Tool and Die Making
Tool and die making is the first and most critical step in the investment casting process. In this stage, precision dies are designed and manufactured using advanced CAD/CAM and CNC machining techniques. These dies are created by considering shrinkage factors of both wax and metal to ensure accurate final dimensions. The quality of the die directly impacts the accuracy, surface finish, and repeatability of the casting.
High-grade materials like aluminum or steel are typically used to ensure durability and long tool life. Proper design also ensures smooth wax injection and easy removal of wax patterns. This stage lays the foundation for producing high-quality cast components with tight tolerances and consistency.
