How to use the Plastic Design Guide
- Refer to the Design Considerations at the bottom of this page. Consider whether each item on the checklist is a factor in the application or affects performance requirements for the component design.
- Select the categories that have the greatest affect on your application.
- Review the materials in the Free Plastic Properties Handbook and make a list of possible material candidates.
- Contact our technical support to discuss options or ask additional questions.
Plastic Machining Design Considerations
- Thermosensitivity – tolerance can change in different temperature conditions
- Sensitivity to humidity and hygroscopic absorption affects tolerance
- Sensitivity to chemicals and oils
- Notch sensitive corners and square ID’s
- High loads
- High impact
- Fatigue loading or cycle loading requires consideration of flexing, deflecting, and compression
- Temperature – max/min extent of time
- Electrical considerations such as insulating properties
- Wear resistance or abrasion resistance
- Dimensional shape retention (load, cold flow, temperature)
- Regulatory requirements (FDA, UL, etc.)
- Appearance (color, texture)
- Optical requirements
- Outdoor use
Now that you’ve identified the important factors in your application, evaluate material specs in the Plastic Properties Handbook and select your material!
