BestSub’s two mug coating factories are in Zibo City, also known as the hometown of mug. They cover an area of 150000 square meters in all, mainly producing white ceramic mugs, color ceramic mugs, and enamel mugs. With five highly-efficient production lines, we can produce 180,000 ceramic mugs, 5000 cartons altogether, and over 30000 enamel mugs. This high daily output ensures sufficient inventory and on-time delivery. All our mugs are coated with our self-developed JS coating, which guarantees vivid print-out results, great colorfastness, and washing cycles over 3500 times. After coating, we will examine the mugs through printing test, boiling test, and random quality checks, ensuring they fulfill the standards.
