The aluminum curtain wall is a non-structural outer covering of a building’s facade designed to protect the building from the elements and create an aesthetically pleasing appearance. It is typically composed of aluminum frames, glass, and other cladding materials. The term “curtain wall” refers to the fact that the exterior wall is non-structural and does not support the load of the building. Instead, it hangs like a curtain from the building’s structure.

Here are key features and components of an aluminum curtain wall:

Aluminum Frames: The main structural component of the curtain wall is the aluminum frame. These frames are lightweight, durable, and resistant to corrosion, making them ideal for external applications. The frames are often designed to accommodate the weight of the glass or other cladding materials.

Glass Panels: Curtain walls are characterized by large expanses of glass, providing natural light and offering views from inside the building. The glass used can vary in terms of thickness, insulation properties, and coatings to control factors like solar heat gain and glare.

Spandrel Panels: In addition to glass, curtain walls may incorporate spandrel panels, which are non-transparent panels that cover the areas between floors or between vision glass. These panels contribute to the overall appearance of the facade and help create a uniform exterior.

Seals and Gaskets: Given that curtain walls are exposed to external weather conditions, they include seals and gaskets to prevent water and air infiltration. Proper sealing is crucial for maintaining the building’s interior climate and protecting against leaks.

Thermal Breaks: Aluminum curtain walls often incorporate thermal breaks, which are non-conductive materials placed between the interior and exterior aluminum sections. This helps reduce heat transfer, improving the overall energy efficiency of the building.

Structural Support: While the curtain wall itself is non-structural, it requires a support system attached to the building’s structure. This system is responsible for transferring the loads (such as wind loads) from the curtain wall to the main building structure.

Aluminum curtain walls are popular in modern architecture due to their versatility, sleek appearance, and the ability to create visually striking facades with ample natural light. They are commonly used in commercial buildings, office towers, and high-rise structures. The design and engineering of curtain walls consider factors such as aesthetics, structural integrity, energy efficiency, and environmental performance.

Thermal break aluminum window Jamb have mainly three processes: 45 °cutting,milling holes(glue injection hole, pin hole, mullion connection hole, water drainage, mounting hole ), corner crimping

JMD recommend two type of machines for 45 ° cutting function& milling holes function

JMD recommend Heavy duty Corner Crimping Machine(LJZJZ-150) for corner crimping function

Aluminum window frames are widely used in the construction industry, with the advantages of lightweight, durable, beautiful and so on. This article will introduce the manufacturing process of aluminum window frame in detail.

1. Prepare raw materials
The main raw material of aluminum window frame is aluminum. Aluminum profiles are usually made of aluminum alloys, which contain elements such as aluminum, copper, and magnesium. These elements can improve the physical and chemical properties of aluminum, giving it better corrosion resistance, strength and plasticity.

2. Cut and punch
Extruded aluminum profiles need to be cut and punched to get the desired size and shape. This process is usually done using a CNC machine that allows precise control of the size and position of the cut and punch.

3. Assemble
Aluminum window frames are usually assembled using screws or rivets to join the aluminum profiles together. During the assembly process, it is necessary to ensure that the connection between the aluminum profiles is tight to prevent water leakage or air leakage.

4.Quality inspection
In the manufacturing process, the quality of the aluminum window frame needs to be inspected to ensure that its size, shape, surface treatment and so on meet the requirements. Common inspection methods include dimensional measurement, appearance inspection and corrosion resistance test.

Together, these steps guarantee the quality and performance of aluminum window frames, making them a widely used material in the construction industry.

Aluminium Window Production Line, Aluminium Window Fabrication Machinery

Aluminium Window Production Line is the highly technological solution for the production of door and window frames. It combines superior versatility and high production levels thanks to the total integration of various machines. System lines perform all the operations of planing, tenoning, drilling-routing and profiling thus completing the work-pieces in all their parts.

Doors and windows are a type of material that we will inevitably contact and purchase when we are decorating the house. Now the system doors and windows are very popular on the market, so what do the system doors and windows mean?

System doors and windows refer to the perfect organic combination of a performance system. It needs to consider a series of important functions such as water tightness, air tightness, wind pressure resistance, heat insulation, sound insulation, and anti-theft, as well as the performance of equipment and materials. The synthesis, and finally form a high-performance system doors and windows.

The design and production of the doors and windows of the system have been scientifically and rigorously designed and tested. It is necessary to consider the cooperation of equipment, materials, processes, etc., and pay great attention to adaptability and integrity. The impact greatly affects the functionality of doors and windows.

The high performance of the system’s doors and windows is a major advantage. The doors and windows of the system generally use double-layer hollow tempered glass, and the noise will be weakened when passing through the glass, thus forming a good sound insulation effect. The close cooperation of aluminum, glass and hardware can achieve superior sealing performance, and the safety, wind pressure resistance and thermal insulation of the system doors and windows will be better than ordinary doors and windows.

At present, aluminum doors and windows are very popular in the selection of home decoration products. First, because aluminum is very light, it is the best choice for frame doors and windows; second, aluminum can be customized and matched according to specific requirements.

