One-Step Injection Stretch Blow Molding Machine (4-Station) Y250-V4-B

Comprehensive Overview of the Upgraded ISBM Machine

The One-step injection stretch blow molding machine (four-station) Y250-V4-B is the ultimate evolution in high-tonnage plastic container manufacturing. Engineered as a highly advanced, industrial-grade blow molding machine, it perfectly synchronizes raw material melting, preform injection, thermal conditioning, and stretch blowing into a single, highly efficient cycle.

The “B” designation signifies a profound structural upgrade over its predecessor. Designed to accommodate exceptionally large or specialized Japanese-style molds, this One-Step Blow Molding Machine features extended mold strokes, a taller frame, and massive clamping forces. It is the premier choice for manufacturing visually stunning, thick-walled PET, PETG, and Tritan containers for luxury cosmetics, medical devices, and premium beverages.

The Y250-V4-B maximizes container precision by utilizing a highly synchronized, servo-driven 4-station rotary indexing system:

• Station 1: High-Pressure Injection: Using an energy-saving nano-infrared heating system, resin is rapidly plasticized and injected into the preform mold under extreme clamping force, guaranteeing precise weight and clarity.
• Station 2: Temperature Conditioning: (The 4-Station Advantage) The warm preform is transferred to a dedicated conditioning station where core and barrel temperatures are equalized, ensuring flawless material distribution for complex shapes.
• Station 3: Biaxial Stretch Blow Molding: High-pressure air and precise servo-driven stretch rods orient the preform. The massive blowing clamping force ensures absolutely zero-flash production.
• Station 4: Automated Ejection: The fully cooled container is gently extracted and automatically dropped onto a conveyor, entirely eliminating human contact and preventing surface scratches.

The extended strokes of the Y250-V4-B make it the perfect platform for highly complex, multi-cavity custom precision ISBM molds. Our engineering expertise ensures your tooling matches the machine’s immense power perfectly:

• Valve-Gate Hot Runner Systems: Delivers precise, drool-free injection across high-cavitation molds (e.g., up to 14 cavities), ensuring a crystal-clear bottle bottom without stringing.
• Conformal Cooling Channels: Deep, 3D-mapped cooling pathways rapidly dissipate heat from thick-walled preforms, significantly reducing overall cycle times and boosting daily yield.
• Premium Swedish Steel Alloys: Molds are crafted from hardened S136 or Stavax stainless steel to withstand millions of cycles under high clamping forces without any microscopic deformation

Q1: What distinguishes the Y250-V4-B from the standard V4 model?

A: The “B” model features significant structural upgrades, including extended mold strokes and a taller frame architecture, enabling compatibility with larger, more specialized molds (such as AOKI types) and deeper container designs.

Q2: What materials are compatible with this equipment?

A: The machine is optimized for high-clarity engineering plastics, including PET, PETG, Polycarbonate (PC), Tritan, and specialized high-clarity PP.

Q3: How does the 4-station process improve bottle quality?

A: The dedicated 2nd station provides targeted temperature conditioning. It perfectly equalizes the preform’s internal and external heat before stretching, eliminating thin spots in non-round or extremely thick-walled containers.

Q4: What is the maximum number of cavities supported by the Y250-V4-B?

A: Due to its heavy-duty clamping system, it can comfortably support high-output molds with up to 14 cavities for smaller format bottles (e.g., 20ml dropper bottles).

Q5: How do the servo systems save energy during production?

A: The multiple servo-driven hydraulic pump systems provide massive power exactly when needed (during clamping/injection) and drop to near-zero RPM during idle or cooling phases, slashing overall electricity consumption.

Q6: Is the machine capable of producing thick-walled cosmetic jars?

A: Absolutely. The machine’s high injection pressure packs dense preforms perfectly, and the one-step process prevents any surface scratches, resulting in thick-walled jars that mimic the premium feel of glass.

Q7: Do you provide customized hot runner molds?

A: Yes, we provide complete turnkey solutions. Our engineering department designs and manufactures premium S136 stainless steel, valve-gated hot runner molds tailored to your specific container designs.

Q8: What is the maximum bottle volume the machine can blow?

A: When operating in a single-cavity mold configuration, the Y250-V4-B is capable of blowing large-format containers up to 2500ml.

Q9: Are the internal hydraulic and pneumatic components reliable?

A: We exclusively integrate top-tier global components, including Japanese servos, Taiwanese YUKEN hydraulic control valves, and American Parker high-pressure pneumatics, ensuring decades of 24/7 reliability.

Q10: What kind of after-sales training and installation is provided?

A: We offer rigorous Factory Acceptance Testing (FAT) before shipment, followed by comprehensive onsite installation, mechanical commissioning, and deep operational training for your factory personnel.
