Product Description
Our Preform Injection Moulding Machine integrates advanced injection technology, precision control systems, and durable structural design to transform raw materials (such as PET, PP, and HDPE) into high-quality preforms with consistent dimensions, smooth surfaces, and reliable performance. It is the key link in the plastic packaging supply chain, bridging raw material processing and final product blow molding.
Our PET preform injection machine stands out for its high efficiency, energy savings, and versatility. It addresses the pain points of traditional equipment—such as low production speed, unstable product quality, and high energy consumption—by adopting innovative technologies like servo-driven injection systems and multi-cavity mould compatibility. Whether for small-batch custom production or large-scale mass manufacturing, our machine delivers consistent output, reduces material waste, and lowers operational costs, creating long-term value for packaging manufacturers, beverage companies, and cosmetic brands.
Equipped with a high-precision injection unit and closed-loop control system, our precision preform injector ensures that each preform has uniform wall thickness, accurate neck dimensions, and no defects (such as bubbles or warping). The mould clamping force (ranging from 50 to 500 tons) is adjustable to match different preform sizes, while the precise temperature control system maintains stable melting of raw materials—guaranteeing that preforms meet strict industry standards and are compatible with subsequent blow molding processes.
Our high-speed preform moulding machine achieves an injection cycle time as short as 8-15 seconds, depending on preform specifications and cavity count. The servo motor-driven injection system provides fast response and stable power output, while the automatic mould opening/closing mechanism reduces downtime between cycles. For multi-cavity configurations (up to 72 cavities), the machine can produce thousands of preforms per hour, significantly improving production capacity and meeting tight delivery deadlines.
Adopting an energy-efficient servo hydraulic system, our energy-saving preform injection machine consumes 30-40% less electricity compared to traditional hydraulic machines. The intelligent power management system adjusts energy output based on production load, avoiding unnecessary waste. Additionally, the optimized heating system uses ceramic heaters with high thermal efficiency, reducing heat loss and further cutting energy costs. Over the long term, these design features translate to substantial savings in operational expenses.
Our machine supports multi-cavity preform moulding machine configurations (from 4 to 72 cavities), allowing manufacturers to switch between different preform sizes and shapes by replacing moulds. The quick-mould change system enables mould replacement in less than 30 minutes, minimizing production interruptions. Whether producing small preforms for cosmetic bottles (10ml) or large preforms for 5-gallon water bottles, our machine adapts easily to diverse production needs.
The automatic preform injection system is equipped with a user-friendly touchscreen HMI (Human-Machine Interface) that allows operators to set parameters (such as injection speed, temperature, and cycle time), monitor production status, and troubleshoot issues in real time. The system also supports data logging and remote monitoring, enabling managers to track production efficiency, material consumption, and machine performance from anywhere. With minimal training, operators can master the machine, reducing labor costs and human errors.
Single-Cavity Preform Injection Machines: Ideal for small-batch production, custom preforms, or prototype development. They offer high flexibility and low mould costs, suitable for startups or manufacturers with diverse product lines.
Multi-Cavity Preform Injection Machines: Designed for large-scale mass production. With 16-72 cavities, they deliver high output and low unit costs, perfect for beverage companies, bottled water brands, and large packaging manufacturers.
Standard Preform Injection Machines: Meet general industry requirements, supporting common preform sizes (10ml-5L) and materials (PET, PP). They are ready for immediate delivery and easy to maintain.
Customized Preform Injection Machines: Tailored to specific customer needs, such as special preform shapes, unique material compatibility (e.g., biodegradable plastics), or integration with existing production lines. Our engineering team works closely with customers to design personalized solutions.
The primary application of our plastic preform manufacturing equipment is producing preforms for carbonated drinks, mineral water, juice, and tea bottles. PET preforms made by our machine have excellent transparency, impact resistance, and barrier properties, ensuring the freshness and safety of beverages.
Our machine manufactures preforms for skincare bottles, shampoo bottles, and perfume vials. The precision moulding ensures that preforms have smooth surfaces and accurate dimensions, meeting the aesthetic and functional requirements of cosmetic brands.
For pharmaceutical containers (such as medicine bottles and syringe barrels), our machine produces preforms with high hygiene standards and strict dimensional accuracy. The materials used are food-grade and pharmaceutical-grade, complying with FDA and EU regulations.
Preforms for food containers (such as edible oil bottles, sauce jars, and snack packaging) are another key application. Our machine ensures that preforms are resistant to oil, heat, and corrosion, preserving the quality of food products.

We adhere to strict quality control standards throughout the production process of our reliable preform moulding solution. All key components (such as servo motors, hydraulic pumps, and control systems) are sourced from renowned brands (e.g., Siemens, Bosch Rexroth). Each machine undergoes a 72-hour continuous operation test before delivery to ensure stable performance. We also hold ISO 9001 certification and comply with CE, SGS, and other international standards, guaranteeing product quality and safety.
Our after-sales team consists of experienced engineers who provide 24/7 technical support via phone, email, or video call. We offer on-site installation, commissioning, and training services to ensure that customers can operate the machine smoothly. Additionally, we provide a comprehensive spare parts supply system, with common parts available for immediate delivery to minimize downtime.
We offer a 1-year warranty on the entire machine (excluding wearing parts) and a 2-year warranty on key components (such as servo motors and control systems). Our team also provides regular maintenance reminders and on-site maintenance services to extend the machine's service life. Customers can also purchase extended warranty plans for added peace of mind.
Our machine supports a wide range of thermoplastics, including PET (the most common for beverage bottles), PP (for food containers and cosmetic bottles), HDPE (for chemical containers), PS (for pharmaceutical packaging), and biodegradable plastics (such as PLA). We can also customize the machine to process special materials based on customer needs.
Our machine is available in cavity counts from 4 to 72. The optimal cavity count depends on your preform size (smaller preforms can use more cavities) and production volume. For example, a 32-cavity machine is suitable for medium-scale production of 500ml beverage bottle preforms, while a 72-cavity machine is ideal for large-scale production of 330ml carbonated drink preforms.
The production speed varies by cavity count and preform specifications. A 16-cavity machine can produce approximately 1,200-1,500 preforms per hour, while a 72-cavity machine can reach 4,000-5,000 preforms per hour. The injection cycle time is as short as 8 seconds for small preforms, ensuring high efficiency.
