1. Product Overview<\/h2>\n

The HGS Series Semi-Automatic PET Blow Molding Machines<\/strong> comprise 6 models \u2014 HGS-1 through HGS-6 \u2014 offering 1 to 6 cavities and maximum container volumes from 600 ml (HGS-1) to 3,600 ml (HGS-6). The semi-automatic process uses manual operator loading of pre-heated preforms into the blow station, with the machine autonomously performing mold closing, stretch-rod extension, pre-blowing, high-pressure blowing, cooling, and mold opening. The operator removes finished bottles and loads the next preform batch.<\/p>\n

This operating mode eliminates the most capital-intensive elements of fully automatic platforms \u2014 the multi-zone NIR oven, preform orientation bowl, automatic conveyor system, and preform sorter \u2014 reducing machine cost and footprint substantially. A separate infrared preform heating oven (supplied as part of the HGS package or sourced independently) pre-conditions preforms before the operator loads them. The trade-off is lower throughput and higher labour cost per bottle versus fully automatic machines \u2014 an acceptable exchange for the applications this series targets.<\/p>\n

The HGS series is the practical choice for four distinct use cases: product development sampling<\/strong> (producing a small quantity of accurate prototype bottles from a new mold before committing to full automatic production investment); entry-level commercial production<\/strong> (regional beverage or food brands with modest initial volumes that do not justify full-automatic CapEx); multi-format flexibility operations<\/strong> (producers running many different bottle types in small quantities where fast mold changes and low per-mold tooling cost outweigh throughput); and developing-market initial investment<\/strong> where operational experience, market validation, and capital preservation are priorities before scaling to fully automatic platforms.<\/p>\n

2. Working Principle<\/h2>\n

The HGS series uses the two-step stretch blow molding process<\/strong> with manual preform loading. In step one, PET preforms are heated to stretch temperature (typically 100\u2013115\u00b0C) in a separate infrared oven unit \u2014 either the matched HGS infrared oven or a compatible external oven. Operator loads the heated preforms neck-up into the machine’s blow station \u2014 one preform per cavity. The machine then takes over for all remaining production steps automatically.<\/p>\n

\n
\n

Step 1 \u2014 Preheat (Manual)<\/p>\n

Operator loads preforms into infrared oven unit and heats to target stretch temperature.<\/p>\n<\/div>\n

\n

Step 2 \u2014 Load (Manual)<\/p>\n

Operator places heated preforms neck-up into the blow station \u2014 one per cavity.<\/p>\n<\/div>\n

\n

Step 3 \u2014 Clamp (Auto)<\/p>\n

Machine closes mold halves around all preforms simultaneously. Operator steps back.<\/p>\n<\/div>\n

\n

Step 4 \u2014 Stretch & Blow (Auto)<\/p>\n

Servo stretch rods extend axially; pre-blow at 7 kg\/cm\u00b2 then high-pressure blow at 30 kg\/cm\u00b2 drives PET against cooled mold wall.<\/p>\n<\/div>\n

\n

Step 5 \u2014 Cool & Open (Auto)<\/p>\n

Mold-wall cooling solidifies bottle geometry. Machine opens mold and signals operator for unloading.<\/p>\n<\/div>\n

\n

Step 6 \u2014 Unload (Manual)<\/p>\n

Operator removes finished bottles and loads the next preform batch to restart the cycle.<\/p>\n<\/div>\n<\/div>\n

The biaxial molecular orientation achieved during simultaneous axial (stretch rod) and radial (blow air) stretching is identical to that produced by fully automatic machines \u2014 finished bottle mechanical properties, clarity, barrier performance, and weight efficiency are equivalent. The only production difference is cycle time and operator involvement, which determine the throughput range of 400\u20131,800 bph depending on model.<\/p>\n<\/div>\n

3. Core Advantages<\/h2>\n
\n
\n
\ud83d\udcb0<\/div>\n

Low CapEx \u2014 Lowest Entry Cost into PET<\/h3>\n

Eliminating the automated oven, conveyor, and preform feed system reduces machine cost dramatically versus fully automatic platforms. For brands and producers where initial production volume does not justify the CapEx of a full-automatic machine, the HGS series provides a commercially viable entry point \u2014 with a clear upgrade path to fully automatic ES or AS series machines as volume grows.<\/p>\n<\/div>\n

\n
\ud83d\udd04<\/div>\n

Fast Mold Changeover \u2014 Multi-Format Flexibility<\/h3>\n

Without a fixed preform handling system to reconfigure, mold changes on the HGS series take 15\u201325 minutes versus 45\u201390 minutes on full-automatic machines. For producers running 5\u201315 different bottle formats in small quantities, this rapid changeover enables same-day multi-format production that would be uneconomical on dedicated full-automatic lines.<\/p>\n<\/div>\n

