Bronze Shell Molding Parts

Bronze Shell Molding Parts

We cast various Bronze shell moulded parts (shell casting of Bronze) in our foundry as it is a cost-effective way of making intricate Bronze castings. Most of these parts made at our shell moulding foundry need minimum machining and are highly cost-efficient.

The main difference between Sand Casting and Shell Mould Casting is the mould. In Shell Mould Casting, the mould is a thin walled shell created by applying sand raisin mixture around the pattern. The pattern is a metal piece in the shape of the part to be cast. The pattern is reused to form multiple Shell Moulds.

The Advantages of Bronze Shell Moulding Parts includes :

  • The Shell Moulding Casting enables the manufacturing of complex parts with dimensional tolerance of approximately 0.2 mm
  • The surface finish is usually good and consistent resulting in lower machining requirement and cost
  • Tooling costs are comparatively low and shorter lead times are required
  • Consistent quality of Bronze shell moulding once a tool is made and finalized

Some of the Bronze Shell Moulding Parts manufactured by us includes :

  • Hydraulic equipment Parts
  • Electrical connectors
  • Grounding clamps, Ground rod clamps
  • Bronze pipe clamps
  • Bronze transformer eye bolts
  • Bronze terminals for electrical transformers
  • Bronze gear parts
  • Bronze bearing parts and components
  • Marine fittings in bronze like thru hull and strainers for boats
  • Bronze bushings

Grades of Bronze used for Shell Moulding are :
