STRETCH BLOW MOLDING
PET Blow Molding Machines
Fully automatic linear and rotary-type PET stretch blow molding machines. 2 to 9 cavities, capacities from 800 to 16,000 BPH for water, CSD, edible oil, wide-mouth jars and 5-gallon containers.
EXTRUSION BLOW MOLDING
Extrusion Blow Molding Machines (EBM)
Heavy-duty blow molding equipment for HDPE, PP and PE hollow containers (0.5L–1,000L). Engineered for jerrycans, lube oil bottles, chemical drums, IBC tanks, and 6-layer EVOH barrier packaging.
INJECTION MOLDING SYSTEM
PET Preform Injection Molding Machines
Factory-direct SW-P Series PET preform injection machines across 14 models (170–5500 kN clamping force). Equipped with high-torque plasticizing screws and servo motors saving 30%–50% energy.
BOTTLING & PACKAGING
Liquid Filling Machines & Bottling Lines
Complete 3-in-1 monoblock filling systems (washing, filling, capping) for bottled mineral water, carbonated soft drinks, juice, edible oil, and daily chemicals. Capacities from 2,000 to 18,000 BPH.
MANUFACTURING EXCELLENCE
Precision Engineering & Core Component Standards
Sailwin machines are engineered with tier-1 international automation components, robust mechanical frameworks, and advanced energy-saving circuits to ensure 24/7 continuous industrial reliability.
Siemens PLC & Festo / SMC Pneumatics
We build with zero generic electrical clones. All control logic is powered by Siemens S7 series PLC with multi-language industrial touchscreens, Schneider electrical contactors, and Festo / SMC high-speed valves.
- ✓ Recipe management: store up to 100+ bottle preform mold parameters for 15-minute quick changeover.
- ✓ Microsecond response valves ensure exact stretch-rod positioning and zero bottle wall thickness drift.
Dual-Stage Air Recovery & 30%–40% Power Savings
Compressed air is the single largest operational cost in PET bottle blowing. Sailwin equips high-pressure machines with an intelligent Dual-Stage Air Recovery System, capturing exhaust 30–40 bar air back into low-pressure pneumatic actions.
- ✓ Recovers up to 30%–45% of high-pressure air, eliminating the need for independent low-pressure air compressors.
- ✓ Servo-driven mold clamping and mold traverse drastically reduce power consumption during idle cycles.
100-Point Parison Control & Precision Spiral Die Head
For HDPE jerrycans and drums, uniform wall thickness is vital for passing stringent drop-impact and stacking tests. Sailwin extrusion die heads are forged from 38CrMoAlA alloy steel with deep nitriding treatment and mirror polishing.
- ✓ Standard 100-point parison wall thickness programmer (MOOG or precision servo valve control).
- ✓ Heart-shaped spiral flow channel eliminates internal weld lines and prevents resin carbonization.
ZERO-DEFECT STANDARD
5-Stage Quality Inspection & Factory Verification
Every Sailwin machine undergoes comprehensive dry-cycle testing and 72-hour continuous mold trial before crating. We ensure overseas buyers receive factory-ready equipment requiring minimal commissioning.
Raw Material & Steel Spectroscopy
Spectrometric verification of tie-bar steel, screw alloys (38CrMoAlA), and mold cavity materials (P20 / 7075-T6 aluminum) prior to machining.
CMM 3D Precision Coordinate Inspection
Micron-level measurement of mold cavities, neck rings, and clamping platens to ensure bottle symmetry and zero parting line flash.
24-Hour Continuous Dry-Cycle Aging
Full electrical, pneumatic, and hydraulic components run non-stop for 24 hours to monitor temperature rises and valve responsiveness.
72-Hour Mold Sampling & Bottle Pressure Test
Test-running actual customer resins and preforms. Verification of bottle burst pressure, drop impact test, and top-load vertical strength.
CE Safety Compliance & Export Packaging
CE European Machinery Directive compliance, optical safety light curtains, emergency stop logic, and vacuum-sealed anti-rust seaworthy packing.
FACTORY IN-SITU TESTING
In-house engineer verifying clamping platen parallelism and infrared heating profile.
CE & ISO 9001 CERTIFICATIONS
Accredited European CE compliance and ISO 9001:2015 quality management system certificates.
GLOBAL TRACK RECORD
