EP-BPET-70V4 Kompakt 4 İstasyonlu Enjeksiyonlu Gerdirme Şişirme Kalıplama Makinesi

Ürün Genel Bakışı

O EP-BPET-70V4 4-station injection stretch blow moulding machine is Ever-Power's entry-level answer for Korean cosmetic brand incubators, pharmaceutical R&D labs, and specialty packaging contract fillers who need ISBM-grade bottle quality without the capital cost of a full production-scale line. On a 4.4 meter chassis weighing just 5.1 tons, this platform packages a genuine 4-station rotary cycle (Injection → Heating, Tail-cutting & Pre-blowing → Stretch Blow → Take-out) with 285 KN injection clamping force and 115 KN blow clamping per side. The outcome is a bench-scale footprint with commercial-grade bottle output, which until recently was simply unavailable in this price bracket.

What makes the EP-BPET-70V4 interesting for Korean operators in particular is its dual-function capability. The same machine can be set up either as an injection blow moulding machine (without the stretch rod, used for small pharmaceutical flacons and wide-mouth jars) or as a full enjeksiyon germe şişirme kalıplama makinesi using biaxial orientation for thin-wall transparent containers. Very few compact ISBM platforms offer both modes on the same chassis, and this flexibility is exactly what small-batch contract fillers in Ansan, Suwon, and Incheon need when their client mix shifts between seasonal K-beauty product launches and pharmaceutical pilot runs.

Material compatibility is surprisingly broad for a compact machine. The 45 mm screw with 24:1 L/D ratio handles PET and PETG as expected, but the independent heating architecture also accepts BPA-free Tritan, PCTG, PC, PP, SAN, PMMA, and PS. This resin flexibility makes the EP-BPET-70V4 especially attractive for Korean baby-care and premium-cosmetic brands that need to prototype in Tritan or PCTG before committing to a full-scale production machine. Field data from installed Korean and Vietnamese sites shows reject rates under 0.4% on 150 ml Tritan nursing bottles across continuous 12-hour shifts.

Ever-Power ships each EP-BPET-70V4 with tooling platens dimensioned for common 4-station mould standards, so buyers who already own compatible ASB-style small-machine moulds can often drop them directly onto the new chassis. For greenfield orders, our in-house mould shop builds the full 1-to-6 cavity tooling range, with typical lead times of 35 to 50 working days. The 4400 × 1350 × 2900 mm footprint fits comfortably through a standard Korean factory rolling door, which matters during installation far more than many buyers initially realize.

Technical Specifications & Bottle Capacity Matrix

The parameters listed below are verified against production test-run data on installed BPET-70V4 units. Before finalizing a quote, our engineering team confirms the screw size choice (45 mm standard, optional sizes available) against your specific resin IV value and target preform weight. Note that the cavity capacity table is not a hard limit but a practical recommendation — the physical platen window allows some flexibility above and below these figures for custom geometries.

Cavity Configuration & Bottle Capacity

The 4-Station Single-Step Process Explained

O 4-station injection stretch blow molding machine layout is the Goldilocks configuration in ISBM engineering. Three-station machines save footprint but combine heating and pre-blowing into a single step, which limits control over preform wall-thickness distribution. Wheel-style platforms deliver maximum throughput but price small buyers out of the market. The BPET-70V4 4-station layout sits between these extremes, dedicating each rotary position to one clearly defined task and keeping the whole cycle inside a 5.1-ton chassis.

Station 1 — Injection

Raw plastic resin feeds from the hopper into the 45 mm plasticizing screw, where it melts under controlled heater bands before being injected at 285 KN clamping force into the preform cavity. The neck finish is formed precisely here, with thread tolerance held within 0.02 mm. For Tritan and PC, our engineers typically recommend a 280 to 310 Celsius melt profile with a 15-second cavity fill followed by 8 seconds of hold pressure.

Station 2 — Heating, Tail Cutting & Pre-blowing

The turntable indexes 90 degrees, carrying the still-hot preform on its core rod into the conditioning zone. Infrared heaters re-profile the wall temperature so the body region is slightly hotter than the neck for the upcoming stretch step. A servo-driven cutter removes any sprue tail in the same position, and a low-pressure air puff initiates pre-orientation. Skipping this station (as some 3-station machines do) is the most common cause of thin corners on oval cosmetic bottles.

Station 3 — Stretch Blow

The preform arrives at the blow cavity thermally tuned and dimensionally stable. A stretch rod drops axially at servo-controlled velocity while high-pressure air between 2.0 and 3.5 MPa inflates the plastic radially against the chilled mould walls. This dual action produces biaxial molecular orientation, which is the physical reason a stretch-blown PET bottle resists drops and impact so much better than a simple blow-moulded bottle of the same weight.

