At the beginning, a brief introduction of company background, various types of manufacturing processes and different air ventilation products was given. Mr C M Wong, Director of Pacific Wing Shing, also shared his valuable experiences on how to achieve the just-in-time manufacturing process so that each of their specialised departments can provide professional services to satisfy customers' needs and ensures the products remains in high quality. After that, we had a chance to take a look at the production lines and various manufacturing machines such as Plasma CNC cutter, spiro stitch welding machines, automatic flange producer and rectangular duct closure system etc. During the visit, members learned more about the manufacturing of rectangular duct, oval duct, air diffuser, dampers etc and acquired knowledge on the key factors that would affect the quality of these air ventilation products.
