bronze heat exchanger parts

With the advanced production equipments and informationalized management, we produce OEM Bronze Heat Exchanger Parts strictly based on industrial standards and technique. The custom heat exchanger parts are designed to remove thermal energy from the exhaust gas of natural gas, compressed air, hydraulic oil and transfer it to the water circuit. The extracted heat can be used for space heating, domestic hot water and any industrial process that requires hot water.

Hengchang use sand casting process to produce bronze parts. Sand casting uses resin-bonded sand to construct a mold that the bronze will be cast into. When the mold is cured and the pattern is removed, you can flow molten bronze into the hollow area. Once it cools, the result is a single cast metal object.

Casting Process

1)Make the pattern

2)Make the sandbox

3)Push the pattern into the sand and clay mixture

4)Remove the brass from the furnace

5)Pour the molten brass into the mold 

6)Wait for the brass to cool

7)Cold bathe the mold

8)Remove the mold from the sand using heat-safe gloves

Bronze & bronze alloy casting:

- weight: 0.5-20kg
