PROBLEMS IN PERFORMANCE OF PLASTIC PARTS

ANALYSIS OF PLASTIC PART FAILURES by RAPRA

High failure cause to low failure cause- in descending order

The predominantly material causes involved in failure were:

The predominating process faults were:

Environmental Stress Cracking,

Excessive moulded-in stresses,

Cyclic Fatigue,

Voiding,

Notch Sensitivity,

Poor weld lines,

Chemical Attack and; Stress Cracking,

Adverse Orientation,

UV Degradation,

Material contamination,

Thermal Degradation,

Longer Residence time in the machine,

Creep,

Wrong material selection or poor part design,

Buckling,

Wrong material selection or poor part design
