PDCPD MOQ & Lead Time Guide: What to Expect at a Chinese RIM Manufacturer
A practical breakdown of how batch size affects per-part cost, tooling choices, and realistic timelines — based on real production data from our Jiangsu facility.
Quick Reference: Batch Size vs. Cost
| Batch Size | Mold Type | Per-Part Cost (USD) | Tooling (USD) | Total Lead Time |
|---|---|---|---|---|
| 1–10 pcs (prototype) | CNC from solid | $80–200 | $0 | 7–14 days |
| 50–200 pcs | Aluminum 7075 | $35–60 | $3K–8K | 25–35 days |
| 200–1,000 pcs | Aluminum 6061-T6 | $20–40 | $5K–12K | 30–40 days |
| 1,000–5,000 pcs | Steel P20 | $12–25 | $12K–25K | 35–50 days |
| 5,000+ pcs | H13 Hardened | $8–18 | $20K–40K | 45–60 days |
Indicative pricing for a typical 300×200×50mm part with 3mm wall. Actual quotes depend on geometry, surface finish, and post-processing.
Phase 1: Prototype (1–10 pcs, 7–14 days)
Before committing to tooling, we recommend a CNC prototype:
- Material: Machined from PDCPD sheet or substitute (ABS/PU board for form-fit testing)
- Cost: $80–200 per part depending on complexity
- Lead time: 7–14 days including finishing
- Purpose: Form-fit-check, mounting hole verification, aesthetic review
This step catches 90% of design issues before you spend a dime on tooling.
Phase 2: Low-Volume (50–1,000 pcs, 25–40 days)
The sweet spot for most startups and product launches:
- Aluminum mold (7075 or 6061-T6): Fast to machine, lower cost, good for 100–2,000 shots
- First article: 18–25 days from PO to first molded part
- Batch delivery: 25–40 days total to FOB Shanghai/Ningbo
- Cost advantage: 60–80% cheaper tooling than injection molding
Phase 3: Production (1,000–5,000+ pcs, 35–60 days)
- Steel mold (P20 or H13): Longer life, tighter tolerances, hardened cavities
- First article: 25–35 days
- Batch delivery: 35–60 days depending on complexity
- Economics: Per-part cost drops 40–60% vs. low-volume phase
Hidden Costs to Watch For
- Surface finish: Class-A paint adds $3–8/part. Gel coat adds $2–5/part.
- Inserts and threaded bushings: $1–3/insert installed.
- Quality documentation: CMM reports, material certs — typically $200–500/batch.
- Shipping: Ocean freight from Shanghai ~$800–2000 per pallet to EU/US.
- NDA and IP protection: Free with standard template; custom NDAs reviewed in 2 days.
How to Shorten Lead Time
- Provide STEP files from day one: Saves 3–5 days of file conversion
- Approve DFM within 48h: Each day of delay pushes your mold start
- Choose aluminum for first batch: Even if you'll switch to steel later
- Pre-approve paint colors: RAL/Pantone codes in advance
- Use our stock mold bases: For simple shapes, we have interchangeable bases
Real Example: 300-Piece UAV Fuselage
| Item | Detail | Cost | Time |
|---|---|---|---|
| DFM Review | 2 rounds of feedback | Free | 3 days |
| Aluminum Mold | 7075, 2-cavity | $6,500 | 20 days |
| First Article | 5 pcs, inspected | $250 | 2 days |
| Production Run | 300 pcs + paint | $9,000 ($30/pc) | 10 days |
| Paint & QC | PU topcoat, CMM | $1,500 | 5 days |
| Total | FOB Shanghai | $17,250 | ~30 days |
