Right: Bausano has developed a new genera- tion of extrusion heads for PVC and polyolefin pipe
Automated for hoses Maillefer’s parent company, Davis-Standard, recently introduced its 4000AG automated crosshead for elastomer hose applications. Based on its earlier 2000, 3000, and auto 3000A
designs, the crosshead delivers closed loop, stepper-driven automatic control of tube concen- tricity and wall thickness in a hands-free, low maintenance package, says the company. “Hose producers can improve product dimen- sional qualities while increasing material savings during start-up and product size changeovers,” said Joe Wnuk, vice president of Davis-Standard’s elastomer systems division. “More consistent hose, minimised scrap, and ease of operation all equate to cost savings and more consistent manufacturing practices.” The 4000AG also helps to boost workplace safety and user- friendliness, he said. The design is engineered to minimise operator involvement and the use of hand tools. Its fixed die eliminates the need to loosen or tighten bolts for fine-tuning. For concentricity adjustment, operators use a joystick instead of manual wrenches. Wall thickness modifications are stepper-driven, eliminating the need for hand tools or thickness measuring devices.
In terms of retrofits, many existing 2000 and
3000 heads can be retrofitted to take advantage of the 4000AG’s automated design features. These require the current 2000/3000 standard tooling.
New generation Bausano has developed a new generation of extrusion heads for making PE, PP and PVC pipe.
In particular it offers a range of models for making PVC pipe, either double (up to 110mm) or single (from 10 to 800mm) output, for a maximum production capacity of 2,000 kg/h. For extruding polyolefin (PO) pipes, Bausano says its technology is designed to ensure high hourly throughput with reduced energy consumption. The die heads stand out for their compact design for monolayer or multilayer production. These are radial spiral – ensuring better melt distribution within a smaller volume and with reduced pressure build-up – or helical spiral. These are modular systems where the number
of layers can be easily increased by adding special modules. A combination of helical and radial
long time experience leads to best
performance extruders regardless the application
