of energy consumption.

2. Sound insulation

The sound insulation effect of broken bridge aluminum doors and windows is also very good. It adopts a multi-layer sealing structure, which can effectively isolate the interference from external noise, make the indoor quieter and more comfortable, and improve the quality of life.

3. Waterproof

The waterproof performance of broken bridge aluminum doors and windows is also very good. It adopts a special sealing structure, which can effectively prevent rainwater from penetrating, keep the indoor dry, and avoid losses caused by rainwater penetration.

4. Windproof

The windproof performance of broken bridge aluminum doors and windows is also very good. It adopts a special structural design that can effectively resist the invasion of strong winds and ensure the stability and safety of doors and windows.

5. Beautiful

The appearance of broken bridge aluminum doors and windows is very beautiful. It adopts a modern design concept and can be customized according to different needs and styles, making the doors and windows more in line with personal aesthetic needs and improving the overall aesthetics of the house.

With more than 17 years of aluminium extrusion dies production experiences, JIELIWEI has overcame plenty of tech problems might happen during various Aluminium Extrusion Mould production.JIELIWEI became a professional Aluminum Profile Extrusion Mold supplier in China.

Working Principle of Aluminum Extrusion Die

It is not easy to be widely used in many fields, but aluminum profiles can do it, and it can be seen everywhere in life and work. The prototype of the aluminum profile is not like this, it needs to be processed, and it is extruded through an aluminum profile mold, and this aluminum profile mold also needs to be made first.
Let's first understand the forming steps of aluminum profiles. The aluminum profile processing process includes batching, rolling, extrusion, stretching, forging and other steps. Generally, factories will directly heat aluminum rods, and then extrude them through dies to obtain aluminum profiles of different cross-sections. , To put it simply, it is casting, extrusion and forming.
Extrusion requires an aluminum profile mold. The material of this industrial aluminum profile extrusion mold is H13 steel, and the mold needs to be nitrided before it can be used. Generally, a set of molds consists of three parts: the positive mold, the mold pad and the mold sleeve. The positive mold is composed of working belt, empty knife, deflector and other parts, and each component has its own function.

When extruding, the ingot is still under the strong extrusion force, and is divided into several strands of metal by the knife (bridge part) of the mold and flows into the welding chamber of the mold.
 The formed gap flows out to form a hollow product of the required shape and size, and the number of welds of the product is the same as the number of strands of the metal flow.

Quenching Furnace  

The quenching furnace is a furnace that heats the workpiece before quenching.

Quenching is to put the workpiece into the furnace and heat it to the quenching temperature above the critical point and keep it for a period of time, then quickly take the workpiece out of the furnace and put it into the quenching liquid (oil or water) for quenching.

The heat source of the furnace can be electricity and fuel, and the temperature can be measured by a thermocouple.

Furnaces using electricity, gas, and liquid fuels can be automatically controlled and regulated by instruments.

Our quenching standard:
After heat treatment for 14 hours, the hardness reaches 50-52 degrees.

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.
