Mechanical stoppers are used to limit the movement of a mechanical component or system.
Mechanical stoppers are commonly used in machinery to prevent overtravel or to establish a specific position.
They can be adjustable or fixed depending on the application.
Examples include limit switches, physical barriers, and adjustable bolts.
Proper maintenance and inspection of mechanical stoppers are crucial to ensure safe and effi
PLC stands for Programmable Logic Controller, used in industrial automation to control machinery and processes.
PLCs are used to automate processes in industries such as manufacturing, automotive, and food processing.
They can be programmed to control various devices such as motors, sensors, and valves.
PLCs help improve efficiency, reduce human error, and increase productivity in industrial settings.
Examples of PLC brand...
SMPS stands for Switched Mode Power Supply, which is used to convert electrical power efficiently.
SMPS is a type of power supply that uses a switching regulator to convert electrical power efficiently.
It is commonly used in electronic devices such as computers, televisions, and LED lights.
SMPS is preferred over linear power supplies due to its higher efficiency and smaller size.
It operates by rapidly switching the inpu...

Injection Moulding Working Process.
Injection moulding is a manufacturing process used to produce parts by injecting molten material into a mould.
Injection moulding is a widely used method for manufacturing plastic parts.
It involves injecting molten material, typically plastic, into a mould cavity.
The molten material solidifies inside the mould, taking its shape.
The mould is then opened, and the finished part is ejected.
Injection moulding allows for high...

Mold temperature controller regulates the temperature of the mold during the injection molding process.
The controller uses a heating and cooling system to adjust the temperature of the mold.
It helps in maintaining consistent and optimal temperature for the molding process.
Temperature sensors are used to monitor and control the temperature.
The controller can be set to specific temperature ranges based on the material be...
Injection molding process involves melting plastic pellets and injecting them into a mold cavity to create a desired shape.
Plastic pellets are heated and melted in a barrel
The molten plastic is then injected into a mold cavity
The plastic is allowed to cool and solidify in the mold
The mold is opened and the final product is ejected
There are two types of sequence gates available: AND gate and OR gate.
AND gate requires all input signals to be true in order to produce a true output signal.
OR gate requires at least one input signal to be true in order to produce a true output signal.
I applied via Walk-in and was interviewed before Oct 2022. There were 3 interview rounds.
Core and cavity are the two main components of a mold used in injection molding processes.
Core is the part of the mold that creates the internal features of the final product
Cavity is the part of the mold that creates the external features of the final product
They work together to form the shape of the product being manufactured
Examples: In a plastic cup mold, the core would create the hollow interior while the cavity
The material commonly used for core and cavity in tool room engineering is typically tool steel.
Tool steel is a popular choice for core and cavity material due to its high hardness and wear resistance.
Common types of tool steel used include P20, H13, and S7.
Tool steel can be heat treated to achieve desired hardness and toughness properties.
Other materials such as aluminum or pre-hardened steel may also be used dependin
