What is Foaming defects and reason for occurence.

Q1. What is Foaming process ?
Ans. 
Foaming process is a manufacturing technique used to create foam-like structures by introducing gas bubbles into a liquid or solid material.
• Foaming process involves the creation of gas bubbles in a material.

• The gas bubbles can be introduced through mechanical agitation, chemical reactions, or the use of foaming agents.

• Foaming can be done with various materials such as plastics, metals, ceramics, and even food products.

Q3. What is the RTD and thermocouple
Ans. 
RTD stands for Resistance Temperature Detector and Thermocouple is a temperature sensor made of two different metals.
• RTD measures temperature by detecting changes in electrical resistance of a metal wire as temperature changes.

• Thermocouple generates a voltage proportional to the temperature difference between its two junctions.

• RTD is more accurate and stable than thermocouple.

• Thermocouple is cheaper and can measure a w...read more

Q4. What is the no and nc
Ans. 
NO and NC are abbreviations used in electrical circuits to describe the state of a switch or relay.
• NO stands for Normally Open, which means the switch or relay is open (off) in its normal state.

• NC stands for Normally Closed, which means the switch or relay is closed (on) in its normal state.

• NO and NC are commonly used in control circuits to indicate the position of a switch or the state of a relay.

• For example, in a lig...read more

Q6. What is the transformer
Ans. 
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.

• When an AC voltage is applied to the primary coil, it creates a magne...read more
