  2. Precision investment casting

  3. Precision investment casting • Moulds for investment casting are made from easy melt-able materials like is wax or plastics. • Thanks to high temperature used during forming difficult moulds with small diameters and smooth surfaces can be made. • Moulds are accurate with smooth surface.

  4. Precision investment casting • 1) Manufacturing of forms for moulds. • 2) Manufacturing of wax moulds. • 3) Cluster casting of moulds. • 4a) Manufacturing of shell moulds – soaking • of moulds into casting slip. • 4b) Manufacturing of shell moulds – • powdering of wax moulds with refractory • material • 5) Extraction of wax moulds.

  5. Precision investment casting • 6) Shell firing • 7) Melting and Casting • 8) Ceramic disposal • 9) Parting of moulds from gating system • - cutting • 10) Disposal of gating from moulds • – grinding • 11) Completion work – sand blasting, • grinding, polishing • 12) Monitoring

  6. Precision investment casting • For wax mould manufacturing is used few wax mixtures differentiating according to final use and physical quality. • • Wax for moulds – clean (non filled) • - filled • - emulsified • • Waxes for gating systems • • Re-cultivated waxes • • Special waxes – adhesiv • - soaking • - reparative • - wax cores • - soluble waxes
