One Step Injection Stretch Blow Molding Machine HGY250-V4: The ASB-70DPH Compatible Industrial Standard
Engineered by Ever-power | 4-Station High Precision | 300KN Injection Clamping Force
Engineering Overview: Maximizing Legacy Tooling Value
In the specialized world of polymer processing, the debate between upgrading machinery and preserving tooling assets is constant. As a mechanical engineer with two decades dedicated to One Step Blow Molding Machine technology, I have seen too many factories scrap perfectly good molds because they couldn’t find compatible modern machinery. The HGY250-V4 is Ever-power’s answer to this industry-wide challenge. It is a heavy-duty, 4-station ISBM unit designed with a singular strategic advantage: direct compatibility with ASB-70DPH molds.
This machine is not merely a retrofit solution; it is a performance upgrade. Operating on a robust 4-station rotary indexing system (Injection, Temperature Conditioning, Stretch-Blow, Ejection), the HGY250-V4 ensures optimal thermal history for PET and PETG resins. With a massive 300KN Injection Clamping Force and a reinforced 200KN Blowing Clamping Force, it effortlessly handles high-cavitation setups (up to 14 cavities) and heavy-wall containers that lesser machines fail to mold consistently. For manufacturers in the cosmetic and pharmaceutical sectors, this is the most logical path to expanding capacity while leveraging your existing high-value Japanese tooling inventory.

Core Technology: 4-Station ISBM Process Flow
The One Step Injection Blow Molding technology used in the HGY250-V4 is a masterclass in thermal management. By using a rotary table to move the cores between four distinct stations, we ensure the PET retains its Intrinsic Viscosity (IV) for maximum strength and clarity, without the energy loss of reheating.
1. Injection Station
Molten PET is injected into the cavity. The 300KN clamping force ensures no flash on the parting lines, even with high-pressure injection required for thin-wall preforms or complex necks.
2. Conditioning Station
The V4 Advantage: The preform is transferred to a conditioning pot. This station homogenizes the temperature—cooling the skin or heating the core—creating the perfect thermal gradient for stretching.
3. Stretch & Blow
A stretch rod extends the preform axially, followed by high-pressure air expanding it radially. The 200KN Blow Clamping Force ensures the mold remains perfectly closed during high-pressure expansion.
4. Ejection
The finished bottle is stripped from the lip mold and automatically conveyed out. The process is touchless, ensuring hygiene for pharmaceutical applications.
Why Choose the HGY250-V4? Core Advantages
- ✓
ASB-70DPH Compatibility: The platen design, tie-bar spacing, and ejection strokes are engineered to accept existing ASB-70DPH molds. This saves you tens of thousands of dollars in re-tooling costs. - ✓
High-Tonnage Stability: With a 16-ton machine weight and 300KN clamping force, vibration is non-existent, leading to superior bottle reproducibility and longer mold life. - ✓
Energy Dynamics: We use Nano-far-infrared heating rings (10KW) which penetrate the barrel deeper and faster than standard ceramic heaters, saving ~30% on heating costs. - ✓
High Cavitation Capability: Capable of running up to 14 cavities for small vials, drastically increasing output per cycle compared to standard 4-8 cavity machines.

Engineer’s FAQ
Can I use my existing ASB-70DPH molds directly?
Yes, absolutely. The HGY250-V4 is engineered with the same platen layout and mounting points. You can transfer your legacy molds directly to our machine.
What is the max bottle size for this machine?
In a 2-cavity configuration, it can produce bottles up to 2.5 Liters (200mm diameter). In a 14-cavity setup, it is optimized for small vials up to 30ml.
What is the maintenance schedule?
We recommend a hydraulic oil change every 5,000 hours and a daily check of the lubrication points. The auto-lube system handles most moving parts.
