Basic knowledge of doors and windows curtain wall

briefly describe the aluminum processing process
Aluminum ingots, Aluminum rods, Aluminum rod preheating,Extrusion, Cooling, Straightening, Fixed length, Artificial aging ,Surface treatment ,Packaging ,Transportation.
Please briefly describe the difference between 6063-T5 and 6063-T6, and between 6063 and 6063A. 
T6 means that when the aluminum profile is extruded, it was treated with water cooling or liquid nitrogen cooling. T5 means it was treated with air-cooled or natural cooling in the air. A on behalf of the different type and content of the alloy resulting in 6063A tensile strength higher than 6063. As for the price, T6 is slightly higher than T5, and 6063A is higher than 6063.

What is the process of aluminum mold opening
Drawing design, tracing ,both sides to confirm, mold design, machining , quenching, line cutting, quenching, assembly, nitriding, testing mold on the machine.
What is the length of aluminum processing
Generally speaking, the largest aluminum processing dimensions of industrial aluminum profile is 7.2 meters and the minimum processing length is 3.2 meters, but there are exceptions
What are the advantages and disadvantages of online LOW-E to offline LOW-E
The advantages of online glass, it can be used with single-chip. It can be laminated plastic. The price is cheaper than offline glass 20 Yuan per square meter. Disadvantages: the color is only included two colors, high transparency and blue-gray, so it is prone to chromatic aberration. 
the advantages and disadvantages of tempered glass 
Advantages of tempered glass: the strength of is 4-5 times the ordinary glass. It can withstand 250-320℃ temperature mutation. 
Advantages of Semi-tempered glass: its strength is between ordinary glass and tempered glass. 
Disadvantages: heat resistance and impact resistance is inferior to steel.

What are the glass thicknesses that can be produced 
① the thickness of commonly used glass: 3mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, 19mm, 22mm, 25mm.
②.Specifications of Aluminum Slabs in manufacturers’ regular inventory: 2440 mm × 3300 mm / 3660 mm, 2100 mm × 3300 mm / 3660 mm.
③. The length of float line can be pulled out (the equipment limit taking CSG as an example):
This is the design and processing size of equipment manufacturers and the specific length should be based the actual strength of the glass, the market and other factors.