\n
\ud83d\udcc8<\/div>\n

Scalable 1 to 6 Cavities<\/h3>\n

Six models covering 400 bph (HGS-1, single cavity) to 1,800 bph (HGS-6, six cavities) match every entry-level and small-batch production volume. A producer can start on HGS-1 for sampling and graduate to HGS-4 or HGS-6 for commercial production without changing machine architecture, tooling standards, or operator training.<\/p>\n<\/div>\n

\n
\ud83d\udd2c<\/div>\n

Full-Quality Bottles \u2014 Same Biaxial Orientation<\/h3>\n

Bottles produced on HGS series machines have identical biaxial molecular orientation, clarity, barrier performance, and mechanical properties to those from fully automatic machines \u2014 the stretch-blow process is unchanged. This makes HGS-produced bottles fully suitable for commercial filling, labelling, and distribution without any quality compromise versus automatic-machine output.<\/p>\n<\/div>\n

\n
\ud83d\udee0<\/div>\n

Compact Footprint \u2014 Minimal Infrastructure<\/h3>\n

The HGS-1 occupies just 1.2 m \u00d7 1.0 m floor area \u2014 the smallest PET blow molding machine footprint available. Even the HGS-6 at 4.2 m \u00d7 1.0 m fits within production spaces that cannot accommodate full-automatic machines. Low compressed-air consumption versus automatic machines also reduces utility infrastructure requirements.<\/p>\n<\/div>\n

\n
\ud83d\udc68\u200d\ud83d\udd27<\/div>\n

Simple Operation \u2014 Minimal Training<\/h3>\n

The semi-automatic process requires minimal operator training compared with full-automatic machine setup and maintenance. Basic operators can be trained to load preforms and monitor bottle quality within a single shift. This is a meaningful advantage in markets or facilities where skilled blow molding technicians are scarce or expensive.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\u26a1 Compressed Air Requirement:<\/strong> All models require low-pressure air at 7 kg\/cm\u00b2 and high-pressure blowing air at 30 kg\/cm\u00b2. For food-contact bottle production, an oil-free compressor is recommended to prevent hydrocarbon contamination of bottle interiors. Read our technical guide: why PET stretch blow molding demands high-pressure oil-free compressors<\/a> \u2014 we supply matched oil-free compressor packages as part of our turnkey solution.<\/div>\n<\/div>\n

5. Structure & Material Engineering<\/h2>\n
\n
\n

\ud83d\udee0 Machine Frame<\/h3>\n

Welded steel frame, stress-relieved, with CNC-machined guide rails and bearing surfaces. The compact 1,000 mm-wide constant footprint across all 6 models means only the machine length extends with cavity count \u2014 simplifying factory floor planning. Frame height is constant at 1,600 mm, compatible with standard workshop doorways for easy installation without overhead crane access.<\/p>\n

\u2699 Blow Station<\/h3>\n

Toggle-link pneumatic mold clamping \u2014 appropriate for the semi-automatic cycle rate \u2014 with servo stretch rods providing \u00b10.1 mm axial positioning accuracy. The 30 kg\/cm\u00b2 blowing pressure (lower than the 35 kg\/cm\u00b2 used on full-automatic platforms) is optimised for the container volume range of this series and reduces compressor operating cost per bottle.<\/p>\n<\/div>\n

\n

\ud83d\udd13 Blow Mold Tooling<\/h3>\n

HGS-series blow molds use the same aluminium alloy and conformal-cooling-channel standard as full-automatic machine molds \u2014 bottle quality and dimensional accuracy are equivalent. Mold cost for semi-automatic platforms is lower than for automatic machines (no preform mandrel tooling required, simpler oven interface). Changeover between bottle formats requires mold substitution only \u2014 15\u201325 minutes versus 45\u201390 minutes on full-automatic lines \u2014 making multi-format small-batch production economically viable.<\/p>\n

\ud83c\udf21 Separate Infrared Oven<\/h3>\n

The HGS series is supplied with (or compatible with) a matched infrared preform heating oven. The oven provides adjustable zone temperature control for different preform wall profiles and materials. Preform batch size in the oven matches cavity count \u2014 operators develop a workflow rhythm that keeps the oven output synchronised with the machine cycle time. Oven specifications are matched to the HGS model at the time of order.<\/p>\n<\/div>\n

\n

\ud83d\udcf1 PLC Control<\/h3>\n

Siemens or Mitsubishi PLC with colour HMI touchscreen. Stretch rod position, blow pressure, blow duration, and cooling time are all PLC-controlled and stored per bottle format. Format recipe recall eliminates manual parameter setting at mold change \u2014 operators simply select the recipe for the new bottle format and begin production immediately after mold substitution.<\/p>\n

