Engine Housing Gravity Casting Components

The engine housing is made of 6061-T5 aluminum alloy by gravity melting, then machined and surface treated to complete production. The upper part of the shell is a wide intake manifold cover plate, with multiple longitudinal reinforcement ribs and groove type guide channels; The central part adopts CNC engraving or laser engraving to produce clear markings; multiple cylindrical convex interfaces, with high coaxiality and regular arrangement of threaded holes to ensure sealing and stable assembly; The edge is equipped with several sets of mounting holes for evenly arranged bolts and adopts an embossed construction, to ensure a smooth and non-protruding surface after locking.

Step 1: Complete the forming process through the Gravity Casting Service, spray preheated aluminum alloy AL6061-T5 into a special mold, fill the cavity of the mold under the effect of gravity naturally, and first form the complex cavity, airways, mounting flange and other basic structures of the shell. At the same time, it strictly controls the outlet temperature and cooling speed, to reduce defects such as porosity and shrinkage and to ensure the density and structural integrity of the vacuum.

Step 2: Enter the precision machining process. The cast blank is subjected to deburring and cleaning sand pretreatment. Subsequently,  through the Precision Gravity Non Standard Parts precision machining scheme, high-precision CNC equipment is used to Perform drilling and manufacturing processes, accurately removing casting allowances, completing airway finishing, installation hole boring, and sealing surface mirror machining. The overall measurement tolerance is stably controlled in the micrometer range, which ensures a precise adjustment and a reliable position between the housing and engine components.

Step 3: After treatment and formation, the product is subjected to a natural hard anodizing treatment, using electrochemical reactions, to form a dense layer of aluminum oxide protective film on its surface, the original metallic color of the aluminum alloy being obtained, by significantly improving the wear resistance, corrosion resistance and insulation performance of the shell.
