Mindarika Senior Design Engineer Interview Questions, Process, and Tips

I have worked on designing various plastic parts for consumer electronics, automotive, and household appliances.

• Designed plastic enclosures for electronic devices such as smartphones and laptops

• Developed plastic components for automotive interior and exterior parts

• Created plastic housings for household appliances like vacuum cleaners and kitchen gadgets

Shut off angle is the angle at which a device stops conducting current in a circuit.

• Shut off angle is a term commonly used in power electronics.

• It refers to the angle at which a thyristor or other semiconductor device stops conducting current in a circuit.

• It is important in controlling the flow of current in AC circuits.

• For example, in a phase control circuit, the shut off angle determines when the device stops conduct...read more

2K moulding technology involves using two different materials in a single mould to create a single part.

• 2K moulding technology involves injecting two different materials into a single mould to create a single part

• The materials are typically different colors or have different properties

• I have worked on designing moulds for automotive parts using 2K technology

The process of opening a 3 plate mold involves separating the mold into three plates to release the molded part.

• 1. Release the locking mechanism holding the mold plates together.

• 2. Separate the mold into three plates: A, B, and C.

• 3. Remove the molded part from the cavity in plate B.

• 4. Open plates A and C to release the part.

• 5. Inspect the part for any defects or imperfections.

• 6. Close the mold plates back together for

Clamping force for a part can be calculated using the formula: Clamping Force = Friction Coefficient x Normal Force

• Calculate the normal force acting on the part

• Determine the friction coefficient between the part and the clamping surface

• Multiply the friction coefficient by the normal force to get the clamping force

• Example: Normal force = 1000 N, Friction coefficient = 0.5, Clamping force = 500 N
