COMPARISON OF MOULD TOOL MATERIALS

MOULD TOOL MATERIAL	DENSITY G/CM³	HARDNESS (SEE NOTE 1)	THERMAL CONDUCTIVITY (SEE NOTE 2)	YIELD STRENGTH KSI
QC7 ALUMINIUM ALLOY *	2.833	167HB	91	74-79
STANDARD ALUMINIUM	2.722	95HB	96	40-42
P20 TOOL STEEL	7.888	28-37RW	20	130-135
H13 QUALITY TOOL STEEL	7.777	52-54RW	14.4	228

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 and ultimately, enable us to make production quality injection mould tools & mouldings for you in less time & at lower cost than our competitors.

5 reasons aluminium alloy mould tools are better than steel mould tools

ü Easier to machine/polish - higher cost savings, shorter deliveries & simpler modifications.

ü  4 x thermal conductivity of steel - better tool heat dissipation & thus, faster cycle times

ü  Closer to tool temp. ejection - less stress, distortion, warpage & post mould shrinkage

ü  Excellent consistency & experience of 200+ mould tools - we'll guarantee your tool life

ü  1/3 weight of steel - reduced machine energy use & staff fatigue loading tools/inserts
