The price of CNC machined ABS isn’t fixed—it ranges from 20 RMB/piece for simple parts A 1,000 RMB/piece for complex, Componenti ad alta precisione—shaped by material costs, machining complexity, dimensione batch, e altro. This guide breaks down the core price drivers, provides practical references, condivide suggerimenti per risparmiare sui costi, and answers common questions to help you make informed decisions.
1. 6 Core Factors That Affect the Price of CNC Machined ABS
Ogni componente del prezzo è legato a fattori tangibili, dai costi delle materie prime alle esigenze di post-elaborazione. Di seguito è riportata una ripartizione dettagliata con numeri reali per illustrarne l’impatto:
(1) ABS Material Cost
Il costo del materiale costituisce la base del prezzo totale. La resina ABS standard è conveniente, ma gradi speciali (PER ESEMPIO., retardante fiamma, cibo-cibo) aggiungere al costo:
| Tipo di grado ABS | Fascia di prezzo (RMB/kg) | Caratteristiche chiave | Applicazioni tipiche |
| ABS standard | 10 ~ 20 | Buona macchinabilità, resistenza agli urti di base | Prototipi generali, shell non critiche |
| Abs-retardante di fiamma | 20 ~ 35 | Soddisfa gli standard di sicurezza antincendio (PER ESEMPIO., Ul94 v-0) | Recinti elettronici (PER ESEMPIO., conchiglie del router) |
| ABS per uso alimentare | 25 ~ 40 | Non tossico, conforme a FDA/GB 4806 | Parti a contatto con gli alimenti (PER ESEMPIO., interni di piccoli elettrodomestici) |
| ABS ad alta tenacità | 30 ~ 50 | Maggiore durata per un uso ripetuto | Parti funzionali (PER ESEMPIO., cerniere giocattolo, maniglie degli strumenti) |
Esempio: A 100g simple part made with standard ABS costs 1–2 RMB in material (10–20 RMB/kg × 0.1kg). The same part made with food-grade ABS would cost 2.5–4 RMB in material—2.5x more.
(2) Machining Cost (Attrezzatura + Lavoro)
Machining cost is the largest variable, combining equipment hourly rates and labor fees. It depends on the type of CNC machine and operator skill:
Equipment Hourly Rates
| Tipo di macchina CNC | Hourly Rate (RMB/Hour) | Livello di precisione | Meglio per |
| Ordinary 3-Axis Machining Center | 60 ~ 150 | Medio | Parti semplici (PER ESEMPIO., piatti piatti, basic holes) |
| High-Precision 3-Axis Machine | 150 ~ 300 | Alto | Parti con tolleranze strette (± 0,05 mm) |
| 5-Axis Machining Center | 500 ~ 1,000 | Ultra-Alto | Complex curved parts (PER ESEMPIO., Shells personalizzate) |
Costi del lavoro
- Operator Salary: 50 ~ 100 RMB/ora (varies by region—coastal areas like Guangdong have lower rates due to competition).
- Programming Fee: 200 ~ 1,000 RMB for complex parts (PER ESEMPIO., multi-surface shells) that require custom G-code; simple parts often include programming in the hourly rate.
Esempio: A simple ABS part taking 1 hour on an ordinary 3-axis machine (80 RMB/ora) con a 60 RMB/hour operator costs 140 RMB in machining labor—far more than the material cost.
(3) In parte complessità
Complexity directly increases machining time and skill requirements, pushing prices higher. Below is how complexity impacts per-piece costs:
| Livello di complessità | Tratti chiave | Tempo di lavorazione (Per pezzo) | Fascia di prezzo (RMB/Piece) |
| Semplice | Superfici piane, no curves, 1–2 holes | 0.5 ~ 1 ora | 20 ~ 50 |
| Medio | Più buchi, simple curves, pareti sottili (≥2mm) | 1 ~ 3 ore | 50 ~ 200 |
| Alto | Complex curved surfaces, pareti sottili (<2mm), porous structures | 3 ~ 8 ore | 200 ~ 1,000 |
Esempio: A simple 10cm×10cm ABS plate (10mm di spessore) prende 0.5 hours to machine and costs 20–50 RMB. A curved ABS shell with 5 holes and thin walls takes 4 hours and costs 200–500 RMB—5–10x more.
