Bronze casting parts are widely used in machinery manufacturing, construction, automobiles, ships and other industrial sectors. At present, the commonly used bronze castings are tin bronze, manganese bronze, aluminum bronze and lead bronze, etc. These bronze castings generally have high mechanical properties, corrosion resistance, wear resistance and so on. We can also add aluminum, iron, nickel, manganese and other elements to the bronze material to improve the corrosion resistance, heat resistance and strength of bronze castings. There are also difficulties in the casting process of bronze, which is mainly reflected in the wide crystallization temperature range of bronze, mushy solidification, poor fluidity, difficulty in feeding, dendritic segregation and scattered shrinkage holes, and it is difficult to obtain a dense Investment Casting Parts. SCZY has a unique way of dealing with these difficulties, which can achieve better results.
In addition to the production of investment castings, SCZY also provides follow-up secondary CNC machining and other follow-up services.
