EP-HGS-350A Semi-Automatic 20L PET Blow Molding Machine
The largest machine in the HGS semi-automatic series — for 20-litre (5-gallon) water barrels and large-format PET containers. At 150–400 bph, it serves producers whose 20-litre annual volume does not yet justify the capital investment of a fully automatic JS-series barrel machine. Single-cavity, piston-type or cylinder hinge locking.
HGS-350A vs JS-2C366 — Semi-Auto vs Full-Auto for 20L
Both the HGS-350A and the EP-HGA.JS-2C366 produce 20-litre PET barrels. The correct choice depends on your annual production volume and capital investment capacity.
| காரணி | HGS-350A (Semi-Auto) | JS-2C366 (Full-Auto, 2-Cavity) |
|---|---|---|
| Max Output | 150–400 bph | 40–80 bph × 2 cavities |
| Preform Loading | Manual | Fully automated |
| Capital Cost | Lower | Higher |
| Best For | Regional / startup 20L production | Established large-volume 20L lines |
Machine Overview
தி EP-HGS-350A is the largest machine in the HGS semi-automatic series — purpose-built for 20-litre (5-gallon) PET water barrels and other large-format containers. At 150–400 bph and 1,500kg, it is a substantially larger machine than the rest of the HGS series, reflecting the scale of the 20-litre container format. The machine operates on 220V/50Hz single-phase power and uses piston-type or cylinder hinge locking configurations.
The 20-litre water barrel is the globally standardised format for home and office water delivery services and water cooler dispensers. The HGS-350A is selected by regional water delivery operators, packaging companies supplying water brands, and producers entering the 20L market whose annual barrel volume does not yet justify the capital investment of a fully automatic JS-series barrel line. The 150–400 bph output corresponds to approximately 1.2–3.2 million barrels per year at 8,000 operating hours — the typical scale for regional operations.
For fully automatic 20L barrel production, the EP-HGA.JS-2C366 fully automatic 2-cavity water barrel machine or the EP-HGA.J-2C366 edible oil barrel variant are available. Browse all semi-automatic machines.

Cameroon — Water Delivery Operator
★★★★★
Application: 20-litre PET water barrels for a Yaoundé-based home and office water delivery operator serving residential and corporate clients across Yaoundé and Douala.
Problem solved: The operator was importing PET barrels from a Cameroonian distributor at a per-barrel cost that compressed margins on the competitive water delivery market. The HGS-350A enabled in-house barrel production at a volume level appropriate for their regional operation — below the threshold that would make a fully automatic barrel line economically justifiable. Per-barrel production cost decreased by 34% versus the imported barrel price.
“34% per-barrel saving, no import dependency. Our volume was too small for a full-auto line. The HGS-350A was exactly the right scale — regional production at regional volume.”
Sri Lanka — Bottled Water Brand
★★★★★
Application: 20-litre PET water barrels for a Colombo-based bottled water brand entering the home and office delivery market for the first time with an in-house barrel production capability.
Problem solved: The brand needed to launch a 20-litre water delivery service without committing to a fully automatic barrel machine at launch volumes. The HGS-350A provided the production capability to supply the delivery fleet from day one, with the understanding that a transition to fully automatic production could be made as the delivery network grew beyond the semi-automatic output ceiling.
“We launched the 20L delivery service with the HGS-350A at the capital level we could justify at launch. The plan was always to move to full-auto when the route count warranted it — the semi-auto got us to market first.”
Philippines — Chemical Packaging Company
★★★★★
Application: 20-litre PET industrial liquid containers for a Manila-based chemical packaging company serving industrial cleaning product and water treatment chemical brands.
Problem solved: The packager’s 20-litre industrial container volume was split across multiple chemical brands, with no single brand’s volume justifying dedicated fully automatic production. The HGS-350A’s semi-automatic configuration allowed the packager to serve multiple 20L accounts with changeover between container specifications, covering the full range of 20L industrial clients from one machine installation.
“Multiple 20L clients, different container specs, small volumes per client. The semi-auto changeover is what makes this work — fully automatic would lock us into one spec per machine.”
