Capacity
We have been developed and improved our one step of ISBM machine to make the capacity up to 23000~24000BPH.With the same unit area,our capacity is larger than two step machine!
Save Costs
One-step injection stretch blow molding technology utilizes residual heat from preform injection to blow bottles directly, eliminating storage and reheating processes. This integrated approach removes the need for additional equipment such as separate injection machines, blow machines, preform feeders, conveyors, and welding ring machines, significantly reducing floor space, labor costs, and utility consumption.
While standard bottle mouth inner diameter in the market is 18mm, our technology achieves 16mm, allowing smaller caps and reducing overall bottle costs. Our patented bottle lifting ring integration eliminates welding processes, greatly improving production yield.
Space Saving: No additional equipment needed
Labor Saving: Integrated one-step process
Cost Saving: Smaller mouth design (16mm vs. 18mm standard)
Yield Improvement: Patented lifting ring integration
Quality
Our one-step injection stretch blow molding technology features both preform injection and blowing functions, enabling superior bottle forming with enhanced precision. The patented bottle lifting ring integration eliminates welding reject rates and ensures consistent quality. With significantly lower shrinkage rates and minimal deformation after sterilization, our bottles maintain dimensional stability throughout the entire production and filling process.
Superior Forming: Preform + double blowing function for easier shaping
Zero Welding Reject: Patented lifting ring integration
Dimensional Stability: Low shrinkage, minimal sterilization deformation
Bottle Lifting Ring Integration
Our patented bottle lifting ring integration technology eliminates the need for additional injection machines, molds, and welding processes. This innovation significantly improves production yield while reducing contamination risks – a critical advantage for pharmaceutical packaging. The streamlined process also creates a tidier, cleaner workshop environment, meeting the highest standards of hygiene and operational efficiency.
No Additional Equipment: Eliminates injection machines, molds, and welding
Higher Yield: Improved production efficiency
Reduced Contamination: Minimized pollution risks
Cleaner Workshop: Tidy and hygienic production environment
Regulatory Compliance – The Future is One-Step
The Chinese government has issued regulations restricting the use of two-step infusion bottle blow molding machines, with penalties imposed on pharmaceutical companies that do not comply. This policy shift makes our one-step ISBM technology the ideal solution for pharmaceutical manufacturers seeking to meet regulatory requirements while improving efficiency and product quality. By choosing our one-step injection stretch blow molding machines, you not only stay ahead of regulations but also benefit from higher yield, lower contamination risks, and reduced operational costs.
Regulatory Compliant: Meets government standards for pharmaceutical production
Risk-Free: Avoid penalties associated with two-step equipment
Future-Proof: Position your business for long-term success
