How the Best Plants Run
Parison Control (Axial + Radial)
Direct lever for weight reduction and wall‑thickness uniformity; 64–400‑point controllers and flexible die radial systems are mainstream. Expect 5–10% material savings on many parts after tuning.
Air‑Management (PET)
High‑pressure air is expensive; modern air‑recovery and staging cut air cost substantially (vendor solutions from the major blow‑molding OEMs).
Cooling Uniformity
Copper‑alloy inserts or conformal cooling in tough zones; prevents base‑cracks (PET) and speeds cycles.
Preventive Maintenance
Periodic screw/barrel wear audits (ID/OD clearances), filter/screen checks, vent cleaning, pinch‑edge resurfacing; wear tracking prevents dim weight creep and instability.
Leak & Vision Testing
In‑line 100% testing to contain defects.
