I applied via Company Website and was interviewed in Apr 2024. There were 5 interview rounds.
Tool & DIE makers typically use materials like steel, aluminum, and carbide in die casting.
Steel is commonly used for its durability and heat resistance.
Aluminum is often used for its lightweight properties.
Carbide is used for its hardness and wear resistance.
Other materials like copper, brass, and titanium may also be used depending on the specific requirements of the die casting process.
To grind drills, use a bench grinder with a fine grit wheel, ensure the drill is securely held in a vise, and maintain a consistent angle and pressure while grinding.
Use a bench grinder with a fine grit wheel for precision grinding
Securely hold the drill in a vise to prevent movement during grinding

Tolerance is the allowable variation in a dimension. There are two types of tolerance: unilateral and bilateral.
Tolerance is the difference between the maximum and minimum limits of a dimension that is acceptable.
Unilateral tolerance allows variation in only one direction, while bilateral tolerance allows variation in both directions.
Tolerance is important in manufacturing to ensure that parts fit together properly and...

Wrinkles occur due to excessive stress on the material during the forming process.
Wrinkles are caused by compressive stresses in the material.
They occur when the material is stretched or bent too much in a localized area.
Factors that contribute to wrinkles include material thickness, bend radius, and lubrication.
Wrinkles can be prevented by adjusting the forming process parameters or using a different material.
Examples...

Crack problems in tool and die making can occur due to various reasons.
Cracks can occur due to improper heat treatment of the material.
Excessive stress on the tool can also lead to cracks.
Improper design or manufacturing process can also be a cause.
Cracks can also occur due to wear and tear over time.
Regular maintenance and inspection can help prevent crack problems.
Dent mark problems occur due to various reasons such as improper handling, tool wear, and material defects.
Improper handling of the tool or material can cause dent marks.
Tool wear can also lead to dent marks on the material.
Material defects such as impurities or inconsistencies can result in dent marks.
Dent marks can also occur due to incorrect tool selection or setup.
Proper maintenance and inspection of tools can help
