Machining HDPE Plastic Properties
Tensile Strength, Yield (MPa) | Elongation at Break | Hardness | Impact Strength | Heat Deflection | Heat Deflection Temperature | Melting Point |
---|---|---|---|---|---|---|
20–37 MPa | 100–600% | R60–R100 | 80–120 J/m | 70–90°C | 50–70°C | 130–137°C |
- The above parameters represent the baseline performance of the materials. Actual application should be dynamically optimized based on specific working conditions.

Advantages & Disadvantages of HDPE CNC Machining
Advantages
- Excellent machinability – easy to cut and shape with CNC tools
- High chemical resistance – performs well in corrosive environments
- Moisture & impact resistance – ideal for outdoor and fluid applications
- Lightweight & durable – strong yet low density for efficient production
- Low cost – affordable for both prototyping and production runs
Disadvantages
- Lower dimensional stability – may require tighter process control
- Soft surface – more prone to scratches compared to harder plastics
- Poor UV resistance – degrades with long-term sun exposure unless stabilized
- Thermal expansion – may require design compensation in precision assemblies
Surface Finishing Options for CNC Machined HDPE Parts
Standard finish with visible tool marks; suitable for functional prototypes and internal components.
Uses abrasive media to create a uniform matte or satin finish; also improves coating adhesion on plastic or metal surfaces.
Adds logos, text, or identification marks via silk screen or pad printing, ideal for branding or part tracking.
Removes machining marks and evens out surface texture; ideal for prototypes and parts where appearance is not critical.
Painting and powder coating provide colorful, durable, and corrosion-resistant finishes.
Deposits metal layers such as nickel or chrome on parts, improving wear resistance, conductivity, and aesthetic quality.
Produces a smooth, glossy finish; commonly applied to plastics like PC or PMMA for enhanced clarity and premium look.
Chemical treatment for ferrous metals, creating a dark, corrosion-resistant surface with minimal thickness.
Electrochemical process for aluminum that enhances corrosion and wear resistance, with options for colored finishes.
