Plastic MoldingSpecify the part, material and inspection together

Injection-molded components for electronic products, instruments and industrial equipment need a clear relationship between part design, resin grade, finish and acceptance method. We review the application and drawing before confirming a production scope.

From design to parts

Build a production brief around real requirements

The approved part drawing and sample establish what is being made. Tooling, process and inspection are then matched to that definition.

Part DFM

Review draft, wall thickness, gate and ejection effects, surface requirements and assembly features. Any recommended 3D changes return to the customer for approval.

Material definition

Specify resin manufacturer and exact grade when required, including color, filler and regrind policy. “Virgin resin” and traceable manufacturer source are different requirements and should be stated separately.

Acceptance and delivery

Agree the critical dimensions, measurement method, visual criteria, sample approval, inspection records and packaging needed for the actual part order.

Material review

Evaluate grades against the application

PA6, PA66, glass-filled PA, PBT, POM, PEEK and PPE+PS can be starting points for a material discussion. Select the exact grade against the part requirements, then check processing and equipment suitability before confirming the production route.

For an enclosure or instrument component, tell us about heat, electrical, chemical, wear, dimensional and appearance requirements. Include the grade, manufacturer and any flame-performance documentation you need reviewed.

Provide the part drawing and target weight so achievable dimensions and weight can be checked against the geometry, material, tool and available equipment.

Evidence and reports

Keep compliance claims tied to a specific part

Reports and declarations must identify their material or part, revision and applicable scope.

RoHS

For electrical or electronic applications, identify the material or part and the restricted-substance evidence needed. EU RoHS guidance

FCC

FCC Part 15 relates to radio-frequency devices and the final equipment. Include enclosure or assembly requirements in the device brief. FCC Part 15

Medical and flame performance

For medical device parts, state the intended use and contact conditions. Check flame requirements against the exact grade and test record. FDA biocompatibility guidance

Questions buyers ask

Frequently asked questions

Can you quote from only a product photo?

A photo may start the conversation, but a meaningful production scope needs a drawing or 3D model, target material, expected volume and the features that must fit or be measured.

Do you use virgin resin or allow regrind?

State your manufacturer, grade, traceability, virgin-resin and regrind requirements in the RFQ. They are separate project conditions that should be confirmed in the quotation.

What part size or weight can be molded?

Send the drawing or 3D model, target weight and resin grade. Feasibility depends on the geometry, mold design and available equipment, so the range is confirmed for the specific part.

Can one report cover every material and part?

No. Any declaration or test report must be checked for its named material or part, revision, test conditions and intended application.

Next step

Define the part, tool and delivery scope together.

Share the application, drawing revision, material requirements, expected quantity and acceptance needs. Sensitive files can be exchanged after an NDA through a channel we agree together.
