Samvardhana Motherson Auto Component Design Engineer Interview Questions and Answers

There are seven main categories of plastic materials.

• Thermoplastics

• Thermosets

• Elastomers

• Composites

• Biodegradable plastics

• Engineering plastics

• High-performance plastics

Plastic rib thickness standard varies depending on the application and material used.

• Plastic rib thickness is typically between 0.5mm to 5mm.

• Thicker ribs provide more strength but may increase material usage and cost.

• Thinner ribs are more cost-effective but may be prone to warping or breaking.

• Consider the material properties and intended use when determining rib thickness.

• Consult industry standards and guidelines for s

There are three main types of defects in plastic: surface defects, physical defects, and chemical defects.

• Surface defects include scratches, sink marks, and flow marks.

• Physical defects include bubbles, voids, and warping.

• Chemical defects include discoloration, degradation, and contamination.

Preventing plastic defects involves proper material selection, design optimization, and quality control measures.

• Selecting the right type of plastic for the application

• Optimizing the design to minimize stress concentrations

• Implementing proper molding techniques and parameters

• Conducting thorough quality control inspections

• Training staff on proper handling and storage of plastic materials

I have experience working with various tonnage molding machines, including 50-ton, 100-ton, and 200-ton machines.

• 50-ton molding machine

• 100-ton molding machine

• 200-ton molding machine

Draft angle in plastic is the degree of taper or slope applied to the vertical walls of a plastic part to facilitate its ejection from the mold.

• Draft angles are typically recommended to be between 1-3 degrees for most plastic parts

• Draft angles help prevent the part from getting stuck in the mold during ejection

• Examples of draft angles include adding a slight taper to the sides of a plastic cup or the walls of a plastic

Parametric modelling is a design approach where the model is defined by a set of parameters and rules that govern its shape and size.

• Uses parameters to define the shape and size of the model

• Allows for easy modification of the design by changing parameters

• Enables creation of complex designs with interconnected features

• Commonly used in CAD software like SolidWorks and Autodesk Inventor

Plastic defects can be solved by identifying root causes, adjusting processing parameters, using quality materials, and implementing proper maintenance.

• Identify root causes of defects such as improper molding conditions or poor material quality

• Adjust processing parameters like temperature, pressure, and cooling rate to optimize production

• Use high-quality materials to ensure consistency and durability of the final produ...read more
