One Step Injection Stretch Blow Molding Machine HGY250-V4-B: High-Output Double-Row 4-Station ISBM Technology
Engineered by Ever-power | Double-Bank Cavitation (Up to 28 Cavities) | 680g Shot Capacity
Engineering Overview: The “Double-Row” Productivity Multiplier
In the high-volume production of small-format containers—such as pharmaceutical vials, hotel amenities, and mini-liquor bottles—cycle time is only half the battle. The real victory lies in cavitation density. As an engineer who has spent two decades optimizing One Step Blow Molding Machine layouts, I present the HGY250-V4-B. This is not just a standard machine; it is a “Double-Row” (Double Bank) powerhouse designed to effectively double your output per footprint.
The HGY250-V4-B operates on a 4-station rotary indexing system but utilizes a specialized mold layout that accommodates two rows of cavities. This allows for an astounding 16 to 28 cavities for bottles under 100ml, while maintaining a robust 300KN Injection Clamping Force. By injecting a massive theoretical shot weight of 680g, this machine is specifically engineered for manufacturers who need to produce millions of units of high-quality, flash-free PET or PETG containers annually without investing in multiple standard machines. It is the ultimate high-efficiency solution in the ISBM Machine sector.

Core Technology: 4-Station Double-Row ISBM Process
The One Step PET Bottle Machine maximizes quality by controlling the polymer’s thermal history. The HGY250-V4-B employs a unique 4-station process that handles two rows of bottles simultaneously, doubling throughput without sacrificing precision.
1. Double-Row Injection
Molten PET is injected into a double-row cavity plate. The 300KN clamping force and 680g shot capacity ensure equal pressure across all 28 cavities (in max configuration), preventing short shots.
2. Uniform Conditioning
The double row of preforms is transferred to the conditioning station. Advanced thermal regulation ensures that inner and outer rows receive identical heat profiles for consistent stretching.
3. Precision Stretch & Blow
Stretch rods extend the preforms axially while 2.0-3.5 Mpa air expands them. The 250KN Blow Clamping Force ensures zero parting lines, even when molding 28 bottles at once.
4. Mass Ejection
Finished bottles are stripped from the lip molds. The touchless process makes this machine ideal for high-volume pharmaceutical and food-grade applications.
Why Choose the HGY250-V4-B? Core Advantages
- ✓
Extreme Cavitation (Double Bank): While most machines stop at 12 or 16 cavities, the V4-B pushes to 28 cavities for small diameter products (25mm), fundamentally changing the economics of vial production. - ✓
High Shot Weight (680g): This allows for heavy-wall, high-quality manufacturing even in high-cavity setups. You don’t have to sacrifice bottle weight/quality for quantity. - ✓
Energy Dynamics: Despite the high output, the servo-driven system ensures that energy is only consumed during movement, reducing the cost-per-bottle significantly compared to running two smaller machines. - ✓
Space Efficiency: You get double the production output of a standard machine in a footprint of just 5.2m x 2.5m.
Strategic Analysis: One-Step vs. Two-Step Systems
| Comparison Dimension | Ever-power One-Step ISBM | Traditional Two-Step (Reheat) |
|---|---|---|
| Process Flow | Resin -> Bottle (Integrated) | Resin -> Preform -> Cool -> Reheat -> Bottle |
| Energy Efficiency | High (Uses latent injection heat) | Low (Wastes energy reheating preforms) |
| Surface Quality | Flawless (No scuffing/scratches) | Risk of transport scratches on preforms |
| Applicable Materials | PET, PETG, PC, Tritan, PPSU, PP | Mostly limited to PET/PP |
| Small Bottle Efficiency | Excellent (Double row handles small preforms well) | Poor (Reheating small preforms is unstable) |
| Hygiene Level | Medical/Food Grade (Touchless) | Standard (Exposed to open air storage) |

Engineer’s FAQ
What is the benefit of a “Double Row” or “Double Bank” machine?
It allows you to fit more cavities into the mold by staggering them or placing them in two parallel lines. This is the only way to achieve high cavitation (20+) for small bottles on a machine of this size.
Can I run large bottles on this machine too?
Yes, you can run larger bottles (up to 1L) by using a mold with fewer cavities (e.g., 8 cavities). However, the machine is optimized for high-volume small containers.
Does the double row setup affect temperature conditioning?
No, our conditioning station is specifically designed with multi-zone heating/cooling to ensure that the inner row and outer row of preforms receive the exact same thermal treatment.
