Rane Brake Lining Junior Design Engineer Interview Questions and Answers

The types of lacquer used on lens and housing include acrylic lacquer, polyurethane lacquer, and epoxy lacquer.

• Acrylic lacquer is commonly used on lens and housing due to its high transparency and UV resistance.

• Polyurethane lacquer provides excellent durability and chemical resistance, making it suitable for lens and housing.

• Epoxy lacquer offers superior adhesion and impact resistance, making it a preferred choice for

A size fine filter is a type of filter used to remove small particles or impurities from a fluid or gas.

• Size fine filters are commonly used in industries such as manufacturing, pharmaceuticals, and food processing.

• They are designed to capture particles that are smaller than what can be filtered by regular filters.

• These filters can be made of various materials such as paper, fabric, or synthetic fibers.

• Examples of size ...read more

Direct metalizing is applicable on materials that can conduct electricity.

• Direct metalizing is a process of coating a non-metallic surface with a thin layer of metal.

• The material should be able to conduct electricity for direct metalizing to be applicable.

• Materials like plastic, glass, and ceramics can be direct metalized.

• Direct metalizing is commonly used in the automotive, aerospace, and electronics industries.

The amount of UV energy required for curing depends on the type of material being cured and the intensity of the UV light.

• UV energy required for curing varies depending on the material being cured

• Intensity of the UV light also affects the amount of energy required

• UV energy is typically measured in Joules per square centimeter (J/cm²)

• Examples of materials that require UV curing include adhesives, coatings, and inks

The amount of DFT required as per standard varies depending on the specific industry and project requirements.

• The required amount of DFT (Design for Testability) is determined by industry standards and project specifications.

• Different industries may have different standards for DFT.

• The complexity and size of the project also influence the amount of DFT required.

• DFT techniques include scan chains, built-in self-test (BI...read more

Die casting and machining defects are common in manufacturing processes.

• Die casting defects include porosity, shrinkage, cold shuts, and flash.

• Machining defects include burrs, chatter marks, and tool marks.

• Die casting defects can be caused by improper temperature, pressure, or metal flow.

• Machining defects can be caused by dull tools, improper speeds and feeds, or poor fixturing.

• Defects can lead to part failure, reduced

Filling and high speed ratio formula is used to calculate the filling time of a container with a specific volume of liquid at a given flow rate.

• Filling and high speed ratio formula is V/Q

• V is the volume of the container and Q is the flow rate of the liquid

• The formula is used to determine the time it takes to fill a container with a specific volume of liquid at a given flow rate

• The higher the flow rate, the faster the c

Carbide formation after carburizing can lead to brittleness and reduced strength. Proper heat treatment and tempering can help prevent this issue.

• Perform proper heat treatment and tempering to prevent carbide formation

• Adjust carburizing parameters to avoid excessive carbon diffusion

• Use a different carburizing method, such as gas carburizing instead of pack carburizing

• Consider using a different material with better resi...read more

Reference air is a gas used as a reference point for measuring gas concentrations, while purged air is used to remove contaminants from a system.

• Reference air is typically a gas with a known and stable concentration of a particular substance, used as a baseline for comparison with other gases.

• Purged air is used to remove contaminants from a system or environment, such as in a laboratory or industrial setting.

• Purged air...read more

Carbide, Ferrite and RA are different types of materials used in engineering.

• Carbide is a compound of carbon and a metal, commonly used in cutting tools.

• Ferrite is a magnetic iron compound, used in electrical components.

• RA stands for 'roughness average' and is a measure of surface roughness.

• Carbide and Ferrite are materials, while RA is a measurement.

• Each material has unique properties and uses in engineering applicati

Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint.

• Brazing uses a filler metal with a lower melting point than the base metals being joined.

• The filler metal is heated to its melting point and then flows into the joint by capillary action.

• Brazing is commonly used in HVAC, automotive, and aerospace industries.

• Brazing can be done wit...read more
