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 end cover.

Tin bronze, which uses ZCuSn12 as its raw material, is a non-ferrous metal alloy with the least amount of casting shrinkage, making it ideal for castings with intricate designs and distinct contours. Because tin bronze resists corrosion in steam, freshwater, the atmosphere, and seawater, it finds extensive application in steam boilers and parts of seagoing ships.

Product Features & Challenges

  • 1

    Since silicone sol investment casting is an area that produces huge products with sealing requirements, there are strict control requirements for the casting process.

  • 2

    Copper has a lower melting point than steel when cast, and it liquefies at a relatively decent level of fluidity. However, this can easily result in uneven flow of the liquid metal in the mold.

  • 3

    Oxidation issues are easily caused by copper during the casting process.

The low qualification rate of copper precision casting can be attributed to the aforementioned traits.

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

This product has been in mass production since 2012, and has been in stable supply for 12 years, which has given our company a lot of experience in the field of copper casting;

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