The plastic injection moulding industry has long used conventional steel with relatively high carbon levels in the construction of moulding parts, for delivery in a pre-treated state.
For those who understand the specificities of design and injection, the new aluminum alloys obtained from research conducted by the aeronautical industry are now used for mould manufacturing.
Their mechanical properties (hardness, tensile strength and yield strength) allow the production of both prototypes and series of up to 100,000 pieces.
Cost of tooling and parts
The thermal conductivity of the aluminum alloys is 5 times that of steel. Since the parts’ cooling time represents 70-75% of the injection cycle, the productivity of the injection process is improved, particularly for high-speed presses.
Potential for innovation
This conductivity opens up new possibilities in terms of complexity of form, size, thickness, tolerance, flatness, corner finishing, dimensional accuracy and use of inserts.
The use of aluminum tooling for final material injection guarantees the perceived quality of your products.
The perceived quality of your product depends on:
- the piece’s appearance and aesthetics (appearance, colour, lustre, "warmth" of visible surfaces),
- the tactile perception of its surfaces,
- and the right "heft".
Time to market
The machinability of aluminum reduces the time to market.
