Product Overview
The HGS150A is Korea Ever-Power's entry-level semi-automatic PET stretch blow molding machine — the most compact and accessible model in the HGS Series. Operating with a 330×220 mm pillar space and a mold capacity range of 100–150 mm, it produces PET bottles up to 1 litre at output rates between 500 and 1,100 BPH depending on operator pace, bottle geometry, and preform conditioning temperature.
The HGS150A uses Korea Ever-Power's pneumatic hydraulic linkage mold-locking system — a proven toggle-style mechanism providing consistent clamping force across the mold parting line without hydraulic pump complexity. The machine is equipped with a digital infrared preform heating system (supplied as the matching HGJ-CL or HGJ-B heater unit, sold separately) and a 320 mm stretching stroke suited to standard 1-litre PET bottle proportions.
At 400 kg and 1,400×500×1,500 mm, the HGS150A is the smallest and lightest machine in the HGS range — installable in small factory spaces, pilot production areas, and product development environments where a full automatic line is not warranted by production volume.
A single HGS150A — machine plus heater — represents a fraction of the capital cost of a full automatic 2-step line. For operations starting PET bottle production or adding a secondary format, the semi-automatic route removes the financial barrier to entry.
Manual mold mounting means changeover between bottle formats takes minutes rather than hours. For operations running multiple SKUs at low-to-medium volumes — 3 to 8 different bottle designs per week — the HGS150A's flexibility outperforms a single-format automatic line.
New bottle designs, client sample requests, and packaging development programs are naturally suited to semi-automatic production. One operator can produce 50–500 sample bottles per run without committing a full automatic line to a short non-production run.
Orders of 500–50,000 units per SKU per month are typically uneconomical on full automatic lines due to changeover downtime and minimum run requirements. The HGS150A at 500–1,100 BPH covers this volume range efficiently with a single operator.
What the HGS150A Produces — Up to 1 Litre
Standard PET beverage bottles from 250 ml to 1 litre — juice, water, soft drink, and functional beverage formats within the 100–150 mm mold capacity range at up to 1,100 BPH operator pace.
Shampoo, conditioner, body wash, and lotion containers up to 1 litre. PET clarity and surface finish quality suitable for retail personal care packaging at small-to-medium batch volumes.
Sauces, vinegars, cooking oils, and condiment bottles up to 1 litre in PET. The HGS150A's manual operation allows easy adjustment between different preform neck finishes used across condiment formats.
New bottle development, packaging agency sample production, and client approval runs at 50–2,000 units per new design — the primary use case for semi-automatic production where per-run setup time is minimal.
Pharmaceutical intermediate packaging, laboratory reagent containers, and specialty chemical PET bottles up to 1 litre. The HGS150A's mold-locking mechanism handles the variety of neck finishes common in pharmaceutical PET.

Core Engineering Features
Pneumatic Hydraulic Linkage Mold Locking
The toggle-type mold-locking mechanism uses pneumatic hydraulic linkage rather than a direct hydraulic cylinder — a simpler, more maintenance-accessible design that provides consistent clamping force at the mold parting line without a hydraulic pump system. This is the standard mechanism across the HGS series and contributes to the machine's compact footprint and lower operating cost.
Digital Infrared Preform Heating
The matching HGJ heater unit uses digital infrared zone control to condition preforms to the correct blow temperature before transfer to the blow station. The HGS150A is designed to work with either the HGJ-CL (96-position, standard neck up to 68 mm) or the HGJ-B (18/36-position, wide neck up to 130 mm) — the heater selection depends on the preform neck finish and production volume required.
320 mm Stretching Stroke — Standard 1L Geometry
The 320 mm stretch rod travel covers the height range of standard 1-litre PET bottle formats including slim, standard, and slightly taller configurations. The stretch ratio at 320 mm is optimised for 1-litre preform proportions — a longer stroke is available in the larger HGS models for taller containers in the 5–20 litre range.
500–1,100 BPH — Operator-Driven Output Range
Output on the HGS150A ranges between 500 and 1,100 BPH depending on operator pace, preform conditioning time (heater throughput), and bottle geometry complexity. At 1,100 BPH with a skilled operator and a matched HGJ-CL heater running at full capacity, the machine approaches the lower range of small automatic blow molding machines — at a fraction of the capital cost and with full mold changeover flexibility.
Smallest HGS Footprint — 1,400×500 mm
At 1,400×500×1,500 mm and 400 kg, the HGS150A fits in production spaces where no other model in the HGS range can be accommodated. The 500 mm width is narrow enough to install alongside existing equipment on a standard production floor without dedicated space allocation. At 400 kg, it requires no special floor loading assessment in most industrial buildings.
