EP-HGYS280-V6 六工位注塑拉伸吹塑成型机

产品概述

这 EP-HGYS280-V6 6-station injection stretch blow moulding machine represents the scale-up answer for Korean manufacturers who have outgrown their 4-station lines but are not yet ready for the footprint and capital of a rotary wheel system. Built on the proven Ever-Power chassis, this six-station platform integrates two parallel injection units on a single rotating turntable, effectively doubling the throughput of conventional single-injection designs while sharing the same melt-plasticizing, clamping, and auxiliary systems. For a 250 ml pharmaceutical bottle, field data from installed sites in Incheon and Busan shows the EP-HGYS280-V6 reaching 3,600 bottles per hour on an 8-cavity mould, a figure that previously required two separate HGY150-V4 machines to match.

What sets the HGYS280-V6 apart is not simply the station count, but the way each of the six indexed positions has been optimized for its specific job. Injection Station A and Injection Station B run synchronized 180-degree cycles, so while one cavity is being filled the other is cooling, eliminating the idle time that plagues simpler layouts. A dedicated thermal conditioning station then profiles the preform temperature before the stretch-blow station takes over, and a generous take-out station allows for robot extraction without the rushed handling that causes scuffing on high-clarity cosmetic bottles. The result is a twin-injection ISBM machine that behaves less like two smaller machines stapled together and more like a single coherent production cell.

Material flexibility is another reason this six-station ISBM machine has found a home in Korean specialty packaging plants. The 10 KW nano-far-infrared heating ring handles PET and PETG as expected, but the machine is equally comfortable with high-temperature resins such as PP, PC, PPSU, and Tritan, which are increasingly specified for BPA-free baby bottles and glass-replacement cosmetic jars. Because the preform never leaves the machine, there is no reheating cycle, no storage contamination, and no handling-induced haze. Factories that previously shipped preforms from one facility for re-blowing at another can collapse the entire workflow into one enclosed cell, reducing floor space by roughly 35% and eliminating an entire warehouse bay of preform buffer stock.

Ever-Power ships the EP-HGYS280-V6 with full drop-in compatibility for Japanese ASB-style 12M tooling, which matters because many established Korean operators have a decade of mould inventory they would prefer not to scrap. Upgrading to a new one-step injection stretch blow molding platform without rebuilding the mould library is a genuine cost saver, and our engineering team will verify platen layouts and core-rod pitches before shipment. For greenfield buyers, the standard HGYS280-V6 configuration covers bottle diameters up to 120 mm and volumes up to 2500 ml on single-cavity tooling, dropping down to 20 ml vials on 10-cavity layouts.

How the 6-Station Twin-Injection Process Works

Understanding why a 6-station ISBM machine outpaces a 4-station design is less about having more stations and more about how the cycle time breaks down across them. On a traditional 4-station layout, the injection station is the slowest step because plastication and cavity filling simply take longer than blowing or ejection. The HGYS280-V6 solves this bottleneck by splitting the injection work across two mirrored stations, so the turntable never has to wait for a single injection cylinder to catch up. Below is how one full rotation unfolds on the HGYS280-V6 6-station injection stretch blow moulding machine.

Injection Station A

The first plasticizing unit meters a precise melt shot through a hot runner into one half of the preform mould array. Gate pressures are logged in real time by the Inovance PLC, and any deviation above 3% triggers an automatic alarm. The neck finish is fully formed and cooled to a tolerance of roughly 0.01 mm at this stage, which guarantees leak-proof sealing downstream.

Injection Station B

While Station A is filling, the preform that was already injected one rotation earlier on Station B is now completing its residence time. A second plasticizing unit, running on the same servo pump bank, injects a matching shot. Because both stations share auxiliary services but operate on offset timing, the machine effectively finishes one full preform set every half-cycle, which is the origin of the doubled throughput.

Temperature Conditioning & Tail Cutting

The core rod carrying the hot preform rotates onto the conditioning station, where infrared zones gently re-profile the wall temperature for optimum axial stretch. A servo-driven cutter trims the sprue tail in the same indexed position, eliminating a separate offline step. This combined function is what allows the HGYS280-V6 to keep an overall footprint of just 5.9 meters.

Stretch Blow Station

With the preform thermally tuned, the stretch rod drives down at a servo-controlled velocity, and high-pressure air in the 2.0 to 3.5 MPa range inflates the plastic against the chilled mould walls. Biaxial molecular orientation happens in this instant, giving the finished bottle its characteristic clarity and drop resistance. For thick-wall cosmetic jars, our engineers recommend a two-stage pre-blow profile to prevent pearlescence near the heel.

Take-out Station

Finished containers are stripped from the core rod onto a conveyor in upright orientation. Because handling is entirely robotic and the bottle never touches a human hand, surface defects from transfer are essentially non-existent. Optional camera-based vision inspection can be mounted at this exit to tag any out-of-spec parts before they reach the filling line.

Core Advantages at a Glance

The following six strengths are what buyers consistently cite when choosing the EP-HGYS280-V6 over competing 4-station and wheel-style platforms. Each has been validated in production environments across Korea, Vietnam, and Thailand over the past three years.

 

Typical Application Scenarios

Over the past five years the EP-HGYS280-V6 has been commissioned on production lines spanning four distinct sectors. Each scenario below reflects actual customer deployments, not theoretical capability.

Pharmaceutical Vials & Eye-Drop Bottles

Korean pharma contract manufacturers routinely run 10 to 15 ml eye-drop bottles and 100 ml oral suspension vials on the HGYS280-V6. The enclosed melt-to-bottle path satisfies GMP cleanroom requirements because no operator touches the preform between injection and blow. On a 9-cavity mould configuration, the machine produces roughly 4,800 vials per hour of 30 ml format, and the neck thread tolerance stays within 0.05 mm across the entire run.

