This series of PRAGMA machines is the top of range for the production of safety and work footwear, walking shoes and comfort shoes. High-performance machines that are extremely reliable and flexible but also extremely simple to use.

The modular design of the mechanical, electronic, pneumatic and hydraulic systems means that Pragma machines achieve the best results in directly injecting onto upper products in single and dual-density PU and combined TPU+PU.

The layout of each machine and the rational organisation of components make machine access and operations very simple.

The machine is available in two versions:

• PRAGMA PU

single and dual-density polyurethane with totally electric-pneumatic functions.

• PRAGMA COMBI

TPU+PU, with hydraulic system that provides a clamping force of 15 tons on the bottom and excellent controls of the TPU injection unit.

Advantages： 

The modern electronic hardware and software system, together with precise and sturdy mechanics, guarantee reliability and more simple maintenance.

Production flexibility – thanks to a more capacious mould-holder, both in terms of ring opening stroke, sole plate and last-holder movement, able to house larger moulds other than standard (up to size 52).

High quality – thanks to the high clamping force of the mould-holders and the possibility to better distribute the release agent in the mould.
