High-precision models for lost-wax casting • Model measurements up to 1.000 x 600 x 500 mm • Suitable for autoclaves, even for thin-walled shells • Same handling as for conventional wax parts • Can be burnt out in normal kiln with low emission • Tool-less and hence more cost-effective process • Single items and small series can be produced within a few days formation • Does not expand during burn-out process, hence no shell cracking (whether gypsum or ceramics) • High degree of accuracy: ±0.4% (min. +/- 100 µm) • Residual ash contents <0.02% for polypor binder type C • Wax infiltration creates closed smooth surface • All alloys can be used with lost-wax casting process Investment casting process 3.
