4. Guide Pins and Bushings To maintain alignment between the punch and die, guide pins and bushings are employed. They ensure that the punching action is precise and that the components remain aligned during operation. This alignment is critical for achieving high-quality finished products.

Aluminum die casting, for instance, is particularly popular for its lightweight nature combined with excellent strength, corrosion resistance, and thermal conductivity. Zinc die casting, known for its superior finishing and high production rates, is frequently used for smaller components like housings and brackets. Magnesium, being the lightest structural metal, is ideal for applications requiring weight reduction, while copper alloys are chosen for their excellent electrical conductivity.
