I applied via Naukri.com and was interviewed in Sep 2023. There were 3 interview rounds.
Draft angles are used in plastic to facilitate easy ejection of the molded part from the mold.
Draft angles help prevent the part from getting stuck in the mold during ejection
They reduce friction between the part and the mold walls
Draft angles improve the overall quality and consistency of the molded part
Common draft angles range from 1 to 3 degrees, depending on the material and design
Shrinkage in plastic refers to the reduction in size of a plastic part during the cooling process after molding.
Shrinkage occurs due to the cooling and solidification of the molten plastic material.
It is important to account for shrinkage when designing molds for plastic parts.
Factors affecting shrinkage include the type of plastic material, mold temperature, and cooling rate.
Examples of plastics with high shrinkage in...
To prevent plastic defects, design engineers use methods such as mold flow analysis, material selection, gate design optimization, and part geometry considerations.
Perform mold flow analysis to identify potential issues before production.
Select the appropriate plastic material based on the requirements of the part.
Optimize gate design to ensure proper filling and packing of the mold.
Consider part geometry to minimize s...
Design library in SolidWorks is a feature that allows users to store and reuse commonly used parts, features, and assemblies.
Design library provides easy access to standard components like screws, nuts, bolts, etc.
Users can drag and drop items from the design library directly into their designs.
It helps in saving time by reusing pre-designed components instead of creating them from scratch.
Design library can be customi...
The joining of 2 sheet metal processes can be achieved through methods like welding, riveting, adhesive bonding, or clinching.
Welding: involves melting the edges of the two sheet metals and fusing them together.
Riveting: involves using metal fasteners to join the two sheet metals together.
Adhesive bonding: involves using a strong adhesive to bond the two sheet metals together.
Clinching: involves deforming the edges of
Various methods such as injection molding, blow molding, extrusion, and rotational molding are used in plastic manufacturing.
Injection molding: molten plastic is injected into a mold to create a part
Blow molding: air pressure is used to expand molten plastic into a mold
Extrusion: plastic is melted and forced through a die to create a continuous profile
Rotational molding: powdered plastic is rotated in a mold until it c
Plastic design consideration involves material selection, part geometry, manufacturability, and environmental impact.
Material selection based on properties like strength, flexibility, and temperature resistance.
Consideration of part geometry for moldability, assembly, and functionality.
Ensuring manufacturability by designing for injection molding, extrusion, or other processes.
Addressing environmental impact by choosin...
Stress is the internal resistance of a material to deformation, while pressure is the force exerted on a surface.
Stress is a measure of the internal forces within a material, while pressure is a measure of the external force applied to a surface.
Stress is a scalar quantity, while pressure is a vector quantity.
Stress is typically measured in units of force per unit area (such as N/m^2 or Pa), while pressure is also meas...
Root cause analysis is a systematic process of identifying the underlying cause of a problem or issue.
Root cause analysis helps in understanding the fundamental reason behind a problem.
It involves investigating the symptoms, identifying potential causes, and determining the primary cause.
By addressing the root cause, it is possible to prevent the problem from recurring.
Root cause analysis techniques include 5 Whys, Fis...

Renloyds number is a dimensionless number used in fluid mechanics to characterize the flow of a fluid over a surface.
Renloyds number is defined as the ratio of inertial forces to viscous forces in a fluid flow.
It is used to determine the type of flow (laminar or turbulent) that occurs over a surface.
Renloyds number is calculated using the formula: Re = (ρ * V * L) / μ, where ρ is the density of the fluid, V is the velo...
