Aluminum thickness error - GB aluminum thickness deviation!

Often some are new decorative materials aluminum veneer customer, after receipt of the goods, they begin to check the product's quality, size, surface colors including aluminum, and thickness of the product there is no error, and so on.
I believe we can understand this, but there are always some customers do not understand the material and found that products tend to have a thickness of 0.1 to 0.15 mm plus or minus about the error than the actual demand!
It is this overall thickness almost can not count small error, customers feel aluminum veneer manufacturers cut corners,
In fact, this error is permissible, please Baidu about [building decoration quality acceptance] or reference GB GB50210-2001, which has the relevant technical information!
 
 
Profile aluminum veneer material thickness
Aluminum veneer finished thickness from 1.5mm 2.0mm 2.5mm 3.0mm 4.0mm thickness and other five commonly used, but when manufacturers started production, the use of customer needs than the thickness of about 0.1 mm thin material processing,
Because the surface of the aluminum veneer After baking, the finished product will increase the thickness of 0.1mm-0.15mm high temperature baking thermal expansion phenomenon, plus a little bit of paint coating thickness, which happens to be close to the customer needs thickness specifications ʱ??
Mold problems caused by errors
Mold also causes loss of error, such as a production 2.0mm thickness of aluminum mold, manufacturers generally from 1.85mm thickness on mold, because Abrasives with a long time there is loss and deformation,
After a certain mold production, aluminum finished products to the thickness of about 2.1, we should scrap! General This is also gradually formed aluminum veneer manufacturers, not only increases the life of the mold and finished deviation of plus or minus 0.15mm, and also just within the range of the national standards in!
