When you ask quotation from factories, most of them will indicate the production lead time in the quote sheet. Different production field will have different lead time: For example the shoes manufacturer always asked a 90days lead time. For solar lighting, normally we need 40-60days, depends on if it’s new order, or if it’s our hot season/low season. An efficient production management team includes Purchasing Dep., IQC, IPQC, Assembly line, Logistic Dep. Etc,  Team spirit, Quality control is the essential request. An efficient production management team will arrange the process accurately. As we know, production is very complex, we need organize materials like plastic, die casting aluminum, stainless steel, glass, circuit panel, screws, color box, instruction manual, master cartons etc… on time. We cannot finish final packaging even lack of 1piece of small screw. That’s why we always asked customers to cooperate with us to provide the package files (instruction manual, artwork and shipping marks) ASAP. www.aubenar.com
