Joining (Common content)
Muhtasari
Very few products are made from a single piece. Almost everything around you is an assembly: parts that have been joined together, sometimes so they can be taken apart again and sometimes so they never will be. Knowing which joining method to use, and whether it should be temporary or permanent, is one of the most practical decisions a designer makes.
This note sorts joining methods into temporary (can be undone without damage) and permanent (cannot be undone without destroying the joint) for each class of material: papers and boards, woods, metals and polymers. You will learn the common methods, when each is the right choice, and how the same job can often be done either way depending on whether the product will ever need servicing, flat-packing or recycling.
Malengo
- show knowledge of temporary and permanent methods for joining the classes of materials listed in section 1.5.
