SHEAR RATE/ SHEAR STRESS

SHEAR STRESS

SHEAR RATE

Simulate the shear changes of the plastic in the die

Too low shear stress will cause plastic degradation and channeling effect; enough shear stress will help polymer scrape the inner wall surface to achieve cleaning effect; if the critical shear stress is exceeded, there will be shark skin on product surface.
