Arf Design Trainee Design Engineer Interview Questions and Answers

Types of plastics used in die design include thermoplastics, thermosets, and elastomers.

• Thermoplastics can be melted and reformed, such as ABS and polyethylene

• Thermosets are set during molding and cannot be remelted, like epoxy and phenolic resins

• Elastomers are flexible and rubber-like, such as silicone and neoprene

The least count of a calibration instrument refers to the smallest measurement that can be accurately read or displayed by the instrument.

• Least count is determined by the precision of the instrument's scale or digital display.

• For example, a caliper with a least count of 0.1 mm can accurately measure to the nearest 0.1 mm.

• Software information calibration involves ensuring that the software used to read and record measur...read more
