Mould

The packaging box project centers on case flatness, cover snap-fit, thin-wall filling, edge flash — helping you understand the main structural risks and mould approach before submitting drawings.

mould overview

Packaging Box mould, focused on case flatness and cover snap-fit.

For packaging box mould, review case flatness and cover snap-fit alongside thin-wall filling and edge flash. Mark these features on the current drawing and state the material, appearance and assembly requirements so that the tooling discussion uses agreed part references.

Mould focus

For the packaging box project we recommend front-loading risk into the DFM stage, building the mould solution around case flatness, cover snap-fit, thin-wall filling, edge flash.

01
case flatness

The project starts by assessing case flatness, confirming structural, cosmetic and assembly risks to reduce later mould rework.

02
cover snap-fit

In the mould-solution stage we focus on cover snap-fit, arranging core, cavity, inserts, ejection and cooling for stable moulding.

03
thin-wall filling

During trial-mould we watch thin-wall filling on the sample part, tuning venting, ejection or local structure to the actual part condition.

04
edge flash

Before mass production we keep reviewing edge flash, keeping the custom plastic moulds project consistent in dimensions, appearance and assembly feedback.
