Product Overview
The HGS250A is Korea Ever-Power's first large-format model in the HGS Series — the machine that extends semi-automatic PET bottle production from the 1–1.25 L range into containers up to 5 litres. With a 170–250 mm mold capacity, the HGS250A covers the large PET container segment that automatic two-step lines rarely address economically at small-to-medium batch volumes: 2-litre, 3-litre, 4-litre, and 5-litre household, industrial, and agricultural PET bottles where monthly volumes per SKU fall below the threshold for dedicated automatic line production.
The HGS250A shares the same 380×210 mm pillar space and 350 mm stretching stroke as the HGS200A, but its mold capacity starts higher at 170 mm — reflecting that containers in the 5-litre range have larger minimum body diameters that would not fit the lower end of the HGS200A's 120 mm mold range. At 490 kg and 1,600×560×1,450 mm, the HGS250A remains compact enough for standard production floor installation without special structural requirements.
● Large-format PET bottles from 2 L to 5 L at semi-automatic scale
● Operations producing large containers at volumes below automatic line thresholds
● Multi-SKU large-bottle programs: household chemicals, edible oil, water, agricultural
● Sampling and development of 2–5 L PET container formats
Full automatic 2-step lines for 5-litre containers require large capital, long lead times, and minimum run commitments that are uneconomical for producers making 5,000–100,000 units per month. The HGS250A fills this gap — serious production capability without the automatic line investment.
The 170–250 mm mold range covers 2 L, 3 L, 4 L, and 5 L formats on the same machine. Operations producing multiple large-container SKUs — household cleaning, cooking oil, agricultural chemicals — can run all formats with mold changeover rather than maintaining separate automatic lines.
5-litre PET container development and client sample programs — where producing 100–500 approval samples of a new large-format container design requires the same flexibility as smaller containers but the HGS200A's 200 mm ceiling is insufficient for the body width.
Small and mid-size regional bottlers producing 5-litre water, juice, or edible oil in markets where self-blown PET is more economical than purchasing blown containers. The HGS250A's 490 kg and compact 1,600 mm length fit in small warehouse and bottling facility environments.
What the HGS250A Produces — 2 L to 5 L
2-litre to 5-litre PET containers for laundry detergent, fabric softener, floor cleaner, and multi-surface cleaning products. The 250 mm mold capacity accommodates the wide body diameters typical of these large household chemical formats.
3-litre and 5-litre cooking oil PET bottles, large condiment containers, and bulk food-grade PET packaging. Wide-body cooking oil formats with 230–250 mm bodies are a primary application for the HGS250A's upper mold capacity range.
5-litre PET pesticide, herbicide, and fertiliser solution containers. Agricultural chemical PET bottles frequently use wide-body formats in the 220–250 mm body diameter range — the HGS250A's target upper range.
5-litre PET water bottles, large juice containers, and bulk beverage packaging for catering and institutional supply — formats where a semi-automatic line with fast mold changeover serves regional markets more economically than purchasing pre-blown containers.

Core Engineering Features
250 mm Mold Capacity — First to Reach 5 L
The 250 mm maximum mold size is the threshold for producing standard 5-litre PET containers — a format entirely outside the reach of the HGS150A (150 mm) and HGS200A (200 mm). The 170–250 mm range covers 2 L, 3 L, 4 L, and 5 L body diameters, making the HGS250A the most versatile model in the large-format HGS range.
50 mm Sealing Stroke — Stepped Up from HGS200A
The sealing stroke increases from 40 mm (HGS150A / HGS200A) to 50 mm on the HGS250A — reflecting the wider neck finish range of 2–5 L containers. Large-format bottles often use wider or different neck finish standards than 1-litre formats, and the extended 50 mm sealing stroke accommodates this variety.
250 mm Open Mold Stroke — Clearance for Wide Bodies
The open mold stroke increases from 200 mm (HGS200A) to 250 mm to provide adequate clearance for 5-litre container bodies during mold opening — the wider the container body, the more mold opening stroke is required for the blown bottle to clear the mold halves without contact. At 250 mm open stroke and 250 mm max mold size, the HGS250A is correctly sized for 5-litre geometry.
490 kg — Lightest 5-Litre Semi-Automatic Configuration
At 490 kg, the HGS250A is only 10 kg heavier than the HGS200A despite handling containers four times larger in volume. This reflects Korea Ever-Power's compact toggle mechanism design — the mold clamping force required for 5-litre containers at 3.0 MPa blowing pressure is achieved without adding significant structural mass to the machine frame.
