The wafer storage material box is processed by precision CNC machining of 6061 aluminum profile. The whole surface is sturdy and durable. The surface is oxidized by the anode and the surface is smooth and burr-free. The surface wear resistance is good, which can better protect the product and make it safer to use. The oxidized parts are assembled and verified by the teacher of 10 years of experience to ensure that the flatness of each product is ≤0.05mm, which is more in line with the requirements of large-scale precision cutting and dicing technology at home and abroad.
