A Fully Automatic Stretch Blow Moulding Machine is an industrial machine used to manufacture PET (Polyethylene Terephthalate) bottles, jars, and containers through a two-stage or single-stage stretch blow moulding process. This machine heats PET preforms and then stretches and blows them into a mould cavity using high-pressure air, producing bottles used in packaging industries such as beverages, pharmaceuticals, edible oils, cosmetics, and household chemicals.
Unlike semi-automatic machines that require manual preform loading and bottle unloading, a fully automatic machine handles the entire cycle — preform feeding, heating, stretching, blowing, and bottle ejection — without manual intervention. This results in higher output, consistent bottle quality, and lower labour dependency.
At Suraj Plastic Industries, we design and manufacture Fully Automatic Stretch Blow Moulding Machines that are trusted by packaging manufacturers across India for their durability, precision engineering, and after-sales support.
Fully Automatic Stretch Blow Moulding Machine — High Speed. Zero Compromise.
When your production target demands speed, consistency, and round-the-clock reliability — a fully automatic stretch blow moulding machine is the answer.
AtSuraj Plastic Industries, we manufacture fully automatic PET preform stretch blow moulding machines designed for high-volume bottle production. With output capacities reaching up to 7200 bottles per hour, intelligent PLC control systems, and 2, 4, and 6 cavity configurations — our machines are built for manufacturers who cannot afford downtime or inconsistency.
Whether you run a large packaged drinking water plant, a beverage production line, or an FMCG packaging unit — this machine delivers the output you need, shift after shift.
What Is a Fully Automatic Stretch Blow Moulding Machine?
A fully automatic stretch blow moulding machine converts PET preforms into finished bottles — with zero manual intervention at any stage.
Here is how the process works:
Step 1 — Automatic Preform Loading
PET preforms are loaded into the hopper. The machine automatically feeds, orients, and positions each preform — no operator needed at this stage.
Step 2 — Infrared Heating
Preforms pass through an infrared heating zone. The temperature is precisely controlled by a PLC system to ensure every preform is heated uniformly before entering the mould.
Step 3 — Stretch Blowing
The heated preform enters the mould. A stretch rod extends it vertically while high-pressure air (up to 25 KG/CM²) expands it outward against the mould walls — forming the final bottle shape.
Step 4 — Automatic Bottle Ejection
The finished bottle is automatically ejected and moved to the output conveyor — ready for filling, capping, and labelling downstream.
The entire cycle happens continuously and automatically — no operator contact, no manual loading, no manual ejection. Pure production.
Our Fully Automatic Machine Range — 6 Models
We offer 6 models to match different bottle sizes and output targets:
| Model | Bottle Size | Output (BPH) | Cavities | Connected Load |

| SAB-500-6B | 50 ML – 500 ML | 5400–6000 | 6 Cavity | 60 KW |
| SAB-1000-2B | 100 ML – 1000 ML | 1700–2000 | 2 Cavity | 36 KW |
| SAB-1000-4B | 100 ML – 1000 ML | 3400–4000 | 4 Cavity | 48 KW |

Key Features of Our Fully Automatic Stretch Blow Moulding Machine
Fully Automatic vs Semi-Automatic Stretch Blow Moulding Machine
| Parameter | Fully Automatic Machine | Semi-Automatic Machine |
|---|---|---|
| Operator Involvement | Minimal (loading/unloading automated) | Manual preform loading & bottle removal |
| Production Speed | High output, suited for large-scale production | Lower output, suited for small-scale production |
| Labour Cost | Lower, since process is automated | Higher, due to manual handling |
| Consistency | High consistency across batches | Depends on operator skill |
| Initial Investment | Higher upfront cost | Lower upfront cost |
| Best Suited For | Medium to large PET bottle manufacturers | Small-scale or startup manufacturers |
Choose semi automatic if: You are starting out, have a smaller production target, or want to keep initial investment low.
Choose fully automatic if: You have a large production target, want to minimise labour dependency, and need maximum output consistency at scale.
