Ghatge Patil Industries Design Engineer Interview Questions and Answers

Careful consideration of material selection, part geometry, draft angles, and tooling design is essential for designing die casted parts.

• Select the appropriate material based on the desired properties and cost-effectiveness

• Design parts with uniform wall thickness to prevent defects like porosity

• Incorporate draft angles to facilitate easy ejection from the mold

• Avoid sharp corners and complex geometries that can lead to ...read more

Common defects in plastic parts include sink marks, warping, flash, and short shots.

• Sink marks: caused by uneven cooling or thick sections in the part

• Warping: caused by uneven cooling or internal stresses in the material

• Flash: excess material around the edges of the part due to poor mold design or excessive injection pressure

• Short shots: incomplete filling of the mold cavity resulting in a part with missing sections

Gears or transmission are mechanical components used to transfer power from one part of a machine to another.

• Gears are toothed wheels that mesh together to transmit motion and power.

• They can change the speed, torque, and direction of a power source.

• Types of gears include spur gears, helical gears, bevel gears, and worm gears.

• Transmissions are systems that use gears to control the power and speed of a vehicle.

• They can b...read more

A simply supported beam is a beam supported at both ends with no moment resistance.

• Draw a straight horizontal line to represent the beam

• Add two vertical lines at each end to represent the supports

• Label the supports as 'A' and 'B'

• You can add a distributed load or point load for additional detail
