All slot-die heads require fitting kits and shim kits to operate. The small laboratory scaled heads are available in standard widths of 50 mm, 65 mm and 115 mm allowing for working widths of a single 10 mm or 13 mm stripe, 50 mm working width or 100 mm working width respectively. The dead volume for the laboratory slot-die coating heads ranges from hundreds of microliters to a few milliliters. Our larger pilot and industrial scale slot-die heads have a large dead volume starting from around 2 mL pr cm of coating width. This implies that our range of coating heads for coating in a full width of 304.8 mm have a dead volume of approx. 60 mL. The slot-die heads intended for operation at low pressure with low viscosity inks are comprised of only two parts which greatly simplifies assembly, disassembly and cleaning. They can be operated with a single shim or with a shim kit comprising shim and meniscus guide for coating stripes at low web speeds (0.1-5 m min-1). The light weight alloy and composite heads allow for ultrafast positioning on automated coating platforms.
