[0002] The brake pot is also known as the brake drum, which is a kind of brake hub. The brake pot on the electric tricycle is mostly made of cast iron, and its processing precision requires strictness. Sand casting is a casting method for producing castings in sand molds, and the sand box is an important tool in casting.

[0003] However, when the sand boxes are currently spliced ​​and combined, they are often mostly connected by gravity.
