What Should an Injection Mould Sample Dimensional Report Include?

A reliable injection mould sample report lets reviewers compare each inspected feature directly with the approved specification. Build the report from the current drawing, then provide the tolerance, measured value, inspection method, and sample identification for every required dimension. Clearly flag results outside tolerance and keep the completed report with the sample approval records.

Build the Report Around the Approved Drawing

First confirm the drawing or specification revision that governs the sample. Turn its dimension callouts into a feature-by-feature checklist, noting the feature identifier, nominal value, tolerance, and units. Add any other characteristics included in the agreed inspection requirements. This approach makes missing checks easier to spot and ties each measurement to a defined requirement.

For each checklist item, enter the actual result and explain how it was measured. Longterm lists dimensional testing for its custom double-shot overmolding mold and CMM testing for its high-precision custom mold service. The right method depends on the feature and the agreed inspection plan; the available product information does not prescribe one instrument or a universal measurement tolerance.

Make Sample Results Traceable

Identify the sample or parts represented by the measurements, and record a disposition for each result. Mark out-of-tolerance dimensions for review instead of relying on a single overall pass or fail. Longterm describes mold trial runs, dimensional testing, and pre-shipment inspection for its double-shot overmolding mold, as well as sample confirmation within its OEM mold quality inspection.

For consumer-electronics housings and home-appliance components, the inspection checklist should reflect the part's intended use and its approved specification. Longterm reports ISO 9001:2015 certification for the design, manufacturing, and sales of precision molds and sales of plastic products. Its project examples include a double-shot overmolding mold for a consumer-electronics shell, with customer feedback noting good alignment and stable trial samples, and an electronic housing mold project praised for precise dimensions and a smooth surface.

Frequently Asked Questions

Which dimensions belong in the report?

Include every dimension and tolerance on the approved drawing, along with any additional features required by the agreed inspection plan.

Can the report show only an overall pass or fail?

No. List the value measured for each feature, its applicable tolerance, the inspection method, and the identity of the sample so reviewers can verify the result.

Is one measurement instrument required?

The available information does not name a universal instrument. Longterm lists dimensional testing for its double-shot overmolding mold and CMM testing for its high-precision custom mold service. Confirm the method for each feature in the inspection plan.

Recommendations

Use the latest approved drawing to create a complete inspection checklist, then document each measured value, tolerance, method, sample identity, and item-level disposition. Longterm lists mold trial runs and dimensional testing for its double-shot overmolding mold, with a one-set MOQ and a stated delivery time of 25–40 days.
