If you are looking for the right used plastic injection molding machines, you need to be careful with your selection to avoid buying machines that may not be suitable for your business in the long run. There are some things you need to know/ask before purchasing any used machine. You should start with getting the year, make, model, shot, tonnage, serial number, hours and location of the machine along with photos of the machine from all four sides, inside the electrical cabinets, the toggle mechanism, the platens, and the operator station.