Personal Care & Cosmetic Packaging

K-beauty brands demand glass-clarity finishes on PETG and PCTG serum bottles, and the HGYS280-V6 delivers that consistently because the preform never leaves the enclosed mould environment. Heavy-wall jars up to 4 mm thickness run well on 4 or 6 cavity layouts, and thanks to the conditioning station profile control, oval and flat-sided shapes keep even wall distribution without the thinning that plagues single-step 3-station designs.

Mid-Volume Beverage & Dairy Bottles

For 250 ml fruit-juice and yogurt-drink bottles, a 6-cavity configuration hits roughly 3,200 bottles per hour. This matches the throughput needs of small-to-mid regional beverage bottlers in Gwangju and Ansan who want to keep PET production in-house instead of buying preforms and re-blowing them on a separate machine. The integrated line reduces preform inventory by over 95 percent because nothing is stockpiled.

Specialty Wide-Mouth Food Jars

Sauce, honey, and health-food jars with neck diameters up to 70 mm fit within the HGYS280-V6 envelope when running a 2-cavity mould. The 200 KN blow clamping force per side is sufficient to hold the larger projected area against blow pressure, and the twin-injection design keeps cycle time competitive even with the larger shot weights that wide-mouth preforms require.

Material Compatibility & Preform Design Guidance

One of the lesser-advertised strengths of the HGYS280-V6 is how broad its resin window is. The nano-far-infrared heating ring accepts temperature setpoints from 230 up to 305 degrees Celsius, which brings a long list of engineering plastics into range. Below are the materials most frequently processed on Korean and Southeast Asian installations.

• 宠物 — the default for water, juice, and mid-volume cosmetic bottles. Target melt temperature around 275 to 285 Celsius, axial stretch ratio of 2.5 to 3.0, hoop stretch ratio up to 4.5.
• PETG — amorphous copolymer preferred for clear cosmetic jars. Runs colder than PET at 225 to 245 Celsius, gives exceptional surface gloss but is more sensitive to over-stretch whitening.
• PP — chosen for translucent baby bottles and some pharmaceutical flacons. Melt temperature 200 to 230 Celsius, lower blow pressures in the 1.5 to 2.5 MPa band.
• 个人电脑 and PCTG — used for premium heavy-wall jars and reusable sports bottles. Requires dry preform stock at under 0.02 percent moisture to avoid silver streaking.
• PPSU and 特里坦 — the BPA-free high-temperature family. Processing temperatures of 310 to 340 Celsius for PPSU, slightly less for Tritan. These resins are the reason pharmaceutical and baby-care buyers look at the HGYS280-V6 in the first place.
• PS and ABS — supported for specialty craft packaging, usually in small production volumes where 1 or 2 cavity tooling suits the application.
• PLA — biodegradable option for eco-brands, requires tight moisture control and slower injection profiles, but the HGYS280-V6 servo pump handles the reduced back-pressure well.

Preform design on a 6-station injection stretch blow moulding machine needs to account for the thermal residence time on the conditioning station. If you come to Ever-Power with a finished bottle drawing, our engineering team will run a stretch-ratio simulation and recommend preform wall thickness, neck finish orientation, and gate placement before any steel is cut. This avoids the costly trial-and-error loop that typically eats up the first two weeks of a new project.

HGYS280-V6 vs HGY150-V4 vs HGY250-V4 — Which Fits Your Plant?

Because all three machines share the same injection clamping class and accept similar tooling, Korean customers often ask which platform is the economical choice for their specific volume. The table below summarizes the practical trade-offs. This comparison is meant as a selection aid only and does not imply any criticism of the single-injection 4-station layout, which remains the right choice for smaller batch-size operations.

Buyers who land on the HGYS280-V6 are almost always in the scaling phase. They have proven a product on a smaller HGY150-V4 or on a contracted preform line, and are now committing to in-house mid-volume production. For factories that primarily need higher clamping tonnage rather than higher cycle rates, the HGY250-V4 remains the right choice.

Selection Guide — What to Confirm Before Ordering

A well-scoped order cuts the commissioning time in half. Before our engineering team can quote the EP-HGYS280-V6 accurately, please confirm the following data points. Most of these can be lifted directly from an existing bottle drawing or a sample finished container.

• Bottle geometry — body diameter, overall height, neck finish standard (e.g. 28-410, 24-415, PCO 1881), and any asymmetric or oval shape constraints.
• Target finished weight and fill volume, plus any target lightweighting percentage versus the current container.
• Resin grade and supplier — IV value for PET, melt flow index for PP, moisture specification. If you are switching to rPET, please share the flake source and contamination spec.
• Preform weight range expected per cavity, which determines whether the 50 mm screw is adequate or whether a 55 / 60 mm option is required.
• Cavity count target, tied to your yearly production volume. Our engineers run a payback calculation to recommend the most economical cavitation.
• Voltage and frequency — Korean 380 V / 60 Hz is standard, but we configure for 400 V / 50 Hz and other regional variants on request.
• Compressed air supply — minimum 3.5 MPa high-pressure at around 3 cubic meters per minute for blowing, separate low-pressure feed for pneumatic controls.
• Chiller and cooling tower capacity — target chilled water at 12 Celsius, cooling tower water up to 30 Celsius return.
• Installation footprint — confirm 7 × 4 meters of clear floor space plus overhead crane access of at least 5 meters.
• Mould drop-in compatibility — if you already own ASB-12M-style tooling, send us the mould base drawings and we will verify platen bolt patterns and ejector pitch.
