Benefits of Lamination of wood
Less prone to natural faults
Increase strength as adhesive is generally stronger than timber
Uses less material/wood
Why Use PVA for lamination
Dries Clear
Does not distract from aesthetic appeal
Water resistant
Suitable outdoors/in wet conditions
Non toxic - safe to use and more environmentally friendly

Why oak for board game
Tough to withstand impacts Strong to resist breaking or splitting Hard so won’t scratch or dent Dense so reduce splintering and smooth surface Heavy so won’t move around in use Durable so will last a long time.
Material for rotational moulding
HDPE
PP
PVC
Why rotational moulding over injection moulding
Hollow, reducing weight
Less material reducing cost
No sprews so minimal waste of material
Cheap mould that is quick to produce
One component not two parts
Less processes so saving costs
No welding marks, increasing aesthetic appeal
Stronger component as no weak points.
Why two components not one
Less wastage of material
Less discarded, less wasted if component is defective
Two parts can be made simultaneously
Anodising not painting
Durable will not peel or chip
More scratch resistant adds a hard layer to the surface
Negligible thickness so holes do not get clogged
Heat resistant so can be used in situation where paint would blister
Less skill to apply, no risk of spillage.
Why ABS
Colours for kids
Doesn’t need coloured finish to be applied
Increasing user engagement and imagination
Very mouldable
Suitable for injection moulding enamelling fast production.
Meeting large demand
Hardness
Scratch resistant
Less build up of bacteria
