Buying used Nissei injection molding machines can be easy if you know what to do. Since this is a second-hand purchase, you need to be extra careful in order to avoid regretting your decision. The following are some of the things you should do for your purchase to be worthwhile.
First of all, make sure that you check the shot size of the used injection molder you want to purchase. . Remember that if you need guidance at any time, the plastic injection molding machine company that you will purchase your equipment from will help. As for the shot size, it refers to the maximum amount of plastic that the machine is able to inject going into the mold cavity. To be on the safe side, consider purchasing a machine that can produce between 30 and 40 percent greater shot sizes compared to what the part requires.
When looking for the right used Nissei injection molding machines to purchase, also consider tonnage. This simply refers to the clamping pressure that the equipment delivers. The number of tons that the machine is able to produce when pressing the platens together is how tonnage is measured by experts.
Last but not least, make sure that you check the ejector stroke of the machine you want to purchase. The ejector stroke refers to the action of the machine as it ejects the completed workpiece from the platens. In other words, after the plastic heats, moves into the mold, shapes the product, and then cools down, the ejector stroke releases the finished product. Ejector pins are used in this process, something that helps with the pushing action.
