Optical and Lens

At Tan Star Industries (TSI), our bimetallic and precision metal processing capabilities support the optical and lens industry in delivering high-performance components. Our barrels and screws are engineered to ensure dimensional stability, low deformation, and exceptional surface finish — all critical for optical molding and lens fabrication.

Using advanced techniques such as bimetallic centrifugal casting, controlled heat treatment, and surface enhancement, we manufacture parts that maintain tight tolerances even under thermal cycling and continuous usage. This helps optical manufacturers reduce defects, improve yield, and maintain clarity in their lens and optical element production.

Whether for injection molding of optical-grade plastics or precision molding of lens assemblies, TSI is your trusted partner in ensuring consistency, minimizing warpage, and advancing innovation in optical manufacturing.
