IBM vs IBBM vs ISBM: Choose a Plastic Bottle Molding Route
LIANXIN's IBM, IBBM and BPET ISBM equipment serve different bottle and process requirements. Start with the package rather than choosing a machine family from its name.
Process comparison
| Route | Published LIANXIN scope | Typical decision signals | Validation boundary |
|---|---|---|---|
| IBM-H / IBM-E | Injection blow molding; hybrid-servo or all-electric families | Controlled neck finish, repeatable dimensions, verified PE/PP/PS/EVA-family project materials | Bottle, resin, mould and output require project confirmation |
| IBBM-50E | Fully electric horizontal four-station injection blow molding | PET/PETG high-value packaging, transparency, surface and cosmetic-packaging requirements | Exact material, appearance and compliance documents require project confirmation |
| BPET-70V4 / 125V4 | One-step four-station injection blow and injection stretch blow functions | PET/PETG and other catalogue-listed transparent materials; stretch/blow requirement; cavity-volume matrix | Package performance and regulated use require customer validation |
Decision sequence
1. Define contents, material and end-market validation.
2. Freeze bottle drawing, weight, dimensions and neck finish.
3. Identify whether stretch orientation or a one-step preform-to-bottle route is required.
4. Define appearance, wall distribution, closure and leak criteria.
5. Define cavities, target output and utilities.
6. Compare the matching LIANXIN family and model.
Review all products, matched moulds, auxiliary equipment or submit the bottle requirements.
