Abstract

Un articolo avente fori laterali (11), ad esempio un distanziatore (10) per un radiatore per riscaldamento centrale, è costituito da materiale in particelle costipate in uno stampo comprendente una piastra (1) avente una cavità verticale (2), un punzone superiore (7) ed un punzone inferiore (4). Un'asta di anima interna (3) forma un passaggio centrale nel distanziatore (10) ed aste di anima laterali (6) formano i fori laterali (11). La densità del materiale costipato che delimita i fori laterali (11) è maggiore che nel resto dell'articolo.An article having lateral holes (11), for example a spacer (10) for a central heating radiator, consists of material in compacted particles in a mold comprising a plate (1) having a vertical cavity (2), an upper punch (7) and a lower punch (4). An internal core rod (3) forms a central passage in the spacer (10) and lateral core rods (6) form the lateral holes (11). The density of the compacted material that delimits the lateral holes (11) is greater than in the rest of the article.
