Note 1 - HB=Brinell, RW=Rockwell. Higher numbers indicate increased hardness levels. Note 2 - Values in BTU/[(Ft.² Hr.°F)/Ft.] at 68°F - higher numbers=greater thermal conductivity. Note 3 - *=Alternatives to QC7 with very similar characteristics may sometimes be used. |
| These specifications provide the following benefits & allow us to make production quality aluminium alloy mould tools & mouldings for you in less time & lower cost than our competitors |
| 5 reasons aluminium alloy mould tools are better than steel mould tools |
| ✓ Easier to machine/polish - fast delivery lower cost & simpler modifications |
| ✓ 4 x thermal conductivity of steel - better tool heat dissipation & thus, faster cycle times |
| ✓ Closer to tool temp. ejection - less stress, distortion, warpage & post mould shrinkage |
| ✓ Excellent consistency & experience of 600+ mould tools - we'll guarantee your tool life |
| ✓ 1/3 weight of steel - reduced machine energy use & staff fatigue loading tools/inserts |
