The results showed that the melting rate of SSE with
grooved barrel was significantly higher than that of conventional SSE and the melting rate reached the maximum with a specific combination of the groove number and groove width.
Experimental Investigation of the Single Screw Extruder With Grooved Melting Zone
Since the barrel is essentially a pipe, the pressure from the
grooved feed throat transfers through the barrel, counteracting the discharge-pressure resistance.
Are grooved-feed extruders right for you? In specific circumstances, this design can increase output and reduce melt temperature. But grooved feed throats are not for every application
Grooved systems help alleviate many of the problems associated with using traditional joining methods in the field.

grooved mechanical piping systems were used in all areas of DOKE including HVAC, fire protection and desalination, with pipe sizes ranging from 2" up to 60" (50.8 to 1,525 mm) and pressure ratings of up to 17.75 bars.

Grooved piping systems have been used for more than 85 years, and their list of benefits continues to impress.

This is the reason why many polyurethane covers are
grooved. Presently, polyurethane covers can be manufactured to around 55 P & J and under.
A practical guide to grooving suction rolls
Tests were conducted comparing the new helical design against competitive standard
grooved pins and the company's knurled pins.
Pin re-configuration
The essential feature of the
grooved feed section is increasing the participation of polymer friction in the solid state through the forced movement along the grooves and consequently increasing the polymer flow rate.
Review: increasing the efficiency of the extrusion process
In a conventional Uni-Run conversion, the lower rolls or dryers are
grooved and drilled across the entire roll width, while this is necessary for holding a wet sheet, it is not necessary in the third section where the sheet has more strength.
Sheet wrinkles ironed out at Kruger/Trois-Rivieres: this mill discovered that, with new HS blowbox technology, the price of speed need not include wrinkling
He then turned to an idea that had first surfaced more than a decade before in connection with the diffusion of adsorbed atoms on a
grooved crystal surface.
Surface diffusion with a hop, skip or dip
Eberhard Gruenschloss of the IKT University in Stuttgart, Germany, recently developed the first helically
grooved bimetallic barrels for abrasive materials.

A new mechanism is described that allows adjustment of the groove geometry in
grooved feed extruders.
The Effect of the Feed Section Groove Taper Angle on the Performance of a Single-Screw Extruder
Grooved fixtures were fabricated to compress the o-ring height from 2.62 to 1.75 mm, as in the exciter o-ring groove.
