Define part areas that demand extra strength
A mould tool can be customised and segmented into different zones, this give you the capability of taking advantage of a higher or lower density in a specific area of the same moulding.
A dual density moulding can offer you:
- Better durability
- Cost savings
- Different properties & qualities where needed
- Enhanced protection and shock absorption in specific areas that could be prone to stress
For this dual density base pack for a heavy boiler 4 small rectangular areas have been moulded in a high density to reduce the damage caused by strapping cutting into the EPS material.
The top and base of the boiler pack are moulded in 25g/l
The 4 high density sections on the corner edges are moulded in 70g/l (highlighted yellow)
You can observe the difference it makes where the strapping is concerned.
