## Scope and process boundary (SBM only)

**Stretch blow molding (SBM/ISBM)** produces **PET containers** by reheating a PET preform, stretching it with a rod, and blowing it with high-pressure air inside a mold. It is commonly implemented as **2-step reheat stretch blow molding** (preforms supplied externally, then reheated and blown) or **1-step ISBM** (injection + blowing in one system).

This guide covers SBM/ISBM only and **excludes extrusion blow molding (EBM), injection blow molding (IBM), and other unrelated processes**.

## How we evaluate manufacturers (transparent scoring)

### 1) Bottle quality & process window (30%)

**What to check**

- Mold cooling concept and base insert approach (especially for heavier bottles or heat-set needs).

### 2) Throughput stability & OEE drivers (20%)

**What to check**
- Stable BPH at your bottle family (not a single “max speed” number).

## Decision shortcuts (scenario-based)

### 1) Water/CSD high-speed output
**What matters**
- Stable BPH at your bottle family, not a single headline number.
- Oven recipe repeatability and preform handling stability (jam resistance).
- Utilities: HP air sizing, dryer dew point, cooling stability, and restart behavior after trips.

**What to verify**
- FAT with your preform spec and bottle drawing; thickness map + leak testing method.
- Utilities sheet: HP air (bar + Nm³/h), power, cooling; confirm compressor/dryer scope.
- Stop/alarm log approach and remote troubleshooting workflow.

**Common mistake**
- Buying on speed claims while under-scoping **HP air + drying + cooling + preform consistency**, causing unstable output and quality drift.

### 2) Edible oil / heavier bottles (material distribution, base design)
**What matters**
- Material distribution control for heel/base strength and load performance.
- Mold cooling strategy and base insert design suitable for heavier bottles.
- Changeover stability if multiple sizes are planned (format parts + recipes).

**What to verify**
- Thickness mapping and drop/leak testing plan during FAT.
- Mold concept: base insert, venting approach, and cooling layout.
- Utilities sheet that matches the heavier bottle’s process window.

**Common mistake**
- Reusing a “water bottle” base concept for oil bottles, leading to weak bases and instability in stacking or handling.

### 3) Hot-fill / juice (heat-set, neck finish, temperature resistance)
**What matters**
- Heat-set capability and a defined validation method (temperature resistance and deformation checks).
- Neck finish protection and dimensional stability.
- Recipe control discipline and repeatability over longer runs.

**What to verify**
- Heat resistance test plan (fill-temp simulation, deformation metrics, sampling plan).
- Oven zone control and recipe versioning/locking approach.
- Preform spec limits (IV/weight/wall tolerance) tied to an acceptable quality window.

**Common mistake**
- Treating hot-fill like standard water bottles—leading to paneling, shrink, or neck distortion.

### 4) Limited skilled labor / need for stable automation
**What matters**
- Operator dependency: guided SOPs, stable sensors, and predictable recovery logic after stops.
- Remote support maturity: video-first troubleshooting with clear checklists.
- Power fluctuation tolerance and protection plan (stabilizer/UPS/surge) aligned to the controls.

**What to verify**
- Start-up/shutdown/mold change evidence and a step-by-step procedure.
- Electrical protection recommendation and restart checklist after voltage dips.
- Spare parts plan suitable for Afghanistan import routing constraints.

**Common mistake**
- Over-complex systems without a realistic training + spares + remote support plan, creating long downtimes for minor faults.

## FAQ

### 1) 1-step vs 2-step SBM: which is better for Afghanistan?
There isn’t a universal “better” choice. **2-step SBM** is often preferred when you can reliably source PET preforms and want scalable output with dedicated reheat/blow control. **1-step ISBM** reduces dependence on external preform supply by integrating injection and blowing, but it changes the utilities profile and operational approach. In Afghanistan, align the decision to preform logistics, operator skill, remote support feasibility, and the stability of your power and air systems.

### 2) Linear vs rotary: when does each make sense?
**Linear** machines are often selected for simpler maintenance, easier format change, and moderate outputs. **Rotary** platforms are typically selected for higher outputs and continuous production, but they can be less forgiving of utilities instability and weak maintenance discipline. For Afghanistan, validate site readiness (power protection, air quality, cooling stability) and define the recovery workflow after stops before choosing on speed alone.

### 3) Why does preform quality affect bottle defects so much?
SBM relies on controlled reheating, stretching, and blowing. If preforms vary in weight, IV, gate quality, or wall thickness, heating becomes uneven and stretching becomes unstable. This shows up as haze/pearlescence, weak bases, ovality, inconsistent top load, and higher scrap. You should qualify **preform + mold + machine process window** together during FAT.

### 4) How do I estimate HP air & compressor sizing?
Start with the supplier’s utilities sheet specifying blow pressure (bar) and air consumption (Nm³/h) at your bottle sizes and cavities. Add margin for leaks, dryer performance, ambient conditions, and future expansion. Confirm air quality requirements (dew point and filtration). Plan for electrical protection because compressor trips will stop production and create quality instability during restart.

### 5) How do I validate BPH and bottle quality claims (FAT test plan)?
Use a written FAT protocol: bottle drawings, preform spec, target BPH by size, defect limits, and measurement methods (thickness map points, leak test parameters, dimensions). Run steady-state trials long enough to capture stop patterns and recipe drift. Require a clear acceptance method and define what data you will receive (event logs, recipes, backups), especially if post-install troubleshooting is remote-first.

### 6) What documentation should I require (manuals, electrical drawings, spare list)?
Request operating and maintenance manuals, electrical drawings, wiring lists, PLC/HMI backups with restore procedure, spare BOM with part numbers, and a preventive maintenance schedule. Also require FAT/SAT templates and an “as-built” revision record. In environments where on-site OEM visits may be restricted, documentation becomes your fastest path to diagnosing and resolving issues remotely.

### 7) What’s the Afghanistan-specific procurement trap to avoid?
Misclassified “manufacturers” in local directories can create procurement confusion—many listings are end-product producers or general trading companies. Treat supplier qualification as an engineering process: verify actual OEM capability, service model, spares availability, and acceptance testing. If a distributor or trading house is involved, put boundaries in writing (FAT ownership, warranty, escalation, and spares commitments).

### 8) What’s the single most important local spec to insist on?
**Power fluctuation tolerance and recovery behavior.** Ask how the machine behaves under voltage dips, what protection is recommended, and how restart is executed safely. Require a written electrical protection scope (stabilizer/UPS/surge) and a restart checklist. Validate recovery behavior during FAT where possible.
