One Step Blow Molding Machine HGY50-V3-EV (3-Station) | Precision ISBM Technology
Core Technology Speed Read
The HGY50-V3-EV is a state-of-the-art One Step Injection Stretch Blow Molding Machine designed for high-precision manufacturing. Operating on a fully electric servo platform, this 3-station unit integrates injection, stretching, and blowing into a seamless continuous process. It is engineered to process a wide versatility of materials including PET, PETG, and PC, making it the ideal solution for premium cosmetic and pharmaceutical packaging. With a compact footprint of just 3.8m x 1.2m, it delivers industrial-grade performance while saving valuable factory floor space.

HGY50-V3-EV Overview: The Efficiency Revolution
The HGY50-V3-EV redefines the standards of the One Step PET Bottle Machine market. By adopting a “One Step” methodology, the machine utilizes the residual heat from the injection phase to perform the stretch blow molding immediately. This eliminates the need for reheating preforms, which directly results in an energy consumption reduction of approximately 40% compared to traditional two-step systems.
Key Advantages at a Glance
- Full Servo Precision: Equipped with 5 sets of servo systems (Inovance/Weichi), ensuring injection and clamping accuracy.
- Surface Perfection: The one-step process prevents preform scuffing, ensuring high transparency and barrier properties for the final bottle.
- High Efficiency: Complete automation reduces human error and labor costs while maximizing material utilization.

Why Choose Our HGY50-V3-EV?
- High Material Utilization: Less waste material, environmental protection, and low cost.
- Superior Physical Properties: Stretching makes the material molecules orient, which significantly improves compression resistance, barrier properties, and transparency.
- High Precision: Full process automation control reduces human error, suitable for mass production.

Technology Face-off: One-Step vs. Two-Step
Understanding the difference between One Step Injection Blow Molding and the Two-Step method is crucial for calculating ROI.
| Comparison Dimension | Ever-power One-Step ISBM | Traditional Two-Step Method |
|---|---|---|
| Process Continuity | Continuous (Resin to Bottle) | Discontinuous (Preform Storage Required) |
| Energy Efficiency | High (Saves ~40%) | Lower (Requires Re-heating Preforms) |
| Surface Quality | Flawless (No Scratches) | Risk of Scuffing during Transport |
| Machine Footprint | Compact (One Machine) | Large (Injection + Reheat Blower) |
| Hygiene Level | High (No Human Contact) | Risk of Contamination during Storage |
