Modular vulcanizer made in steel composed by sections of 260 mm length of platen. Available for several belt widths, from 650mm up to 2400mm. The total length of the vulcanization area is assembled by grouping the required units. Each one is independent and includes the hydraulic pressure system, heating system and cooling system. Composed by 2 parts, top and bottom, both include the heating platens that hold the heating elements and the temperature probes. The air cooling system is located in the top part. Completely automatic process programmed from the control unit (heating, dwell time and cooling). The sections are joined horizontally and vertically, allowing the assembly of the press over uneven surfaces.


Control box for up to 4 sections. Easy programming. Automatic control of the whole splicing process, once the melting temperature, the dwell time and the cooling temperature have been set. Incorporates one thermometer and one ammeter per section. The ammeter allows the identification of possible problems in the electrical system of the vulcanizer, besides a voltmeter for input voltage reading that allows to detect any problem in the power supply. Automatic end-of-cycle buzzer.

Pressure System

Adjustable and applied by means of hydraulic cylinders connected in series, built in the lower beam and from high quality materials. Two versions available: 7 bar (100PSI) or 14 bar (200PSI). The weights and heights of the sections may vary depending on this. Pressure may be supplied from: manual hydraulic unit or electrohydraulic unit.

Heating System

Fast heating of the platens by means of stainless steel 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

The cooling system consists of 2 high-performance fans placed on the fiber glass of the top part of each section. Air favours a rapid temperature reduction of the belt and reduces waiting time for a new use of the press. They activate automatically or manually from the control unit process.


Light safety bolts that allow a perfect assembly of the sections. Steel made. Easily adjustable to different belt thicknesses. Designed with safety factor 2 (capable of withstanding twice the maximum load pressure of the beam).
