Blow moulding · by quote

Hollow parts, blown to shape

For bottles, jerrycans, ducts, tanks and anything else that needs to be hollow and sealed. Send your part file or a sample and the target volume, we'll quote the mould, the parison setup and the parts together.

Aluminium or steel moulds, single to multi-cavity, 4–6 weeks

Wall control

Parison programming for even wall in deep-draw areas

Secondary work

Trim, leak test, labelling, assembly, leak-proof capping

Choosing a material

The material decides stiffness, chemical resistance, clarity and how the part is filled or used. Barrier layers and regrind content also shape the quote, so tell us what the container will hold.

HDPE: Stiff, chemical-resistant and economical. The default for bottles, jerrycans and tanks.
PP: Handles higher temperatures and live hinges. Useful for hot-fill containers and closures.
PET: Clear, strong and pressure-tolerant. Stretch-blown bottles for drinks and cosmetics.
Barrier coex: Layered structure that slows gas and solvent permeation. Useful for fuels, chemicals and long shelf life.

What the tooling review covers

Hollow geometry and parting

Blow moulding handles undercuts and complex hollow shapes well, but the parting line, pinch-offs and trim need planning with the mould.

Wall distribution

Deep draws and sharp corners thin out the wall. Parison programming and sensible radii keep strength where it matters without wasting material.

Volume and decoration

Annual volume decides mould cavities and machine size. Tell us about labelling, colour and leak testing so the quote covers the whole job.
