Hema Engineering Industries Interview Questions and Answers

Coil gape can be checked using a feeler gauge to measure the distance between the coils.

• Use a feeler gauge to measure the gap between the coils

• Ensure the coil is at room temperature before measuring

• Check for any irregularities or inconsistencies in the coil gape

Core hardness can be checked using various methods such as Rockwell hardness test, Brinell hardness test, and Vickers hardness test.

• Use Rockwell hardness test for quick and easy measurement

• Use Brinell hardness test for larger core samples

• Use Vickers hardness test for small or thin core samples

• Ensure proper calibration of testing equipment

• Follow standard testing procedures for accurate results

Polymer percentage can be checked using techniques like thermogravimetric analysis, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy.

• Use thermogravimetric analysis to measure the change in weight of a sample as it is heated, allowing for calculation of polymer percentage based on weight loss.

• Utilize Fourier transform infrared spectroscopy to analyze the chemical bonds present in...read more

Tool validation involves testing and verifying that a tool or equipment meets its intended purpose and specifications.

• Identify the purpose and specifications of the tool

• Develop a validation plan and protocol

• Perform testing and data analysis

• Document and report results

• Implement corrective actions if necessary

A double action press or tool is a machine that performs two actions in one stroke.

• It can cut and bend metal sheets simultaneously.

• It is commonly used in the automotive industry for stamping car parts.

• The press has two rams that move in opposite directions to perform the two actions.

• It is more efficient and saves time compared to using separate machines for each action.

5S is a workplace organization method that uses a set of tools to create and maintain an organized, clean, and efficient work environment.

• Sort - eliminate unnecessary items

• Set in order - organize remaining items

• Shine - clean and inspect work area

• Standardize - establish procedures for maintaining the first three S's

• Sustain - ensure the first four S's are maintained over time

• Example: labeling tools and equipment, co...read more

The seven QC tools are basic statistical tools used to identify and solve quality problems.

• Check sheets - used to collect data in a structured manner

• Pareto charts - used to identify the most frequent problems

• Histograms - used to show the distribution of data

• Cause-and-effect diagrams - used to identify the root cause of a problem

• Control charts - used to monitor a process over time

• Scatter diagrams - used to show the...read more

GD&T stands for Geometric Dimensioning and Tolerancing. PPAP stands for Production Part Approval Process.

• GD&T is a system of symbols and rules used to specify the geometry of mechanical parts and assemblies.

• PPAP is a set of documents that demonstrate a supplier's ability to meet customer requirements and ensure consistent quality.

• GD&T helps ensure that parts fit together correctly and function properly.

• PPAP includ...read more
