Q
Bubbles/pores on the surface of low density polyethylene extruded products
Q
Melt flow rate mismatch of raw material for low density polyethylene extrusion
A
MFR mismatch needs to be solved by selecting appropriate grades and adjusting temperature parameters.

Q
Insufficient rigidity of low density polyethylene injection products
Q
Core shift of low density polyethylene injection mold causing uneven wall thickness
A
Core shift is caused by insufficient rigidity or uneven force; it needs to be solved from core design, gate layout, and injection parameters.
