Through our strict manufacturing processes, we guarantee quality

  • Mixing arm: equipped with a 40t/h IMF mixer.
    Automatic adjustment of programs, flow rates, temperatures and hardening times.
  • Carousel nº1: deals with a 10 or a 20 semi-moulds
    IMF installation fitted with: patterns positioning
    stations, “fast loop“ compaction and moulding,
    turner-stripper, painting and drying station, automatic
    moulds handler, distribution to castingwaiting
    lines, shakeout, casting, waiting-stripping.

  • Painting facilities, flow coating installation with auxiliary machinery for specials paints.



Casting is done through a semi-gantry crane with ladle
automatic positioning.

  • 3 Inductotherm medium frequency electric furnaces with a
    capacity of 2.5 t and 2 t/h respectively, with a basic liner and fitted with a vacuum dust collector.
  • 4 bottom-pour ladles of 5 t.
  • 8 bottom-pour ladles of 2.5 t.
  • 8 Cucharas para 2.5 t.
  • Melting is assisted by 2 travelling cranes of 8 t.
  • Ladles heating through an oxy-gas station.
  • Stationary and hanging weighing machines, pyrometers,etc…


This installation has been designed and made by TRIMAN and
enables to reclaim up to 95% of the silica sand we do use.
Made up of:

  • Shakeout double grid on hopper, magnetic separation of
    metals, attrition unit that processes sand for an hour in order to dispose of all resins rest.
  • Classification through screening and storage in 3 silos of 60 t
    in order to keep the temperature stable.
  • Vacuum dust collector for dust from shakeout and classification.
  • Pneumatic conveying to intermediate silo, classification on
    fluid bed and separation of oxides, slag and other magnetic
    particles. Then new vacuum cleaning.
  • Pneumatic conveying to consumption silo.
  • Cleaning by suspended load shotblasting machine.