500–980 BPH at 5 Litres — Practical Output Planning
5-litre containers have greater preform conditioning time and longer blow cycle duration than 1-litre formats. Realistic sustained operator output for 5-litre round bottles is 600–750 BPH over a full shift — producing 4,100–5,100 bottles per 8-hour shift. At 700 BPH on a 22-day monthly schedule with two shifts, the HGS250A produces approximately 220,000 5-litre containers per month.
Compact 1,600×560 mm Footprint for Large-Format Production
Only 50 mm longer than the HGS200A despite handling containers up to four times the volume. The 1,600 mm length and 560 mm width fit the HGS250A into standard warehouse and bottling facility environments where 5-litre large-format production is needed without a dedicated large-format production hall. The heater unit is placed adjacently with short preform transfer distance.
Large-format PET bottles from 2 L to 5 L — household chemicals, cooking oil, agricultural chemicals, and bulk beverages — the primary applications for the HGS250A.

Frequently Asked Questions
Can the HGS250A produce both 2-litre and 5-litre bottles?
Yes — the 170–250 mm mold capacity range covers 2 L, 3 L, 4 L, and 5 L body diameters. Changeover between sizes requires a mold change (10–20 minutes) and potentially a heater zone profile adjustment for the different preform size. Many operators run the HGS250A across two or three large-container SKUs on a weekly rotation. Check the full HGS Series if you need containers beyond 5 litres.
Why is the sealing stroke 50 mm on the HGS250A but 40 mm on the HGS200A?
Large-format containers (2–5 L) frequently use different neck finish standards with wider thread diameters than 1-litre bottles. The 50 mm sealing stroke provides the additional travel needed to correctly seat and seal the blow pin against a wider range of large-container neck finish geometries. The 40 mm stroke on the HGS150A and HGS200A is sufficient for standard 1-litre neck finishes but may not accommodate all large-container formats.
What is a realistic sustained BPH for 5-litre bottles on the HGS250A?
For standard round 5-litre bottles with a well-tuned heater, a trained operator typically sustains 600–750 BPH over a full shift — the longer preform conditioning time and larger blow cavity extend the per-bottle cycle versus 1-litre formats. At 700 BPH over an 8-hour shift at 85% utilisation, production is approximately 4,760 bottles per shift. For wide-body or contoured 5-litre formats, expect 550–650 BPH due to additional mold open/close time requirements.
Does the HGS250A need a different air supply from the HGS200A?
No — both machines use 0.8 MPa operating pressure and 3.0 MPa blowing pressure. Operations already running the HGS200A can add an HGS250A to the same 0.8 MPa air supply line. Note that 5-litre containers consume more high-pressure air per cycle than 1-litre containers due to the larger cavity volume — verify that your 3.0 MPa compressor has sufficient flow capacity for the additional machine before connecting.
What monthly volume is realistic from one HGS250A on two shifts?
At 700 BPH sustained and 85% shift utilisation over 8 hours, each shift produces approximately 4,760 bottles. On a 22-day monthly schedule at two shifts, output is approximately 209,000 five-litre containers per month — sufficient for mid-size regional household chemical, cooking oil, or agricultural chemical bottlers producing across 2–4 SKUs with weekly changeovers.
Customer Reviews
"We produce 5-litre laundry detergent PET bottles — about 180,000 per month across 3 SKUs. The HGS250A handles all three on a weekly rotation with 15-minute mold changeovers. Sustained output on our widest format (235 mm body) is around 640 BPH. Investment was a fraction of the automatic line we were quoted."
HGS250A
"We use the HGS250A for 3-litre and 5-litre cooking oil bottles — both formats within the 250 mm ceiling. The 50 mm sealing stroke handles our wide-mouth neck finish correctly. Commissioning was done by Korea Ever-Power's team on-site. Heater zone tuning for our 5-litre preform took about 3 hours to get right — worth the time."
HGS250A
"Good machine for 5-litre bottles. Realistic BPH note: our operator sustains 650–700 BPH on standard 5-litre round formats — plan your schedule around 680 BPH as a production basis, not the 980 BPH peak. Korea Ever-Power was straightforward about this during the quotation stage. Machine has been reliable over 14 months."
HGS250A
"We use the HGS250A for 5-litre agricultural herbicide container samples and small initial production runs — 500 to 5,000 units per new formulation. The fast changeover between our 3-litre and 5-litre sample molds (about 12 minutes) allows us to respond to client requests same day. Our permanent HGS250A covers our full development pipeline."
HGS250A
"We are a regional 5-litre water bottler — 160,000 bottles per month. The HGS250A on two shifts at 720 BPH sustained comfortably covers our monthly volume with a small buffer for maintenance. The 1,600 mm machine length fits in our existing bottling line space without modification. Very compact for a 5-litre machine."
