NPC DIGIT

Thanks to the continuous technological updating, the hot presses of the NPC series remain a point of reference in their market segment, confirmed by the production of hundreds of pieces per year. PRESS STRUCTURE • Structure entirely made of welded and tool machined beams. HYDRAULIC SYSTEM • The rams are thickness chromed to grant a perfect flowing and a higher working life. • All the cylinders are bolted to the structure, so to be easily removed in case of servicing. • Hawe highly reliable hydraulic power unit fitted with a double stage pump, first stage at low pressure and high delivery to move up the platen, second stage at high pressure and low delivery to get the working pressure set by the operator on the keyboard. • Hydraulic power unit motor plunged in oil bath to get a better cooling and to reduce noise, and further more to avoid any possible damages caused by accidental shocks. ELECTRIC SYSTEM • General switch board from where the operator can set and use all the functions of the press. As a standard equipment all presses are supplied with the automatic pressure recovery device. This accessory allows to keep the same given pressure, even in case the panel, under the platen thrust, shall lower its thickness. • The switch board is mounted on a hinged door (with a 180° opening) so all the servicing operations can be easily carried out. • On the Siemens touchscreen display the operator can set and/or adjust all press functions, particularly: - working pressure (kg/cm2) - working temperature (for presses with electric boiler) - timer to adjust the pressing time - automatic switching On of the heating unit (for presses with electric boiler); possibility to set all days of the week - Automatic pistons shut off according to the dimension of the workpieces setup by the operator. The exclusion is standard on all presses with 8/10 pistons, while it is an option on all presses with 6 pistons) - possibility to use 50% capacity of the boiler (for boiler over 20 kW) • Automatic calculation of the pressure in bar according to the specific pressure in kg/cm2 which must be used for the panels to be worked. MECHANICAL ELEMENTS • All the NPC Presses are fitted with a crossed rack system so composed: 2 rack groups for the platen depth and 2 groups for the length all connected between them by torsion shafts so to grant a perfect platen movement. • 4 lateral guides, positioned on the 4 inner faces of the press legs. This is a further guarantee of a perfect platen movement during either its opening or closing. • The press platen flatness is guaranteed by the precision with which the beams are processed. Indeed both the platens are made with beams welded between them and after mechanically milled. SAFETY DEVICES - Emergency perimeter rope (outside the press structure) - Protection of the racks with cover casings - Lower mobile platen locking device. With the press closed, a support spacer is lowered to prevent the platen movement during maintenance - Two-hand locking control device by means of a contemporaneity control unit - Protection of heating pipes and boiler with net casing. (only for presses with heating system supplied by us) - Emergency push button
