HGY50-V3 Injection Stretch Blow Moulding Machine

HGY50-V3

3-Station Injection Stretch Blow Moulding Machine — 40 mm Screw · 188 g Injection · 160 MPa · 70 kN Blow Clamp

1–6 Cavities · Max 2.5 L · 3,000 kg · 2,500×1,100×2,450 mm · ASB-12M Compatible · Korea Ever-Power

The HGY50-V3 is Korea Ever-Power's 3-station hydraulic injection stretch blow moulding machine — a compact, versatile ISBM platform that integrates preform injection, temperature conditioning, and stretch-blow in a single rotary machine. Supporting 1 to 6 cavities and container volumes from 100 ml to 2.5 litres, the HGY50-V3 serves cosmetic, pharmaceutical, beverage, and baby product manufacturing applications where one-step ISBM quality — flawless surface, biaxial molecular orientation, precise neck finish — is required at a production scale suited to small and mid-size operations.

Unlike two-step reheat blow moulding, the HGY50-V3 blows from residual injection heat — preforms are never stored, never scratched, never contaminated. The result is bottles with wall-thickness variation under 0.05 mm, superior clarity in PET, PETG, PC, and Tritan, and neck finish accuracy suited to pharmaceutical and premium cosmetic applications. At 2,500×1,100×2,450 mm and 3,000 kg, the machine installs in standard production halls without structural modification. Compatible with ASB-12M moulds.

Container formats producible on the HGY50-V3 — cosmetic, pharmaceutical, baby, beverage, and specialty PET/PETG/PC/Tritan bottles.

▶ HGY50-V3 vs HGY50-V3-EV — Hydraulic or Fully Electric?

Step 1 — Injection

PET, PETG, PC, or Tritan resin is plasticised and injected around the core pin to form the preform. Temperature control ±1°C ensures consistent wall thickness from the first shot. The 40 mm screw delivers 188 g theoretical injection capacity.

Step 2 — Conditioning

The preform rotates to the conditioning station. Excess tail is cut; the body is temperature-conditioned to the optimal stretch zone (105–115°C for PET) while the neck thread remains cool and dimensionally stable.

Step 3 — Stretch-Blow

The stretch rod elongates the preform axially; high-pressure air (2.0–3.5 MPa) expands it radially against the cooled mould. 70 kN blowing clamping force and 50+50 mm mould stroke deliver precise biaxial orientation and consistent wall distribution.

Step 4 — Ejection

The finished bottle is removed at the take-out station (170 mm stroke). Cycle time is typically 12–18 seconds per shot depending on cavity count and container volume. The three stations rotate continuously, keeping all stations active simultaneously.

What is the difference between the HGY50-V3 and the HGY50-V3-EV?

The HGY50-V3 uses a hydraulic drive system; the HGY50-V3-EV is fully electric. Both machines share the same 3-station rotary ISBM platform, the same container capability (1–6 cavities, up to 2.5 L), and are compatible with ASB-12M moulds. The EV variant delivers 40% lower energy consumption, higher injection pressure (210 MPa vs 160 MPa), a cleaner operating environment (no hydraulic oil), and a larger machine footprint (3,800×1,200×2,600 mm). The V3 offers lower capital cost and a more compact installation. See our 3-Station ISBM Models for a full side-by-side comparison.

Can I use my existing ASB-12M moulds on the HGY50-V3?

Yes — the HGY50-V3 uses ASB-12M mould interface dimensions, the same standard as Aoki (ASB) machines widely deployed in Korean factories. Transfer of existing ASB-12M moulds typically requires minimal modification. Korea Ever-Power reviews mould drawings at the quotation stage to confirm compatibility and identify any adaptation required before order confirmation.

What resins can the HGY50-V3 process?

The HGY50-V3 processes PET (standard and high-IV), PETG (thick-wall cosmetic jars at 90–100°C conditioning), PC (high-temperature applications), and Tritan (BPA-free baby bottles and reusable drinkware). PP is also possible with an optional high-temperature barrel configuration — cycle time increases to approximately 22 seconds for 500 ml PP jars. Korea Ever-Power provides resin-specific process parameters during commissioning.

What compressed air supply does the HGY50-V3 require?

A 15–22 kW oil-free screw compressor with 2.5 m³/min flow at 3.5 MPa output pressure — with integrated refrigerated dryer and filters meeting ISO 8573-1 Class 1 air quality. Korea Ever-Power's EP-22KW compressor unit is the recommended matching specification. An oil-free supply is mandatory — oil contamination in the blowing air causes defects in PET bottles and is incompatible with pharmaceutical and cosmetic GMP requirements.

What is a typical cycle time on the HGY50-V3?

Typical cycle time is 12–18 seconds per shot depending on cavity count, container volume, and resin. A 500 ml PET bottle in 2-cavity configuration typically runs at 14–16 seconds; a 4-cavity configuration runs at 18–20 seconds but produces twice the bottles per cycle. Korea Ever-Power can provide cycle time estimates for specific container and cavity configurations at the quotation stage.

What maintenance does the hydraulic system require?

Hydraulic oil should be checked monthly and replaced every 2,000 operating hours or annually, whichever comes first. Hydraulic filter replacement is recommended every 500 hours. The 150-litre oil tank is accessible from the front of the machine. Korea Ever-Power provides a maintenance schedule as part of the machine documentation; remote diagnostic support is available via PLC connection if troubleshooting is required between scheduled service visits.

"We transferred our existing ASB-12M cosmetic jar moulds to the HGY50-V3 — Korea Ever-Power confirmed compatibility before we ordered and the moulds ran without modification on first setup. The bottle clarity on PETG is outstanding. This machine replaced two-step production for our premium jar line."

"We use the HGY50-V3 for pharmaceutical eye dropper bottles in 4-cavity configuration. Neck finish precision is critical — leakage is not an option. After 14 months of 24/7 operation, neck finish consistency has remained within spec every production run. Korea Ever-Power designed our mould and it worked correctly on first shot."

"Good machine at a reasonable price point. The hydraulic system needs attention every 500 hours for filter changes — budget maintenance time accordingly. Cycle time on our 500 ml 2-cavity PET bottles is consistently 15 seconds. Korea Ever-Power's commissioning engineer was thorough and tuned the process specifically for our resin grade."

"We produce Tritan baby bottles — temperature control precision is critical to prevent yellowing. The HGY50-V3 holds barrel temperature within ±1°C across 8-hour production runs. Our cycle time is 14 seconds on 1-cavity Tritan 250 ml bottle. The compact footprint fits our small cleanroom environment without modification."

"We compared the HGY50-V3 to Japanese alternatives — the ROI on the Ever-Power unit was significantly better without compromising bottle quality. The 6-cavity configuration produces 90 ml vials at the output rate we need for our production programme. We are purchasing a second unit this quarter."
