Water, Beverage, Pesticide & Chemical Bottle Blow Molding Machine
About the Series
What Is the Water & Chemical Bottle Blow Molding Machine Series?
This series covers dedicated blow molding machines built around the two-stage PET stretch blow molding process — a method in which preforms are produced or sourced separately, reheated through a segmented infrared oven, axially stretched, and expanded by high-pressure air against a hardened steel blowing mold cavity. The finished container is demolded fully formed, ready for filling, capping, and labeling downstream.
The series spans a wide capability range: from compact 2-cavity machines producing up to 2,400 bottles per hour for small and medium bottling lines, through 4-cavity and 6-cavity platforms reaching 4,600–7,200 bph for mid-to-high volume operations, up to 8-cavity machines at 9,200 bph for large-scale water and beverage production. A separate large-format sub-series handles containers from 5 litres to 22 litres — serving water cooler barrels, industrial chemical drums, and agricultural fluid containers that standard blow machines cannot accommodate.
All models in the series share a common engineering platform: zone-controlled infrared heating, high-pressure air blowing circuits, hardened alloy steel mold systems, and fully automatic preform handling.

Series Configuration Overview
The series divides into four configuration families based on cavity count and container volume, each targeting a distinct output range and application profile.
Entry to Mid Scale
2‑Cavity Configuration
For small‑to‑medium bottling lines
Output
1,800 – 2,400 bph
Контейнердің максималды көлемі
500 – 1,500 ml
Мойынның максималды диаметрі
68 – 98 mm
Peak Heating Power
34 – 42.5 kW
High‑Pressure Air
1,000 – 1,500 ltr/min
Машина салмағы
2,000 – 3,000 kg
Best suited for: Regional water bottlers, craft beverage producers, contract packagers serving multiple SKUs at moderate volumes, and operations where floor space constrains the machine footprint. The 2‑cavity platform is also the most straightforward commissioning and operator training entry point for facilities new to two‑stage PET blow molding.
Mid to High Scale
4‑Cavity Configuration
For established mid‑volume lines
Output
3,200 – 4,800 bph
Контейнердің максималды көлемі
700 – 1,500 ml
Мойынның максималды диаметрі
48 – 98 mm
Peak Heating Power
40 – 68 kW
High‑Pressure Air
3,900 – 5,000 ltr/min
Машина салмағы
3,500 – 5,500 kg
Best suited for: Water bottling plants, beverage contract manufacturers, and agrochemical container producers that need to move beyond 2,500 bph on a single machine without the infrastructure complexity of high‑cavity‑count platforms. The four‑cavity format also delivers the lowest per‑bottle capital cost in the series for operations in the 3,000–4,800 bph throughput planning range.
High Volume
6‑Cavity Configuration
For high‑output production facilities
Output
5,400 – 7,200 bph
Контейнердің максималды көлемі
700 – 1,500 ml
Мойынның максималды диаметрі
38 – 68 mm
Peak Heating Power
62.5 – 72 kW
High‑Pressure Air
5,800 – 9,500 ltr/min
Машина салмағы
5,500 – 6,500 kg
Best suited for: Industrial‑scale water and beverage plants where a single machine needs to anchor a complete production line at 5,000+ bph. The six‑cavity format delivers high throughput on a machine platform that still fits within a single building bay without requiring structural reinforcement beyond standard industrial floor loading capacity, making it a practical choice for facility expansions.
Maximum Output
8‑Cavity Configuration
For the highest single‑machine throughput
Output
9,200 bph
Контейнердің максималды көлемі
700 ml
Мойынның максималды диаметрі
38 mm
Peak Heating Power
72 kW
High‑Pressure Air
7,500 ltr/min
Машина салмағы
6,000 kg
Best suited for: Dedicated high‑speed water bottling plants producing a single standard format (typically 500–700 ml still water) at the maximum throughput rate achievable on a single PET blow molding platform. Infrastructure investment — compressor, chiller, electrical supply — is proportionally larger, and this configuration is most economically justified where multi‑shift operation at full rated speed is the planned production model.
Large Format
Large‑Format / Barrel Configuration
5 L – 22 L containers
Output
700 – 1,000 bph
Контейнердің максималды көлемі
5,000 – 22,000 ml
Мойынның максималды диаметрі
58 – 90 mm
Peak Heating Power
65 – 86 kW
High‑Pressure Air
5,000 – 12,500 ltr/min
Машина салмағы
2,500 – 7,000 kg
Best suited for: Water cooler barrel production (5 L, 10 L, 18.9 L / 20 L, 22 L), large‑format agricultural chemical containers, and industrial fluid packaging where container volume exceeds the practical upper limit of standard multi‑cavity blow molding platforms. Blowing pressure on the largest models reaches 40 kg/cm² to fully expand the high‑mass preforms required for 22 L containers, and cooling water flow rates of up to 120 ltr/min are needed to achieve acceptable cycle times at these container volumes.

How to Choose the Right Blow Molding Machine for Your Application
STEP 1
Define Your Container Specification
Start with the primary container you intend to produce: volume (ml), body diameter (mm), height (mm), and neck diameter (mm). These four dimensions determine which machine platform can physically accommodate your bottle format within its mold envelope. A 500 ml standard water bottle fits almost any model in the series. A 1,500 ml wide-body juice container needs a machine with a 160 mm or larger clamping stroke and a 100 mm or wider mold-close distance. A 10 L water cooler barrel requires the large-format sub-series entirely. Lock down your container specification before looking at output rates.
STEP 2
Set Your Throughput Requirement
Calculate your target daily output in bottles, then divide by planned production hours per day to get the required bph rate. Add a 10–15% operational efficiency buffer to account for minor stoppages, format checks, and preform feeding interruptions. Match the result to the theoretical output ratings across the series: under 2,500 bph points to a 2-cavity machine; 2,500–5,000 bph to a 4-cavity; 5,000–8,000 bph to a 6-cavity; above 8,000 bph to an 8-cavity. For large containers above 1,500 ml, throughput in bph is inherently lower and the large-format series is the relevant comparison group.
STEP 3
Audit Your Utility Infrastructure
Blow molding machines in this series require three utility inputs that must be sized before equipment purchase: high-pressure oil-free air (rated in ltr/min at 35–40 kg/cm²), chilled cooling water (rated in ltr/min at 8–12°C), and three-phase electrical supply (rated in kW peak). Compressor and chiller requirements scale with cavity count. A 2-cavity machine needs roughly 1,000–1,500 ltr/min of high-pressure air; an 8-cavity machine needs 7,500 ltr/min. If existing infrastructure cannot support the cavity count your throughput target requires, factor compressor and chiller capital into the total project cost before committing to machine specification.
STEP 4
Consider Format Flexibility Needs
If your production plan includes multiple bottle formats — different volumes, neck diameters, or body profiles on the same machine — map each format against the machine’s mold envelope and neck diameter range to confirm all formats are within specification. Two-stage machines support format changes through mold swap and heating profile recall; this is straightforward on 2 and 4-cavity platforms and requires more structured change management on 6 and 8-cavity machines where changeover time represents a larger share of daily planned output. For single-format high-volume production, higher cavity counts are more economically efficient. For multi-format operations, 2 and 4-cavity platforms typically offer better changeover economics.
