Advanced Liquid Pressure Forming - ALPF

CMT’s ALPF process has revolutionised the manufacture of aluminium matrix composites (AMC)


CMT was established to exploit manufacturing technology originally developed by the UK’s MoD for the production of AMCs. The Company continued the process development and patented the associated casting process technology, known as Advanced Liquid Pressure Forming (ALPF). This unique process enables the production of AMC components in a fast cycle time, suitable for volume production. Initially, CMT focused on the manufacture of continuous fibre-reinforced AMCs (CFR-AMCs) using unidirectional and 2D wound fibre preforms. Subsequently, CMT has been collaborating with C & J Antich & Sons on the infiltration of 3D preforms, and the development of AMC insert technology. More recently, CMT has also expanded its product offering to include particle-reinforced AMCs (PR-AMCs) in response to customer demand.


The advantage of the ALPF process is due to the inherently fast cycle time, which is much quicker than other AMC casting methods, and the fact that component through-put and handling can be significantly increased with the use of multi-cavity shuttled dies, and other automation equipment, such as die sprayers, dosing furnaces and robotic arms for preform loading and casting removal.