0.5–0.7 MPa Operating Pressure — Lowest in HGS Range
The HGS150A operates at 0.5–0.7 MPa working pressure versus the 0.8 MPa of the larger HGS models — reflecting its smaller mold clamping requirements. Blowing pressure is 3.0 MPa across all HGS models. Many facilities already have 0.6–0.7 MPa compressed air systems installed for pneumatic tooling — the HGS150A can often be connected to existing facility air without additional compressor investment.

Frequently Asked Questions
What is the difference between the HGS150A and the other HGS models?
The HGS150A is the entry-level model — smallest pillar space (330×220 mm), shortest stretching stroke (320 mm), lowest operating pressure (0.5–0.7 MPa), and the lightest machine weight (400 kg). It is specifically sized for 1-litre and smaller PET bottles. Moving to the HGS200A adds mold capacity to 200 mm and stretch to 350 mm for 1.25-litre formats; the HGS250A, 280A, and 350A step progressively to 5L, 10L, and 20L respectively. See the full HGS Series.
Does the HGS150A come with the heater, or is it sold separately?
The HGS150A blow molding machine and the HGJ infrared heater unit are separate items — both are available from Korea Ever-Power and are typically quoted together as a complete package. The HGJ-CL is the standard-neck heater (96 positions, up to 68 mm neck, 200–2,100 preforms/hour). The HGJ-B is for wide-neck jar formats (18/36 positions, up to 130 mm neck). Specify your preform neck finish and bottle format when requesting a quotation so the correct heater model is included.
What output rate can one operator sustain on the HGS150A over a full shift?
A trained operator on a standard 1-litre round PET bottle with a well-tuned HGJ-CL heater typically sustains 800–950 BPH over an 8-hour shift at comfortable pace — the 1,100 BPH figure represents peak pace during timed test runs. At 850 BPH sustained over an 8-hour shift at 85% utilisation (breaks, preform loading, occasional mold cooling), production is approximately 5,780 bottles per shift. Two operators sharing one machine can push closer to 1,050 BPH sustained.
Can the HGS150A handle different bottle designs on the same day without extended changeover?
Yes — this is one of the primary advantages of semi-automatic production. Blow mold changeover on the HGS150A typically takes 10–20 minutes including mold mounting, preform and blow rod adjustment, and first-shot inspection. Operators running 3–5 different bottle SKUs per shift is common in small-batch contract blow molding operations using the HGS series.
What compressed air supply does the HGS150A require?
The machine requires two air supplies: low-pressure working air at 0.5–0.7 MPa (for actuation, clamping, and mold opening) and high-pressure blowing air at 3.0 MPa (for bottle forming). Most industrial facilities already have 0.6–0.7 MPa utility air available. The 3.0 MPa high-pressure supply requires a dedicated high-pressure air compressor — typically a 7.5–11 kW unit for one HGS150A. Korea Ever-Power can recommend a matched compressor specification on request.
What is the minimum production volume where the HGS150A makes commercial sense?
The HGS150A is most economically suited to operations producing 5,000–500,000 bottles per month across multiple SKUs, or single-SKU operations at 5,000–50,000 units per month where a full automatic line would be oversized. Below 5,000 units per month, purchasing preformed bottles may be more practical; above 500,000 units per month on a single SKU, a fully automatic two-step line becomes more cost-effective per unit. The sample and prototype use case has no minimum — producing 100–500 samples per run is one of the most common applications.
Customer Reviews
"We use the HGS150A for sampling and small-batch production on our 3 standard 1-litre PET formats. Mold changeover takes about 15 minutes. One operator runs 850–900 BPH consistently. For our 8,000–25,000 unit monthly volumes per SKU, this machine is exactly the right scale. The HGJ-CL heater paired with it works very well for our standard-neck preforms."
HGS150A
"We are a packaging agency producing approval samples for brand clients. The HGS150A is our primary sampling machine — we run 5–8 different bottle designs per day on it. Investment was low, setup takes minutes, and our clients receive high-quality PET samples within 24 hours of mold approval. We couldn't justify a full automatic machine for this volume."
HGS150A
"Good machine for small production volumes. Note: 1,100 BPH is the peak figure — a realistic sustained rate for most operators is 800–900 BPH over a full shift. The 0.5–0.7 MPa low-pressure requirement was convenient — our existing facility air handled it without a new compressor. We needed a separate 3.0 MPa unit for blowing, which Korea Ever-Power helped us specify."
HGS150A
"We produce pharmaceutical intermediate PET bottles at 500 ml and 750 ml. The HGS150A handles both formats on the same day — 15-minute mold change, and both fit within the 150 mm mold capacity. The pneumatic linkage mechanism is simple to maintain and has been reliable over 18 months of daily operation."
HGS150A
"Started our PET bottle production business with the HGS150A. The investment was manageable as a startup — machine, heater, and two molds for our main SKUs. 12 months later we are running at 900 BPH across two 8-hour shifts, and the machine has been completely reliable. Korea Ever-Power's commissioning support was thorough — our operators were fully trained before the team left."