\ud83d\udcc8 Scalable from HGS-1 to HGS-6<\/h3>\n

All six models share common spare parts for the blow station, PLC, and pneumatic system \u2014 simplifying maintenance inventory for operators running multiple HGS models. Mold tooling designed for a given neck and container envelope is interchangeable across HGS models of different cavity counts, reducing retooling cost when scaling from a smaller to a larger model.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

6. Semi-Automatic vs. Fully Automatic \u2014 Which Is Right for You?<\/h2>\n

This is the most common question buyers ask when considering the HGS series. The answer depends on your production volume, product variety, investment stage, and operational environment. Neither platform is universally superior \u2014 each is optimal for specific conditions.<\/p>\n

7. Typical Application Scenarios<\/h2>\n
\n
\n
\n

\ud83d\udd2c Product Development & Bottle Sampling<\/h3>\n<\/div>\n
Before ordering a full-automatic machine and molds for a new bottle design, brands and packaging converters use the HGS-1 (500 bph) to produce a small quantity of accurate prototype bottles from a new blow mold. This validates the bottle geometry, wall weight, top-load performance, and filling-line compatibility at a fraction of the cost of validating on a full-automatic production line. Most major PET bottle brands globally use semi-automatic machines at this stage.<\/div>\n<\/div>\n
\n
\n

\ud83c\udf7a Entry-Level Regional Beverage Production<\/h3>\n<\/div>\n
Regional mineral water brands, craft soft drink producers, and artisan juice companies with daily production needs of 3,000\u201315,000 bottles are well served by HGS-2 through HGS-4 (750\u20131,200 bph). The lower CapEx relative to fully automatic platforms allows these brands to own their bottle production from launch without the volume commitment required to justify automatic machine investment \u2014 improving margin and supply-chain independence from Day 1.<\/div>\n<\/div>\n
\n
\n

\ud83c\udfed Multi-Format Small-Batch Packaging<\/h3>\n<\/div>\n
Contract packaging operations, promotional packaging producers, and specialty food brands running 5\u201320 different bottle formats in small quantities per SKU use the HGS series for its 15\u201325 minute mold changeover time. Running 8 different bottle formats in a single shift \u2014 each at 200\u2013400 units \u2014 is commercially viable on an HGS platform but operationally impossible on a full-automatic machine where changeover cost alone eliminates the economics of short runs.<\/div>\n<\/div>\n
\n
\n

\ud83c\udf0d Developing-Market Initial Investment<\/h3>\n<\/div>\n
In markets where PET bottle production is emerging and volume projections carry uncertainty, the HGS series enables producers to enter the market with verified technology and a clear upgrade path, without committing to full-automatic CapEx that may exceed early-stage cash flow. As volume grows, HGS machines can be retained for product development while full-automatic ES series machines are added for commercial production.<\/div>\n<\/div>\n
\n
\n

\ud83c\udf3b Specialty Food & Condiment Bottles<\/h3>\n<\/div>\n
Artisan condiment, sauce, and specialty food brands often produce seasonal or limited-edition bottle formats with annual volumes of 20,000\u2013100,000 bottles per SKU. The HGS-3 or HGS-4 (1,000\u20131,200 bph) can produce a full annual SKU in 20\u2013100 hours of production \u2014 a compelling argument for in-house bottle production versus purchasing from a converter at premium prices.<\/div>\n<\/div>\n
\n
\n

\ud83d\udcc8 Training & Technology Transfer<\/h3>\n<\/div>\n
Technical schools, packaging technology institutes, and brand R&D centres use HGS series machines as hands-on training platforms \u2014 the manual preform loading step forces operators to directly experience the relationship between preform temperature, stretch behaviour, and bottle outcome in a way that fully automatic machine operation does not. This makes HGS machines valuable for developing the in-house technical capability required before operating larger automatic platforms.<\/div>\n<\/div>\n<\/div>\n<\/div>\n

