Conex is a leading Indian foundry, manufacturer and exporter of Bronze permanent mould castings.
Bronze permanent mould casting is a metal casting process that utilizes reusable moulds to create intricate and high-quality Bronze parts, Bronze Fittings and Bronze Components. Unlike sand casting, which uses a new mould for each casting, permanent moulds can be used hundreds or even thousands of times.
The Process:
- Mould Preparation: A permanent mould is typically made from cast iron, steel or graphite, precisely machined to the desired shape.
- Bronze Melting: Bronze, an alloy of copper and tin, is melted in a furnace at high temperatures; the copper-to-tin ratio is varied for the desired properties.
- Pouring: The molten bronze is carefully poured into the preheated permanent mould.
- Solidification: The bronze cools and solidifies within the mould.
- Finishing: The mould is opened, the casting removed, then cleaned, ground and polished to the desired surface finish.
Advantages of Bronze Permanent Mould Casting:
- High quality with excellent surface detail and dimensional accuracy
- Repeatability — consistent production of identical castings
- Durability — moulds can be reused for many castings (cost-effective at high volume)
- Faster production than sand casting
- Suitable for intricate designs and complex shapes
Applications:
- Hotline clamps & Liveline clamps
- Bronze Electrical grade connectors
- Architectural elements (door handles, railings)
- Gears and Bronze Bushings
- Decorative Hardware
- Plumbing Fittings
