Thanks to the renewed stock of injection and compression presses, and to a mixing system, likewise renewed, INTERMARP has at its disposal advanced process technologies and modern production systems that guarantee control in every phase of production and therefore the uniform quality of the end product.

The MOULDING division comprises 22 presses, 15 of which with vertical injection.
The bimixing presses make it possible to produce completely automatically gaskets with an internal diameter of from 75 to 600 mm, while the horizontal presses are equipped with duel brushes for automatic discharge. Most of the injection presses are equipped with plates with cold grooves with a number of nozzles that varies from 4 to 24.
The use of plates with cold grooves makes it possible to significantly reduce the moulding scraps, to balance with greater precision the quantity of compound in the mould impressions, to cut vulcanisation time and, finally, to allow a better processability of the compounds for use with drinking water of the latest generation, notoriously more difficult to inject.

The compression presses, equipped with a vacuum bell to eliminate the porosity of the manufactured article, have plane dimensions of up to 2500x2500 and are used for the moulding of gaskets with an internal diameter of up to 2000 mm and a weight of 40 kg.
To make ready the preformed parts for the next phase of moulding a special extrusion line is utilised, comprising a 120 mm extruder.
The precise definition of the geometry of the preformed parts and the use of the vacuum make it possible to obtain manufactured articles with a low percentage of scrap and discards.

For the production of compounds Intermarp is equiped with a mixing room which comprises:

• A Francis Shaw K5 closed mill with penetrating rotors, weighing 115 kg with a batch capacity of 99 litres connected with a closed-circuit batching and automatic feeding system for carbon blacks and oils.
• Semi-automatic batching system for minor ingredients
• Two open mills down the line from the closed mill
• Cooling line
• Cut and packaging line
• The entire compounding production cycle is managed and controlled via PC, thus making it possible at any time to keep track of the proper production of the compounds.
• In addition, the bar codes used for the identification of the raw materials used permit the complete and certain traceability of every single batch produced.
