In-line sputtering process boosts plating efficiency


Vacuum coating of plastic substrates using conventional batch process machinery requires a significant investment on the part of the processor as well as high labor requirements for manual loading/unloading of parts. By moving this process in-line and machine-side, The Japan Steel Works (JSW, Tokyo) reckons it has a lower cost and more flexible solution.

At IPF, the vacuum coating unit from Watanabe Co. (Yokohama, Japan) sat alongside a J55-AD-60H all-electric JSW injection press molding toy blocks from polycarbonate (PC) resin in a four-cavity mold with a 20-second cycle time. These blocks were...
