Sensitivity of the Stability of Isothermal Melt Spinning to Rheological Constitutive Assumptionsis predicted above a critical value of a dimensionless group λv./L, where v. is the initial velocity, L is the length of the melt zone, and λ is the relaxation time evaluated at v./L. Cooling is usually stabilizing.

Flow in Injection Mouldsis interface, which is frozen into the moulding, has become known as a weld, or knit, line and its effect on the overall strength of a plastic component is becoming the source of much interest, particularly as there is relatively little information in the published literature.

Design of Polymer Melt Extrusion Dies to Avoid Non-Uniformity of Flowthe effect, depending on the residence time of the melt in the compression region. Another method of reducing the weld line effect is to use mixing devices in the die such as breaker plates, spreader plates (2) or spiral spreaders.

Gelation and Fusion Characteristics of PVC Resins in Plastisol by Determination of Their Viscoelastity |η*| were recorded as functions of temperature. Two temperature profiles were used: one was 20°C/min. to simulate a process, i.e., a heating rate in an oven, and the other was 5°C/min., a slower heating for a better characterization of gelation behavior.
