The compact MEDD (Medical Extruder Direct Drive) is built with a replaceable feed section liner and direct drive technology for greater efficiency and materials flexibility. Davis-Standard offers a high-tech melt pump system to maximize stability when pro- cessing sensitive materials. It is ideal for medical tubing and in- dustrial tubing applications that require a cleanroom environment. The SHO (Super High Output) extruder is the latest addition to Davis-Standard’s groove feed technology. The SHO delivers out- puts 20 percent higher than existing groove feed models. It is en- gineered with an improved feed section and high-performance, energy-efficient DSB ® barrier screw. This is especially beneficial for high-viscosity HDPE applications such as pipe extrusion, where lower melt temperatures, reduced power consumption and improved energy efficiency are essential. Maillefer’s pipe and tube extrusion systems support markets en- compassing medical, blown fiber micro duct, heating and plumbing, automotive, micro-drip irrigation, on- and off-shore flexibles, and other specialty and technical goods. These systems are engineered to provide value that makes a difference. Blown film microduct destined for FTTx data networks, multi-layer PEX- AI-PEX composite pipe for heating and plumbing, and multi- functional tubing for automotive applications are examples of the production capacity available from the Maillefer portfolio. In extrusion and liquid coating, Davis-Standard has demonstrat- ed expertise in designing machinery for the circular economy. This includes mono material structures, use of biodegradable re- sins, increasing recycled content, adding functionality with twin screw technology, edge trim recycling systems, and energy- saving design features. For extrusion coating, Davis-Standard collaborates with custom- ers to address precision gauge control, splice speed, simplified changeovers, better adhesion properties, high-speed transfer, and operator safety. In liquid coating, the focus is on helping customers attain the right viscosity, emulsion, pH, and adhesive characteristics for their products. Applications include tapes and labels, silicone-coating products, paint protection films (PPF), and specialty coating markets. Davis-Standard technology specific to the Asian marketplace is the dsX flex-pack™ 300S. This single station extrusion and la- mination line is a collaboration between Davis-Standard’s design teams in the U.S., Germany and China. The 300S can support web widths from 650 to 1,350mm, and is engineered for pro- cessing rates up to 300 meters per minute for paper, film, and aluminum foils with direct gravure primer coating and coextru- sion lamination stations. Another example is Davis-Standard’s new stretch film line with DS S3 winder. The line offers a compact machine arrangement, ease of servicing, excellent profile control, consistent roll quality and an intuitive control package. It is engineered for producing thin films from 31 to 51-gauge (7.8µ to 13µ) at high speeds. The DS S3 winder enables maximum slit widths for hand wrap, machine wrap and jumbo rolls, supporting multiple market seg- ments on one winder. In sheet, Davis-Standard is excelling in high-output packaging,
