Quality Xingfa aluminium profile's process

XINGFA Aluminum Co., Ltd. was established in 1984 and has a history of more than 30 years. It is the earliest manufacturer of aluminum doors and aluminum profiles in China. Xingfa is well-known and large-scope, specializes in producing aluminum for both architectural and industrial fields.

 

 

Imported Xingfa aluminum profiles are manufactured from high-class aluminum alloy with light weight, easy for production, construction and installation. Hollow cavity structure for high strength, firmness against warping and 2 reinforced grooves are featured prominently. Xingfa Aluminum is used in a variety of door designs including: casement windows- doors, sliding windows- doors, folding doors, curtain wall ... Besides traditional designs, currently, architects, designers and construction companies can transform aluminum profiles with hollow cavities into modern, precise and aesthetic arches by aluminum bending machine to create a special new highlight for windows- doors and panoramic of projects. In order for customers to know well about the cleaning process of Xingfa aluminum profiles before moving products to paint, we will introduce the treatment process at the factory in Guangdong generally. This is an important stage of production that is different from other aluminum profiles, which makes Guangdong Xingfa quality.

 

 

Aluminum profiles after extrusion and before painting, their surfaces will treated by cleaning, redox,  anticorrosion and chrodium coating on 2 sides of every profile's surface and interior. This stage increases adhension between profile and powder coating, doesn't peel easily like normal profiles. 

Profiles are embedded in dark golden liquid pool (horizontal line). Profile's interior has lighter bronze color because of horizontal chromium coating stage but surface in contact with paint meets technical standards completely. The paint will not peel off

There are some minor errors in the horizontal stage, bronze color of interior is uneven. there are some places where were embedded in liquid pool and coated evenly are very dark bronze. Please watch the video you will understand. However, products are manufactured in industrial line, it is impossible to be 100% absolutely error free.

Uneven bronze color of profiles are from arrangment profiles on shelfs to embed in the pool, embeded time is in limited standard, there are some profiles what don't have good contact with liquid and not enough time in embedding so even color will be happened, or surfaces of profiles were not cleaned well, they can be unsmooth painting.

Method of cleaning in the vertical line by hook (not in horizontal line in liquid pool) is by gun system, gun will be moved from top to bottom. First, the gun is hung up and goes into the chemical furnace to cover with the 1st chemical layer deoxidize, prevent corrosion for aluminum profiles, then will move to the furnace to clean with water for the first time, the second time to finish cleaning with water, the aluminum profiles are continued to move to the chemical furnace to cover the chromium 2 surfaces with gun system moving from top to bottom, but in this method of cleaning, the interior of aluminum profile is uneven and light bronze color, less than horizontal line. But the outside surface of the aluminum profile always qualifies chrome coating to paint firmly on the surface of the aluminum profiles.

 

 

There are 2 powder coating stages before finishing profiles: Vertical stage and horizontal stage 

 

There are some minor errors in horizontal stage as below:

Bronze color of profile's interior is uneven, Please watch the video you will understand. However, products are manufactured in industrial line, it is impossible to be 100% absolutely error free.

There are some minor errors in vertical stage as below:

When profiles are hooked wrong positions, gun can not paint even color or not paint complete when it moves from top to bottom.

Currently, Xingfa alumnium profiles have over hundred different colors in the markets. Every market will have itself popular color. There are 4 popular colors in Vietnamese market (White.P040- Grey.PH07- Brown.PB09- Black.P024). In another markets, another colors can be popular, the different colors deviation is 10- 15% with different names. Recently, common mistake is PH07 difference because of worker's mistakes in paint. We will update color list then customers will understand better why color was wrong.
