Your Questions Before You Request a Quote
Review cost, timing, quality and mold ownership before you authorize tooling.
Know What Your Quote Covers
✓ Separate mold investment and part price
✓ Define your sample approval criteria
✓ Confirm lead time and shipping scope
✓ Agree mold ownership and change terms
01Design & quotation
What CAD files do you support?
Share your available 3D CAD and a dimensioned PDF drawing. STEP is a practical exchange format. Use the form to describe other formats and arrange transfer of native CAD files.
What information helps you quote accurately?
Send your 3D CAD and drawing revision, resin or application requirements, initial and annual quantities, critical dimensions, finish and target delivery date. Request separate mold and part pricing, with sampling, inspection, packaging and freight identified so you can compare equivalent scopes.
How does the DFM process work?
Your DFM review identifies geometry questions and proposed changes before tooling. Review the effect on fit, appearance and mold complexity, then approve the relevant drawing revision. Confirm whether mold-flow analysis or additional validation is included or quoted separately.
What materials and finishes can you support?
Discuss resin grade, color, texture, appearance and application requirements. Feasibility depends on the part and tooling design.
What affects injection molding cost?
Part size, resin grade, cavity count, tool complexity, order quantity, finish and inspection scope all affect cost. Ask for tooling charges and part pricing to be separated, with the quotation assumptions clearly stated.
When does my tooling lead time start?
Ask for milestones tied to your final drawing, material selection, commercial approval and sample sign-off. Distinguish tooling time, sample revisions, production and transit. Confirm the start conditions and delivery assumptions in your quote.
Can I arrange an NDA before sharing my design?
Discuss your NDA and file-transfer requirements before sending sensitive drawings. Identify the authorized contacts and the files needed for review; confirm the agreed transfer method with your project contact.
02Production & quality
Do you offer prototype, bridge and production tooling?
These are distinct approaches that can be evaluated around design maturity, volume and expected lifecycle. The quotation confirms the selected scope.
What quality documentation is available?
Tell us whether you need FAI, material documentation, CMM reports, PPAP or a certificate of conformity. Availability and scope are agreed during quotation.
Can you support prototype through repeat production?
Discuss a staged plan for your prototype, bridge and production needs. Confirm what must be approved before each stage and whether a new tool, material qualification or inspection plan is required as quantities grow.
How are injection molding tolerances agreed?
Identify the critical dimensions on your drawing. Resin shrinkage, part geometry, tooling and inspection method influence achievable tolerances. Confirm acceptance criteria during engineering review rather than assuming one tolerance applies to every feature.
Who owns the mold, and what happens if it needs changes?
Request written confirmation of mold ownership, storage, maintenance, expected service life, transfer conditions and change charges in your quotation. These project-specific terms should be agreed before tooling begins.
What if my first samples need changes?
Compare your samples with the agreed drawing and acceptance criteria. Record the issue, proposed correction and next approval step. Agree who authorizes changes, how costs are assigned and when revised samples will be available before proceeding.
What should my delivery quote include?
Confirm the shipping destination, packaging, freight scope, agreed delivery terms and responsibility for duties or taxes. Ask which inspection and material records accompany your shipment so receiving inspection has the information it needs.
