• Load clean, dry polymer resin into the hopper; pre-drying may be required for hygroscopic materials like PET.
• Set temperature zones along the barrel according to the material’s melting point (e.g., 180°C–250°C for HDPE).
• Input parameters into the PLC (Programmable Logic Controller), including cycle time, blow pressure, and cooling duration.

Safety first: Always perform a test run without material to verify mold alignment and clamp force.

2. Parison Formation

The extrusion phase involves melting and shaping the plastic into a parison.

• The screw inside the barrel rotates, conveying and compressing the resin forward.
• Heating bands melt the plastic gradually, ensuring uniform viscosity.
• The molten plastic exits through the die head, forming a continuous tube (parison) that hangs between open mold halves.
• Modern machines use accumulator heads or continuous extrusion with precision timing to control parison length and consistency.

Quality tip: Monitor melt temperature and screw RPM to avoid degradation or inconsistent flow.

3. Blowing and Cooling

This stage shapes the final bottle and solidifies the plastic.

• The mold closes around the parison, sealing the bottom and neck.
• Compressed air (typically 2–7 bar) is injected into the parison, expanding it to conform to the mold cavity.
• Coolant (usually water or air) circulates through channels in the mold to rapidly cool and solidify the plastic.
• Cooling time affects cycle speed and dimensional stability—too fast can cause stress cracking; too slow reduces output.

Some machines use vacuum assist to improve neck finish accuracy and reduce wall variation.

Pro tip: Optimize blow pressure and cooling time to reduce cycle time without compromising quality.
