Q
Large Weight Fluctuation of High-Density Polyethylene Injection-Molded Products
Q
Insufficient Impact Strength of High-Density Polyethylene Injection-Molded Products
Q
Roundness Out of Tolerance of High-Density Polyethylene Injection-Molded Products
A
Roundness out of tolerance is caused by non-uniform shrinkage, and needs to be improved from three aspects: cooling symmetry, gate design, and wall thickness uniformity.

Q
Processing Difficulties Caused by Melt Flow Rate Mismatch of High-Density Polyethylene Raw Material
A
MFR mismatch needs to be solved by selecting a suitable grade and adjusting process parameters; the key is to establish an incoming MFR inspection system.
