Blow Moulding
Blow moulding for hollow parts.
Blow moulding for HDPE fuel tanks and other hollow components, with construction, interfaces and validation requirements defined for the application.
What we can support
A controlled route for hollow functional components.
Material, wall-thickness distribution, tooling and test requirements are reviewed for the part.
Hollow parts
Blow moulding
HDPE fuel-tank and hollow-component enquiries begin with the drawing, material and construction. Multilayer or barrier requirements need a separate feasibility review.
Read the hollow-component guide
Control
Wall distribution and interfaces
Review wall distribution, mould split, necks, mounting points and mating interfaces together before tooling release.
Review toolingEvidence
Process validation
Agree dimensional, leakage and other applicable functional checks for the actual part, including test conditions and acceptance limits.
Review validationHow the work moves
Hollow components move through a controlled blow-moulding route.

Checks before blow moulding.
| Stage | Review focus | Expected output |
|---|---|---|
| Application | Hollow-part function, envelope, material grade, specified construction and service conditions | Defined component brief |
| Part and tool | Wall distribution, mould split and interfaces | Defined moulding route |
| Process | Material preparation and controlled blow-moulding cycle | Trial parts checked against the agreed requirements |
| Validation | Agreed dimensional, leakage and other application-specific methods, conditioning and acceptance limits | Inspection and approval records |
