Drawing

For this type of machining, our R&D workshops have developed a line of products of which we are particularly proud.

These formulations, derived from renewable sources in line with the most stringent regulations governing environmental safety in the workplace, can drastically reduce friction forces and eliminate greater amounts of heat during the work cycle, so as to allow a reduction in the axial force applied to the metal deformation. Consequently, it is possible to obtain energy savings, reduction of waste and extend the average life of moulds.

The process of drawing is affected by radial forces of tension, to tangential stresses of compression and the force to be exerted during the process of drawing depends on various factors: the type of material, lubrication, the shape of the mould components, on the pressure of the hold-down clamp etc.

In this complicated equation, LMI is trying, by analysing every aspect in an integrated manner, to simplify the factors, by reducing the drawing force through an eco-friendly, applied chemical technology, derived from renewable, biodegradable sources, which safeguard the health of the operators, to look for formulations that are free of PAHs (petroleum derivatives that are potentially carcinogenic to humans) PCB (polychlorinated biphenyl), and PCTS (polychlorinated terphenyls) and heavy hydrocarbons (C 10- C40)
