Overview
The DEXIN high-speed blow molding machine makes PET bottles from 0.2 L to 2 L for water, carbonated drinks, juice, edible oil and daily chemicals. It is a linear, fully automatic stretch blow molder: preforms are loaded, heated, moved by a servo-driven variable-pitch mechanism and blown into bottles in one continuous cycle.
Seven models cover 6 to 12 cavities and 14,000–28,000 bottles per hour on 0.5–0.6 L bottles. SS models use a small 80 / 76.2 mm pitch and are built for high-speed water bottles; S models use a 120 mm pitch for bottles up to 2 L and 105 mm diameter.
Lower running cost
Compressed air is the largest running cost in blow molding. An integrated sealed valve block cuts high-pressure air consumption by about 33% compared with conventional linear machines, and a separate high-pressure air circuit reduces valve wear, lowering maintenance cost by up to 90%.
Stable output in any plant
Constant-voltage heating keeps preform temperature steady when the local grid fluctuates, and every heating lamp is monitored, so a failed lamp raises an alarm before it produces rejects. The machine is controlled by a Siemens PLC with a touch-screen HMI that logs production data and diagnoses faults.
Key features
Why this machine uses less air and power
-
Integrated sealed valve block
Four high-pressure valves combined in one sealed block shorten the air path and cut high-pressure air consumption by about 33%.
-
High-pressure air separation
US-made high-speed high-pressure solenoid valves on a separate air circuit wear less, lowering maintenance cost by up to 90%.
-
Full servo drive with linkage
Servo motors combined with a linkage mechanism give fast, repeatable motion at high speed with low energy use.
-
Constant-voltage heating
Heating output stays stable when the grid voltage fluctuates, so bottle wall thickness stays consistent.
-
Heating lamp failure alarm
Each lamp is monitored; a failed lamp raises an alarm at once, reducing rejects and raising the pass rate.
-
Up to 2,500 BPH per cavity
High output per cavity means fewer cavities, a shorter machine and less floor space for the same output.
How it works
From preform to finished bottle
-
Preform loading
The automatic loader feeds and orients preforms into the machine.
-
Infrared heating
Preforms rotate through the constant-voltage oven to an even blowing temperature.
-
Variable-pitch transfer
The servo variable-pitch mechanism spaces the hot preforms to the mould pitch.
-
Stretch blowing
The mould closes, the stretch rod extends and 3.4 MPa air forms the bottle.
-
Bottle discharge
Finished bottles leave on the air conveyor, ready for filling.

FAQ
Questions buyers ask
Not answered here? An engineer will reply on WhatsApp or email.
What bottle sizes can this machine make?
PET bottles from 0.2 L to 2 L. SS models (L6SS, L7SS, L8SS, L10SS, L12SS) are built for 0.5–0.6 L water bottles at the highest speed; S models (L6S, L8S) take bottles up to 2 L and 105 mm in diameter.
How many cavities do I need?
Divide your target output by about 2,300 bottles per hour per cavity for 0.5–0.6 L water bottles. For example, 14,000 BPH needs 6 cavities (L6SS), 24,000 BPH needs 10 (L10SS) and 28,000 BPH needs 12 (L12SS). Send us your bottle drawing and preform weight and we will confirm the model.
How much compressed air does it save?
The integrated sealed valve block uses about 33% less high-pressure air than a conventional linear blow molder. High-pressure air consumption for each model, from 6 to 12 m³/min, is listed in the specification table.
What utilities does the machine need?
High-pressure air at 3.4 MPa (35 kg/cm²), chilled water at 10–12 °C for the moulds, cooling water at 30 °C and 2–4 kg/cm², and an electrical supply for 50–100 kW installed power depending on the model.
Which control system and key components do you use?
A Siemens PLC with a touch-screen HMI, a full servo drive, and US-made high-speed high-pressure solenoid valves.
Can one machine make several bottle sizes?
Yes. Moulds are quick-change, so one machine can run several bottle shapes within its size range. Tell us every bottle you plan to make and we will choose the pitch (SS or S) that covers them.
