As a leading factory among China suppliers, we ensure that our products meet stringent quality standards. Our rigorous testing requirements include an air tightness test, where the part must withstand 0.5MPa of compressed air for one minute without any leakage, Choose our marine vessel component for dependable performance and superior quality from a trusted supplier in China

Product Description

This is a part used in sea vessel components, sea and fresh water heat exchanger system, the name is end cap.

Adopting ZCuSn12 as the material, tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage, which can be used to produce castings with complex shapes and clear contours; tin bronze is very corrosion-resistant in the atmosphere, seawater, freshwater and steam, so it is widely used in steam boilers and seagoing ship parts.

Product Features

1

In the field of silicone sol investment casting, which is considered a large product, and the product has the sealing requirements, so for the casting process control requirements are high.

2

Compared with the casting of steel, copper melting point is relatively low, liquefied when the mobility is relatively good, but also easy to lead to liquid metal in the mold uneven flow.

3

Copper in the casting process is easy to produce oxidation problems.

The above characteristics lead to the low qualification rate of copper precision casting.

Frequently Asked Questions

What is the primary application of this copper end cap?
This end cap is designed specifically for components used in marine environments, specifically for sea vessel components and sea and fresh water heat exchanger systems.
Why is ZCuSn12 tin bronze selected as the casting material?
ZCuSn12 (tin bronze) is chosen because it has the smallest casting shrinkage, making it ideal for producing castings with complex shapes and clear contours. Additionally, it offers exceptional corrosion resistance in atmosphere, seawater, freshwater, and steam.
What makes the casting process of this product challenging?
The challenges stem from its large size in silicone sol investment casting and strict sealing requirements. Furthermore, copper's low melting point leads to high liquidity and potential uneven flow in the mold, and it is highly prone to oxidation during casting.
How does your company address the low qualification rate in copper precision casting?
Through our rich technical experience established since 2012, a dedicated technical development team, and rigorous process controls, we successfully manage the complexities of copper casting to maintain a smooth and stable supply.
Do you provide machining services for these cast components?
Yes, we provide fully integrated services from the initial precision casting stage to final machining, ensuring the final shaped parts meet all dimensional and operational specifications.
