Two-Step
ISBM Machine

In one-step ISBM, the preform is injected and transferred — still hot — through conditioning, stretch blowing and ejection in a single continuous cycle. It never cools to room temperature. In two-step RSBM, the preform is injected, cooled fully, stored in bulk, then reheated in an IR oven before being stretch-blown. One-step retains heat energy and supports PETG, Tritan and complex geometries via its conditioning station. Two-step is limited to standard PET and round shapes, but enables much higher output speeds at scale.
Both produce stretch-blown bottles

Technically possible, commercially impractical. PETG and Tritan are amorphous resins that cannot be reheated uniformly from ambient temperature. The IR oven creates a surface-to-core temperature differential of 50–80°C — far greater than the ±5–10°C achievable in a one-step conditioning station. The result is wall thickness variation of 25–40% versus 8–12% on a 4-station one-step machine. For cosmetic or pharmaceutical bottles, two-step PETG is not viable.
One-Step only for PETG / Tritan

One-step preforms exit the conditioning station at ±5–10°C temperature uniformity. Two-step preforms exit the IR oven at ±8–15°C — the surface heats faster than the core. This less uniform temperature requires higher pressure to ensure complete cavity filling: 3.5–4.0 MPa versus 2.0–3.2 MPa on one-step. This is why 40-bar oil-free compressors are mandatory for RSBM lines.
Two-Step: 3.5–4.0 MPa main blow pressure

For standard round PET bottles at current Russian electricity rates (6.5–8.5 RUB/kWh), the total cost of ownership breakeven is approximately 25–35 million units per year per SKU. Below this, one-step has lower combined capital and operating cost. Above 50M/yr, two-step rotary RSBM delivers a decisive unit cost advantage. Between 20M and 50M we build a detailed model for your specific scenario at no cost.
We calculate the breakeven for your scenario

Yes — but only on the one-step platform. ASB molds are designed for the 4-station one-step workflow. The HGY150-V4-EV is 100% ASB-12M mold compatible — your existing tooling installs directly without modification. Two-step RSBM uses a completely different mold interface and cannot accept ASB molds in any configuration.
One-Step: ASB-12M compatible

Yes — the HGY150-V4-EV processes both PET and PETG on the same machine. Switching resins requires a barrel purge (30–45 minutes) and parameter adjustment. No mechanical modification needed. The same machine can run commodity PET water bottles in one shift and premium PETG cosmetic jars in the next. Two-step RSBM configured for PET cannot produce viable PETG bottles.
One-Step: PET and PETG on same machine

One-step HGY series: full mold change in under 2 hours with a trained 2-person crew. No preform inventory clearance required. Two-step RSBM: blow mold change alone takes 1.5–3 hours. If the preform specification changes, add preform stock clearance and IR oven profile reprogramming — total 4–8 hours minimum. For operations running more than 3–4 different SKUs per month, this changeover penalty makes two-step uncompetitive regardless of volume.
One-Step: under 2 h Two-Step: 4–8 h minimum

We provide Russian-language technical consultation, remote diagnostics via video call, and spare parts from local Moscow stock for critical wear components (neck rings, blow pins, seals, IR lamps). For commissioning, engineers travel to site for initial setup and operator training (3–5 days on-site). Every machine quotation includes a recommended 12-month spare parts kit for uninterrupted operation without external supply dependency.
