Injection device for filling ceramic moulds, has mobile assembly that brings perforated disc to outlet for intercepting flow of slip in final phase of filling at high pressure, to limit flow of slip to micro-jets

摘要

The device has a body (1) to be connected with a slip supply (2). The body has an outlet opening that communicates with a mold cavity to pass the slip at a maximum rate at low pressure to the cavity. A mobile assembly brings a perforated disc (5) to the outlet for intercepting the flow of slurry in a final phase of filling at high pressure to limit the flow of slurry to micro-jets generated by the perforations.
