Injection moulding forms components
Injection moulding forms parts by injecting material into a mould. Extrusion blow moulding inflates a hollow parison, while injection stretch blow moulding starts with an injection-moulded preform. These process names describe different routes, not interchangeable labels for the same appearance.
| Route | Starting form | Brief focus |
|---|---|---|
| Injection | Mould cavity | Components |
| EBM | Parison | Hollow container |
| ISBM | Preform | Preform and bottle |
Evaluate the route with the design
Provide shape, neck, material and functional requirements when discussing the manufacturing route. Ask the supplier to explain the proposed approach and its constraints. A brand brief need not prescribe every equipment detail, but it should make the required outcome clear.
Do not use a process name as acceptance
Whichever route is proposed, approve drawings, component identities, appearance and functional checks. A manufacturing label does not establish formula, transport or sealing performance. Base acceptance on the evidence and records agreed for the specific project.
Your Project Checklist
- Share the complete structural brief
- Confirm the proposed forming route
- Accept against the product specification
Frequently Asked Question
Must the bottle and closure use the same process?
No. Select the process for each part’s geometry, material and function.
