• Shrinkage: Adjust pouring temperature, mold design, or alloy composition.

7. Describe the different types of casting processes used for tin and their respective advantages and disadvantages.

Sand casting

• Advantages: Low cost, versatile.
• Disadvantages: Rough surface finish, dimensional limitations.

Investment casting

• Advantages: High precision, smooth surface finish.
• Disadvantages: Expensive, complex process.

8. How do you ensure the quality of tin castings?

• Follow proper pouring and casting techniques.
• Inspect castings for defects using visual inspection or non-destructive testing.
• Maintain equipment and tools regularly.

9. What are the key properties of tin that make it suitable for casting?

• Low melting point.
• Excellent fluidity.
• Resistance to corrosion.

10. Describe your experience with different tin alloys and their applications.

I have experience working with a range of tin alloys, including pewter, solder, and babbitt. Each alloy has its own unique properties and applications. For example, pewter is used for decorative items, solder for electrical connections, and babbitt for bearings.
