Neck lightweighting

Aoki machines can blow neck as well as body sections. This enables neck lightweighting within a range that will not affect closure fit.
No special molding is required. General purpose closures can also be used.

Can general purpose closures be used?

Yes, they can be used.

ネックの軽量化をした場合、どのくらい軽くなりますか?

To what extent can necks be lightweighted?

Though it depends on neck shape, as a yardstick, narrow necks up to about Φ20mm can be lightened by 0.5–1g, medium-sized up to about Φ40mm by 2–3g, and wide mouth up to about Φ80mm by 4–6g or more.

What is neck lightweighting?

Neck lightweighting involves reducing the thickness of neck section walls within a range that will not affect closure fit. This both saves molding material and shortens the molding cycle. No special molding is required.
