CNC Plastic Materials & Their Application Parts
Below are the most common global plastic standards used in CNC machining, each influencing cnc plastic machining prototype cost.
ABS (Acrylonitrile-Butadiene-Styrene)
Features: Easy to machine, cost-effective, good toughness
Typical machined application parts:
- Consumer electronics housings
- Remote-control shells
- Automotive dashboard prototype pieces
- Light structural brackets
- General-purpose enclosures
ABS often results in one of the lowest cnc plastic machining prototype cost ranges.
PC (Polycarbonate)
Features: High strength, optical clarity
Typical machined application parts:
- Transparent protective covers
- Aerospace indicator windows
- Machine vision housings
- Medical display covers
- Impact-resistant guards
Higher toughness slightly increases cnc plastic machining prototype price.
POM / Acetal / Delrin
Features: High precision, low friction, excellent stability
Typical machined application parts:
- Precision gears
- Bearings & bushings
- Robotic sliders
- Valve components
- Mechanical guide blocks
POM provides excellent tolerances with moderate cnc plastic machining prototype cost.
Nylon (PA6, PA66)
Features: Strong, durable, excellent impact resistance
Typical machined application parts:
- Wear pads
- Pulley wheels
- Cable clamps
- Industrial spacers
- Structural sliders
Moisture absorption may affect tolerance, influencing cnc plastic machining prototype price.
PTFE (Teflon)
Features: Near-zero friction, extreme chemical resistance
Typical machined application parts:
- Lab equipment components
- Valve seats
- Insulator washers
- Fluid sealing rings
- Anti-corrosion fittings
PTFE’s softness requires slower machining → higher cnc plastic machining prototype cost.
PEEK (Polyetheretherketone)
Features: Aerospace-grade engineering plastic, high-temperature capability
Typical machined application parts:
- High-temperature bushings
- Aircraft and UAV housings
- Semiconductor tooling
- Medical trial implants
- Oil & gas structural parts
PEEK machining difficulty makes it one of the highest cnc plastic machining prototype price tiers.
PMMA (Acrylic)
Features: Excellent transparency and optical polishability
Typical machined application prototype parts:
- Indicator covers
- Light guides
- Display windows
- Optical prototype blocks
- Transparent testing housings
Requires careful machining to avoid cracks.
UHMW-PE
Features: Extremely tough, high wear resistance
Typical machined application parts:
- Conveyor wear strips
- Dock bumpers
- Impact plates
- Food-grade machinery components
- Sliding structural pads
Toughness leads to higher cnc plastic machining prototype cost.
PEI (Ultem)
Features: High heat resistance, high strength
Typical machined application parts:
- Semiconductor machine brackets
- Aerospace insulation housings
- High-temp connectors
- Medical device components
- Electrical insulators
Often used where strength is critical.
PVC
Features: Chemically stable, inexpensive, well-balanced
Typical machined application parts:
- Fluid-handling fittings
- Prototype valves
- Electrical junction housings
- Pump system components
- Outdoor enclosures
PVC generally offers low cnc plastic machining prototype price.
PP (Polypropylene)
Features: Chemical-resistant, flexible, lightweight
Typical machined application parts:
- Laboratory caps and connectors
- Medical consumable prototypes
- Fluid-handling system parts
- Light-duty hinges
- Industrial testing fittings
A cost-friendly choice for chemical applications.
Key Factors Affecting CNC Plastic Machining prototype Cost
1. Geometry complexity
Thin walls, deep pockets, small radii, undercuts → higher cnc plastic machining prototype cost.
2. Tolerance requirements
- ±0.005 inch (standard plastics)
- ±0.002 inch (POM/PC)
- ±0.001 inch (PEEK precision parts)
Higher precision = higher cnc plastic machining prototype price.
3. Machine type
- 3-axis (lowest cost)
- 4-axis (medium)
- 5-axis (highest cost)
4. Batch size
Prototypes cost more per piece; volume orders reduce cost.
5. Surface finishing
Polishing, sanding, vapor polishing (Acrylic), painting → increases cnc plastic machining prototype cost.
Typical CNC Plastic Machining Prototype Price Ranges
Simple parts (ABS/POM)
$5–$20 per piece
Medium-complexity parts (PC/Nylon/PMMA)
$20–$80 per piece
High-performance parts (PEEK/PTFE/PEI)
$80–$300+ per piece
These values reflect average cnc plastic machining prototype price across global markets.
