transparent mold

This portfolio piece showcases a transparent acrylic mold used for flow analysis. By filling the mold with water, engineers can directly observe the internal flow of material — making it a practical tool for identifying the causes of molding defects such as short shots and blowholes.

Why Acrylic (PMMA)?
Acrylic resin offers a transparency rate of approximately 93%, which exceeds that of glass (approximately 90%). This exceptional clarity makes it ideal for models requiring precise visibility of internal shapes and flow behavior, as well as applications such as lens cut models and display monuments.

INAC’s Strengths in Acrylic Machining
INAC machines acrylic using a proprietary end mill developed in collaboration with a leading blade manufacturer. This approach delivers several key advantages:

• No manual polishing required — eliminating a process that can compromise dimensional accuracy
• High machining precision, enabling faithful reproduction of detailed shapes such as lens cuts
• Dry cutting method — minimizing adhesion of chemical substances from cutting fluid to the workpiece
• High transparency reproduced directly from machining, without secondary finishing

Applications

• Flow analysis models (internal visualization for flow behavior and defect diagnosis)
• Lens cut models and optical components
• Display and exhibition models requiring intricate design detail
