3. Three-Station Process Detailed Explanation

Station 1: Precision Injection Molding Plastic pellets are processed through an automatic drying and dehumidification system before entering the injection unit barrel. Under precise temperature control, the material is uniformly plasticized and then injected into the injection mold cavity at preset pressure and speed.

Technical Features:

• Bottle neck threads formed with precision in single operation, meeting DIN standards
• Optimized preform wall thickness distribution through multi-point control
• Elimination of weld lines ensures preform structural integrity
• Rapid cooling system shortens molding cycle

Quality Control Points:

1. Neck dimension accuracy: Critical diameter tolerance ±0.02mm
2. Thread integrity: No flash, no short shots
3. Wall thickness uniformity: CV value <3%
4. Crystallinity control: Ensures optimal stretch performance

Station 2: Stretch Blow Molding The rotary table precisely rotates 120°, transferring the partially cooled but temperature-optimized preform to the stretch blow station. Here, the preform is reheated to optimal stretching temperature, then axially stretched by the stretch rod while high-pressure air enables radial expansion.

Key Technical Parameters:

• Stretch speed: Adjustable 100-500mm/s
• Blow pressure: Adjustable 15-35bar
• Stretch ratio: Axial 1.5-3.0, Radial 2.0-4.0
• Molding time: 3-15 seconds (depending on container size)

Molding Advantages:

1. Biaxial Orientation Enhancement: Molecular chain orientation significantly improves container mechanical strength
2. Clarity Optimization: Eliminates crystalline haze, transparency up to 90%+
3. Barrier Improvement: Gas barrier properties increased 3-5 times
4. Lightweight Capability: 10-20% weight reduction compared to conventional methods

Station 3: Automatic Ejection & Product Collection The rotary table rotates another 120°, transferring the formed container to the ejection station. The ejection system smoothly pushes containers from the blow mold onto conveyors or robotic handling systems.

Ejection System Features:

• Multi-point multi-stage ejection design prevents container deformation
• Vacuum suction or mechanical gripping ensures transfer stability
• Automatic counting and defect separation
• Optional online inspection and labeling systems

Production Cycle Control:

• Standard cycle time: 8-25 seconds (depending on container size/complexity)
• Time synchronization optimization: Precise matching of three-station actions
• Mold open/close time: ≤2 seconds
• Ejection/reset time: ≤1.5 seconds
