Casting Exhaust Systems

HY company is an excellent supplier of exhaust systems in the world.The exhaust manifold is a critical part of a boat or vehicle's exhaust system, designed to cool the engine and expel explosive gases leaving the engine. Due to the complex structure of the exhaust manifold, it is usually designed and manufactured using a casting process. Considering that exhaust manifolds need to be corrosion-resistant, common materials on the market are aluminum and stainless steel. Cast aluminum exhaust manifolds are becoming increasingly popular and are gradually replacing cast stainless steel exhaust manifolds.

We have casting exhaust system and CNC equipment, as well as lost wax casting production lines to meet the needs of the growing precision investment casting business. In addition, we also have advanced physical and chemical analysis and testing instruments such as spectrometers, metallographic microscopes, tensile testers, and impact testers, as well as two-dimensional projectors, X-rays, ultrasonics, magnets to maintain good internal indications, and three-dimensional coordinate measuring machines Ensure dimensional accuracy.

Quality control begins the moment precision investment casting raw materials arrive at the foundry and continues through every stage of the investment casting process. We have passed the ISO9001:2015 certification of SGS and the PED/AD2015 certification of TUV.

We have developed and manufactured more than 3,300 precision casting exhaust systems, which are widely used in auto parts, construction hardware, marine hardware, pump valves, mechanical parts and other industries. A large part of our investment castings are exported to Europe, the United States, Canada, Israel, and India.
