Key Highlights

Nissei ASB's 1.5-step double-blow heat-set machine can produce stress-resistant PET bottles directly from resin, suitable for carbonated beverages with over 25 reuse cycles.
The hybrid electric ASB-70DHP/50E offers fully electric movements for all major functions, improving precision and reducing hydraulic dependency, ideal for trigger-style household bottles.
The vertical PM-90/111N preform machine can produce up to 20,000 bottles per hour using recycled PET, with lower investment and energy costs, and supports multiple cavity configurations for flexibility.
All new machines incorporate Nissei ASB’s Vision1 control system, ensuring advanced monitoring, compatibility with existing molds, and optimized molding processes.
These innovations cater to small- and medium-sized companies seeking sustainable, cost-effective solutions for high-quality PET bottle manufacturing.

Nissei ASB took the wraps off three new machines at K 2025: a 1.5-step injection stretch double-blow heat-set molding machine, a one-step hybrid electric injection stretch blow molder and a compact vertical preform injection molding machine.

Nissei ASB describes the HSB12-4N/111N as the world’s first 1.5-step, double-blow heat-set machine. It is capable of molding double-blow heat-set PET bottles directly from resin.

The company said the new machine combines one-step and two-step molding in a compact footprint. The double-blow heat-set technology increases material crystallinity and reduces stress, which makes the bottles more resistance to stress cracking.

The unit produces round, square or oval bottles that are suitable for all carbonated beverages and capable of more than 25 return-and-fill cycles. The bottle demonstrarted at the K Show weighed 90 grams and was made with 30 percent recycled PET.

Using a full mold set in the double-blow mechanism will allow molding containers that are capable of being filled at up to 203 degrees Fahrenheit. These machines provide a good fit for small- to medium-scale filling companies, according to Nissei ASB.

The ASB-70DHP/50E blow molding machine is targeted at trigger-style bottles.

Based on one of Nissei’s best-selling models, the new one-step machine, the ASB-70DHP/50E, is targeted at trigger-style bottles used primarily for household cleaning products. It’s been fully redesigned, so all major movements are now electric, including the advanced injection unit and preform stretching. Hydraulics are used only for high clamping force.

Servo-driven stretch rods improve molding consistency, especially with sensitive resins or complex designs, according to the company.

The new machine comes standard with ASB’s trademarked Vision1 control and monitoring system and is compatible with existing molds.

Nissei ASB’s advanced preform conditioning station enables molding of specialty shapes. HDPE resin used for trigger containers has typically been used only for round containers.

The PM-90/111N + Preform Molding vertical clamp machine is economical and compact.

The PM-90/111N + Preform Molding vertical clamp machine can produce up to 20,000 bottles per hour in 100 percent recycled PET.

It can accommodate 12, 18, 24 or 36 cavities, depending on the preform size. It is aimed at small- to medium-sized preform production. A 10-gram preform is suited for generic water bottles.

The vertical mold clamp and injection systems are derived from ASB’s PF36 machine series.

Preforms pass through an integrated cooling system for 3.5 cycles.

Nissei ASB said the PM-90 series requires about 40 percent lower investment, uses 30 percent less floor space and up to 20 percent less energy per preform compared with similar machines.

It comes standard with ASB’s Vision1 control system.
