Functional-datum quality control
Inspection follows the component relationships that make an IML or thin-wall mould fit, move, seal and repeat—not only isolated dimensions on a report.
Visual engineering record
Each section links a real Hengqi image with the engineering purpose it supports. Buyers can understand what is reviewed, what is manufactured and what evidence is checked before delivery.
01 / Inspection planning
The inspection route is built around the product, mould structure and approved functional datums.
Critical positions, profiles, flatness, perpendicularity, distances and mating relationships are selected according to their role in the mould.
02 / Working components
Cores, cavities, inserts, sliders, wear plates, locating blocks and shut-off features do not carry equal risk.
Inspection attention is concentrated where positional error or profile deviation could affect assembly, movement, sealing, wall thickness or product release.
03 / Machining feedback
Results are compared with the approved CAD model and tolerance plan, then returned to the responsible manufacturing stage.
This makes inspection an engineering feedback channel, allowing correction before the component becomes buried inside final assembly.
04 / Assembly gate
Verified datums and mating interfaces give the assembly team clearer evidence about fit and alignment.
Assembly findings are recorded against design intent so corrective work remains traceable instead of becoming undocumented bench adjustment.
05 / Production validation
Trial samples reveal whether the controlled geometry supports filling, wall distribution, sealing, stacking, label placement and ejection.
Product measurements and cavity comparisons are reviewed with the mould and process condition before final release.
Real inspection evidence
These images were recorded in Hengqi's inspection room. They show how an actual mould component is fixtured, probed and compared with the released CAD data before an engineering decision is made.
01 / Component setup
A four-cavity mould component is positioned on the granite table with the probe working directly around the formed surfaces and reference features.
The setup is planned around the features that influence assembly, wall distribution, alignment and repeatable product geometry—not around a generic inspection demonstration.
02 / Inspection team
Inspectors work beside the measuring equipment so the physical feature and its digital nominal can be reviewed together.
Unexpected deviation is assessed by function and returned to engineering, machining or fitting before the component is released.
03 / Inspection capacity
The inspection room provides space for mould plates and components while technicians prepare programs and review results beside the machines.
The exact measurement scope and buyer-facing report are agreed for each project so the evidence matches the approved acceptance plan.
Measurement workflow
The inspection loop protects the relationships that influence mould assembly and repeatable production.
Identify the functional datum, feature risk and approved tolerance requirement.
Probe or verify the selected geometry with the appropriate inspection method.
Review actual results against CAD, tolerance and assembly context.
Return findings to machining, fitting or engineering before release.
Start with the production requirement
Inspection scope, reports and acceptance points should be agreed before final machining and trial.
Send project informationBuyer questions
The inspection plan focuses on project-specific functional parts such as cores, cavities, inserts, sliders, locating features, shut-offs, wear interfaces and assembly-critical datums.
Checking critical component relationships before fitting helps prevent positional, shut-off and alignment problems from being discovered only after the mould is assembled.
Required reports and documentation should be agreed during project review. Hengqi can define the measurement scope and delivery records around the approved acceptance plan.
