In the absence of NPE due to the pandemic this year, plastic processing equipment manufacturers have turned to virtual press conferences to promote new technologies and products. Last month, Conair introduced its new PipeMaster extrusion line and other innovative products to online reporters and editors of B2B media. Entek's turn this week, there are two projects of interest-the HT72 twin-screw extruder and its vacuum feeding technology. The patent was published on the day of the press conference on June 8.
Entek's Ryley Jones emphasized that the co-rotating HT72 extruder provides the industry's highest free volume at a torque density of 18, as a result of research and development in the past three years. It is the first in a new series of twin screw extruders that Entek has brought to the market.
The HT72 is equipped with a large motor with a relatively small footprint and is intended to be a true workhorse. Jones said this will facilitate "high-volume, continuous production and high-volume processes."
Jones also highlighted various improvements that Entek has designed for the extrusion system, including real-time monitoring dashboards that contain overview data on overall equipment efficiency, oil life and quality, and vibration performance over time. Jones added that the latter is very helpful for preventive maintenance measures.
When needed, it also simplifies maintenance and machine access with error-proof screw elements and shafts and a single tool size for all panels.
At the press conference, Entek also introduced its patented exhaust flow sensor (VFT), which aims to increase the output of twin screw extruders. Entek said that VFT was specifically developed for mixing "fluffy" materials. It also overcomes the problem of fluffy powder being discharged from the air outlet, which is traditionally used to exhaust air associated with fluffy powder.
Dean Elliott, technical processing manager, said in a prepared statement: "If the mixer is challenged by the volume-constrained process when processing low bulk density powder materials, VFT is the solution." "The processor can achieve higher levels. Throughput, up to twice the output rate, without VFT."
VFT is applicable to all twin screw extruders of Entek. The VFT is provided by a license, including pilot tests conducted at Entek to configure the extruder according to the customer's formulation materials and prove to increase throughput compared to traditional atmospheric exhaust. Entek stated that it provided complete documentation of the screw and barrel configuration, as well as on-site process start-up support at the customer's location.
