Fully Automatic PET Stretch Blow Moulding Machine manufacturer

A Fully Automatic PET Stretch Blow Moulding Machine makes PET bottles from PET preforms without needing constant manual work.

The machine takes care of almost everything on its own. It heats the preform, moves it into the moulding section, stretches it, and then shapes it into a bottle using compressed air. Once the bottle is cooled, it comes out of the machine automatically.

This is why manufacturers who want steady, high-volume bottle production usually prefer a fully automatic setup — and it's exactly what Suraj Plastic Industries specializes in as a leading Fully Automatic PET Stretch Blow Moulding Machine Manufacturer.

Here's the bottle-making process in 6 easy steps:

PET Preform → Heating → Transfer → Stretching → High-Pressure Blowing → Bottle Ejection

Preform Feeding – PET preforms are loaded into the machine and set in the right position automatically.

Preform Heating – The preforms are heated evenly so they're ready to be shaped properly.

Mould Transfer & Clamping – The heated preform moves into the mould, which then closes tightly around it.

Stretching – The preform is stretched vertically to prepare it for blowing.

High-Pressure Blowing – Compressed air pushes the preform outward until it takes the shape of the mould, forming the bottle.

Cooling & Ejection – The finished bottle is cooled and automatically pushed out, ready for the next stage.

As a leading Fully Automatic PET Stretch Blow Moulding Machine Manufacturer, Suraj Plastic Industries builds the SPI AY Series with features that make PET bottle production faster and easier:

• Fully automatic production — start to finish
• Available in 2, 4 and 6 cavity models
• Production capacity up to 6,000 BPH
• Even, controlled preform heating
• Automatic preform feeding
• Smooth stretching and high-pressure blowing
• Automatic bottle ejection
• Easy-to-use OMRON PLC with touchscreen control
• Configurations available for 600 ml, 1.5 L and 2 L bottles
• Machine models tailored to your production needs
• The machine also comes with a layered heating system and an automated preform feeding setup, keeping the whole line running without much manual effort.

Picking the right machine depends on your bottle size and how many bottles you need per hour.

4-cavity: up to 4,000 BPH 6-cavity: up to 6,000 BPH Great for businesses needing high-volume 600 ml bottle production.

2-cavity: up to 2,000 BPH 4-cavity: up to 3,600 BPH

2-cavity: up to 1,800 BPH 4-cavity: up to 3,600 BPH

More cavities mean more bottles produced per cycle, but that doesn't always mean more is better.

• 2-Cavity: Good for moderate production and certain larger bottle sizes.
• 4-Cavity: Offers higher output and is available across most SPI AY models.
• 6-Cavity: Best for high-volume needs — the SPI AY600-6 model alone can produce up to 6,000 BPH for 600 ml bottles.

The best choice depends on your bottle size, daily production target, preform type, available utilities and future growth plans — not just the highest number available.

Fully automatic PET blow moulding machines from Suraj Plastic Industries are used to make bottles and containers for:

• Packaged drinking water

The exact machine and mould setup depends on your product type, bottle design and production goals.

Before buying a fully automatic PET bottle machine, keep these points in mind:

Go for Fully Automatic if you need:

• Higher production output
• Less manual handling
• Consistent, repeatable production
• Automatic preform handling
• Non-stop production runs
• Easy connection with packaging lines

Semi Automatic works well if:

• Your production volume is moderate
• Some manual handling is acceptable for your setup

• Your required bottle size
• Production target
• Cavity configuration needed
• PET preform specifications
• Bottle design
• Compressed air availability
• Power requirements
• Cooling setup
• Application/product type

This way, you get a machine that actually fits your business — not just one with the highest BPH number on paper.

When choosing a PET bottle blowing machine, always start with your actual production needs — not just the machine's top speed.
