Yongjiang PET Preform Injection Machine: A Comprehensive Supplier Analysis for Global Buyers

Yongjiang PET Preform Injection Machine: In-Depth Supplier Analysis for Global Buyers

The global PET preform machines market is estimated at USD 9.9 billion in 2025 and is projected to reach USD 17.3 billion by 2035, driven by demand from the beverage, food packaging, and personal care industries. Injection molding technology holds a dominant 66.4% share of the market, and Asia Pacific accounts for 41.2% of regional revenue, with China as the leading manufacturing hub. Buyers seeking reliable, cost-effective PET preform injection machines often turn to established Chinese manufacturers. Ningbo Yong Jiang Machine Co., Ltd. (Yongjiang) is one such supplier with a track record spanning over 35 years.

Problem Definition: Sourcing a Dependable PET Preform Injection Machine

PET preforms are the intermediate product for blow-molded bottles used in mineral water, carbonated soft drinks (CSD), edible oil, and other packaging applications. A high-quality PET preform injection machine must deliver consistent wall thickness, short cycle times, and low energy consumption while supporting multi‑cavity hot runner molds for 24/7 production. Global buyers need a supplier that combines technical expertise, manufacturing scale, and after-sales support. Yongjiang addresses these requirements with its YJPT series of high-speed PET preform injection machines.

Industry Background

According to Future Market Insights (FMI), the PET preform machines market is expected to grow at a robust CAGR, with injection molding being the dominant technology (66.4% in 2025). The Asia Pacific region holds the largest market share at 41.2%, driven by China's vast production base. While high‑end systems from Husky Technologies control an estimated 55–60% of the global high‑output segment, the mid‑range and value segments are served by a number of capable Chinese manufacturers. Yongjiang, established in 1985, operates a 130,000 m² factory with 200 employees and an annual output of 2,000 units. Approximately 59% of its products are exported, with major markets including the USA, Canada, and Thailand.

Detailed Solution: Yongjiang’s PET Preform Injection Machine Series

Yongjiang specializes in manufacturing injection molding machines, with its main products being PET preform injection molding machines and PVC fitting machines. The company’s YJPT series is purpose‑built for PET preform manufacturing and includes four key models:

• YJPT-260 – 260‑ton clamping force, 72 mm screw, 1,400 g shot weight, 42 kW motor, 35 kW heating, 9 ton weight. Made of QT500‑A7. Ideal for small‑ to medium‑cavity preform production (e.g., 32‑cavity molds).
• YJPT-318 – 318‑ton clamping force, 77 mm screw, 1,900 g shot weight, 80 kW motor, 65 kW heating, 13 ton weight. Equipped with a high‑speed preform mold. Suitable for 48‑cavity production.
• YJPT-360 – 360‑ton clamping force, 95 mm screw, 3,450 g shot weight, 80 kW motor, 65 kW heating, 16 ton weight. Made of QT500‑A7 steel. Capable of running 72‑cavity hot runner molds.
• YJHB-400 – 400‑ton clamping force, 95 mm screw, 3,450 g shot weight, 80 kW motor, 65 kW heating, 16 ton weight. Constructed from QT500‑A7 steel. Designed for high‑output 72‑ to 96‑cavity preform production.

Step‑by‑Step Breakdown: How Yongjiang Machines Deliver Consistent Preforms

1. Raw material preparation: PET pellets must be dried to a moisture content below 0.02% using a hopper dryer to prevent hydrolysis and silver streaks.
2. Injection molding: The machine melts the dried PET and injects it into a multi‑cavity hot runner mold. Yongjiang’s machines are designed for 380 V/400 V 50 Hz three‑phase power with voltage fluctuation within ±10%.
3. Cooling & ejection: The preforms are cooled in the mold and then ejected. The machine is compatible with automated cooling robots for reduced cycle times.
4. Post‑processing: Preforms are collected and transferred to blow molding machines. Yongjiang’s stable injection and low‑energy servo systems support 24‑hour continuous operation.

Supporting equipment includes a PET preform mold, hopper dryer, air compressor, and water chiller. The machine complies with EU CE machinery safety standards and operates in a workshop with ISO Class 8 (100,000‑class) cleanliness for food‑grade production.

Use Cases Across Industries

• Mineral water bottles: YJPT-260/318 with 32–48 cavities produce standard 10–20 g preforms.
• Carbonated soft drinks (CSD): YJPT-360/400 with 72 cavities handle thicker wall preforms (25–30 g) required for carbonation pressure.
• Oil bottles: Heavier 30–40 g preforms are efficiently produced on the YJHB-400.
• Cosmetic containers: Small‑shot‑weight preforms for caps and small bottles run on the YJPT-260.

These applications are common in markets such as Spain and Algeria, where Yongjiang machines are already deployed.
