If you are sourcing custom plastic components from China, the short answer is this: a simple machined plastic part typically costs between USD 2 and USD 30 per piece in small-to-medium batches, and express shipping on batch orders usually adds another USD 1 to USD 5 per part depending on weight, quantity, and destination. Prototypes cost more per piece because setup and programming are spread across very few parts, while larger batches push the unit price down quickly. Below, we break down exactly where the money goes, what shipping really adds, and how to calculate a realistic landed cost per part before you request a quote.
Every figure in this guide is an indicative industry range, not a fixed price. Your actual quote will depend on your drawing, material, tolerance, and order quantity — which is why a complete RFQ matters so much.
A quote for china plastic cnc machining is built from eight cost components. Understanding them helps you see why two seemingly similar parts can be priced very differently:
Machine time and setup usually dominate the part price itself. That is why the single biggest lever you control is quantity: amortize setup over 200 parts instead of 5, and the unit price drops dramatically.
Plastic is not one material — it is a family with wildly different price points and machining behavior. Choosing the right resin for the job (not the most exotic one) is one of the easiest ways to control cost:
| Material | Material Cost | Machinability | Typical Uses |
|---|---|---|---|
| ABS | Low | Excellent | Prototypes, housings, enclosures |
| POM (Delrin / Acetal) | Low–Medium | Excellent | Gears, bushings, precision parts |
| Nylon (PA6 / PA66) | Low–Medium | Good | Wear parts, structural components |
| PC (Polycarbonate) | Medium | Good | Transparent guards, lenses, covers |
| PMMA (Acrylic) | Low–Medium | Good | Optical and display parts |
| PTFE (Teflon) | High | Moderate — soft, needs sharp tooling | Chemical seals, low-friction parts |
| PEEK | Very high — often 10x+ commodity resins | Moderate | Medical, aerospace, high-temperature parts |
The practical takeaway: if your part works in POM or ABS, do not spec PEEK. Material cost differences of this scale flow straight into your per-part price, especially at higher volumes.
Quantity is where Chinese plastic cnc machining services become genuinely cost-effective. These ranges assume a simple-to-moderate part (think a bracket, bushing, or small housing) in a common engineering plastic:
| Quantity | Indicative Unit Price (Part Only) | Why |
|---|---|---|
| 1–5 pcs (prototype) | USD 30–150+ | Setup and programming dominate; machine time is a small share |
| 50–100 pcs (small batch) | USD 5–30 | Setup amortized; cycle time becomes the main driver |
| 500+ pcs (production) | USD 1–10 | Optimized programs, reused fixtures, bulk material purchasing |
Complex geometry, tight tolerances, or exotic material can push any of these ranges higher. The reliable way to map your real cost curve is to ask for two or three quantity tiers in a single RFQ — good factories quote this by default.
Here is where plastic parts have a hidden advantage: they are light. Most engineering plastics weigh a fraction of an equivalent metal part, so freight cost per part stays modest. Your three main shipping options:
Two more line items to budget for: import duties and taxes, which depend on your destination country and the HS code declared for your parts, and Incoterms. With EXW or FOB you arrange and pay freight yourself; with DDP the supplier delivers with duties paid and you see one all-in number. If you want a true "cost per part including shipping" figure, ask for a DDP quote or itemized freight — that is the only honest way to compare suppliers.
Let's put real (illustrative) numbers together. Say you order 200 pieces of a POM housing, 80 g each — about 16 kg gross with packaging:
| Cost Component | Basis | Amount (USD) |
|---|---|---|
| Machined parts | 200 pcs × USD 8.00 (material, setup, machine time, finishing, inspection) | 1,600 |
| Export packing | Cartons, protective wrap, palletizing | 40 |
| Express freight | 16 kg × ~USD 7.50/kg | 120 |
| Duty and import fees | Indicative; varies by destination and HS code | 60 |
| Total landed cost | — | 1,820 |
| Landed cost per part | 1,820 ÷ 200 | ~USD 9.10 |
In this example, shipping and duties add only about USD 1.10 per part — around 14% on top of the part price. That ratio is typical for lightweight plastic parts shipped by express in batch quantities, and it is exactly why cnc machining services china remain competitive even after freight is included. For a 5-piece prototype order, the same express parcel might cost USD 60–100 in total, which is why prototypes feel "shipping-heavy" while production batches barely notice it.
The fastest way to a reliable per-part number is a complete RFQ. Include:
A capable factory will also flag cost-saving opportunities in your design — loosening a non-critical tolerance, adjusting a wall thickness, or suggesting an alternative resin can shave a meaningful percentage off the unit price.
ANOK Precision Manufacturing has machined custom plastic and metal parts in Shenzhen, China since 2007, and holds ISO 9001:2015 certification. Our shop runs more than 50 machining centers with 3-axis, 4-axis, and 5-axis capability, holding tolerances down to ±0.002 mm — more than enough headroom for precision plastic components. We machine the full engineering plastics range, from ABS, POM, Nylon, PC, and PMMA through PTFE, PEEK, and ULTEM, supporting everything from one-off prototypes to high-volume production.
Because we are a factory, not a broker, your quote includes direct DFM feedback from our engineers, export-grade packing, and flexible shipping arrangements — express for urgent prototypes, air or sea freight for volume orders. Send your CAD files to info@anok-machining.com and you will receive a detailed, itemized quotation, normally within 24 hours.
So, how much does plastic CNC machining from China cost per part including shipping? For most small-to-medium batches of straightforward parts, expect a landed cost in the single-digit to low-double-digit USD range per piece — with freight and duties typically adding only 10–20% for lightweight plastic components. The parts themselves are cheap to ship; what matters is choosing the right material, ordering sensible quantities, and getting an itemized quote that shows freight separately. Do those three things, and China-based machining delivers real, verifiable savings — not just a low headline number.
