Hebei Hankai hub rubber seal


As the technical content and the degree of mechanization of doors and windows are not high, most of them rely mostly on the manual operation of the installation workers, which requires the operators to have a good sense of product quality. It is important to strengthen the proficiency of the operators and their product awareness during the production process. High-quality aluminium windows should acquire the following qualities: fine processing, consistent angle (the main frame is usually 45 or 90 degrees), no obvious gaps during the splicing process, good sealing performance and smooth operation.
Common surface treatment processes for aluminum doors and windows are electrophoretic coating, fluorocarbon spraying, wood grain transfer coating, anodizing, and electrostatic powder coating. In most cases, after good surface treatment, aluminum profiles have good atmospheric corrosion resistance. It is moisture-proof, sunscreen, flame proof, aging proof, high-temperature deformation proof, low-temperature embrittlement proof, durable and stable, and suitable for various climates.
