PXE Mould-holding

Mould holding presses or commonly called “book” or “shell” opening presses, are used for moulding integral polyurethane, a flexible but at the same time compact and wear-resistant material, with a smooth or embossed appearance depending on of the customer’s request, which is used as a component for the automotive sector, for furnishings, for sporting goods and in PXE PRESSA PORTA STAMPI • MOULD HOLDING PRESS TYPE • PRESSE PORTE MOULES • PRENSA PORTA MOLDES 11 all those applications that require the combination of softness and mechanical strength.
The same machines can also be used for the semi-rigid polyurethane that is moulded with R.I.M. (Reaction Injection Moulding) technology and being a semi-rigid material with high mechanical resistance, it is ideal for the realization of industrial components and bumpers, panels, body parts for the automotive and transport sectors.
Since long time, Ormamacchine has decided to implement and enrich its production of presses dedicated to polyurethane, adding to the discontinuous plants for the production of PUF panels, specific types of machines such as the “MOULD HOLDING” series of presses like the “PXE 13/08”. The main features of this press are: lower movable platen (upstroke design) (clearance between platens 800 mm), with the possibility of the upper platen “book” opening with a maximum angle of 80 ° and the possibility of an 45° intermediate opening. This solution is used to facilitate operators in the upper semi-mould replacing operations. The press is accessible from three sides.
The structure of the upper fixed platen and the lower movable platen is in HEB beams welded and spaced to allow the fixing of the moulds and the foaming process both on the 3 free sides of the moulds, and from above. Complete the versatility of the machine, the possibility of inclination, both on the short side and on the long side to facilitate the exhaust of the gases during the expansion phase of the PU. The inclination adjustment is managed by a manually adjustable limit switch Finally, we want to point out that, in the “green” perspective pursued by Ormamacchine in the recent years, the current chemical and process compositions of polyurethane products do not use aggressive solvents and do not use CFC11 or HCFC, giving rise to an inert product. The use of this material as thermal insulation contributes to energy savings and therefore to a positive impact on the environment.
