Our vision to consistently invest in the very latest technology has put KMF at the forefront of manufacturing. In order to sustain our drive to increase our competitive advantage, emphasis is made to automate the process where possible.

Using Trumpf CNC punching machines, KMF can offer high accuracy, high speed and competitively priced parts.
KMF's punching facility consists of: Four TruPunch 5000's, a TruMatic 6000 Combination Punch/Laser. Efficiency on all but one TruPunch 5000 has been increased by links to our Flexible Manufacturing Cell (FMC).

Stopa storage towers feed the machines, each tower being capable of storing 90 tonnes of a range of raw sheet steel ready to be processed into the FMC. The automated components within the cell enable a 60% increase in efficiencies compared to a conventional manual punching machine system.
