For moldmakers who wish they could simulate the molding process without having to build a prototype mold first, Sigmasoft software, designed for 3D injection molding process simulation, may be the ...

Precision injection-molded plastic optical lenses are extensively utilized in imaging optical systems. The residual stress and surface deformation produced during the injection molding of plastic ...

This paper presents a novel method to eliminate halo gloss transition surface defects commonly found on large-scale injection-molded parts. Due to the increasing importance of product appearance and ...
