Abstract (en)

[origin: WO9408743A1] An article (10) having side holes (11), e.g. a spacer (10) for a central heating radiator, is made of compacted loose particulate material in a die comprising a plate (1) having a vertical cavity (2), a top punch (7) and a bottom punch (4). An inner core rod (3) forms a central passageway (12) in the spacer (10) and side core rods (6) form the side holes (11). The density of the compacted material defining the side holes (11) is higher than in the remainder of the article (Figure 2).
