Godrej & Boyce Manufacturing Interview Questions, Process, and Tips

Q1. Thermal expansion and Young's modulus and mfg process of PDC and press tool?
Ans. 
Thermal expansion affects PDC and press tool manufacturing due to Young's modulus.
• Thermal expansion can cause dimensional changes in materials during manufacturing processes.

• Young's modulus is a measure of a material's stiffness and resistance to deformation.

• PDC (Polycrystalline Diamond Compact) is a material commonly used in cutting tools due to its hardness and wear resistance.

• Press tools are used in metal forming pr...read more

Q2. What's the best simulation of shrinkage in thermal expansion of casting ?
Ans. 
The best simulation of shrinkage in thermal expansion of casting is achieved through finite element analysis (FEA).
• Finite Element Analysis (FEA) is commonly used to simulate shrinkage in thermal expansion of casting.

• FEA software allows for accurate prediction of shrinkage and deformation during the casting process.

• By inputting material properties, boundary conditions, and thermal gradients, FEA can provide valuable ins...read more

Q3. How to correction casting thickness within model?
Ans. 
To correct casting thickness within a model, adjust the design parameters and re-run simulations.
• Modify the CAD model to adjust the thickness of the casting.

• Update the material properties and casting parameters in the simulation software.

• Run simulations to analyze the effects of the changes on the casting quality.

• Iterate the process until the desired casting thickness is achieved.

• Consult with design engineers and casti

Q4. How to calculate flow rate ?
Ans. 
Flow rate can be calculated by dividing the volume of fluid passing through a pipe or channel by the time it takes to pass.
• Flow rate = Volume / Time

• Units of flow rate are typically liters per minute (L/min) or cubic meters per second (m^3/s)

• Flow rate can be measured using flow meters or calculated based on known parameters such as pipe diameter and fluid velocity

Q7. How to increase molten metal pressure in casting area?
Ans. 
To increase molten metal pressure in casting area, adjust the pouring rate, increase the height of the pouring basin, and use a pressurized system.
• Adjust the pouring rate to control the flow of molten metal into the casting area.

• Increase the height of the pouring basin to create more pressure when the metal is poured.

• Use a pressurized system such as a vacuum or pressure casting method to increase the pressure of the mo

Q2. Definition of Standard deviations as per IS 456 2000.
Ans. 
Standard deviations in IS 456 2000 are used to measure the variability of concrete strength test results.
• Standard deviations are used to quantify the scatter of individual test results around the average strength value.

• They help in assessing the consistency and reliability of concrete mixtures.

• IS 456 2000 provides guidelines on how to calculate standard deviations based on test results.

• For example, if the average compr...read more
