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

Q6. Mold temperature depend upon?
Ans. 
Mold temperature depends on various factors such as material type, cooling system, injection speed, and mold design.
• Material type: Different materials require different mold temperatures for optimal results.

• Cooling system: The efficiency of the cooling system affects the mold temperature.

• Injection speed: Faster injection speeds may require higher mold temperatures to prevent defects.

• Mold design: The design of the mold ...read more

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. Explain normalization
Ans. 
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
• Normalization involves breaking down data into smaller, more manageable parts.

• It helps in reducing data redundancy by storing data in a structured way.

• Normalization ensures data integrity by avoiding anomalies like insertion, update, and deletion anomalies.

• There are different levels of normalization such as 1NF...read more
