How to Get an Injection Molding Quote from a 3D File: 5-Step Process (2026)
The 5-Step Quote Process
Getting an injection molding quote from your 3D file takes five steps:
- Prepare your files — 3D CAD (STEP/IGS) + optional 2D drawing with critical tolerances
- Send your RFQ — files + material + annual volume + requirements
- Receive quote — within 24 hours
- Review and optimize — feedback → confirm design and material
- Start production — mold T1 samples in 30–55 days, mass production in 10–15 days after approval
Key facts: DFM analysis is free for every project, quotes arrive within 24 hours, typical MOQ starts from 1,000+ pieces (depending on part size and complexity), and we operate 33 injection molding machines (80T–2700T) under one roof.
The 5-Step Quote Process, Step by Step
Step 1: Prepare Your Files
A complete RFQ gets you a faster, more accurate quote. Here’s what to send:
- 3D CAD file — STEP (.stp) or IGS is preferred; PRT also accepted.
- 2D drawing (optional but recommended) — a PDF/DWG with critical tolerances and material notes.
- Key information — material preference (or ask for recommendations), annual volume (not one-time quantity), target unit price, surface finish, and delivery timeline.
- No CAD file? No problem — we can quote from physical samples and reverse-engineer the design.
Step 2: Send Your RFQ
Submit through our Instant Quote page or email the engineering team directly. Include everything from Step 1 in your first message.
Step 3: Receive Quote (Within 24 Hours)
Our engineers review your design for manufacturability — draft angles, wall thickness, gate locations, sink marks, and moldability — and return:
- A free DFM (Design for Manufacturing) analysis
- An itemized quote (mold + material + processing + secondary operations)
- A proposed timeline
Step 4: Review and Optimize
Review the DFM feedback. Common improvements we suggest: adjusting draft angles, adding fillets, or adjusting material selection. Confirm the design and quote — this is the point to lock your design to avoid later changes.
Step 5: Start Production
Once confirmed, we build the mold (T1 samples in 30–55 days; complex molds 45–60 days), deliver samples for your approval, then run mass production in 10–15 days after approval, with weekly progress reports throughout.
What Affects Your Quote & How to Get the Most Accurate One
Several factors drive your quote — knowing them helps you get a precise price faster:
| Factor | Impact |
|---|---|
| Material | We process PP, ABS, PE, HDPE, PC, PA (Nylon), POM, PVC, PMMA. Engineering plastics cost more per kg than commodity resins. |
| Annual volume / MOQ | Typical MOQ starts from 1,000 pieces, depending on part size and complexity. Larger volumes lower per-part cost (mold amortization). |
| Tolerances | Standard tolerances cost less; we hold tolerances down to ±0.05 mm. |
| Surface finish | SPI/VDI finishes affect tooling cost and lead time (texturing adds days). |
| Complexity | Undercuts, side actions, and high cavity counts increase mold cost and lead time. |
Tips for the most accurate quote:
- Provide the complete 3D file plus a 2D drawing with critical tolerances.
- Give your real annual volume — not a one-time quantity — so cavity count and unit price are right.
- Specify material and surface finish upfront.
- State all requirements in one message to avoid back-and-forth rounds.
- Ask what the quote includes — mold, samples, modifications, and shipping terms.

FAQ
Q: What files do I need to get an injection molding quote?
A: A 3D CAD file (STEP/IGS preferred, PRT accepted) plus an optional 2D drawing with critical tolerances. No CAD? Photos or physical samples work too.
Q: How long does it take to get a quote?
A: You receive a free DFM analysis and an itemized quote within 24 hours of sending your RFQ.
Q: What is the minimum order quantity?
A: Typical MOQ starts from 1,000+ pieces, depending on part size and complexity.
Q: How long from quote to production?
A: Mold T1 samples take 30–55 days (45–60 for complex molds), then mass production takes 10–15 days after sample approval.
Q: Can you quote from photos if I don’t have CAD files?
A: Yes. We can quote from high-quality photos or physical samples and reverse-engineer the design.
