‘SSSP’ Technology Is Finally Commercial
By Jan H. Schut Solid State Shear Pulverization, which chills a co-rotating twin-screw extruder below the softening temperature of plastic rather than allowing it to melt, is finally commercial after more than 20 years of R&D. Zzyzx Polymers LLC, Allentown, … Continue reading
‘Exjection’ Molding Comes into Its Own
By Jan H. Schut At least two commercial technologies combine extrusion with injection molding to fill molds with much lower pressure than conventional injection molding. One was recently introduced by Extrude to Fill LLC, Loveland, CO (www.extrudetofill.com), which melts plastic … Continue reading
Unusual ‘Extrusion’ Molding Is Commercial
By Jan H. Schut Low-shear, low pressure “extrusion” molding machines developed by Extrude to Fill LLC, Loveland, CO (www.extrudetofill.com), a 2014 start-up, have been commercially molding tiny acoustic parts since 2015. Extrude to Fill’s process melts plastic without motion using … Continue reading
New Shapes for Conformal Cooling
Conformal cooling channels in injection molds have been built by additive manufacturing, or 3-D printing, developmentally since the late 1990s using successive thin layers of metal. Continue reading
