If you have decided to buy a used injection molding machine for manufacturing plastic parts and products in your business, there are a number of things you need to do in order to make sure that the production problems that are associated with secondhand units are minimized. Just like any other second-hand purchase, you need to be extremely cautious in order to avoid ending up with a machine that will create a lot of problems in your business instead of contributing to your growth and expansion. Among the problems that you are likely to experience if you purchase the wrong or faulty machine include slow cycle times, poor part quality, molding below full cavitation as well as constant machine stoppage because of poor part ejection.
In order to but a quality used injection molding machine, one of the things you should do is ask to see the machine producing samples either in person or by video link. It is only by doing this that you will be able to get an accurate idea of cycle time as well as current part quality issues. If the seller is located near you, visit them in person in order to see the machine in action. But if you are buying the machine online or the seller is located far away from you, insists on seeing a video that clearly shows every part of the machine in action before you pay for it. The same way you test drive a car before you buy it, you need to test drive the mold before paying for it.
It is also important to know the age of the used injection molding machine you want to buy. The age of the machine will give you some idea of the possible future problems that you are likely to run into.
