CNC Machining Plastic Material
Characteristics

> Lightweight And High specific strength: Density Usually 0.9-1.6g/Cm³(Only 1/8-1/6 That of Steel), Some Reinforced Materials (Such As Carbon Fiber Filled Nylon) Tensile Strength Up To 200MPa.

> Excellent Chemical stability: Far Exceeds Metals In Acid/Alkali/Salt Corrosion Resistance (Such as PTFE Can Withstand Aqua Regia).

> Insulation And Vibration Reduction: Volume Resistivity>10¹²Ω·Cm(PEEK), Damping Coefficient 0.05-0.3 (Better Than Metals).

> Low Friction Coefficient:POM Friction Coefficient 0.14,PTFE Only 0.04(Self-Lubricating Properties).

> Machining Challenges:
1. High Coefficient Of Thermal Expansion (5-10 Times That of Steel), Easy To Produce Dimensional Deviation.
2. Poor Thermal Conductivity (Only 1/100 That Of Metal), Cutting Heat Can Cause Material Softening.
3. Low Elastic Modulus (1.5-4GPa), Thin-Walled Parts Are Prone To Deformation.
4.Severe Electrostatic Adsorption (Requires Grounding Treatment).

Plastic Material Surface Treatment Process
1.Chemical treatment:
◆ Chromium etching (improves coating adhesion of ABS/PC).
◆ Plasma treatment (improves printing performance of PE/PP).
2.Coating process:
◆ Painting (polyurethane paint for ABS).
◆ Vacuum coating (aluminum film for PMMA reflectors).
◆ Laser engraving (depth controllable marking).
3.Mechanical treatment
◆ Sandblasting (matte surface).
◆ Polishing (RaO.lum mirror effect).
4.Functional treatment:
◆ Conductive coating (carbon nanotube treatment for anti-static).
◆ Biological coating (hydroxyapatite for medical implants).
