C87200 Silicon Bronze Casting Processes
C87200 Silicon Bronze Sand Casting
C87200 Silicon Bronze Sand Casting uses furan resin-bonded sand moulds for versatile production of large and medium-weight components. Component weights from 0.05 to 200+ kg. Tolerances CT7-CT9, surface finish Ra 6.3-12.5 um. Lead times 1-2 weeks from existing patterns.
C87200 Silicon Bronze Centrifugal Casting
C87200 Silicon Bronze Centrifugal Casting produces sound hollow cylindrical components with centrifugal force expelling gas and inclusions. Tolerances CT5-CT6. Suitable for bushings, flanges, and cylindrical fittings in C87200.
C87200 Silicon Bronze Investment Casting
C87200 Silicon Bronze Investment Casting achieves CT4-CT5 tolerances and Ra 1.6-3.2 um surface finish using the lost-wax process. Ideal for complex-geometry C87200 components requiring precision and fine surface quality.
C87200 Silicon Bronze Green Sand Casting
C87200 Silicon Bronze Green Sand Casting uses clay-bonded green sand for rapid, economical production of standard hardware shapes. Tolerances CT8-CT10. Most economical option for high-volume standard C87200 hardware.
C87200 Silicon Bronze Permanent Mold Casting
C87200 Silicon Bronze Permanent Mold Casting uses reusable steel dies for high-volume production with excellent dimensional consistency. Tolerances CT5-CT7. Ideal for 500-50,000 piece production runs in C87200.
