Sep 05, 2018

There are two major categories of sand casting and special casting.

1. Ordinary sand casting, using sand as a molding material, also known as sand casting, sanding, including wet sand type, dry sand type and chemical hardening sand type, but not all sand can be used for casting. The advantage is that the cost is lower because the sand used in the mold can be reused; the disadvantage is that the mold is time-consuming to manufacture, the mold itself cannot be reused, and the finished product can be obtained after being destroyed.

1.1 Sand type (core) casting method: wet sand type, resin self-hardening sand type, water glass sand type, dry type and dry type, solid casting, negative pressure molding.

1.2 Sand core manufacturing method: It is selected according to the size, shape, production batch and specific production conditions of the sand core. In production, it can be divided into manual core making and machine core making.

2Special casting, according to the modeling material, can be divided into special castings with natural mineral sandstone as the main modeling material (such as investment casting, clay casting, shell casting, negative pressure casting, solid casting, ceramic casting, etc.) Special castings with metal as the main casting material (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.).
