Steel moulding casting

The steel moulding casting process involves many manufacturing phases.
It begins with the wooden model positioned in the support bracket. This is filled with a mix composed of sand, resin and hardener catalyst. The mix is auto-hardening and fills every corner of the bracket. After obtaining the form of the part to be manufactured, the template is removed and varnished in order to ensure integrity and resistance to molten metal temperature. After casting, 24 to 72 hours are required in order for the part to cool down completely. Next come the phase of knocking out: the cast parts are positioned on the work surface where sand is separated from the part through vibrations; the part then goes through to the finishing phase. Sand is gathered in the recovery plant and recycled by means of mechanical and heat processing, with a recovery rate of around 95%. The next phase is sandblasting to clean the surface of the part and remove any residue. The biscuits and tapping spouts are cut and reused in the casting process. The part is inserted into a special cabin for deburring and it is inspected to check its overall compliance with relevant requirements.
After the cleaning process, the part can be assembled and subjected to heat treatments, or move to the final inspection phase:

  • Chemical analysis
  • Visual and dimensional analysis
  • Liquid penetration analysis
  • PMI (positive material identification)

After steel moulding casting process testing can be performed by external laboratories upon the request of the Client or specific procedures for certification of 2M’s internal processes. These testing may include X-rays, hot or cold mechanical tests and ultrasound.
