If you are producing 20 liter water jars or 5 gallon bottles, you already know:
Preforms are thick and heavy
Neck size is large
Injection pressure must be strong
Machine must run stable for long hours
That is why a normal injection machine cannot handle this job.
Our 5 gallon preform injection machine is specially designed for 20 liter jar PET preform production, built as a true heavy duty injection molding machine with reinforced clamping system and high torque PET screw.
One-Stop Solution: Complete system with injection machine, mold, dryer, chiller, and robot.
Easy Start: User-friendly interface, pre-calibrated for quick commissioning.
Low Investment: Optimized for mid-to-low volume production with fastest ROI.
Energy-Saving & Eco-Friendly: Optimized power consumption for lower operational costs.
High Precision & Repeatability: Stable molding ensures consistent quality for complex parts.
Fast Plasticizing & Efficient Production: Short cycle times and improved throughput.
Low Noise Operation: Creates a safer and more comfortable working environment.
Material: PET, PLA, and other thermoplastics.
Cavity Options: 12 / 16 / 24 / 32 cavities for flexible output.
Key Features:
High repeatability and low flash - ensures consistent weight and neck finish.
Optimized cooling and drying system - reduces cycle time and improves clarity.
Energy-efficient injection - lower power consumption and operational cost.
Material: PP, PE, or other suitable plastics.
Precision Molding: Guarantees tight sealing, smooth threads, and uniform thickness.
Auxiliary Equipment: Dehumidifying dryer and chiller included to ensure stable cycles and quality consistency.

No. Although optimized as a 5 gallon preform injection machine, it can also produce:
3 gallon preforms
10L jar preforms
Customized large neck PET preforms
Normally, heavy preforms require high tonnage.
Our heavy duty injection molding machine is configured according to:
Preform weight
Cavity number
Neck diameter
We recommend sharing your drawing for exact calculation.
Output depends on:
Cavity number
Preform weight
Cooling time
For example:
4 cavity 5 gallon preform injection machine
Stable 20 liter jar PET preform machine cycle
Output customized based on your demand
We can calculate exact BPH after receiving your preform details.
Compared to conventional machines, this heavy duty injection molding machine uses servo system control to reduce energy cost significantly.
For 24-hour operation factories, this saves substantial annual electricity expenses.
Yes.
We supply:
5 gallon preform molds
20 liter jar PET preform molds
Customized heavy wall molds
Complete solution = machine + mold + technical support.
Whole-hearted service every day!
