The Vitro Scientific Production Journey
How raw polymer pellets are transformed into certified, precision-molded packaging containers ready for high-speed filling lines.
Resin Dehumidification
Virgin PET or food-grade rPET flakes enter desiccant drying towers at 160°C to 175°C for 5 hours, reducing moisture content below 50 ppm to prevent polymer chain scission.
Precision Preform Injection
The molten polymer is injected into multi-cavity hot runner molds under high hydraulic pressure, creating preforms with exact neck thread geometry and gate vestige clearance.
Thermal Conditioning
Preforms pass through near-infrared (NIR) heating tunnels with zone-specific temperature profiling to ensure perfect axial and radial stretch behavior during blowing.
Bi-Axial Stretch Blow Molding
Servo-driven stretch rods push downward while clean, oil-free 40-bar compressed air inflates the preform into the chilled water-cooled mold cavity, locking in molecular orientation.
Integrated Quality Inspection
Every molded unit is pneumatically transferred through high-speed multi-spectrum optical vision stations and high-vacuum leak testing cups to verify hermetic sealing.
Robotic Palletizing & Export
Containers are collated, wrapped in dust-proof antistatic liners, boxed in heavy double-wall corrugated cartons, and palletized with automated stretch wrap for sea freight.
