EspañolPlastic Injection Mold Design Guidelines
wall thickness
The wall thickness of a thermoplastic part depends on several factors. These factors include the type of thermoplastic used, mechanical stress on the part, electrical performance requirements (if any), and more.
The following are general rules of thumb:
The main wall thickness of the part should be uniform
Avoid rapid thickness transitions. Instead, use a gradient thickness transition of 3 to 1.
The gate for injecting the thermoplastic should be in the thicker section
Wall Thickness Considerations
When designing plastic parts, several factors should be considered to determine the wall thickness of the part. These factors include:
Application requirements such as:
Structural strength
fatigue
deflection
electrical load
The formability of parts includes
Part size
Material flows to the narrowest point
Number and location of doors
Design requirements for registration bodies such as UL or RTI
