Daily-use Product Moulds
The lunch box project centers on multi-compartment filling, flatness, snap position, sealing edge — helping you understand the main structural risks and mould approach before submitting drawings.

Lunch Box mould, focused on multi-compartment filling and flatness.
For lunch box mould, review multi-compartment filling and flatness alongside snap position and sealing edge. Mark these features on the current drawing and state the material, appearance and assembly requirements so that the tooling discussion uses agreed part references.
For the lunch box project we recommend front-loading risk into the DFM stage, building the mould solution around multi-compartment filling, flatness, snap position, sealing edge.
The project starts by assessing multi-compartment filling, confirming structural, cosmetic and assembly risks to reduce later mould rework.
In the mould-solution stage we focus on flatness, arranging core, cavity, inserts, ejection and cooling for stable moulding.
During trial-mould we watch snap position on the sample part, tuning venting, ejection or local structure to the actual part condition.
Before mass production we keep reviewing sealing edge, keeping the daily-use product moulds project consistent in dimensions, appearance and assembly feedback.
Send the following to start an assessment: 3D/2D drawings, sample photos, material requirements, expected quantity and lead time — we assess from structure, material, mould risk and trial-mould plan.
