The processing of the appearance of sheet metal chassis is commonly used: cold plate, hot plate, stainless steel plate, galvanized iron sheet, with different appearance processing skills. Cold plate and hot plate can be used for powder or painting. Before the powder, it is necessary to ensure oil-free coating data, no rust, no impurities and a uniform distribution of a layer of phosphate film on the surface of the coating, and improve the adhesion of the coating and Corrosion-resistant, previously only degreased and clean-coated, does not require phosphating, and then simplifies the pretreatment process.
Ways to reduce the damage of sheet metal chassis processing:
The warning light is closed during the use process.
The sliding window is a double pulley that is more than one meter wide or double glazed doors and windows.
Metal stamping parts to avoid rust and corrosion after timing protection.
In the window into the frame door lock handle assembled, to ensure that the switch should be flexible orientation.
The device fastening screws, it is necessary to set the metal lining, the thickness of the lining is better than the hardware inside the two fasteners.
Sheet metal processing to select hardware models, specifications, functions need to conform to national norms and rules, and match the selection of PVC doors and windows.
