Application:
The FI moulding machines, version B, are based on a low-pressure impulse moulding method of working pressure not exceeding 0,6 MPa. They need approximately the same production area as the FKT jolt-squeeze machines. The FI-B impulse moulding machines with alternate pattern plate are adapted to moulding boxes used in impulse moulding technology (straight walls, increased rigidity). It is also necessary to use top sand frames.
Advantages:
- possibility to make lower and upper mould halves alternately in one working station,
- reduction of noise level below the permissible limits,
- instantaneous noise below the permissible limit of 115 dB,
- noise intensity for 8-hour exposure below 85 dB,
- shortening of machine time of the moulding machine which is connected with increased productivity,
- no jolt-squeeze unit which is the source of noise and vibrations,
- compaction operation of moulding sand by means of a compressed air impulse is only several milliseconds long,
- stable design with only few friction elements contribute to a long life of the moulding machine,
- simplicity of design and very high reliability.
