The wall thickness of injection-molded plastic products has a great impact on quality. If the wall thickness is too small, the flow resistance is large, and it is difficult for large and complex plastic parts to fill the cavity. As a plastic product manufacturer, we believe that the minimum size of the wall thickness of plastic parts must meet The following aspects are required:

1.Have sufficient strength and stiffness;
2.Can withstand the impact and vibration of the demoulding mechanism when demoulding;
3.It can bear the fastening force during assembly.

The wall thickness of plastic products first depends on the use requirements of plastic products: including the strength of parts, quality cost, electrical performance, dimensional stability, and assembly, etc. Generally, wall thicknesses have empirical values, which can be determined by referring to similarities.

 

a. The wall thickness of plastic products processed in injection molding should be as uniform as possible to avoid too thin, too thick and abrupt changes in wall thickness. If the plastic parts require certain wall thickness changes, a gradual or circular transition should be used, otherwise it will cause shrinkage. Deformation of plastic parts, affecting the strength of plastic parts, affecting the fluidity during injection molding and other molding process problems.

b. The wall thickness of plastic parts is generally in the range of 1-5mm. The commonly used value is 2-3mm.

 


c. The minimum wall thickness of common plastic parts and recommended value of common wall thickness: (mm)


d. Try not to design the ribs and screw columns too thick. Generally, it is recommended to take half of the body wall thickness, otherwise it is easy to cause appearance problems such as microcosms.


e. Try not to design the part as a separate flat plate, the size is very small, otherwise the deformation will cause the part to be uneven.

As a manufacturer of plastic products, we have more than 10 years of experience. If you need to make plastic products, please contact us.
