Cast flat plate/machine table is made of pig iron smelted and poured into iron castings, and then made by sand falling, heat treatment, machining, scraping, painting, cleaning and other processes. It can be used for inspection, scribing, measurement, assembly, welding and other functions.

The cast iron working platform can be made into the iron bottom plate base of test benches,inspection benches etc. There are many process steps in the manufacturing process, and the process requirements are high. Therefore, you should pay attention to the control of some important nodes to get one high-quality plate.
A reasonable preliminary plan is a prerequisite for manufacturing. Firstly, understand the load-bearing load, whether there is dynamic load, etc., then the form of installing and design of the casting plate is also very important. The thickness of the working surface depends on the size of the load, whether with or without T-slots, etc., and the thickness of the enclosure should increase with the increase of the thickness of the working surface, strengthen the same is true for the ribs, and the total height of the casting platform is also designed according to the size of the area and the size of the bearing capacity. Generally, the total height of the narrow and long plate needs to be increased to deal with the problems of overall bending and deformation.
In the casting process, the casting platform with a higher total height needs to increase the riser and extend the cooling time of the pit before shipment, so as to reduce the deformation of the casting as much as possible.
The heat treatment of castings before processing is an important node that must be kept in mind. At this time, an effective means to prevent the deformation of cast flat plate/casting platform products is also a crucial means. Removing the internal stress of castings is a recognized prevention in the industry.
During processing, each data gate must be carefully controlled according to the drawings. The cast iron platform with T-slots must be left with a margin for secondary processing before the processing is completed. After three to four days, the secondary processing will be carried out. The reason is that the working surface will be slightly deformed when the T-slot is processed. The secondary processing is an effective method to solve this deformation.
