SERVO DRIVE SYSTEM
Full 4-Axis Servo Drive — Faster, Quieter, 30% More Energy Efficient
Every Sailwin fully automatic PET stretch blow molding machine ships with independent servo motors on all four critical axes — eliminating hydraulic oil and pneumatic cylinders from the drive system entirely.
Servo-Driven vs Pneumatic-Driven — Why It Matters
| Comparison | ✓ Servo-Driven (Sailwin Standard) | Pneumatic-Driven (Traditional) |
|---|---|---|
| Production Speed | 30% Faster Programmable motion curves | Fixed speed Limited by air valve response |
| Noise Level | < 72 dB Quiet, cleanroom-friendly | > 85 dB Continuous air exhaust noise |
| Energy Consumption | Save 30% On-demand power draw | Higher Constant compressed air waste |
| Positioning Precision | ± 0.1 mm Encoder closed-loop feedback | ± 0.5 mm Open-loop air cylinder |
| Maintenance Cost | Low No seals or valves to replace | Higher Frequent seal replacement |
Sailwin Standard on All Models
Full 4-Axis Servo — No Hydraulics, No Compromise
- Siemens / Mitsubishi servo motor & drive
- Programmable motion curve per product type
- FESTO 3-in-1 combination blow valve
- PID infrared oven with neck cooling fan
- Air recovery system (high-speed models)

TURNKEY AUTOMATION
Auto Preform Loader & Inline Bottle Unloader
— Zero Manual Intervention
Manual preform feeding is the single biggest labor bottleneck in automatic PET blow molding production. Each shift requires 1–2 dedicated loaders — which adds cost, inconsistency and fatigue errors. Sailwin's fully automatic PET stretch blow molding machines are designed to integrate seamlessly with automated preform loading and bottle unloading systems.
Auto Preform Loader
Vibratory bowl + linear track system. Feeding speed ≥ machine output × 1.2 for continuous buffer. Compatible with 28mm / 30mm / 38mm / 45mm neck sizes.
Auto Bottle Outlet Conveyor
Synchronized conveyor belt connects directly to filling line. Speed auto-matches machine output. Linear PET blow molding machine outlet is compatible with mainstream filler interfaces.
Reject Gate for Defective Bottles
Automatic rejection of short shots, deformed or cold preform bottles. No manual sorting required. Defect rate data logged to HMI dashboard.
Turnkey Blow-Fill Line Available
Request complete turnkey quotation: automatic PET blow molding machine + preform loader + air conveyor + filling machine interface. One supplier, one warranty.
