Inside a 60-day reference build.
This is a reference schedule for a four-cavity thin-wall round container mould. Each phase connects a real manufacturing step with the engineering result required before the project moves forward. Final timing is confirmed from the approved product, steel route, hot runner, machine and acceptance plan.

Days 01–0501 / Design release & mould base
Control starts with the product, lid and mould-base datums.
The container drawing, lid engagement, target weight, wall distribution, stack height and take-out method are reviewed as one production system. After release, Hengqi prepares the mould-base reference faces and hole layout in house so later machining starts from a controlled foundation.
- Container and matching-lid geometry approved together
- Cooling, ejection and robot clearances reviewed before steel release
- Mould-base plates prepared around the released design
Days 06–2802 / Five-axis geometry
Complex core geometry is machined with fewer datum transfers.
HISION five-axis machining supports groove milling, angled features and multi-surface contour work. Reducing repeated re-clamping helps protect the relationship between the thin-wall core, rim geometry and assembly interfaces before precision finishing.
- Coordinated access to grooves and contoured surfaces
- Fewer re-clamping steps between related features
- Predictable finishing allowance for the next operation
Days 29–4203 / Precision finishing
Critical interfaces receive a controlled finishing route.
Makino, Mazak and OKK machining resources finish cores, cavities, inserts and assembly interfaces. On selected critical features, and where geometry and measurement conditions permit, machining control can be maintained within 3 μm to support fitting accuracy and repeatable cavity relationships.
- Core, cavity and insert interfaces finished to the approved route
- Stable allowances prepared for fitting and polishing
- Selected critical features linked to dimensional inspection
Days 43–4804 / Component verification
Finished cores are checked before assembly closes the system.
Critical dimensions and component relationships are reviewed before the mould is assembled. Measurement feedback is connected to the released drawing so any correction is completed while the individual insert or core remains accessible.
- Critical dimensions compared with the approved drawing
- Fitting relationships reviewed before final assembly
- Inspection findings returned to the responsible machining stage
Days 49–5805 / Assembly & valve gates
Four cavities become one balanced production system.
The cooling circuit, moving interfaces, ejector layout and valve-gate positions are assembled and checked together. Hengqi's MAX platform can be specified for direct engineering control, while YUDO or HUSKY systems can be integrated when required by the customer's plant standard.
- Valve-gate position and four-cavity balance checked as one system
- Cooling and ejection functions reviewed before trial
- MAX, YUDO or HUSKY selected around the approved specification
Days 59–6006 / Trial & sample delivery
The mould is validated against the real production target.
Trial work reviews filling balance, part weight, wall distribution, roundness, lid fit, stacking and the practical cycle under suitable resin, machine, cooling and automation conditions. Representative samples and the agreed evidence package are then prepared for customer confirmation.
- Cavity-to-cavity balance and part weight recorded
- Lid fit, roundness and stacking checked on representative samples
- Cycle target evaluated under the agreed production conditions
Hengqi proof system
The product page should also prove who can deliver the mould.
Buyers do not evaluate the product concept alone. They also need evidence that the supplier can design, machine, measure, trial and support the mould through production acceptance.

03 / Before shipment
Acceptance evidence should answer production questions.
The exact checklist is agreed for each project. These are the core records buyers normally use to confirm dimensions, function, output and correction closure before shipment.
View inspection process01
T0 / T1 trial records
Record the trial setup, resin, machine, process window, visible defects and required corrections.
02
Dimensional inspection
Verify critical product and tooling dimensions against the approved drawing and agreed tolerances.
03
Part weight and wall thickness
Check shot-to-shot consistency, thin-wall distribution and deformation risk across representative samples.
04
Lid fit or sealing test
Review closure engagement, rim flatness, leak risk, opening force and stacking where the product requires it.
05
Cycle and continuous running
Confirm the practical cycle target under suitable resin, cooling, machine and automation conditions.
06
Final evidence package
Provide agreed samples, trial video, inspection results and correction records for customer confirmation.
04 / Quotation checklist
Send enough production data for a useful tooling proposal.
A drawing or sample is the starting point. Machine, resin, output, closure and acceptance details allow Hengqi to review cavity layout, steel, runner, cooling and automation with fewer assumptions.

Questions to resolve before quotation.
Can the 1000ml round container mould be customized for my lid?
Yes. The rim shape, sealing fit and stack height can be adjusted from the container and lid drawings or physical samples.
What information is needed for a 1000ml food container mould quote?
Please provide the container drawing or sample, resin, weight target, wall thickness, cavity quantity, machine tonnage and expected cycle time.
Is the 6 second cycle time fixed for every 1000ml round box?
No. The cycle target depends on material, wall thickness, cooling design, machine performance and automation layout.
Can this mould support IML or branded packaging requirements?
The container geometry can reserve label or logo areas, and Hengqi can review the automation clearance needed when the production line requires in-mold labeling.
What should be checked during the 1000ml round container mold trial?
Check lid fit, container roundness, stack height, wall consistency, ejection marks, cavity weight balance and whether the actual cycle time is stable after continuous running.
