10+ Interview Questions and Answers

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 depending on the specific requirements of the tool.

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 production volumes and complex part geometries.

• It is used...read more

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 being used.

• Proper temperature control is crucial for achievi...read more

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.

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 would create the outer shape

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

Injection moulding is a manufacturing process where molten material is injected into a mould cavity to create a solid object.

• Molten material is injected into a mould cavity under high pressure

• The material cools and solidifies to form the desired shape

• Commonly used for producing plastic parts in mass production

• Used in various industries such as automotive, medical, and consumer goods

Injection moulding is a manufacturing process used to produce parts by injecting material into a mould.

• Injection moulding involves melting a material and injecting it into a mould cavity

• The material solidifies inside the mould and is then ejected as a finished part

• Common materials used in injection moulding include plastics, metals, and glass

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 efficient operation.

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 input voltage on and off to regulate the output voltage.

• SMPS c...read more
