Descripci\u00f3n general del producto<\/h2>\n

El EP-BPET-125V4 heavy-duty 4-station injection stretch blow moulding machine<\/strong> is the step-up choice for Korean manufacturers whose production plans cannot be served by a compact 5-ton platform. With 685 KN of injection clamping force, 286 KN of blow clamping per side, and a full 60 mm plasticizing screw delivering 480 cubic centimeters of theoretical injection volume, the BPET-125V4 covers the exact corner of the ISBM market where bulk water gallons, wide-mouth food jars, and high-temperature baby care bottles are produced. The 11.6-ton welded steel chassis gives it the rigidity to run 12-cavity tooling without flexing at the platens, which is what separates serious production-scale machines from scaled-up prototyping units.<\/p>\n

Factory buyers in Ulsan, Gimhae, and Busan typically evaluate the BPET-125V4<\/strong> against two competing scenarios. One is buying two smaller compact machines to split the workload between large and small bottles \u2014 an approach that ends up costing more in floor space, operator headcount, and maintenance contracts. The other is buying an imported Japanese or German platform in the same tonnage class, which in 2025 still commands a 45 to 55 percent price premium over the Ever-Power equivalent while offering very similar real-world output. For operators who care about throughput per square meter and capital payback, the BPET-125V4 has become the default Korean answer over the past three years.<\/p>\n

\"Moldeo<\/p>\n

Material range is where this heavy-duty ISBM machine<\/strong> genuinely extends its reach. The 60 mm screw with 24:1 L\/D ratio handles PET and PETG as standard, but the 12.5 KW barrel heating capacity makes the machine suitable for high-temperature engineering resins including PC, PCTG, PPSU, and BPA-free Tritan at melt temperatures up to 340 Celsius. Korean baby-care brands and pharmaceutical contract manufacturers have deployed the BPET-125V4 for 240 ml Tritan feeding bottles, 500 ml PC sports bottles, and sterile 100 ml PPSU medical containers with reject rates consistently under 0.3 percent in field-measured production data.<\/p>\n

Ever-Power ships the BPET-125V4 with platen dimensions compatible with standard 4-station high-tonnage ISBM tooling. For Korean operators moving up from a compact machine, existing smaller moulds will not drop in directly because the tie-bar spacing is different, but our in-house mould shop can build matched tooling for any bottle design you already run elsewhere, with a typical lead time of 45 to 55 working days. The machine footprint of 5000 \u00d7 2050 \u00d7 3000 mm fits comfortably within a standard factory bay with 3.5 m ceiling clearance, and installation takes a bilingual Ever-Power engineering team roughly one working week including commissioning and operator training.<\/p>\n

Technical Specifications & Cavity Matrix<\/h2>\n

Every parameter below comes directly from Ever-Power’s verified engineering data sheets and has been confirmed against production-test logs from installed BPET-125V4 units. Before finalizing a quotation, our engineering team reviews the screw-size choice, cavity count, and preform weight target against your specific resin grade. The cavity matrix further down represents practical maximum bottle dimensions; custom geometries outside these ranges are often feasible within the physical platen window.<\/p>\n

Heavy-Duty 4-Station Process Mechanics<\/h2>\n

\"heavy-duty<\/p>\n

The difference between a compact 4-station machine and the heavy-duty BPET-125V4<\/strong> is not in the number of stations or the general sequence \u2014 it is in the forces, temperatures, and residence times each station has to deliver when the mould is holding a 5-liter bulk bottle or a 12-cavity mid-size pharmaceutical array. The 11.6-ton chassis, the 685 KN clamping force, and the 640-liter hydraulic reservoir are all sized to make each of the four stations work without compromise at this scale.<\/p>\n

Station 1 \u2014 Injection with 685 KN Clamping<\/h3>\n

The 60 mm screw melts resin under controlled barrel heating before injecting 480 cubic centimeters of shot volume into the preform mould. The 685 KN injection clamping force is what allows the machine to hold 12 cavities closed against peak cavity pressures up to 80 MPa without flashing. This is the single spec that separates the BPET-125V4 from lighter-weight machines \u2014 without this clamping tonnage, a 12-cavity mould simply cannot run cleanly on PET at commercial cycle times.<\/p>\n

Station 2 \u2014 Heating, Tail Cutting & Pre-blowing<\/h3>\n

The 90-degree indexing step carries the hot preform into the conditioning zone. For heavy-wall bottles (2 mm and thicker, typical for 5-liter water gallons and thick-wall cosmetic jars), infrared heaters re-profile the wall temperature so the body stretches evenly without thinning at the base corners. A servo-driven cutter removes any sprue tail in the same station. The 12.5 KW heating power is sized specifically for the thermal mass of large preforms that would overwhelm a lighter machine.<\/p>\n

