Extrusion, bending, shearing and deep drawing

Rohan and Nora are on a mission to build the lightest and most innovative structures for their engineering project. As they brainstorm materials for their sheet forming operations, they stumble upon aluminium. What makes aluminium the superhero of their project?

• It is super light, like a feather!

• It has fantastic formability, bending to their will!

• It won't break the bank; it's very affordable!

• All of the above, making it the ultimate choice!

After shearing a piece of AISI 1020 Steel for a construction project, our friend Emma was curious about the changes in the material. She wondered, what happened to the hardness of the sheared region? Was it:

• the same

• half the initial hardness

• twice the initial hardness

Imagine Ethan, a passionate artist, is on a quest to create a stunning metal sculpture that twists and turns with intricate designs. To achieve this, he needs to make the metal more bendable. What magical trick can he use to increase the bendability of the metal?

• Heating it and then decreasing its temperature

• Lowering the pressure of the environment.

• Increasing the temperature.

In a metalworking workshop, Hannah and her friends Oliver and Nora are on a mission to create something amazing! Hannah grabs a punch and skillfully forces a flat sheet-metal blank into a die cavity. What metalworking technique is she using to transform this flat sheet into a masterpiece?

• Extrusion

• Deep drawing

• Shearing

• Bending

In a materials science class, Anika is conducting an experiment to determine the properties of different metals. She needs to identify which of these materials has the largest normal anisotropy.

• Zinc alloys

• Stainless Steels

• Titanium alloys

Emma, a bright and curious student, is diving into the fascinating world of metal sheet manufacturing at her plant. She’s on a mission to discover the perfect temperature for the sheet formation process. Can you help her out? Most manufacturing processes involving sheet formation are carried out at:

• 100 Celsius

• 250 Celsius

• 500 Celsius

• Room temperature

During a manufacturing process, Zoe is tasked with overseeing the extrusion of a new plastic material. She notices that the machinery is struggling to push the material through the die. To improve the efficiency of the process, she considers the use of a lubricant. What is the primary purpose of using a lubricant in the extrusion process?

• To increase the temperature

• To reduce friction

• To enhance material strength

• To change the material properties

During a quality control inspection at a manufacturing plant, Mason noticed several issues with the extruded plastic products. He wondered, which of the following is a common defect in extruded products?

• Surface roughness

• Color variation

• Internal voids

• All of the above

In a manufacturing plant, our friend Charlotte is on a mission to shape some shiny metal components! She's got a big decision to make: which method will she choose to force that metal through a die, all while keeping it cool and collected at room temperature? !

• Hot extrusion

• Cold extrusion

• Warm extrusion

• Isothermal extrusion

Hey there, future engineers! Imagine Anika and Elijah are experimenting with different extrusion temperatures in their lab. What do you think happens to the flow of the material when they crank up the heat? Is it:

• It decreases the flow

• It increases the flow

• No effect on the flow
