Uneven Wall Thickness of LDPE Blow Molded Bottles

The wall thickness program is the core.

Blow Molding LDPE; '2079851475616104457; uneven wall thickness; parison program; drop

Poor Surface Gloss of LDPE Injection Molded Products

Soft material gloss relies on mold temperature and polishing.

Injection Molding LDPE; '2079851475616104452; gloss; mold temperature; polishing

LDPE Film Slip Agent Blooming

Blooming = excessive additive precipitation.

Extrusion & Post LDPE; film; blooming; slip agent; precipitation

Fast Pressure Differential Rise of LDPE Extrusion Filter Screen

Fast pressure differential rise = dual sources of gel + impurities.

Extrusion & Post LDPE; extrusion; filter screen; gel; regrind

LDPE Film Winding Edge Wandering

Edge wandering = joint action of tension + thin-thick edges.

Extrusion & Post LDPE; film; winding; edge wandering; tension

LDPE Injection Molded Product Deformation - Ejection Type

Soft material ejection needs 'fully cooled + large area'.

Injection Molding LDPE; '2079851475616104452; ejection deformation; cooling; ejection

Rough Surface of LDPE Blow Molded Bottles

2079851475616104457 surface = parison temperature + blow air energy.

Blow Molding LDPE; '2079851475616104457; rough surface; blow air pressure; mold temperature

Burnt Material at LDPE Extrusion Die Head

Burnt material = dead-spot stagnation degradation.

Extrusion & Post LDPE; extrusion; burnt material; die head dead spot; degradation

Stress Cracking of LDPE Injection Molded Products

Soft materials also fear long-term overstress.

Injection Molding LDPE; stress cracking; interference; creep

Unstable Frost Line in LDPE Blown Film

The frost line is the thermometer of the blown film process.

Extrusion & Post LDPE; blown film; frost line; air ring; crystallization
