01 / Engineering review
Product geometry, resin, machine, cycle, lid or label and automation are reviewed as one system. The sections below explain the project-specific decisions buyers should confirm before steel is released.
Engineering checkpoint 01
This 4CAV round container mould is engineered for food packaging programs that require visible tamper evidence and stable lid engagement after filling.
The anti-theft buckle geometry helps brands protect product safety during distribution while keeping high-speed molding efficiency.
Engineering checkpoint 02
Container wall thickness, buckle release force and lid matching tolerance all influence cycle stability, scrap risk and sealing consistency.
Hengqi can adjust cavity balance, cooling channels and steel selection according to your line speed target, resin and packaging specification.
Engineering checkpoint 03
Before confirming tooling, buyers should define how the anti-theft clasp will be inspected after filling, whether the pack needs IML decoration, and how much opening force is acceptable for consumers.
Those decisions affect clasp geometry, lid fit, ejection method and tolerance strategy, so they should be locked before steel cutting rather than corrected during sampling.
02 / Tooling specification
These values describe the current reference project. Final steel, cavity count, runner, machine and cycle target are confirmed from the customer product and production plan.

03 / Before shipment
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 processRecord the trial setup, resin, machine, process window, visible defects and required corrections.
Verify critical product and tooling dimensions against the approved drawing and agreed tolerances.
Check shot-to-shot consistency, thin-wall distribution and deformation risk across representative samples.
Review closure engagement, rim flatness, leak risk, opening force and stacking where the product requires it.
Confirm the practical cycle target under suitable resin, cooling, machine and automation conditions.
Provide agreed samples, trial video, inspection results and correction records for customer confirmation.
04 / Quotation checklist
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.
Product drawing or physical sample
Capacity, dimensions and target part weight
Resin grade and food-contact requirement
Target cavity number and annual output
Injection machine model and tonnage
Expected cycle time and automation plan
Matching lid, label or sealing requirement
Acceptance standard and delivery schedule
Send your drawing, sample photos and production target. Hengqi will review the project scope before preparing the quotation.

It forms a tamper-evident buckle structure that helps show whether the container has been opened after packaging.
Yes. The design supports in-mold labeling and can be configured for brand-specific container appearance requirements.
Provide container and lid drawings or samples, target output, resin grade, machine specifications and required tamper-evidence performance.
Yes. Hengqi can tune clasp geometry and tolerance targets around the required consumer opening feel, sealing performance and tamper-evidence standard.
Sampling should verify lid fit, buckle break performance, opening force, stack height, IML label clearance if used and whether the tamper-evident feature remains consistent across cavities.