(4) Dimensione batch
Batch size unlocks volume discounts, as fixed costs (programmazione, impostare, trial cuts) sono distribuiti in più parti. The larger the order, the lower the unit price:
| Dimensione batch | Discount vs. Single Piece | Esempio: Simple ABS Part (Original Price: 50 RMB/Piece) | Unit Price (RMB/Piece) |
| Single Piece/Small Batch (1–10) | 0% (No Discount) | 50 × 10 = 500 RMB (totale) | 50 |
| Medium Batch (11–100) | 10 ~ 30% | 50 × 50 × 0.8 = 2,000 RMB (totale) | 40 |
| Grande lotto (>100) | 30 ~ 60% | 50 × 200 × 0.5 = 5,000 RMB (totale) | 25 |
Consiglio chiave: Even small batch increases (PER ESEMPIO., da 5 A 20 pezzi) can cut unit costs by 10–20%. Per esempio, 20 simple parts cost 40 RMB/piece instead of 50 RMB—saving 200 RMB total.
(5) Requisiti di post-elaborazione
Basic CNC-machined ABS parts have a matte finish, but additional treatments add to the price. Common post-processing steps and their costs:
| Passaggio di post-elaborazione | Costo (RMB/Piece) | Scopo |
| Lucidare | 10 ~ 30 | Superficie liscia (reduces roughness from Ra 1.6μm to Ra 0.8μm) |
| Painting/Oil Spraying | 20 ~ 50 | Add color or protective coating |
| Stampa sullo schermo di seta | 15 ~ 40 | Add logos or text (PER ESEMPIO., control panel labels) |
| Elettroplazione | 30 ~ 80 | Add metallic finish (PER ESEMPIO., chrome-like coating) |
Esempio: A basic ABS part costs 30 RMB. Adding polishing (20 RMB) and silk screen printing (25 RMB) raises the total to 75 RMB—2.5x more.
(6) Regional Differences
Prices vary by region due to labor and competition levels:
- Aree costiere (Guangdong, Zhejiang): Lower prices (10–20% cheaper than inland) due to high competition and mature supply chains. Per esempio, a medium-complexity part costs 50–180 RMB vs. 60–220 RMB inland.
- Central/Western Regions: Slightly higher prices, but may offer faster delivery for local clients.

Domande frequenti
- Why does a 5-axis machined ABS part cost so much more than a 3-axis part?
5-axis machines offer ultra-high precision (± 0,02 mm) and can machine complex curved surfaces in one setup—eliminating the need for multiple clampings. Tuttavia, they’re more expensive to purchase (10–20x cost of 3-axis machines) e mantenere, leading to higher hourly rates (500–1,000 RMB/hour vs. 60–150 RMB/hour for 3-axis). This translates to 2–5x higher part prices.
- How much does flame-retardant ABS add to the total price compared to standard ABS?
Flame-retardant ABS costs 20–35 RMB/kg vs. 10–20 RMB/kg for standard ABS—2x more in material cost. For a 100g part, this adds 1–1.5 RMB to the material cost. If the part requires machining, the total price increases by 5–15% (PER ESEMPIO., 50 RMB standard part becomes 55–58 RMB).
- Can I get a discount if I provide my own ABS material?
Yes—most suppliers offer a 5–15% discount if you supply the ABS resin. Per esempio, UN 100 RMB part becomes 85–95 RMB. Tuttavia, ensure your material is suitable for CNC machining (PER ESEMPIO., no impurities) to avoid machining defects that require rework (which could erase the discount).
