DIMENSIONAL CHARACTERISTICS

Wall thickness from 0.6 mm to 20 mm
Dimensional precision net-shape or near net-shape :

> tight tolerances

> excellent dimensional repeatability

> flatness

• Linear tolerances :

L ± 0.025 mm up to one inch of dimension (L = 25.400 mm)
L ± 0.1% above one inch

Example : 20 mm ± 0.025 mm
                 76 mm ± 0.076 mm

Across parting line and moving die components : linear tolerance plus an allowance of an additional :
> + 0.051 mm for a projected area of 64.5 cm2
> + 0.254 mm for a projected area of 645.2 cm2

• Flatness tolerances :

L ± 0.076 mm for up to L = 76.2 mm
+ 0.025 mm for each additional 25.4 mm ( or +0.1% of additional length)
(the largest dimension of the flat surface should be used)

Example : 20 mm ± 0.076 mm
                 100 mm ± 0.076 + (100-76.2)*0.1/100 = 100 mm ± 0.1 m

• Physical characteristics :

Lightness : density of 1.82 (2/3 of aluminium and 1/4 of steel)
High thermal conductivity
Heat resistance
No creep at room temperature
Electrical conductivity
Small porosity: as low as 1%
Good surface quality
Excellent damping properties
Electromagnetic interference EMI and radio frequency interference RFI shielding

MECHANICAL CHARACTERISTICS

• Stiffntess and ultimate tensile strength as compared with other materials :

> AZ91D and AM60D : typical magnesium grades used in Thixomolding®

> AISI 1000 : Carbon steel

> AA201.0-T6 and 380 Al: die-cast aluminium grades

> IXEF and Zytel HTN : polyamides reinforced with 30% glass fibres

> ABS and nylon PA6 reinforced with 30% glass fibres
