Davis-Standard LLC has introduced a spiderless foam sheet die for processing polystyrene and polyethylene.
The spiderless die eliminates spider weld lines and provides a uniform basis weight and thickness over the entire width of the sheet—eliminating the need for edge trim.
The die also has a unique mechanism to adjust die lip gap opening and closing, enabling the operator to make modifications during production, without stopping the sheet line. That control is enhanced by an external die lip concentricity adjustment
Other features include streamlined flow channels, up to three zones of temperature control, nickel plating on all wetted surfaces and aluminum constructed internal and external air rings.
Modular die lip inserts allow for easier, inexpensive replacement of a damaged or alternative lip die design. A die lip fast gap allows for quick cleaning of contaminants.
Davis-Standard of Pawcatuck, Conn., offers die designs in thicknesses from 0.04-inch to 0.5 inches thick, and widths from 24-120 inches.
