Tooling & Molding Questions Project Scope, Interfaces & Inspection

Define the critical feature, datum, tolerance limits and measurement method on the drawing. Mold components, metal inserts and finished plastic parts have different requirements; one general tolerance cannot substitute for their project-specific acceptance criteria.

Share the press and platen drawings during the RFQ. Interface requirements can then be reviewed and recorded in the approved mold design. Final compatibility depends on the supplied machine information and approved specifications.

Ask for the required steel certificates, heat-treatment records, and dimensional inspection report in the RFQ. Availability and report scope should be confirmed and listed in the project quotation.

Timing depends on part complexity, materials, mold design, sampling requirements, and approval cycles. Request a project schedule with the quotation and agree milestone dates before work starts.

Contact the company to arrange a separate written NDA. Do not submit confidential designs until both parties have agreed to and signed the applicable document.

Describe the application, drawing revision, material grade, expected quantity, key features, inspection needs and delivery destination. For overmolding, identify both materials and the interface function; for insert molding, include the metal insert drawing and supply plan. Agree an NDA before exchanging confidential files.

An initial feasibility discussion supports quotation. After price and order confirmation, the formal DFM stage reviews draft angles, wall thickness and demolding, followed by any agreed moldflow analysis and mold design. Proposed part changes and design deliverables require customer confirmation.

State the manufacturer, exact grade, source documentation and traceability requirements. Virgin resin and restrictions on regrind are separate conditions; record the agreed material policy in the quotation rather than relying on a resin-family name.

No. Restricted-substance reports must match the named material or part and scope. FCC equipment requirements concern the electronic device, not a generic resin certificate. Medical-device material assessment depends on intended use and contact conditions; relevant records and tests must be identified for the project.

A public image can be saved or captured. Only authorized, redacted previews should be published. Sensitive CAD, detailed dimensions and complete mold design files are exchanged after an NDA through an agreed channel.
