About us
Ningbo Pingheng Machinery Co., Ltd. was established in 1999, the company adopts the investment casting process (medium temperature wax), also known as the precision casting process, the main materials are: tin bronze, silicon brass and other copper alloys, stainless steel 304,316 and so on. Different materials can be cast according to different national standards.
At present, we mainly provide high-quality precision casting solutions for electric power, automobile parts, engineering machinery, ships and other industries.
EGR INTAKE CHAMBER - STAINLESS STEEL PRECISION CASTINGS
This is a part used in China's well-known car companies, automobile exhaust system - EGR cooler in the parts, the name is called the outlet chamber.
It is made of stainless steel 304 material, which has the advantages of high temperature resistance, corrosion resistance, etc. It is widely used in the field of precision casting parts for automobiles, food machinery, valve bodies, pumps and other precision casting parts.
Inlet and outlet end caps-Brass precision castings
This is a part used in the sea ship parts, sea fresh water heat exchanger system, the name is called inlet and outlet end cap
ZCuZn16Si4 is a casting copper alloy material with high mechanical properties and good corrosion resistance, good casting performance, high mobility, widely used in pipe fittings working in contact with seawater, as well as pumps, impellers, plugs and castings working in air, fresh water, oil, fuel, as well as working pressure of 4.5MPa and in steam at 250 ℃ or less.
Valve-Silicone Sol Precision Casting Carbon Steel Parts
This is an accessory used in the water treatment system, the name is valve;'
The role of the valve in the water treatment system: the valve is used to control the flow of tap water, regulate water pressure and water quality, as well as to ensure the normal operation of the water supply and drainage system;
Characteristics of carbon steel:
1. easy casting: compared to stainless steel, carbon steel usually has a lower melting point, better melting properties, and liquefied state of good mobility, so it is easy to pour into a complete casting.
2. low cost: compared to stainless steel, for high cost control requirements, but parts with low performance requirements of accessories, carbon steel is the first;
Inlet and outlet chambers-copper precision castings
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
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.
