Product description

This is a part used in the sea vessel components, sea and fresh water heat exchanger system, the name is inlet and outlet water chamber.

ZCuSn12 is the raw material used to make tin bronze, a non-ferrous metal alloy that has the least degree of shrinkage during casting, which makes it perfect for castings with complex patterns and sharp features. Tin bronze is widely used in steam boilers and on sections of seagoing ships due to its resistance to corrosion in steam, freshwater, the environment, and seawater.

Product features

  • 1
    Due to the sealing requirements of this product, there are strict control requirements for the casting process.
  • 2
    When cast, copper melts at a lower melting point than steel and liquefies with a rather good degree of fluidity. But doing so could easily cause the liquid metal in the mold to flow unevenly.
  • 3
    Copper during the casting process might quickly lead to oxidation problems.

These characteristics explain the low certification rate of copper precision casting.

From the receipt of the project, our technical team worked night and day to overcome the difficulties, and through continuous optimisation of the pouring system, control of pouring temperature and flow rate, the project was finally developed successfully and formed into mass production.

Our company has a great deal of experience in the field of copper casting because this product has been in steady supply for 11 years and has been in mass production since 2013;

Our company has a strong technical development team, with the development of precision casting of various shaped parts in the field of ability, and to provide integrated services from casting to machining, striving for excellence, to provide customers with efficient, high-quality products and services has always been our adhering to the concept.

Frequently Asked Questions

Q: What is the primary application of this water chamber component?
This component is an inlet and outlet water chamber used in sea vessel components, specifically designed for sea and fresh water heat exchanger systems.
Q: What material is used for the water chamber, and why?
ZCuSn12 (tin bronze) is used. It is a non-ferrous metal alloy that offers minimal shrinkage during casting, making it ideal for complex patterns and sharp features. It also provides excellent corrosion resistance in steam, freshwater, seawater, and marine environments.
Q: What makes copper precision casting challenging?
Copper melts at a lower temperature than steel and has high fluidity, which can cause uneven flow inside the mold. Additionally, copper is highly prone to oxidation during the casting process, which typically leads to low certification rates.
Q: How did your technical team achieve successful mass production?
Our technical team optimized the pouring system and strictly controlled both the pouring temperature and the flow rate to overcome copper casting difficulties, successfully moving the project into mass production.
Q: How long has this product been in production?
We have a wealth of experience with this product, having kept it in steady supply for 11 years and in mass production since 2013.
Q: What capabilities does your company offer for copper casting?
We possess a strong technical development team capable of precision casting various shaped parts, providing fully integrated services from initial casting to final machining.