9. Frequently Asked Questions<\/h2>\n
\n
Q1: Are semi-automatic machines able to produce commercially acceptable bottle quality?<\/strong><\/div>\n
Yes \u2014 without qualification. The biaxial orientation, mechanical properties, clarity, and barrier performance of bottles produced on HGS semi-automatic machines are identical to those from fully automatic platforms, because the stretch-blow cycle is performed by the same mechanism. The only production difference is manual preform loading versus automated feeding. HGS-produced bottles pass the same filling-line, drop-test, and top-load validation criteria as automatic-machine bottles.<\/div>\n<\/div>\n
\n
Q2: What separate equipment is needed alongside the HGS machine?<\/strong><\/div>\n
The HGS machine handles clamping, stretching, blowing, cooling, and mold opening \u2014 all automatically. You additionally need: (1) an infrared preform heating oven (supplied as part of the HGS package or sourced separately) to pre-heat preforms before manual loading; (2) a chiller to supply 8\u201310\u00b0C cooling water to the mold; (3) a compressor providing low-pressure air at 7 kg\/cm\u00b2 and high-pressure air at 30 kg\/cm\u00b2. We supply all auxiliary equipment as part of a complete HGS package on request.<\/div>\n<\/div>\n
\n
Q3: How many operators are required per HGS machine?<\/strong><\/div>\n
One operator per machine \u2014 and in many cases, one operator can manage two HGS machines if the preform heating time roughly matches the machine blow-and-cool cycle time. The operator’s role is: load preforms into the oven; transfer heated preforms to the blow station; initiate the cycle; remove finished bottles while the machine completes its automatic sequence; reload preforms into the oven. An experienced operator typically establishes a rhythm within the first shift that maximises throughput while maintaining preform temperature consistency.<\/div>\n<\/div>\n
\n
Q4: Can HGS-series molds be used on full-automatic ES-series machines later?<\/strong><\/div>\n
Generally no \u2014 full-automatic machine molds interface with a different preform mandrel and mold-carrier system than semi-automatic machine molds. However, the bottle design validated on an HGS machine can be reproduced in a full-automatic machine mold without redesign \u2014 only the mold mounting interface changes. This means that the product development investment (bottle design, preform design, filling-line validation) made on the HGS platform transfers fully to the full-automatic platform when you scale up.<\/div>\n<\/div>\n
\n
Q5: What bottle neck finishes and preforms are compatible?<\/strong><\/div>\n
All HGS models are designed for a maximum neck diameter of 38 mm \u2014 covering the standard beverage neck finishes PCO 1881 (28 mm), PCO 1810 (28 mm), and up to 38 mm. Custom neck finishes within the 38 mm maximum are accommodated by the appropriate blow mold and preform combination. Preforms must be sourced to match the specific bottle design and neck finish \u2014 we can advise on preform specification at the mold design stage.<\/div>\n<\/div>\n
\n
Q6: How quickly can I change between different bottle formats?<\/strong><\/div>\n
Mold changeover on HGS machines takes 15\u201325 minutes for an experienced operator \u2014 significantly faster than 45\u201390 minutes on full-automatic machines because there is no preform handling system to reconfigure. After mold substitution, select the new bottle format recipe on the HMI and run 3\u20135 warm-up cycles to stabilise the blow station before resuming full-rate production. Operators running 5\u20138 different formats in a shift typically achieve 20-minute average changeover times after the first week of operation.<\/div>\n<\/div>\n
\n
Q7: Is there an upgrade path from HGS to fully automatic machines?<\/strong><\/div>\n
Yes \u2014 and this is a common growth path we support. When your production volume justifies the transition to a full-automatic ES-series machine, the bottle design, preform specification, and filling-line process validated on the HGS platform transfer directly. We advise retaining the HGS machine for product development and new bottle trials while full-automatic machines handle commercial production \u2014 maximising the utilisation of both platforms and eliminating the risk of using valuable automatic machine time for experimental production.<\/div>\n<\/div>\n
\n
Q8: What is the production lead time from order to delivery?<\/strong><\/div>\n
HGS series machines are produced within 30\u201345 working days from deposit receipt \u2014 shorter than full-automatic machines due to simpler machine architecture. Blow molds for confirmed 3D bottle designs are delivered in 20\u201330 working days. The complete HGS package including machine, oven, chiller, and compressor can typically be installed and producing saleable bottles within 60 working days of order placement. On-site commissioning typically requires 2\u20133 working days.<\/div>\n<\/div>\n
\n
Q9: What certifications do the HGS machines carry?<\/strong><\/div>\n
All HGS series machines are CE-marked. Electrical component verification certificates are available. For food-contact bottle applications, documentation confirming the machine’s no-hydraulic-fluid architecture is available. Country-specific certifications can be supported subject to additional testing requirements at the destination market.<\/div>\n<\/div>\n
\n
Q10: Can HGS machines produce food-contact or pharmaceutical-contact bottles?<\/strong><\/div>\n
Yes. The bottle produced is a PET container whose food-contact compliance is determined by the preform resin grade, not by the blow molding machine. Using food-grade PET preforms on the HGS series produces containers meeting FDA, EU Regulation 10\/2011, and equivalent food-contact standards. For pharmaceutical packaging, an oil-free compressor at the high-pressure blowing point is required \u2014 we supply matched oil-free compressor packages as part of the HGS system on request.<\/div>\n<\/div>\n<\/div>\n