Station 3 \u2014 High-Pressure Stretch Blow<\/h3>\n

With the preform thermally profiled, the stretch rod drives axially at servo-controlled velocity while 2.0 to 3.5 MPa blow air inflates the plastic radially. The 286 KN blow clamping per side is sized for the larger projected mould area of wide-mouth bottles \u2014 a 148 mm neck food jar on a 2-cavity mould presents roughly 4.5 times the clamping area of a typical 28 mm cosmetic bottle, and without proper clamping tonnage the mould halves simply separate under blow pressure.<\/p>\n

Station 4 \u2014 Take-out & Quality Verification<\/h3>\n

Finished bottles are stripped from the core rod onto a servo-driven conveyor, upright and ready for filling or palletizing. Optional machine-vision inspection can be integrated here to tag any out-of-tolerance parts. For Korean food and pharmaceutical customers, this automated take-out eliminates the manual handling that traditional 2-step lines require, and consequently removes one of the largest sources of contamination risk in the entire production chain.<\/p>\n

<\/p>\n

Application Scenarios \u2014 What the BPET-125V4 Was Built For<\/h2>\n

\"large-format<\/p>\n

Five production scenarios have accounted for the majority of Korean and East Asian BPET-125V4<\/strong> deployments since 2023. Each benefits from a specific combination of the machine’s 685 KN clamping, 480 cm\u00b3 injection capacity, and 12-cavity tooling flexibility.<\/p>\n

5L PET Water Gallons & Bulk Beverage Containers<\/h3>\n

\"5<\/p>\n

Korean bulk water cooler manufacturers and craft-beverage bottlers have moved 5-liter single-cavity production to the BPET-125V4 because no compact ISBM machine can hold the 204 mm body diameter against blow pressure. At 1-cavity 5L format, the machine produces roughly 140 bottles per hour, which matches the throughput needs of regional Korean water-cooler bottlers who previously bought empty bottles from third-party suppliers. The 5 liter PET bottle blow molding machine<\/strong> category is dominated by Japanese and German imports worldwide, and the BPET-125V4 has become the economical Korean-accessible alternative.<\/p>\n

PC & Tritan Baby Feeding Bottles<\/h3>\n

\"PC<\/p>\n

Polycarbonate and Tritan both require processing at 300 to 330 Celsius, temperatures that smaller machines struggle to hold stable over 12-hour continuous shifts. The BPET-125V4’s 12.5 KW barrel heating combined with its thick-wall chassis (the mass acts as a thermal flywheel) keeps melt temperature within a 1.5 Celsius band, which is the benchmark for producing non-yellowing 240 ml BPA-free baby bottles. A 6-cavity configuration on 240 ml format hits roughly 2,100 bottles per hour with sub-0.3 percent rejects.<\/p>\n

Wide-Mouth Food Jars & Pickle Containers<\/h3>\n

\"wide<\/p>\n

The 148 mm neck diameter at 1-cavity configuration is what makes this machine especially attractive for the Korean kimchi, gochujang, honey, and peanut butter industries. Wide-mouth jars present a much larger projected area against blow pressure, and the 286 KN blow clamping holds the mould halves without separation. A 2-cavity 3-liter kimchi storage jar runs at about 240 bottles per hour, and the PET produced offers better shelf clarity than traditional recycled-glass jars at roughly half the weight.<\/p>\n

Pharmaceutical Bulk Containers & PPSU Medical Bottles<\/h3>\n

\"pharmaceutical<\/p>\n

For Korean pharmaceutical contract manufacturers producing 500 ml to 1-liter oral suspension bottles, IV fluid containers, and PPSU sterilizable flacons, the closed-loop 4-station design satisfies GMP cleanroom validation without requiring a separate isolator enclosure. A 4-cavity 500 ml PPSU configuration produces 1,800 bottles per hour, and the full enclosed melt-to-bottle path eliminates the contamination risk that plagues 2-stage lines where preforms travel between facilities.<\/p>\n

Household Chemical & Detergent Bottles<\/h3>\n

\"household<\/p>\n

Mid-volume Korean household chemical brands \u2014 dishwashing liquid, laundry detergent, bathroom cleaners \u2014 use 500 ml to 1-liter PET bottles in quantities that justify the BPET-125V4’s 8-cavity throughput. On a 500 ml mould running at 8 cavities, hourly output averages 3,200 bottles, which matches the daily demand of a mid-tier regional brand. The biaxial orientation from the stretch-blow process gives these bottles the drop-resistance needed for retail shelf handling, which recycled-content extrusion blow cannot match at the same wall thickness.<\/p>\n

<\/p>\n

Principales ventajas de un vistazo<\/h2>\n

The six strengths below are what Korean heavy-duty packaging buyers consistently highlight when comparing the EP-BPET-125V4 against imported alternatives and smaller Ever-Power platforms. Each has been measured on installed production lines.<\/p>\n

\"injection-stretch-blow-moulding-application-2\"<\/p>\n

\n
\n

685 KN Injection Clamping<\/h3>\n

More than twice the clamping force of a compact 4-station platform, which is what allows 12-cavity tooling and wide-mouth 148 mm neck geometries to run without flashing or mould separation.<\/p>\n<\/div>\n

