Key ideas in PET Injection Stretch Blow Molding
- Excessive gate vestige height creates a physical pivot point that deflects the stretch rod tip
- Uniform base thickness in ISBM relies on the rod pinning the preform center perfectly against the blow mold base
- Mechanical trimming or gate cooling adjustments are required to minimize the nub height
- High shear rates during the pack phase generate localized thermal energy in the gate area
- Crystallinity occurs when the polymer stays above its glass transition temperature long enough for molecules to organize
- The balance between cooling circuit efficiency and shear heat determines the 'clear' window of the gate
- The relationship between gate vestige height and stretch rod stability
- The cause of gate crystallinity during the pack phase
- Manifold pressure balance ensures equal melt density reaches each gate
- Individual nozzle tip temperature adjustments are secondary to the primary pressure drop across the manifold
- Weight variation in ISBM is a symptom of uneven filling or packing pressures across the mold face
- The geometry of the gate-to-body transition dictates the 'natural' stretch ratio of the material
- Material in the transition zone must be conditioned to flow predictably before radial expansion begins
- The gate area is the last to cool and the first to be influenced by the stretch rod
- Identifying the primary lever for cavity-to-cavity weight consistency
- The influence of gate-to-body transition on material distribution
