This sand cast aluminum alloy bearing seat has a cylindrical main structure, with evenly distributed flange mounting ears with mounting holes on the outer wall. The ears are connected to the main body with triangular reinforcement ribs, and hollow areas are formed between the ribs. All corners and connecting parts are rounded and transitioned without sharp edges. The overall sand cast texture is neat, compact, and the lines are smooth.
Step 1: We first adapt the high precision sand moulds according to the structure of the product, introduce the molten aluminum under controlled pressure into the mould cavity and ensure the complete formation of complex contours and internal structures.
Step 2: The rough castings undergo manual sand removal and shot blasting to thoroughly eliminate surface sand and casting burrs.Next, proceed to the precise processing step: CNC Milling machines are used for fine milling of the reference surface for assembly of parts, and the equality is controlled within 0.03mm; reuse the integrated CNC drilling and decoupling equipment to perform mixed material drilling and decoupling processing on all positioning holes, ensuring that the intake at the drilling site is within ± 0.02 mm.
Step 3: Finally, perform natural anodizing to obtain a dense oxide film on the surface by electrochemical reaction, which greatly improves the corrosion resistance and surface hardness of sand melted parts.
As a professional manufacturer of CNC processing services, Dongguan Shengpeng Precision Technology Co., Ltd. offers complete process services, from customer service for lithium sand to finished product delivery. Not only do we support the individual adaptation of dimensions, material and surface treatment, but we also optimize the construction of the sand moulds for your working conditions, so that each sand foundry part of the foundry can be precisely adapted to practical application scenarios. Regardless of what you want to adjust the wall thickness of the cast iron or replace it with a stronger alloy material, we can react quickly and perform it at the bottom.
