Manufacturing Process
From raw material inspection to final quality control -- a transparent look at how we deliver precision PET preforms at scale.
Our PET Preform
Production Process
Every PET preform we produce goes through a rigorous, precision-controlled manufacturing process -- ensuring consistent quality, dimensional accuracy, and compliance with global standards.
Raw Material Inspection
Virgin PET resin is rigorously tested for intrinsic viscosity, moisture content, and purity -- meeting RoHS & REACH standards before entering production.
Drying & Pre-Treatment
PET pellets are dried at precise temperatures (160-180°C) for 4-6 hours, reducing moisture to below 50 ppm to prevent hydrolysis during molding.
Precision Injection Molding
60+ automated injection molding machines with ±0.1mm precision. Controlled melt temperature, injection speed, and cooling cycles ensure consistent wall thickness.
Quality Control & Inspection
100% factory inspection on every unit -- weight, dimensions, clarity, and neck thread accuracy. ISO 9001 AQL sampling applied to every production batch.
Custom Coloring & Branding
Masterbatch colorants are precisely dosed and blended. Custom colors matched to Pantone standards, along with OEM/ODM mold design, give your brand a distinct identity.
Packaging & Global Export
Finished preforms are packed in anti-static, moisture-proof bags and cartons. Full export documentation, COA, and compliance certificates shipped with every order.
