10+ Shubhada Polymers Products Interview Questions and Answers

A paint thickness gauge can be used to check if painted metal is damaged.

• Use a paint thickness gauge to measure the thickness of the paint on the metal surface

• If the paint thickness is below the recommended level, it may indicate damage to the painted metal

• Look for any inconsistencies or irregularities in the paint thickness readings

Defects such as scratches, dents, rust, and uneven surfaces are checked in the material before and after painting.

• Scratches

• Dents

• Rust

• Uneven surfaces

The stage at which if the work is not done, the line does not run is the production stage.

• The production stage is crucial as it involves the actual manufacturing or assembly of the product.

• If the work is not done at this stage, the product cannot be completed and the production line cannot operate.

• This stage typically includes processes such as machining, fabrication, assembly, and quality control.

• For example, in an automobile manufacturing plant, if the assembly of the engin...read more

Common defects in paint shop quality include orange peel, runs, sags, dry spray, and dirt contamination.

• Orange peel texture on the surface

• Runs and sags in the paint finish

• Dry spray leading to uneven coverage

• Dirt contamination causing imperfections

• Color mismatch or inconsistency

Processes in a paint shop include surface preparation, priming, painting, and curing.

• Surface preparation involves cleaning, sanding, and masking off areas not to be painted.

• Priming is the application of a base coat to improve adhesion and corrosion resistance.

• Painting is the application of the desired color coat using spray guns or other methods.

• Curing involves drying and hardening the paint through heat or chemical processes.

A heat exchanger is a device used to transfer heat between two or more fluids, allowing them to exchange thermal energy without mixing.

• Heat exchangers are commonly used in HVAC systems, refrigeration, power plants, and chemical processing.

• They work by transferring heat from one fluid to another through a solid wall, without the fluids coming into direct contact.

• Examples of heat exchangers include shell and tube, plate, and finned tube heat exchangers.

Hydraulic refers to the use of liquid to transmit power or energy.

• Hydraulic systems use a liquid, typically oil, to transmit power.

• The liquid is pressurized and then used to move components in the system.

• Common examples of hydraulic systems include car brakes and hydraulic lifts.

• Hydraulic systems are often used in heavy machinery and industrial equipment.

Tolerance in production fabrication refers to the allowable deviation from a specified dimension or quality.

• Tolerance is the acceptable range of variation in a dimension or quality of a part or product.

• It ensures that parts fit together properly and function as intended.

• Tolerance can be specified as a plus/minus value or a range of values.

• For example, a part may have a tolerance of +/- 0.005 inches for its length.
