To determine that a certain shell part or the parts of it do not belong to the “precision” category, several aspects are considered to include the design parameters, the tolerance levels of its fabrication, the type of material used and the functionality of the shell part in its intended application and quality assurance.
How do you determine if a shell part meets the definition of precision? What are the evaluation criteria?
1. Dimensional accuracy:
When it comes to assembling Precision Shell Plastic Parts, there are strict demands on design drawings and tolerance. In physically inspecting the parts, it is recommended that one makes use of measuring devices of high accuracy in order to confirm that the sizes of the part such as length, width, thickness, diameter of holes, angles among others are as per the design drawings.
2. Surface quality:
There are other parameters that determine the precision of a surface and they include the surface finish, surface roughness an…
