Aluminium made press. Available for several belt widths: from 300mm up to 4600mm (superior dimensions under request). Incorporates pneumatic pressure system, heating system, water cooling system and clamping bar. The press is divided into 2 parts (top and bottom). Each integrates aluminium platens with heating elements, cooling pipes and temperature probes. Length of platen: 150mm (up to 2200mm) or 200mm. Completely automatic process programmed from the control unit (pressure, heating, dwell time and cooling).


Easy to program control unit. Automatic control of the whole splicing process once the melting temperature of both platens, the dwell time, the cooling temperature and the pressure have been set. The control box features an Automatic Temperature Regulation System (ATRS), that monitors automatically the differences of temperature between the heating platens during heating and dwell time. By doing so, differences of more than 2ºC are avoided. Includes voltmeter for input voltage reading that allows to detect any problem in the power supply. Includes also a pressure regulator, manometer and pneumatic valve with quick inflation and deflation. Automatic end-of-cycle buzzer.

Pressure system

The pressure is supplied equally by means of a wide section airbag inside each frame. Depending on the maximum pressure to reach, there are 2 models: 3 bar or 5 bar. The weights and heights of the sections may vary depending on this.

Heating system

Fast heating of the platens by means of heating elements. Each one is made with an asymmetrical winding to supply an even heat distribution all along the belt. The elements get warmer on the ends to compensate the loss of temperature and avoid heat concentration in the middle. Temperature programable up to 200º C / 392º F.

Cooling system

Water cooling system composed by a closed stainless steel circuit, that help circulate water all along the platens propelled by a water pump. Water favours a rapid temperature reduction of the belt and reduces waiting time for a new use of the press. Cooling system activates automatically after dwell time finishes.

Clamping system

Fixing the belt by means of automatic clamping bars. Two intermediate plates of galvanized steel (1,5 mm thickness) are also supplied for the protection of the heating plates. These plates also dissipate the heat and avoid marks on the splice area.


Easily adjustable to different belt thicknesses. Steel made with safety factor 2 (capable of withstanding twice the maximum load pressure of the press).
