Joining processes for papers and boards

Design and technology

In this unit pupils will develop technical principles knowledge with an explicit focus on exam technique.

A ready-made part used across different products to make manufacturing easier is called a {{}}.

Which statement best defines a mechanical fixing?

adhesive works equally well on all materials

Which statement is correct about joining methods and materials?

secure parts by passing through a hole and splaying the ends to hold

u-shaped fasteners driven through materials

removable fasteners that hold materials together by pressure

interlocking design commonly used for easy assembly without tools

method of securing pages or materials, often using wire or thread

Match the mechanical fixing to its correct description:

an instant, clean bond using pressure-sensitive adhesive

liquid glue that dries slowly to form a strong, flexible bond

solid adhesive applied with a twist-up tube

melts solid glue sticks to create a fast-setting bond

sprayed evenly over surfaces for quick, large-area bonding

Match the chemical joining process to its correct description:

physical properties/characteristics relate to how a material looks and feels

working/mechanical properties describe material behaviour when exposed to forces

hardness is a physical property/characteristic

elasticity is a working/mechanical property

Which of the following statements is **incorrect**?

it can maintain its shape under normal conditions without breaking

it can resist environmental changes like temperature and moisture

the cost-effectiveness of building a structure

What does 'structural integrity' refer to in materials and structures?

they are always made from recycled materials

they're easier to transport, store and use in different manufacturing processes

they don't require specialised tools to work with

What is one main benefit of using standard stock forms in manufacturing?

Shaping materials again without changing its basic chemical structure is called {{}}.

Which property would be **most** important when choosing a material for a flexible, stretchable item like a bungee cord?
