Abstract (en)
[origin: EP0819487A1] The apparatus for production of die-castings includes a die (12) and a suction system for controlled evacuation of the die cavity. The suction system consists of a vacuum tank (18) and a suction line (20) with a valve (22) connecting the vacuum tank to the die cavity. The suction line incorporates another valve (24) arranged in series with the valve (22) so that a reference space (26) is formed between the valves (22, 24). Also claimed (below) is a method for production of die-castings.
