Plastic Part Design Guidelines For Wall Thickness

Plastic Part Design Guideline For Wall Thickness


When a part design engineer need to concern making a plastic part there can 

be a knowledge gap in making sure the CAD model is properly designed for this manufacturing 

process.  The wall thickness is one of the important points.


    

  • Find out what raw material is the plastic part will be and check the general thicknss for it

  • Maintain a uniform wall thickness throughout your parts design

  • Thick wall design is prone to warp or other cosmetic issues

  • 10% Increase in wall thickness will provide 33% more stiffness with most materials.

  • Thick wall areas can sink, warp or contain voids resulting in undesired defects.

  • Using ribs can help to reduce thick wall sections while still giving the part strength.

Firstly, check with the material supplier before designing your part.
