Design Criteria

Plastic  machined parts are designed differently than molded pats. EPP can help you determine which is best suited for your application.

Review the following items and identify any issues which could affect the function of your part in its application.

• Thermosensitivity - tolerance can change in different temperature conditions
• Sensitivity to humidity and water atmosphere (hydroscopic) affects tolerance
• Sensitivity to chemicals and oils
• Notch sensitive-corners and square ID's
• Tolerances
• High loads
• High impact
• Fatigue loading or cycle loading
  • Flexing
  • Deflecting
  • Compression
• Temperature
• Electrical considerations (insulating properties, etc.)
• Wear resistance or abrasion resistance
• Dimensional shape retention
  • Load
  • Cold Flow
  • Temperature
• Regulatory requirements (FDA, UL, etc.)
• Appearance (color, texture)
• Optical requirements
• Outdoor use