1. Energy saving and environmental protection. Aluminum profiles have superior corrosion resistance and high strength-to-weight ratio, making them the best choice for door and window materials. Compared with the use and loss of doors and windows of other materials, aluminum alloy doors and windows have a long service life and are also the correct choice for family cost investment.

2. Sturdy and durable.Aluminum profiles are very strong and can be processed into different sizes and shapes.After surface treatment, aluminum profiles of different colors can be obtained, which are more suitable for different home improvement styles.Unique doors and windows can be designed according to the different hobbies and aesthetic views of the owners.

3. High recovery rate.Aluminum sliding windows can be recycled and reused, which is an energy-saving material.Aluminum doors and windows do not rust, fade, or fall off, and require almost no maintenance. Spare parts have a very long service life and save maintenance costs.

Aluminum windows & doors have ultra-light quality,which is convenient for production, transportation and installation. At the same time, its price is relatively affordable. Therefore, no matter which aspect is considered, aluminium doors & windows are the preferred products of the majority of customers and are deeply loved by customers.

In addition, compared with other window &door products, aluminum doors & windows use more environmentally materials and friendly accessories, which meet the requirements advocated by the state and are also an innovative direction of it.

The milling of two kinds window machines can be universally which both are used for milling sinks and keyholes. UPVC milling machines are dedicated. While single-axis copy routers and double-axis copy routers can be used in general.

The difference in the angle connection determines the difference in the machine used. Aluminium windows are connected by corner crimping machines, while UPVC windows are welded.These two window machines are completely different.

Since the aluminum doors and windows need to use the corner connecter when connecting the corner, it has a special machine for cutting – corner connecter cutting saw. As the connection principle of window mullion ,frame and sash are the same，the connection between the two is the same .

The aluminum window machine uses end milling machines, while UPVC machine uses V notch saws and welding machines. Therefore, it is recommended that do not mix these two kind of machines.

JMD is a leading manufacturer of aluminum window machinery in China. We mainly focus on the R & D, production and sales about thermal break aluminum window machines. Generally, a production line will include 6main machines: double miter saw, corner crimping machine, corner connector saw, punching machine, end milling machine and copy router/CNC router. Besides of the machines above, some other machines and tools are also useful. Let me introduce you some of them.

1. CNC Milling Machine(X axis stroke to be 0.8m or 1.2m) SKZX-A3-CNC-1200

Usually, for standard model of CNC milling machines, its X axis stroke is 3200mm which makes it possible to process both window and door profiles. If you mainly make aluminum windows which not in large size, it’s not necessary to invest such a big machine. SKZX-A3-CNC-1200 can be a good choice. It is much more efficient than the manual copy router and doesn’t cost highly.

2. Chop Saw for Glass Bead Cutting

The glass bead profiles are usually packed tightly with plastic film or paper. They can be cut by double miter saw without unfolding the package. After the window/door frame are finished, the length of inner frame sides are not always the same as design. To ensure the glass beads are not too short, we usually make the real cutting length a bit longer(few millimeters) than the design value and use a chop saw to cut them into the exact length when install them to the window/door frames. So, the chop saw is a very important tool for aluminum window production.

3. Multi-head Drilling Machine LMZZ6A-13

The machine is mainly used to make the installation holes to the window or door frame profiles before corner crimping. The drill heads can work together or separately as required. Drill heads quantity usually is 6, but other quantity is also optional. We can also use it to make mullion installation holes.

4. Trolleys

With a normal aluminum window production line, you need to take much time to transfer the aluminum from station to station, no matter the raw material, pieces been cut or aluminum frames. So you have to develop different kinds of trolleys for different materials. If you don’t want to make them by yourself, you can buy from JMD or other suppliers.

Aluminum window especially the thermal break window is more and more popular in today’s world. People love it because of its excellent thermal insulation properties. Besides of the good design and high-quality materials(aluminum profile, glass, strips, sealant, etc), what else make the thermal break window function so well? The answer is the way to make the windows.

To make aluminum windows, we must need aluminum window machinery including aluminum profile cutting saw, crimping tool, aluminum punching machine, aluminum bending machine, end milling machine an so on. For all the machines above, the aluminum profile cutting saw is the most important one. Usually, the window jamb and sash profiles are jointed at 45degree angle. And the mullion profiles are connected to the jamb at 90 degree. So, cutting 45 degree and 90 degree angle is the basic function required for the cutting saw. The double head miter saw is made for this purpose.

JMD is the leading manufacturer of aluminum window machinery in China. We have 2 models of double miter saw optional:

1. LJJ2AS-500X4200, CNC controlled. The right machine head can move automatically to reach the cutting length. Cutting length can be preset through the touch screen. It’s easy to operate, especially when you have multiple cutting lengths.

2. LJJ2AX-500X4200, Non-CNC. The right machine head should be manually moved to reach the cutting length. The real cutting length will be displayed by a digital screen. Compared the the CNC saw, it is more simple and stable. More importantly, its price is not high.

Which saw will you choose? Feel free to contact us if you’re interested.
