Samvardhana Motherson Group Tool & DIE Maker Interview Questions and Answers

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...read more

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

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...read more

CRDI stands for Common Rail Direct Injection, a fuel injection technology used in diesel engines.

• CRDI engine uses a common rail to supply fuel to the injectors at high pressure.

• It allows for precise control of fuel injection and improves fuel efficiency.

• CRDI engines are commonly used in diesel cars, trucks, and heavy machinery.

• Hyundai, Kia, and Tata Motors are some of the manufacturers that use CRDI engines in their ve

CRDI engine uses common rail technology while TDI engine uses turbocharging technology.

• CRDI stands for Common Rail Direct Injection while TDI stands for Turbocharged Direct Injection.

• CRDI engine uses a common rail to supply fuel to the injectors while TDI engine uses a turbocharger to increase the air intake.

• CRDI engine provides better fuel efficiency and lower emissions while TDI engine provides better power and torqu...read more