Station 4 — Take-out

A robotic gripper strips each bottle off the core rod and places it upright on the exit conveyor. Because no human hand touches the preform or the finished bottle, surface defects from transfer are effectively zero. On installed Korean pharmaceutical lines, this closed-loop handling is what allows the BPET-70V4 to satisfy GMP cleanroom expectations without additional isolation enclosures. 

Dual Function: Injection Blow vs Injection Stretch Blow

One feature rarely advertised on compact ISBM machines is the ability to switch between two fundamentally different processes on the same chassis. The EP-BPET-70V4 compact 4-station ISBM machine can be configured as either an injection blow moulding (IBM) machine or a full injection stretch blow moulding (ISBM) machine. The choice is not philosophical; it is dictated entirely by bottle geometry and material performance targets.

Run as an injection blow machine, the stretch rod is removed and air pressure alone expands the preform into the final cavity shape. This mode works best for small wide-mouth pharmaceutical flacons, dropper bottles, and creme jars where the height-to-diameter ratio is low, typically under 2:1. IBM is the process of choice when the priority is dimensional accuracy of the neck finish rather than molecular orientation of the body. Operators report cycle times around 12 to 15 seconds on 5 ml eyedrop vials in 4-cavity IBM configuration.

Switched to full stretch-blow mode, the same machine becomes a genuine enjeksiyon germe şişirme kalıplama makinesi producing tall, slender cosmetic serum bottles, water tumblers, and baby feeding bottles. The stretch rod drives axial elongation, air pressure drives radial inflation, and the resulting biaxial orientation lifts top-load strength by roughly 30 percent and oxygen barrier by up to 20 percent versus plain injection blow. For the same final wall thickness, stretch-blown bottles can be lightweighted by 10 to 15 percent without losing rigidity. This lightweighting is the single largest cost-saving lever in packaging, and it is one reason Korean beverage and cosmetic brands specify ISBM for any container taller than 100 mm.

Swapping between the two modes on the BPET-70V4 takes a trained technician roughly 45 minutes, mostly spent on the stretch rod assembly and the associated servo cam profile in the PLC. For contract fillers who handle a weekly mix of product types, this mode-switching capability is worth more than it appears on the spec sheet.

Material Compatibility & Application Scenarios

The 44 KW barrel heating and independent mould temperature circuits give the compact ISBM machine a broader resin window than its size suggests. Below are the four application scenarios where Korean and East Asian customers have deployed the BPET-70V4 successfully over the past three years.

Small-Batch Cosmetic & K-Beauty Sample Bottles

Korean cosmetic brands launch dozens of new SKUs per year, and each launch demands pristine 15 ml to 50 ml PETG sample bottles for gift-with-purchase and influencer kits. The BPET-70V4 running a 4-cavity mould delivers roughly 1,400 bottles per hour at 30 ml format, which matches the typical short-run quantity of 20,000 to 50,000 units. Because the machine is a true small PET bottle blowing machine rather than an oversized line, the set-up and tear-down time is low enough to justify a 1-week production campaign.

Pharmaceutical R&D & Pilot-Scale Production

For drug developers running clinical trial batches, the BPET-70V4 offers a GMP-clean bottle production path without committing to a full production machine. Single or 2-cavity configurations produce 50 ml to 500 ml pharmaceutical syrup bottles, oral-suspension vials, and saline flacons. The enclosed melt-to-bottle cycle eliminates contamination risk, and reject rates stay under 0.3 percent when the machine is paired with a properly sized chiller and a resin pre-dryer.

BPA-Free Tritan Baby Feeding Bottles

Tritan processes within a narrow thermal window, and smaller machines often struggle to hold melt temperature stable during extended shifts. The BPET-70V4 44 KW barrel heating delivers measured thermal stability within 2 Celsius of setpoint over 12-hour runs, which shows up directly in the optical clarity of the final bottle. A 3 or 4-cavity mould producing 150 to 240 ml baby bottles is the most common configuration, and buyers consistently report near-zero yellowing across 100,000+ unit campaigns.

Pilot-Scale Beverage & Specialty Containers

Small Korean craft beverage brands — kombucha, cold-brew coffee, specialty juice — often need to test a new bottle design before committing to a production volume that would justify a large four-station machine. The BPET-70V4 with a 3-cavity 1000 ml mould delivers enough throughput for a 500-case proof-of-concept run, and if the product succeeds, the same moulds can be rolled onto a larger Ever-Power line like the HGY200-V4 for scale-up.

Core Advantages at a Glance

The following six strengths are what Korean and East Asian buyers consistently cite when choosing the compact EP-BPET-70V4 over larger or more generic 4-station ISBM platforms.

