4-cavity PET blow moulding machine 3600BPH

Output: 3600 bottles/hour (BPH)
Cavities: 4
Product: 450ml PET bottle, 35g weight
Cycle time:
- 3600 BPH ÷ 3600 sec/h = 1 bottle/sec
- 4 cavities per cycle = 0.25 cycles/sec → 4.0 sec per cycle
Drive: Servo or electro-hydraulic (depending on configuration)
Blow air pressure: 0.7–1.2 MPa (7–12 bar)
Heating: Multi-zone infrared/shortwave preheater (8–14 zones independent control)

Structure: 4 cavities, fast clamping, interchangeable moulds
Clamping system: Hydraulic or servo, ensures stability & prevents bottle neck deformation
Moulds: High-strength alloy steel (H13 or equivalent), water-cooled, quick-change design
Stretching unit: Servo-controlled stretch rods with programmable stroke & speed
Blow system: Main blow, pre-blow, and exhaust with pressure sensors & safety valves
Control system: PLC + touch screen (HMI), multi-language, recipe management
Safety: Door interlock, emergency stop, overload protection, CE/ISO compliance

Method: Pressure decay or differential pressure detection (fast & non-destructive)
Process: Bottle clamped → pressurized → hold for short time → monitor pressure drop → pass/fail judgment → NG bottle rejected automatically
Sensitivity: Adjustable threshold to detect micro leakage or cracks
Speed: 1–2 sec per test, synchronized with line speed

Function: Counts finished bottles, groups, packs into bags, seals automatically
Bagging type:
- Pre-made bags (automatic opening + filling) OR
- Roll film form-fill-seal system
Capacity: Matches 3600 BPH line speed; grouped packing (e.g., 6, 12, or custom bottles/bag)
Options: Date/batch printing, nitrogen flushing, palletizing connection
