（ISBM）One Step Blow Molding Machine HGY650-V4: The Heavy-Duty 4-Station ISBM Solution
Engineered by Ever-power | High-Tonnage Clamping | 4-Station Precision for Large Containers
Engineering Overview: Dominating Large-Scale Production
In the heavy industrial sector of polymer processing, stability under pressure is the only metric that matters. As an engineer with two decades of experience fine-tuning One Step Blow Molding Machine production lines, I present the HGY650-V4. This machine represents the pinnacle of our V4 series, designed specifically for manufacturers requiring massive clamping force and large shot capacities for heavy-wall containers, wide-mouth jars, and high-volume cavitation setups.
The HGY650-V4 operates on a robust 4-station rotary indexing system (Injection, Temperature Conditioning, Stretch-Blow, Ejection). Unlike smaller models, the “650” designation reflects its superior capability to handle substantial projection areas without flashing. It features a reinforced chassis and an advanced hydraulic/servo hybrid system that delivers exceptional locking force. This makes it the ultimate ISBM Machine for producing PC water bottles, large PETG cosmetic jars, and pharmaceutical bulk containers where dimensional accuracy and optical clarity are non-negotiable.

Core Technology: 4-Station ISBM Process Flow
The One Step Injection Blow Molding technology used in the HGY650-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 High 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 300KN 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 HGY650-V4? Core Advantages
- ✓
Heavy Duty Construction: Designed for large molds and high injection pressures, this machine eliminates “breathing” of the mold during injection, ensuring precise part weights. - ✓
High Cavitation for Mass Production: Capable of running up to 16 cavities for small vials, or 4 cavities for massive 1.5L jars, giving you flexibility across product lines. - ✓
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. - ✓
Stability: With a substantial machine weight and robust tie-bars, vibration is minimized, leading to longer mold life and reduced maintenance.
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 |
| Space Requirement | Compact (One machine) | Large (Requires Injection unit + Blow unit + Storage) |
| Hygiene Level | Medical/Food Grade (Touchless) | Standard (Exposed to open air storage) |

Engineer’s FAQ
What is the benefit of the high clamping force?
The 650KN equivalent injection force prevents the mold from “breathing” or opening slightly during high-pressure injection, which is critical for maintaining precise neck dimensions and preventing flash on the parting line.
Can I run Tritan material on this machine?
Yes, the plasticizing unit is designed to handle high-temperature engineering plastics like Tritan, PC, and PPSU effectively.
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.
