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