When BPET-70V4 Is the Right Size — Comparison with Larger HGY Series

Ever-Power offers six distinct 4-station platforms ranging from this 5.1-ton BPET-70V4 up to the 28-ton HGY650-V4. Picking the correct tonnage and injection capacity for your production volume is the single biggest factor in total cost of ownership over the next decade. The table below summarizes the practical trade-offs. The comparison is offered for selection guidance only and does not imply any performance deficiency in the larger models, each of which is optimized for its own production scale.

Buyers who land on the BPET-70V4 typically fit one of three profiles: a K-beauty incubator running short production campaigns, a pharmaceutical R&D group doing clinical-trial batch work, or a contract filler who needs an agile secondary machine alongside a larger primary line. For higher-volume continuous production, the HGY150-V4 offers more cavity capacity, and the HGY250-V4 steps up to heavy-wall 300 KN injection clamping.

Selection Guide — What to Confirm Before Ordering

A correctly scoped BPET-70V4 order ships in 60 working days and commissions in a week. A poorly scoped order can double that timeline with avoidable rework. Please confirm the following items with your project engineer before we finalize a quote.

• Annual production volume per bottle SKU. Below roughly 500,000 units per year, the BPET-70V4 is the economical choice. Above that threshold, a larger HGY platform usually pays back faster.
• Bottle geometry and neck finish — share a 3D STEP file or detailed drawing including body diameter, overall height, neck thread standard (for example 18-415, 24-410, 28-400).
• Preform weight range you expect. The 340 cm³ theoretical injection capacity covers most small and mid-size bottles, but we verify each project against cavity count.
• Resin grade and supplier — critical for Tritan, PCTG, and PPSU where processing windows are narrow. Include the data sheet with your inquiry.
• Mode preference — are you using the machine primarily as an injection blow moulding machine (wide-mouth, short bottles) or as a full injection stretch blow moulding machine (tall, slender bottles)? Tooling is sized differently for each.
• Voltage and frequency — Korean 380 V / 60 Hz is standard; we configure 400 V / 50 Hz and other regional variants for export units.
• Compressed air supply — a minimum of 3.5 MPa high-pressure at 2 cubic meters per minute for blowing, plus low-pressure feed for pneumatic controls.
• Chiller and cooling tower capacity — 80 L/min chilled water at 12 Celsius, plus 200 L/min cooling tower water for hydraulic oil cooling.
• Installation footprint — confirm at least 5.5 × 2.5 meters of clear floor space plus overhead crane access of 4 meters.
• Existing mould inventory — if you have compatible 4-station ISBM tooling from another supplier, send us the base drawings and we will verify drop-in compatibility.

Related Products & Matching Components

The BPET-70V4 reaches its rated cycle time only when the auxiliary equipment around it is sized correctly. The components below are what we specify for every compact 4-station installation, and most can be sourced from our partner suppliers to keep the accountability under one roof.

• Oil-free screw air compressor rated for 3.5 MPa at 2 cubic meters per minute. Clean air is the single largest factor in bottle clarity on transparent cosmetic lines, and Class 0 oil-free certification is mandatory for pharmaceutical and food-contact work. Our matched unit specifications are available through our oil-free screw compressor partner.
• Water chiller and cooling tower pair delivering 80 L/min chilled water at 12 Celsius for the mould cavity circuit, plus 200 L/min cooling tower water for hydraulic oil cooling. A 10-ton chiller is adequate for most BPET-70V4 installations running 4-cavity or smaller tooling.
• Resin dryer and dew-point-monitored feeder — critical for PET and PC, where even a 0.1 percent moisture excess causes hydrolysis and visible silver streaks. We recommend a 100 kg-capacity hopper dryer with integrated dew-point monitoring for a typical BPET-70V4 line.
• Precision transmission shaft and drive components — our main indexing drive uses hardened alloy steel that withstands the servo-motor start-stop torque without elongation. Replacement shafts and bearings are available through our precision drive shaft supplier for sites needing fast local replenishment.
• Mould temperature controller for the blow cavity, keeping cavity wall temperature between 10 and 18 Celsius depending on the resin and wall thickness. For thick-wall PCTG jars, two independent zone controllers work better than a single-circuit unit.
• Custom ISBM moulds — our in-house tool shop produces preform cavities, core rod assemblies, and blow moulds for the BPET-70V4 with typical lead times of 35 to 50 working days. Moulds are built on German 5-axis CNC equipment with trial-molding validation before shipment.
• Robotic takeout conveyor and optional vision inspection for high-value pharmaceutical and cosmetic runs where zero-defect delivery is expected. Vision systems tag out-of-spec parts before they reach the filling line.