\n

12-Cavity Flexibility<\/h3>\n

One chassis covers the full range from 1-cavity 5-liter bulk water gallons to 12-cavity 100 ml pharmaceutical vials. Floor-space efficiency per bottle produced is roughly 40 percent better than running two smaller machines.<\/p>\n<\/div>\n

\n

High-Temp Resin Capable<\/h3>\n

12.5 KW heating power with thermal flywheel mass holds PC, PCTG, PPSU, and Tritan melt within a 1.5 Celsius band over 12-hour shifts, enabling BPA-free baby and medical container production.<\/p>\n<\/div>\n

\n

Pristine Wide-Mouth Neck Finish<\/h3>\n

286 KN blow clamping per side and precision neck-ring cooling deliver dimensional thread tolerance within 0.05 mm on 148 mm food jar necks, which is the specification Korean kimchi and honey brands require for automated capping lines.<\/p>\n<\/div>\n

\n

Servo-Hybrid Energy Saving<\/h3>\n

Servo pumps idle toward zero during cooling phases, giving an average steady-state draw of 48 to 54 KW against the 77.5 KW nameplate peak. Total energy saving versus conventional fixed-pump heavy-duty machines reaches 30 percent.<\/p>\n<\/div>\n

\n

ASB & AOKI Mould Compatible<\/h3>\n

Standard platen bolt patterns match mid-to-large ISBM tooling from established Japanese suppliers, which lets operators preserve legacy mould inventory when upgrading their machine fleet.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

Material Compatibility \u2014 Deep Dive on PC, Tritan & PPSU<\/h2>\n

While the BPET-125V4 processes PET as its default workload, the single biggest reason Korean baby-care and medical buyers specify this platform is its high-temperature resin capability. The three engineering plastics below are where the 685 KN clamping and 12.5 KW heating capacity genuinely matter.<\/p>\n

Polycarbonate (PC)<\/h3>\n

PC processes at 280 to 310 Celsius with melt viscosity roughly three times that of PET at similar temperatures. The 60 mm screw with 24:1 L\/D ratio provides the residence time needed for complete plasticization, and the 685 KN clamping holds cavity pressure against PC’s higher injection back-pressure. Korean sports-bottle and reusable water-bottle brands choose PC for its shatter resistance and dishwasher durability. Mould temperature should sit at 85 to 95 Celsius for optimum surface finish, which the matched Ever-Power mould temperature controller delivers reliably.<\/p>\n

Tritan Copolyester (BPA-Free)<\/h3>\n

Tritan sits in a 260 to 290 Celsius processing window and is exceptionally sensitive to moisture and residence-time variation. Pre-drying at 110 Celsius for 4 hours to under 0.04 percent moisture is mandatory. The BPET-125V4’s enclosed hopper and optional gravimetric feeder prevent ambient moisture ingress, and the thick-wall machine chassis damps thermal drift during extended shifts. Typical applications include 240 ml baby feeding bottles, 500 ml reusable sports bottles, and clear pharmaceutical dosing containers.<\/p>\n

Polyphenylsulfone (PPSU)<\/h3>\n

PPSU is the premium choice for autoclave-sterilizable baby bottles and medical-device containers that must survive 140+ Celsius steam sterilization cycles. Processing temperatures run 310 to 360 Celsius, which requires specialty nickel-alloy barrel liners that we can fit at factory order. The machine holds the melt stable at this temperature range thanks to the proportional-integral-derivative (PID) controller on the 12.5 KW barrel heaters. PPSU is expensive per kilogram, so reject-rate performance matters more here than raw throughput \u2014 the BPET-125V4’s biaxial orientation consistency delivers sub-0.5 percent rejects on 500 ml PPSU medical bottles in field-measured production.<\/p>\n

When BPET-125V4 Is the Right Choice \u2014 Comparison Against Other Ever-Power Models<\/h2>\n

Selecting between the BPET-70V4, the HGY250-V4, and the BPET-125V4 comes down to three variables: the maximum bottle volume you need, the cavity count that matches your annual production plan, and whether you process high-temperature engineering resins. The table below summarizes the trade-offs. This comparison is provided strictly as selection guidance and does not imply any performance deficiency in the smaller or differently-positioned models.<\/p>\n

Buyers who land on the BPET-125V4 usually fall into one of three profiles: Korean baby-care brands moving PC or Tritan production in-house, food packaging plants producing wide-mouth kimchi or honey jars, or mid-tier beverage bottlers targeting 3-liter to 5-liter bulk containers. For applications requiring even heavier clamping for thick-wall cosmetic jars, the HGY250-V4<\/a> steps up to 16-ton rigidity. For entry-level operations, the compact HGY150-V4<\/a> covers up to 2500 ml single-cavity. The full range sits inside the M\u00e1quina ISBM de 4 estaciones<\/a> category.<\/p>\n
