Six basic principles of plastic extrusion

When the melt enters the transition section and the die, shear heating diminishes significantly, because the melt has started to transition from a spiraling, variable-speed flow to a linear, uniform-speed flow when it reaches the transition section. When the melt reaches the mold along the flow path......
