If you really want to be an injection molding factory, I suggest you find a few customers first and help them do OEM work. Then you can find a new patented product yourself, or buy a new product, and then process it yourself and wholesale it to the seller, which will make a big profit. It is estimated that it will take at least four years to recover the cost. Therefore, it is suggested that if there are other suitable projects, don't invest money, because the profit rate is too low. If you don't believe me, you can find a plastic factory (except for processing auto parts) and know everything for a while. Don't trust your own forecast plan, but see the actual profit. After all, the money in the pocket is real, and even the best plan is just an armchair strategist.
