New Hybrid Injection Stretch Blow Molding Equipment Drives Industry Development

According to reports, Nissei ASB Machinery Co., Ltd. globally debuted its new injection stretch blow molding equipment, the ISBM-ASB-70DPH/50E, at K2025. This is a completely upgraded version of the company's best-selling one-step equipment, with all major movements (including injection and preform stretching) electrically driven. The hydraulic system is only used when high clamping forces are required.

I. Advantages of the Machine Upgrade

The new hybrid design minimizes energy consumption, hardware costs, and maintenance costs while improving control precision and production efficiency. Compared to the hydraulic version, drive energy consumption is reduced by approximately 25%, while faster, more precise servo motion shortens cycle time, ensuring smoother and quieter operation. Servo-driven tension rods significantly improve molding consistency, especially when using sensitive resins or complex designs.

II. Impact on Industry Development

This design undoubtedly ushers in a new era for the entire industry. Injection stretch blow molding technology can produce HDPE containers with "perfect bottlenecks, no weld lines, and zero leakage." While conventional bottle shapes are round, this new technology can support special shapes such as non-circular ones, greatly improving the production range and precision of products.

III. Current Status of Dawson Machines

Dawson has been deeply involved in the ISBM industry for over a decade, with customers in many countries. Currently, our main market is in South America and other regions. Our machines can produce bottles up to 1L in size and have three stations: injection molding, blow molding, and demolding. They are suitable for pharmaceutical bottles, cosmetic bottles, jars, ball bearings, etc., and can produce products made from PET, PP, PETG, Tritan, PS, and PC materials.

IV. Our Case Study

We are honored to have meticulously crafted a high-end aromatherapy bottle for a well-known pharmaceutical company in Colombia.. This product is manufactured using a leading one-step injection stretch blow molding (ISBM) process, ensuring uniform bottle wall thickness, crystal clarity, and exceptional dimensional accuracy combined with unparalleled sealing performance. Leveraging the high strength inherent in ISBM technology, this aromatherapy bottle not only boasts a superior aesthetic, perfectly embodying the brand image, but also provides durable and stable protection for its contents, fully meeting the client's stringent requirements for high-quality packaging.

V. Conclusion

Looking back on our development, our ISBm (One-Step Injection Pull-Out Blow Molding) technology has traversed an extraordinary journey, from introduction and assimilation to independent innovation. Today, our ISBm production line has successfully achieved a remarkable integration of high efficiency, precision, and stability. By providing solutions to numerous well-known domestic and international clients (such as Laboratorios Cofarma S. of Colombia), we have proven our ability to produce cutting-edge products with uniform wall thickness, superior quality, and both aesthetic appeal and robustness.

Looking to the future, we will continue to uphold the philosophy of technology leadership, dedicating ourselves to pushing ISBm technology to new heights of intelligence, flexibility, and environmental friendliness.
