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 2CAV anti-theft square box mould is designed for food containers that need tamper-evident opening behavior during retail, takeaway and delivery handling.
The anti-theft buckle structure helps prevent box reuse and gives end users a clear opening signal, which supports hygiene control and brand trust.
Engineering checkpoint 02
For tamper-evident packaging, buckle geometry, opening force, wall thickness and lid fit tolerance must be reviewed together to avoid false locks or weak seals.
Hengqi can evaluate sample drawings, resin type, output target and automation method to confirm cavity layout, hot runner design, steel selection and cycle expectations.
Engineering checkpoint 03
Anti-theft square box projects should define the first-open signal, buckle break behavior, lid matching tolerance and stacking requirement before mold construction begins.
If the package will use IML, the label area, robot clearance, static control and take-out path should be reviewed with the mould design because these details affect production stability as much as the container shape.
A stronger technical brief helps buyers compare suppliers beyond headline price, especially on buckle durability, sample validation speed, spare-part planning and long-run service support.

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.

Capacity, dimensions and target part weight
Resin grade and food-contact requirement
Target cavity number and annual output
Injection machine model and tonnage

It creates tamper-evident opening behavior, helping distributors and end users identify whether the container has been opened or reused.
Yes. The mould supports in-mold labeling and Hengqi can align label position with your box artwork and structural design.
Please share box and lid drawings or samples, resin type, cavity target, machine tonnage, cycle expectation and monthly output plan.
Sampling should check buckle break force, lid sealing fit, stacking stability, IML label position if used, drop behavior and whether the first-open signal is clear to the end user.
