What Should an Injection Mould Sample Dimensional Report Include?

A useful injection mould sample report lets reviewers verify each required dimension against the approved specification. Build it from the current drawing, then record the requirement, measured value, inspection method, and sample identification for every checked feature. Highlight any result outside tolerance and state whether the sample is accepted or needs review.

Build the Report Around the Approved Drawing

First confirm the drawing revision and specification that govern the sample. Convert every dimension with a stated tolerance into a checklist item, and add any other features included in the agreed inspection plan. For each item, note its feature identifier, nominal value, tolerance, and units so the measurement can be traced back to its requirement.

Record the actual result and the method used to obtain it. The method should suit the feature and follow the agreed inspection plan. Longterm lists dimensional testing for its custom double-shot overmolding mold and CMM testing, surface inspection, and multi-cycle mold trials for its high-precision custom mold service. The available product information does not prescribe one instrument or a universal measurement tolerance.

Make Results Traceable and Easy to Review

Identify the sample or parts represented by the report, and connect each recorded measurement to that identification. Mark out-of-tolerance results individually rather than relying on a single overall pass or fail. Include a clear disposition, such as accepted, rejected, or pending review, so dimensional issues are not hidden by the summary status.

For consumer-electronics housings and home-appliance components, the report should cover the dimensions relevant to the part’s intended use and approved specification. Longterm describes mold trial runs, dimensional testing, and pre-shipment inspection for its double-shot overmolding mold. Its OEM mold quality inspection also includes sample confirmation.

What to Include for Each Dimension

Quality Context

Longterm reports ISO 9001:2015 certification for the design, manufacture, and sale of precision molds and the sale of plastic products. Its project examples include a double-shot overmolding mold for a consumer-electronics shell, for which the customer noted 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 a sample report?

Include every dimension and tolerance specified on the approved drawing, along with any extra features named in the agreed inspection requirements.

Can the report show only an overall pass or fail?

No. For each reported feature, include the measured value, its applicable tolerance, the inspection method, and the sample identity. This makes the decision verifiable.

Is there a standard instrument that must be used?

The available information does not define one instrument for every feature. Longterm lists dimensional testing for its double-shot product and CMM testing for its high-precision custom mold service. Confirm the appropriate method in the inspection plan.

Recommendations

Use the approved drawing as the report checklist, then document the actual value, tolerance, measurement method, sample identification, and disposition for each inspected dimension. Longterm lists mold trial runs and dimensional testing for its double-shot overmolding mold; the stated minimum order quantity is one set, with a delivery time of 25–40 days.
