Investment castings

Investment castings

Investment castings have the advantages of high dimensional accuracy and the ability to cast complex thin-walled parts, and play an increasingly important role in the aerospace field. With the increasing complexity and integration of the structure and size of castings in the aerospace field, higher requirements are put forward compared to investment precision manufacturing. According to actual needs, it is particularly important to develop corresponding precision casting molding raw materials and key heat treatment equipment, control and ensure the overall dimensional accuracy of large precision casting structural parts, meet design requirements, and shorten the development cycle.

Product introduction

The one-shot investment casting process has been widely used. Taking an engine STME in the United States as an example, the engine widely adopts the one-step precision casting process, which reduces the number of combustion chamber parts by more than 50, and reduces the number of welding by about 90, and the manufacturing cost is significantly reduced. At present, investment casting technology is mainly used in the manufacture of aluminum alloys, magnesium alloys, titanium alloys, superalloys and other parts in the aerospace field. sunbright focuses on the research and production of aluminum alloys, combined with SLA printing technology, can better produce suitable products for the aerospace field.

Aluminum alloy has the advantages of low density, high specific strength, good corrosion resistance, easy forming and low cost, so it has been widely used in the aerospace field. Aluminum alloy precision casting technology refers to the casting of large, thin-walled, complex, integral, high-performance aluminum alloy components without or with a small margin. The outline size is generally about 1500mm, and the wall thickness is generally about 3mm. The performance of the casting basically reaches the performance of medium deformation alloy Indicator, no or less machining allowance.

Product tolerance：+/-0.005mm
