If the factory’s machines are free, it may be possible to finish an express job on the same day, but if the machines are crowded, it will be difficult to achieve a short delivery date. In addition, processing under such conditions may result in lower quality and costs, so if you need a short delivery date or an express order, it would be best to contact the processing factory in advance and discuss the best way forward.
The more difficult a shape is to process, the longer it takes, and in some cases, special tools may be required.
