Colorimetric response (L*, a*, and b*) shows the same important effect of the number of cycles and injection temperature
. Actually, it can be highlighted that this increase is more marked for L* than both a* and b* when both factors come from a minimal level to a maximal level.
After 72 h, the daily peritoneal Kt/V, the accuracy of the injection rate, accuracy of the injection temperature
, safety, and manipulability of the machine were assessed.
As a general rule, look for plastics with the lowest possible injection temperature
and the lowest molten viscosity.
The specimens molded using the lower injection temperature
and lower flow rate (Condition IV) presented lower loss tangent values according to DMA and higher residual stress as shown by DSC, and photoelastic analysis demonstrated extensive birefringence along the specimen.
The injection rate [Q.sub.1] is prescribed and the injection temperature
A steam injection temperature
of 110[degrees]C and a platen temperature of 120[degrees]C (Listyanto et al.
The DSREV extruder is a pre-configured machine with feedscrew and head zone direct injection temperature
control units, a compact base, and simplified cooling and wiring systems.
Although the injection composition, like the injection temperature
, is known to affect the MMP, these simulation studies only considered the effect of the injection temperature
on the MMP.
The injection temperature
control using the induction heating is shown in Figure 1:
That temperature is increased somewhat in the plunger, and increased further to final injection temperature
in the hot-runner nozzle.
