MOLDING

Insert molding

Insert molding places a prepared component into the tool before molding around it.

ENGINEERING DOSSIER

Coordinate insert identity, placement, resin flow and verification after molding

Insert identity and preparation

Define insert material, revision, surface condition, orientation and any area that must remain exposed.

Placement and retention

Show locating features and explain how the insert must resist movement during molding and use.

Resin flow around the insert

Review wall transitions, knit or witness zones and functional clearances around the embedded component.

Verification after molding

Confirm insert presence, orientation, exposed features, fit and any assembly-critical relationship.

MANUFACTURING ROUTE

Route logic for Insert molding

Define insert material, revision, surface condition, orientation and any area that must remain exposed. Review wall transitions, knit or witness zones and functional clearances around the embedded component.

Show locating features and explain how the insert must resist movement during molding and use. Best input: Part and insert CAD together.

DECISION CONTROLS

Release controls specific to Insert molding

Best input

Part and insert CAD together

Key risk

Placement, movement and exposed zones

Release evidence

Insert identity and interface inspection

PROJECT-SPECIFIC DECISION DATA

Decision record before Insert molding release

Use this table to connect the process decision to the CAD, drawing and inspection evidence. Values remain project-specific until reviewed.

Decision item	What must be resolved	Evidence at release
Insert identity and preparation	Define insert material, revision, surface condition, orientation and any area that must remain exposed.	Part and insert CAD together
Placement and retention	Show locating features and explain how the insert must resist movement during molding and use.	Placement, movement and exposed zones
Resin flow around the insert	Review wall transitions, knit or witness zones and functional clearances around the embedded component.	Insert identity and interface inspection
Verification after molding	Confirm insert presence, orientation, exposed features, fit and any assembly-critical relationship.	Insert identity and interface inspection

DECISION QUESTIONS

Insert molding route and release questions

What must be defined before reviewing Insert molding?

Define insert material, revision, surface condition, orientation and any area that must remain exposed. Show locating features and explain how the insert must resist movement during molding and use.

Which interfaces need project-specific confirmation?

Review wall transitions, knit or witness zones and functional clearances around the embedded component. Escalate Placement, movement and exposed zones and any geometry, access, material or interface requirement that the drawing does not resolve.

What should accompany release?

Confirm insert presence, orientation, exposed features, fit and any assembly-critical relationship. Insert identity and interface inspection

PROJECT BRIEF

Insert molding project brief and release checklist

Use these page-specific checks to turn the Insert molding route into reviewable CAD, drawing and inspection inputs.

Geometry and route input — Insert identity and preparation

Define insert material, revision, surface condition, orientation and any area that must remain exposed. Include the relevant CAD orientation, interfaces and quantity in the review brief.

Release evidence — Placement and retention

Show locating features and explain how the insert must resist movement during molding and use. Name the drawing dimensions and inspection evidence required at release.

RFQ handoff — Resin flow around the insert

Review wall transitions, knit or witness zones and functional clearances around the embedded component. Upload controlled CAD/drawing inputs and state the unresolved route decision.
