Steel and Iron Wear Resistant Castings

At the time of our foundry’s modernization, TRIMAN’s philosophy was to equip itself in order to manufacture a wide range of parts that can weigh from 4 kg up to 7 t, without almost any limitations. Our foundry is also ca-pable to make a comprehensive range of alloys such as low alloy and carbon steels but also high alloy ductile iron and high alloy cast irons.

Impact and abrasion resistant steels and irons as well as alloy steels specialists.

A surface of 10.000 m², located in the Vega de Arriba industrial park in Mieres, is divided into 6 units:• A casting and melting shop unit of 28*80 m.• • A shakeout, sand reclamation and a materials area unit of 16*50 m.• A processing, fettling and finishing shop of 22*80 m.• 3 workshop of 16*50 m are used for the storage of materials, flammable goods and finished castings and patterns respectively. We also have a machining workshop.• Offices, laboratories, maintenance, pattern work shop, etc… of 750 m².

PRESENTATION• Our Research and Development Department, located in Pamplona, uses Autocad® and Pro-En-gineer® softwares. Moreover, our Mieres technical department has at its disposal all the required CAD licences as well as a skilled staff, and can deal with any kind of drawing.

• Even if pattern making is subcontracted, we dispose of qualified personnel and the appropriate facilities, we can perform repairs and maintenance tasks. We can also adapt the patterns if required.

• Laboratory fitted with two Jovin-Ybon spectrometers of 20 channels, sand testing, a Hoytom universal test machine, a Charpy impact tester, Rockwell and Equotip durometers, a metallographicsaw, microscopes, specimens preparation, N.D.T, a muffle furnace, etc…

• In order to prevent any reaction and superficial alterations, all of our parts are moulded withnitrogen free furan resins. Thus, sand is recoveredup to 95%. Moulding installations are split up into 3 groups: AUTOMATIC, SEMI-AUTOMATIC AND MANUAL.
