contact usHengqi Precision Mould builds custom thin wall food container moulds for packaging manufacturers that need stable output, fast cycles, and consistent sealing. The product range covers PP lunch box moulds, round food container moulds, square box moulds, anti-theft packaging moulds, soup container moulds, sauce cup moulds, and compartment tray moulds.
Thin-wall food container production depends on more than cavity number. The mould must fill quickly, cool evenly, release cleanly, and keep sealing surfaces stable across long runs. Hengqi reviews the product wall thickness, material flow, container geometry, buckle structure, lid fit, stacking requirement, and injection machine condition before confirming the final tooling plan.
For lunch boxes and compartment trays, partition wall strength and demolding are important. For soup bowls and round containers, roundness, lid fit, and heat deformation need close control. For anti-theft containers, buckle detail and repeatability become key parts of the mold design.
| Product range | PP lunch boxes, round containers, square boxes, soup containers, sauce cups, crisper boxes, and compartment trays |
|---|---|
| Cavity options | 2 / 4 / 6 / 8 / 16 cavities, configured by product size, output target, and machine tonnage |
| Wall thickness focus | Thin-wall packaging production, commonly around 0.35-0.45 mm depending on product design |
| Mould steel | P20, 4Cr13, imported or domestic 2344, or customer-specified mold steel |
| Runner system | Needle valve hot runner or needle point hot runner for balanced filling and efficient cycles |
| Key design points | Cooling layout, sealing rim, anti-theft buckle, stackability, demolding angle, and dimensional stability |
Thin-wall food container moulds are designed to reduce material usage while keeping stable product strength.
Cooling, runner balance, and ejection layout are reviewed around short cycle time and long production runs.
Container shape, capacity, compartment layout, anti-theft buckle, and lid sealing details can be customized.
Hengqi supports mold design, machining, assembly, mold trial, sample checking, and production maintenance guidance.
Please send the product drawing or sample, capacity, material, target wall thickness, cavity number, machine tonnage, lid requirement, and whether the container needs an anti-theft buckle or compartment layout.
Yes. Hengqi can design container moulds and matching lid moulds as a set, helping control sealing fit, stacking, demolding, and production consistency.
Typical products include PP lunch boxes, round food containers, square food boxes, sauce cups, soup bowls, crisper containers, compartment trays, and tamper-evident packaging.
Cycle time is strongly affected by cooling design, wall thickness, runner balance, resin flow, ejection stability, and machine condition. Hengqi reviews these factors during mold design and trial.
Send your container drawing, sample photo, capacity, target wall thickness, material, machine tonnage, and lid requirement. Hengqi can review the mold structure and prepare a practical tooling proposal for production.
