Product Disassembly Exercise


50 mins disassembly time for 5 people.

Two different types of screw heads on base plate caused problems during diassembly.
Tabs construction in heating area meant that pieces had to be physically broken in order to fully disassemble - there was no tidy and impermanent way to pull apart.
Electronic components extremely untidy and wrapped around lots of other components. Vast bulk of internal components were joined in this way - heating basket, exterior trim components.


Aluminium - Main Body casting + exterior visual components;
Galvanised/Corrosion Protected Steel Plate - internal plate components;
Polypropylene - Base plate/chassis, some small internal components;
ABS - button assembly + chrome plated aesthetic finish;
Nylon - electronic housing/heat resistant components;
Rubber/Elastomer - Feet;
Mica sheeting - heat insulation/heating element wrapping
Electronic components - wrapped around front and back of toasting compartment, taking up large volume of toaster internals.


Aluminium and Steel - sheet forming, cold working, stamping
Aluminium Main Body - Injection moulded, washed and painted/anodised
Nylon - injection moulded
ABS - Injection moulded + Chrome electroplated
Polypropylene - Injection moulded, unfinished


Tabs - sheet metal component joining, aesthetic aluminium
Screws - bosses connect electronics to chassis, chassis to main body,
Heat staking - joining nylon components to internal assemblies; such as button electronics assembly to aluminium sheet component, which was screwed down into bosses on main body.
Adhesive - minimal adhesive use to join button tops to assembly underlays.


Electronic Component Fail - Modular and easily accessible electronic PCB assemblies that can be removed and replaced easily in one operation.

Minimise sheer component numbers

Aluminium main body and parts are easily recycled in theory but main body cast is virgin aluminium.
