Injection molding quote request
Request an Injection Molding Quote for Custom Plastic Parts
Upload CAD files, 2D drawings, or sample photos for a custom plastic injection molding quote. Include material, quantity, finish, tolerance notes, destination, and project stage so the review can start with fewer follow-up questions.
Fast quote path
Send the essentials first
You do not need every detail finalized. The most useful starting information is the part file, material or part use, quantity, destination, and any critical surface, fit, tolerance, insert, or assembly requirement.
Files
STEP, STP, IGES, X_T, SLDPRT, DWG, DXF, PDF, ZIP, JPG, or PNG.
Part details
Material, color, finish, quantity, expected annual volume, and target timing if known.
Quality needs
Critical dimensions, visible surfaces, inserts, assembly fit, packing, and inspection requirements.
Backup contact
If upload fails, send files by email or WhatsApp and mention your destination country.

Injection molding RFQ form
Use this form for new molded parts, molds, insert molding, overmolding, assemblies, T1 sample follow-up, and low-volume production inquiries. If a file package is large or sensitive, email or WhatsApp is also available.
- Use CAD files when available, not screenshots only.
- Mark critical dimensions and mating part areas on the drawing.
- Tell us if the first order is for samples, pilot production, or repeat production.
- Include destination country so packing and shipment assumptions are clearer.
Your drawings are used only for quotation and manufacturability review. NDA can be signed before detailed technical discussion if required.
RFQ preparation
What to include for a more accurate plastic part quote
The quote can move faster when the manufacturing scope is clear. Use the table below as a practical checklist before uploading files.
| RFQ item | What to send | Why it helps |
|---|---|---|
| Part geometry | 3D CAD, 2D drawing, sample photos, or marked screenshots. | Allows review of wall thickness, draft, ribs, bosses, undercuts, inserts, gates, and parting lines. |
| Material | Target resin, similar material, use environment, flexibility, heat, strength, or cosmetic requirement. | Material affects shrinkage, tooling review, tolerance, finish, molding risk, and part cost. |
| Quantity and stage | T1 samples, pilot batch, low-volume production, first order, or estimated repeat demand. | The stage changes tooling assumptions, sample approval, inspection scope, and production planning. |
| Finish and color | Color target, texture, polish, visible surface, logo, painting, plating, printing, or packaging need. | Appearance requirements influence mold finish, gate location, defect review, and approval samples. |
| Critical dimensions | Marked CTQ dimensions, screw bosses, snap fits, sealing areas, insert positions, and mating parts. | Functional dimensions need different tolerance and inspection treatment than reference dimensions. |
| Destination and timing | Destination country, target schedule, packing notes, and any required shipment or inspection documents. | Helps avoid missing logistics, packing, and timeline assumptions in the quotation discussion. |
Choose the right quote route
Which injection molding quote path fits your project?
New plastic part
Send CAD files, application, material idea, first-order quantity, and any critical fit or appearance requirement.
Low-volume production
Share the pilot quantity, sample approval plan, repeat demand expectation, and inspection priorities.
Tooling or mold transfer
Explain the current mold status, part defects, desired corrections, and any previous sample feedback.
Insert molding or assembly
Send insert drawings, mating part details, assembly method, packaging needs, and functional requirements.

RFQ FAQ
Quote questions buyers ask before sending files
Can I request a quote before the drawing is final?
Yes. Send the current file, sketch, or sample photo with the application, target material, and quantity. The first review can identify missing details.
What if the upload fails?
Email the file package directly or send a WhatsApp message. Mention the project name and destination country so the inquiry can be matched.
Should I mark tolerance on the drawing?
Mark the dimensions that affect fit, assembly, sealing, inserts, moving parts, or product function. Avoid making every dimension tight by default.
What if the material is not selected?
Describe the part use, temperature, strength, flexibility, appearance, and chemical or outdoor exposure. Material can be discussed during review.
Large files or urgent project?
Send files directly by email or WhatsApp
Use direct contact if your file package is large, confidential, or difficult to upload through the form. Include CAD files, drawings, material, quantity, finish, destination, and project notes.
