PU INJECTION MACHINE/ ROTARY TABLES
DESMA has been developing and producing rotary tables in various sizes for the production of technical articles since 1960. There are two main types of rotary table.
Rotary tables for manufacture of poured articles
DESMA offers rotary tables for the production of poured articles. Pouring units, either manually or robot controlled, pass over the open mould and pour in the correct amount of material. The mould is then closed and locked. The material, usually foamed polyurethane, expands in the closed mould until final hardness has been reached. De-moulding follows later.
Rotary tables for the manufacture of injected articles
Such rotary tables are characterised by the injecting of material into the closed mould. Injection takes place using low pressure units in front of the rotary table. Moulds on these rotary tables, which may have 12, 18, 24 or 30 stations, open horizontally.
