Are you looking for reliable used injection molding machines to buy? With the plethora of used injection casting machines on the market, knowing which one is suitable for your needs can be a challenging task. Since a used injection molder will still cost you a substantial amount of money, you need to make sure that you make the right choice in order to avoid disappointments. Below, we look at some of the mistakes you should avoid as you search for the right injection molding machine for your needs.
One of the mistakes you do not want to make is choosing a machine that uses all-purpose screws. The main benefit of an all-purpose screws is that they can be used with most plastic materials such as PP, PE, PET, Nylon, and PC, and for that reasons they are very adaptable and good for molding companies that mold a range of various materials. However, for a few materials, the component types and efficiency rates will be lesser compared to more superior injection casting screw designs such as the barrier screw. So be sure to think about that first before choosing a machine that uses all-purpose screws.
Another mistake you should not make when looking for good used nissei injection molding machines is choosing one with controlled injection pressure. If you would like to constantly make efficient parts, the molding technique shouldn’t be restricted by the pressure of injection. It is a good idea to have at least ten percent injection pressure aside so that the injection casting machine can automatically tweak to a normal variation in the plastic material thickness. The problem with less injection pressure is that it creates short moldings.
