SCORIM splits the melt into two streams that enter the mold from separate gates.
The Scorim process, according to Grossman, can break through incipient weld lines by oscillating the melt back and forth inside the mold.
* Melt-oscillation molding: Cinpres will provide a rare live demonstration of its Scorim process.
In a previous study, the development of high stiffness composites based on SEVA-C has relied on a strategy that tries to control the structural development during injection molding by means of SCORIM application (4).
An updated Scorim process oscillates the melt back and forth inside the mold with more flexibility and fewer machinery modifications.
For instance, a dramatic increase in toughness was achieved when forming a shish-kebab crystalline structure by shear-controlled orientation in injection molding (SCORIM) in comparison to conventional molding (5).
The SCORIM process uses a special retrofittable processing head mounted between the screw and mold (see PT, Oct.
A route for improving the visual appearance of flake-filled components by developments in molding technology has been proposed (1) and based on the contribution of Bright Surface Molding (BSM) (2) and Shear Controlled Orientation Injection Molding (SCORIM) (3).
Others include the "push-pull" injection molding technique developed by Klockner Ferromatik Desma of Germany (now Ferromatik Milacron) and the Scorim "multi-live feed" injection molding process developed in England and available for licensing from Scortec Inc., Gulph Mills, Pa.
Scortec Inc., a subsidiary of the British Technology Group, displayed for the first time at Interplas '90 its Multi-Live-Feed Molding technology, later Designated Scorim (6, 7, 46), which was developed at Brunel University in England in 1982, and is shown in Fig.
The software will take into account more than just traditional injection molding capabilities; the Institute is giving special attention to the new "multiple live-feed" Scorim process, available in this country from Scortec Inc., Gulph Mills, Pa.
One is the Scorim process, developed at Brunel University in England in 1982 and displayed at Interplas '90 in Birmingham under the name Multi-Live-Feed Molding, or MLFM.
