Here are the main factors that affect the aluminum profile frame:
The first category: raw materials
First, extrusion defects.
Aluminum extrusion process due to the machinery and equipment is perfect, processing technology is mature and staff operation is improper, will lead to aluminum profiles such as white spots, inclusion, delamination, color difference, distortion and other defects, affect the quality of aluminum profiles.
Second, thin oxide film thickness.
General standard industrial aluminum profile oxide film thickness should not be less than 10um (micron). If the thickness is not enough, the surface of aluminum profile is easy to rust, corrosion, shorten the service life. And there are some proletariat name, site, production license, certificate of aluminum profile manufacturers, in order to save costs, its oxide film thickness is only 2 to 4um, some even no oxide film. It is estimated that if the oxide film thickness is reduced by 1um, the power consumption cost can be reduced by more than 150 yuan per ton of profiles. So they can make a lot of profit from it, which is why some customers say that the price of X company is lower than ours.
Industrial aluminium profile
Third, the chemical composition is not qualified.
And some manufacturers in order to retain customers, do not hesitate to incorporate a large number of mixed aluminum, waste aluminum aluminum profile can greatly reduce the cost, but will lead to industrial aluminum profile chemical composition unqualified, seriously endanger the life of aluminum profile.
Fourth, reduce the wall thickness of the profile.
Some manufacturers will make the wall thickness of aluminum profiles insufficient, originally is 1.5MM thick aluminum, in order to save costs, they only do 1.2MM, in this way, the price of an aluminum must be much cheaper. But the customer does not know, still think to find a good supplier, in fact, was cheated to help him count the money.
The second category: accessories
There are many kinds of industrial aluminum parts, different parts will be used in different parts, so each part is in their position to play light and heat. The types of these accessories mainly include: Built-in connector, square nut block, metal shoe, shrapnel nut block, Fu Ma wheel corner slot connector, three-dimensional corner connector, anchor corner piece, active hinge, slot connector, end cover plate, steering corner piece, flat sealing slot, common handle, door suction, spacing connecting block, hinge, metal hinge, casters, compound casters, etc.
The first is an aluminum rectangular seat, which, as the name suggests, is made of aluminum. This accessory is relatively strong and stable, so it is often used for medium and high connection. When using this kind of accessories, we must be careful. First of all, square nuts, or t nuts, diamond nuts are placed in the slot of the profile, and then use stainless steel screws to connect.
The second is aluminum alloy handle, the main material of this material is aluminum alloy, the main use is used for opening doors and Windows, it has strong practicability, and adaptability is also very strong. When in use, the square nut is accurately placed into the profile slot, and then the wood is properly connected with the handle with the hex screw.
The third is Angle aluminum connecting seat, its main composition material is aluminum alloy, mainly used for moderate strength, high strength connection. This material is made of equilateral Angle aluminum, which can be used to fix the guard plate after drilling a gap in its side.
The fourth is strong nylon. It is made of materials different from the above three, it is mainly made of nylon. In practical application, it is generally used for opening doors and Windows. Use the same method as the aluminum alloy handle, put the nut into the profile slot, and then connect with the handle, tighten it.
