We are more than a supplier; we are an extension of your product packaging team. In a market where first impressions determine purchases, the integrity, aesthetics, and functionality of packaging are paramount. We are dedicated to merging precision engineering with innovative materials to provide packaging solutions starting from the preform for every drop of oil, sip of beverage, and liquid product you create. Choosing us means choosing a future of reliability, precision, and limitless customization potential.
In-Depth Analysis: Core 36mm Standard Neck Preform
As a widely adopted industry standard, our 36mm preform is synonymous with quality and reliability.
Thread Design: Optimized lead and profile ensure stress-free, leak-proof sealing with standard 36mm caps (e.g., PCO 1881).
Raw Material: High-quality, food-grade PET resin with stable IV (Intrinsic Viscosity). Options include standard grade, high-barrier grade (for enhanced CO2/O2 barrier), or customized rPET content for sustainability goals.
Excellent Mechanical Strength: High tensile strength for superior pressure and impact resistance after blow molding.
Chemical Stability: Inert to water, oils, alcohols, and most mild chemicals.
Manufactured in a 100,000-class cleanroom using fully servo-electric injection molding machines. Each cavity features independent hot runner temperature control and cavity pressure sensors, ensuring weight variation of less than ±0.15g and wall thickness uniformity over 98%, providing optimal conditions for high-speed blow molding.

Why Choose Us? Five Core Advantages
Exceptional Dimensional Stability & Consistency
We understand that consistent preforms are the foundation of efficient blow molding lines. Through closed-loop process control, online SPC (Statistical Process Control) checks every 2 hours, and stringent final inspection (AQL 0.65 sampling), we guarantee batch-to-batch uniformity in dimensions, weight, and performance, minimizing your production line downtime.
Deep Customization Capability for Brand Differentiation
Neck Differentiation: Integrated TE bands, freshness seal grooves, anti-slip threads.
Pre-form Design: Optimized wall thickness distribution to pre-strengthen areas for special bottle shapes (square, oval, grip designs).
Surface Treatment: Plasma treatment available for enhanced printing/labeling adhesion.
Technical Collaboration & End-to-End Support
Our experienced engineering team provides full-cycle support: feasibility analysis for bottle design, collaborative mold development, blow molding parameter recommendations, and on-site trial assistance. We solve packaging challenges with you, not just sell to you.
Lightweighting design services to reduce plastic usage without compromising performance.
Agile Supply Chain & Global Service
With multiple modern production bases, we can flexibly arrange production and storage based on your regional needs. Rapid response for trial orders, guaranteed on-time delivery for bulk orders. Wherever you are, we provide timely professional service and logistics support.
Challenge: Oxidation prevention, leakage-proof, maintaining clarity.
Our Solution: 36mm/32mm are preferred. High-purity PET is recommended to prevent odor transfer. Precision sealing, combined with oxygen-barrier caps, extends shelf life.
From Concept to Product: Our Collaboration Process
You provide: product concept, volume, content properties, filling line info, brand visuals (color), expected annual usage.
Our engineering team conducts feasibility analysis, providing preform specifications, 2D drawings, 3D renderings, material selection, and a detailed quotation.
Mold Development & Sample Approval:
Molds are manufactured using high-precision CNC machining centers.
First samples provided within 5-10 working days for dimensional checks, lab tests (seal, drop, stack), and blow molding trials.
End-to-end quality control from raw material to finished goods during production, with a Certificate of Analysis (COA) provided per batch.
Professional packaging and logistics ensure safe arrival. After-sales technical support guarantees optimal preform performance on your line.
