Improvements in productivity and efficiency
Nissei ASB Machine Co., Ltd., leading manufacture of machines and moulds for injection stretch blow moulding of PET and other plastics, demonstrated live moulding of four separate technologies at the K 2025.
Global debuts
Four machines, each from a different Series in the ASB line-up and each showcasing improvements in productivity and efficiency using various technologies, had made live moulding demonstrations, with three of the four making their global debuts at the K 2025 exhibition.
1. PF36/36-600 (high output) – 1.5-Step Injection Stretch Blow Moulding + 13 gram, 500ml water bottle at 18,000bph in 100% rPET.
2. PM-90/111N (global debut) – Vertical Clamp Compact Preform Injection Moulding + 10 gram PET preform at 20,000pph in 100% rPET
3. ASB-70DPH/50E (global debut) – 1-Step Hybrid-Electric Injection Stretch Blow Moulding with low energy consumption + 500ml HDPE oval “trigger” style bottle for household cleansers.
4. HSB12-4N/111N (global debut) – 1.5-Step, Injection Stretch Double Blow Heat-Set Moulding + 2-liter Returnable & Refillable PET Bottles for carbonated soft drinks (CSD) – 7.5% lighter than industry standard with exceptional performance.
- PF36/36-600 + 500ml water bottle
Redefining PET Bottle Production with the Power of 1.5-Step Moulding.
The PF36 Series is a line of PET injection stretch blow moulding machines that merge 1-Step and 2-Step processes into a “1.5-Step” system. The displayed model has 36 injection cavities and 12 blow cavities, producing 500ml bottles at 18,000 units per hour. Its 3:1 blow-to injection ratio ensures high efficiency, shorter cycles, and lower operating costs.
Compared to equivalent 2-Step systems, it requires only one-third of the floor space, consumes up to 20% less energy by using residual heat from injection, and delivers higher, more consistent product quality without dependence on external preforms.
The machine uses hybrid actuation systems of hydraulics, pneumatics, and servo motors, all managed by ASB’s Vision1™ control system, which supports OPC UA standards for advanced connectivity, integration, remote monitoring, and diagnostics.
Pure performance: precision-moulded 500ml generic water bottle
The 500ml, 13gram water bottle is a typical design used in global markets. In line with circular economy trends the PF36/36-600 will demonstrate moulding using 100% recycled PET (RPET) material without compromising output or product quality.
- PM-90/111N + preform moulding
Global debut: Setting the standard in compact preform moulding
The PM-90/111N, ideal for small to medium-scale preform production, offers 12, 18, 24, or 36 cavities depending on preform size. Its vertical mould clamping and injection system, derived from the proven PF36 Series, delivers precise high-speed performance while minimizing the machine’s footprint. Preforms pass through an integrated cooling system for 3.5 cycles, ensuring stable, fully cooled output resulting in top-quality bottles.
Internal studies show around 40% lower investment cost, 30% less floor space, and up to 20% lower energy use per preform compared to similar machines. Control and monitoring are managed via ASB’s Vision1 system as standard.
High-quality preforms moulded to perfection
The 10gram preform is suited to generic 500ml water bottles with the neck design conforming to the current European standard for tethered cap retention after opening. Moulding resin is 100% rPET.
- ASB-70DPH/50E + 500ml HDPE trigger spray
The next generation Hybrid Electric for smarter, cleaner bottle production.
The ASB-70DPH/50E is a fully re-engineered version of ASB’s best-selling model, now featuring electric operation of all major movements, including the advanced injection unit and preform stretching, with hydraulics used only where high clamping force is needed. This hybrid design minimizes energy use, hardware cost, and maintenance while enhancing control and productivity. Energy consumption for driving power is reduced by an estimated 25% compared to the hydraulic version, while faster, more precise servo movements shorten cycle times, boost output, and ensure smoother, quieter operation. Servo-driven stretch rods improve moulding consistency, especially with sensitive resins or complex designs. The machine comes standard with ASB’s Vision1 control and monitoring system and remains fully compatible with existing mould sets.
Enhanced HDPE designs moulded by ISBM
HDPE resin offers strong resistance to household products containing chlorine or bleach, while the flawless neck finish, and no weld lines that ensures leak-free performance from the ISBM process has driven steady growth in ASB’s HDPE projects. While ISBM has traditionally produced simple round HDPE containers, ASB’s advanced preform conditioning station now enables non round and specialty shapes. The high precision front-face parting line of the blow mould further boosts productivity, increasing mouldable cavities of the demonstrated container from 5 to 7—a 40% rise over conventional designs.
- HSB12-4N/111N + 2L returnable & refillable CSD bottle
ASB Unveils World’s First 1.5-Step double blow heat-set machine – Advancing sustainable bottle production.
ASB introduces the world’s first 1.5-Step machine capable of moulding double blow heat-set returnable and refillable PET bottles directly from resin. Combining the strengths of 1-Step and 2-Step moulding, it delivers high-quality output in a compact footprint. ASB’s Double Blow Heat Set technology increases material crystallinity and reduces stress, enhancing thermal stability and resistance to environmental stress cracking—ensuring high reusability even at lighter weights. With sustainability in focus, ASB leverages its packaging expertise and advanced moulding systems to meet the growing demand for eco-friendly solutions.
Engineered for sustainability: CSD bottles built for 25+ return and refill cycles
The bottle meets stringent global standards with a 4.2 gas volume rating, making it suitable for all leading carbonated soft drink brands and capable of more than 25 return and refill cycles. Weighing just 90 grams—7.5% lighter than the industry standard—and made with up to 30% rPET, it offers superior sustainability. Returnable and refillable PET bottles are about 90% lighter and have a 30% lower carbon footprint than glass. Though twice as heavy as single-use PET bottles, their extended lifespan of around 25 refills means that only 8-10% of PET material is consumed for an equivalent volume of filled product.
