PET Special Servo Injection Molding Machine
（YSX120-1200-PET)
YISU PET preform injection molding machines are specially customized servo machines designed exclusively for mass production of PET bottle preforms.
Different from general-purpose injection machines, our PET machines are fully optimized for PET material’s unique melting, viscosity, and molding characteristics, ensuring stable preform quality, high output rate, and long-term continuous production stability.
We provide multiple tonnage options and full custom solutions to match different preform sizes, gram weights, and multi-cavity mold requirements.
Combining digital technology with industrial ecology, we customize the excellent whole technical solutions for you to bring a better electric plasticizing injection molding experience. Excellent quality casts a better future.
Core Advantages of YISU PET Special Injection Machine
PET-Specific Optimized Screw & Barrel System
PET-Specific Optimized Screw & Barrel System
PET material is highly sensitive to temperature and easy to hydrolyze and decompose if plasticization is unstable. YISU custom PET screw and barrel adopt professional compression ratio and anti-decomposition structure. It realizes uniform melting, avoids material yellowing, black spots, and bubble defects, and greatly improves the qualification rate of bottle preforms. The special anti-corrosion and high-temperature resistant design also extends the service life of key wearing parts.
High-Stability Servo Energy-Saving System
Equipped with high-response servo power system, our PET machines provide accurate injection pressure and stable clamping force during long-time continuous molding. Compared with ordinary hydraulic machines, it reduces power consumption significantly, lowers production costs for large-volume preform factories, and maintains consistent injection volume and preform weight for every shot.
Strict Temperature Control for Anti-Hydrolysis Molding
PET preform production requires extremely precise temperature control. YISU PET dedicated machines adopt multi-stage independent temperature control modules, which accurately control the temperature of the feeding section, compression section, and nozzle position. It effectively prevents PET hydrolysis, material degradation, and preform internal stress problems, ensuring clear preform thread, smooth inner and outer walls, and qualified blow-molding performance.
Support High-Cavity & High-Efficiency Production
Our custom PET injection machines are well-adapted to high-cavity preform molds, from small cavity daily samples to large-scale mass production molds. With fast injection speed, stable mold opening and closing, and short cycle time, the machine greatly improves daily output and is very suitable for large-scale bottled packaging factories.
Strong Compatibility & Full Customization
We customize machine parameters according to customers’ actual preform products, including preform gram weight, bottle mouth specification, mold size, and output demand. Whether it is small cosmetic preforms, medium beverage preforms, or large-caliber edible oil bottle preforms, YISU can provide matched professional injection molding solutions.
Low Defect Rate & High Consistency
The whole machine adopts precision hydraulic matching and closed-loop control technology. Each batch of preforms maintains highly uniform weight, wall thickness, and thread precision. It effectively reduces defective products, material waste, and secondary rejection rates, helping customers achieve stable and standardized mass production.
Custom Solution Support
Different PET preform sizes and cavity numbers require different machine configurations. As a professional custom injection molding machine manufacturer, YISU does not provide fixed standard machines only. We configure the most suitable tonnage, injection volume, screw specification, and mold opening stroke according to your products, helping you achieve the best production efficiency and cost performance.
