Why small cast iron platforms generally use resin sand

Resin sand is generally used on small cast-iron platforms.On the one hand, it is for the convenience of sand removal. There are also the following reasons: First, relatively speaking, lost foam casting is used for the production of single pieces or small batches of automobile cover parts, machine tool beds and other large molds. Compared with traditional sand mold

Brief Analysis of Material Characteristics of Gray Cast Iron, Ductile Iron, Cast Steel

Gray cast iron is a type of cast iron containing flake graphite, which is the most widely used cast iron. Its output accounts for more than 80% of the total cast iron output. The gray cast iron material has low comprehensive mechanical properties and high compressive strength, which is 3 to 4 times its own tensile strength. Vibration damping capacity is greater than steel 1

What does "three coordinate" mean in the coordinate measuring platform?

The measurement of the length of an object is based on the coordinates of points.It is divided into one-dimensional, two-dimensional, and three-dimensional measurements in space.The three coordinates are the specific values of the three coordinate positions on the x, y, and z axes. Computer data processing
