دستگاه ISBM تک مرحله‌ای ۴ ایستگاهه | خط تولید بطری PET — EP-HGY650-V4

A: A one-step ISBM machine (Injection Stretch Blow Molding) completes injection, stretch, and blow within a single machine cycle. Raw PET resin enters, finished bottles exit. A two-step RSBM (Reheat Stretch Blow Molding) line first produces preforms on a separate injection machine, stores them, then reheats and blows them on a second machine. The one-step process eliminates the reheating energy cost (saving roughly 30% in kWh/1,000 bottles), removes the contamination risk during preform storage and transfer, and requires ~40% less floor space. The tradeoff is throughput: a standalone RSBM blower can exceed 24,000 bottles/hr, while the EP-HGY650-V4 targets up to 1,200 bottles/hr — which is the right range for small-to-medium batch production where product cleanliness and run flexibility outweigh raw speed.

A: With a trained two-person crew, mould changeover on the EP-HGY650-V4 takes 90–120 minutes, including purging the injection unit and verifying process parameters on the HMI. All production recipes (temperatures, pressures, timings) are saved as named files, so re-loading a previously run mould takes under 5 minutes. The machine supports container volumes from 50 ml to 5,000 ml — meaning a contract packager can run a 100 ml cosmetics bottle in the morning and a 2 L water bottle in the afternoon. This is one of the most common reasons B2B buyers choose a compact one-step ISBM machine over a dedicated high-volume line.

A: The machine requires: (1) Power supply — 380 V / 50 Hz / 3-phase (460 V / 60 Hz export version available), 45 kW installed load, dedicated 80 A breaker recommended. (2) Compressed air — minimum 0.8 MPa at 3.5 m³/min for low-pressure circuits; a separate high-pressure compressor providing 3.5 MPa at 1.2 m³/min is required for blow. (3) Cooling water — ≥40 L/min at ≤20 °C; a closed-loop chiller is strongly recommended in ambient temperatures above 28 °C. (4) Floor loading capacity — minimum 12 kN/m², as the machine weighs approximately 7,800 kg. Our engineering team provides a full utility layout drawing within 5 business days of order confirmation.

A: Yes. The EP-HGY650-V4 is validated with PET blends containing up to 30% post-consumer rPET without hardware modifications, provided the rPET has been properly dried (moisture content <50 ppm) and has an IV (Intrinsic Viscosity) of 0.72–0.84 dL/g. For blends above 30% rPET, we recommend an optional in-line crystallising dryer upgrade. As sustainability regulations under the EU Packaging and Packaging Waste Regulation (PPWR) and US state-level EPR programmes require higher recycled content, the machine’s compatibility with rPET gives buyers a clear compliance pathway without replacing equipment.

A: Based on data shared by customers across beverage, personal care, and pharmaceutical packaging — running 2 shifts, 5 days/week at an average bottle price saving of $0.018 per unit vs. outsourcing — the EP-HGY650-V4 typically reaches payback in 18–24 months. After-sales support includes: 12-month parts warranty on all mechanical and electrical components; free remote diagnostics via Siemens TeleService for the first 2 years; on-site commissioning and 3-day operator training by a factory engineer; a spare-parts kit (wear items for 2,000 production hours) shipped with the machine; and a dedicated after-sales account manager available 5 days/week across GMT, EST, and CST time zones. Spare parts for the EP-HGY650-V4 are stocked in our overseas warehouses for dispatch within 48 hours.
