The production of high-end lotion pump dispensers demands absolute precision, flawless optical clarity, and robust structural integrity. At Ever Power, our advanced دستگاه قالب گیری بادی کششی تزریقی تک مرحله ای technology delivers exactly that. By integrating the entire manufacturing process into a single, seamless operation, we help manufacturers eliminate intermediate steps, drastically reduce overhead, and maximize their Return on Investment (ROI).
What is One-Step Injection Stretch Blow Molding (ISBM)?
One-step ISBM is a highly efficient plastic container forming process ideal for manufacturing high-precision hollow products. It is widely used for creating premium cosmetics bottles, baby bottles, water cups, and pharmaceutical packaging from materials like PET, PETG, PP, PC, Tritan, PS, ABS, and PLA. The core characteristic of this technology is that the three main steps—injection, stretching, and blow molding—are completed continuously within the same equipment. This eliminates the need to cool, store, and reheat preforms, significantly boosting production efficiency and ensuring absolute product stability.
جریان فرآیند سادهشده
Our integrated systems execute a flawless sequence to transform raw resin into a finished, premium dispenser:
- تزریق: Molten plastic is precisely injected into the cavity to form the preform, defining the exact neck finish for lotion pumps.
- Preform Tail Cutting / Heat Preservation: The preform’s temperature is carefully conditioned and equalized, utilizing its latent heat for the next step.
- قالبگیری بادی کششی: A stretch rod axially extends the preform while high-pressure air radially blows it against the mold walls, ensuring perfect molecular orientation.
- بیرون بردن بطری: The finished, cooled product is automatically ejected, ready for immediate packaging or filling.

Crucial Integration: Matching Blow Molding Air Compressors
A critical, yet sometimes overlooked, factor in achieving flawless high-end lotion pump dispensers is the quality of the compressed air used during the final forming phase. To ensure the highest production standards, Ever Power also provides perfectly matched blow molding air compressors.
Why is this essential for our one-step machines? In the stretch blow molding stage, high-pressure air directly shapes the hot plastic against the cavity walls. If the air pressure fluctuates, it can cause inconsistent wall thickness or structural weaknesses. Furthermore, for cosmetic and personal care packaging, the air must be absolutely clean and oil-free to prevent any internal contamination or clouding of the clear plastics. Our dedicated oil-free screw air compressors deliver a consistent, highly stable, and pure air supply. This ensures the machine performs at its absolute peak, minimizing defect rates and maximizing your ROI. By sourcing both the molding machine and the compressor from us, you guarantee a unified, highly reliable production line.

سوالات متداول (FAQ)
1. Why is a one-step machine better than a two-step for high-end lotion bottles?
A one-step process handles the preform while it retains its initial injection heat, preventing surface scratches that occur during storage and transport in a two-step process. This guarantees the highest level of optical clarity and a pristine finish required for luxury cosmetics.
2. Can we manufacture custom bottle shapes and asymmetrical designs?
Yes. The independent temperature control zones in the heating phase allow us to selectively heat specific areas of the preform. This makes it entirely possible to stretch and blow complex, asymmetrical, or uniquely customized bottle shapes with even wall distribution.
3. How long does a typical mold changeover take?
Our machines feature a rapid mold change technology designed to minimize downtime. An experienced operating team can typically complete a full mold changeover in 60 minutes or less.
4. What maintenance is required for the patented injection screw?
The patented screw is built for durability and high-volume output. Routine maintenance involves standard purging when switching materials or colors, and periodic inspection of the heating bands and barrel alignment. Our control system also features diagnostic alerts to inform operators of any required preventative maintenance.
5. Does the machine support thick-walled PETG applications?
Absolutely. For very thick-walled cosmetic jars and bottles, we highly recommend our 4-station machine configuration. The extra conditioning station ensures the thicker preform is heated uniformly to the core before stretching, preventing stress whitening and ensuring glass-like transparency.
