If you produce a mobile phone case, the main equipment are: punch, peeler, high-end car, flatbed car, and bronzing machine. Any bigger, you need a computer car. If you make other gadgets, you won't mention them one by one. How much you invest depends on how big you make it. If the liquidity of computing equipment with about 30 people is added, it is more than 65438+ 10,000. You do the processing, others pay. It won't cost much, as long as you have enough orders. If you have more orders, you can send them out. The processing plants outside are scrambling to help you. The economy is not good this year, and many people have nothing to do. As for the process, the first is to make paper samples. After the customer confirms the sample, place an order and make a knife mold. After the knife mold is made, they will make prenatal samples. After confirming the prenatal samples, they began to produce. First, they will use a punch to punch holes in the material. After that, they will be placed on the table, glued, folded, ironed or stamped, stitched, bagged, turned up, packaged, cleaned and loaded. I also make mobile phone cases, hehe, I hope it will help you.
