Prefrom/Cap Injection Machine
High-Efficiency PET Preform & Cap Injection Molding Machines
The Smart Core of PET Bottle Production
Unlock superior bottle quality at the source with our next-generation PET preform injection molding systems. Designed for high output and exceptional consistency, these machines deliver stable, repeatable precision to ensure every preform meets the strictest quality standards.
Powered by a high-performance servo drive system, the HD Series provides 50% greater driving force, up to 30% faster cycle times, and 30% lower energy consumption. Seamlessly integrated into blow molding operations, it forms a reliable, high-volume foundation from preform to cap.
Precision Preforms, Better Bottles
The quality of your final container is determined at the preform stage. An inefficient or inconsistent injection process creates downstream bottlenecks, material waste, and quality defects that compromise your entire production line.
The High Cost of Inefficient Preform Production
| Production Aspect | With Our HD Series Injection Machine | With Standard/Outdated Equipment | Impact on Your Business |
|---|---|---|---|
| Energy Consumption | 30% reduction in electricity via advanced servo-hydraulic system. Energy is used on-demand, not wasted. | High constant energy draw from traditional hydraulic systems, regardless of machine activity. | Significantly lower operational costs, improving margin per preform and reducing carbon footprint. |
| Cycle Speed & Output | 30% faster cycle times due to superior servo drive force and precision. Maximizes shots per hour. | Slower, inconsistent cycles limit maximum output and create a bottleneck for your blowing lines. | Higher production capacity from the same footprint. Meets demand without adding extra machines. |
| Preform Quality & Consistency | Special PET-feeding screw ensures perfect plastification, uniform melt temperature, and superior material properties. | Risk of uneven heating, degradation, or weak spots, leading to blowing failures and bottle defects. | Dramatically lower scrap rates (<0.5%). Produces strong, consistent preforms for optimal bottle clarity and strength. |
| System Stability & Uptime | Robust construction with precision components designed for 24/7 operation. Minimal maintenance intervals. | Frequent breakdowns, temperature fluctuations, and alignment issues cause unplanned downtime. | Predictable, continuous production. Protects your supply commitments and maximizes asset utilization. |
| Total Cost of Ownership | Higher initial efficiency yields rapid ROI through energy savings, higher output, and reduced waste. | Lower upfront cost offset by perpetually high energy bills, maintenance costs, and quality penalties. | Superior long-term investment. Our machines are engineered for profitability over a decade or more. |
Built for High-Performance Production
Our systems are designed to work in harmony—depalletizers feed your line, and palletizers close it—creating a continuous, automated loop.
