During the production process of cast iron floor plates, there will be a part of the deviation of the theoretical weight. It should be noted that the deviation of the cast iron floor plates will affect its usage.

The cast iron measuring platform is used for power experiments of machinery and engines, equipment debugging, and has good plane stability and toughness. The surface has a T-shaped groove, which can be used to fix the experimental equipment.

The non-machined surface and appearance quality of machine tool castings have a considerable impact on the commercial properties of the castings.

In order to gain good quality lost foam castings, each manufacturing process must be strictly controlled from the purchase of raw materials, modeling, sand falling, and cleaning of the castings. A slight improper operation will cause various defects in the castings.

The cast iron platform is made of HT250. The main ingredient is iron. Iron is a material that is easy to rust. Especially in rainy weather, the cast iron platform is more likely to rust when exposed to rain. Therefore, the cast iron platform must be rainproof and waterproof during transportation and use.

To improve the overall performance of ductile iron parts, it is necessary to eliminate the points of white-mouth annealing, normalizing, quenching, and ductile iron annealing, which will be described in detail below.
