Foshan Wanqing Materials Co., Ltd., located in Shunde Lecong, Guangdong steel wholesale market, is a steel trading enterprise integrating steel sales, processing and distribution. We cooperate with professional steel processing factories to provide processing services for customers, including:
Striping: according to the customer's requirements, the large strip is divided into small strips, such as 0.5 * 1000 * C. with a width of 1000mm, it can be divided into specifications within 1000mm.
.Flattening: the coil plate is cut into a flat plate, that is, a coil of steel plate is cut into a rectangular or square flat plate, or a large plate is cut into a small plate
Sub volume: large volume is divided into small volume, and the specification remains unchanged.
Flash: remove the burr of the coil.
Rewinding: also known as rewinding. A roll of open plates is rolled up again. Generally, it is opened to see if the steel plate has quality problems
Longitudinal shear: trimming, for flat plate
Straightness: flatten the uneven plate
There are also rough machining: stamping, bending and stretching. Concave parts such as washbasin are deep drawing.
The black oven shell is matte black, matte black and high gloss black color coated plate based on dx51d or dx53d galvanized plate. The color and grain can be customized according to customers' needs.
There are many differences between the color coated plate and the ordinary steel plate during processing. Because there is a layer of film on the surface of the color coated plate, attention should be paid to making products for different purposes through cutting, punching, bending and connection, so as to prevent the damage of the film during processing from affecting the appearance and service life of the product.
Cutting processing: the burr of the cutting section shall be reduced as much as possible, the metal powder during cutting shall be removed, and the rubber pad shall be paved below to prevent the surface from being damaged during stacking and processing;
Bending processing: the dirt and rust on the stamping die, punch and other parts shall be removed before processing; The temperature during processing should be controlled above 5 ℃; If rolling processing is carried out, the roll (quenched steel, die steel, etc.) shall be made of hard materials or the roll surface shall be plated with hard metal;
Pressure processing: during pressure processing, the base plate and coating type of color coated steel plate must be carefully selected; In addition, careful processing shall be carried out. The surface of the metal mold shall be particularly smooth. According to the situation, a protective film shall also be pasted on the surface of the color coated steel plate to protect the coating;
Connection: the color coated plate can be mechanically connected, welded and bonded. However, at present, the welding equipment and technology of the color coated plate are still in the research and experimental stage and are not mature. Users should try to adopt the mechanical connection method.
Cut section protection of color coated plate: when designing products, try to place the cut in the concealed part; When using the color coated sheet with galvanized sheet as the base plate, because zinc has a sacrificial pole to protect the steel, it is generally unnecessary to make special treatment on the cut section. The cut section shall be protected only when it is in contact with drugs, corrosive gases or used in other harsh environments.
