Q:Door and window hardware accessories

Door and window hardware accessories process 1, the production process quality doors with metal surface smooth, smooth, no pores, burrs, defects and other phenomena, the details of the process, especially see the excellent. This and high-quality hardware products and more use of large forging machine forging is not unrelated to the high strength of the mechanical force to make the material density becomes very high, and then after dozens of precision machine polishing polishing process to make the product as bright as a mirror Extraordinary effect. In contrast, the poor use of hardware products due to the use of small die-casting machine and simple lathe processing production, the general structure of loose, visual inspection that can be found on the surface of the pores, silk, cracks and so on and uneven phenomenon. 2, electroplating process High-quality doors with metal products, the electroplating layer is often bright and uniform, natural color, good density, the coating has a solid sense of visual inspection. The poor quality of the door with the hardware products, the coating shiny dark, thin coating within the short term easy to rust, wear, peeling, blistering.
