To get the standard product, the casting manufacturer will strictly manipulate the pouring temperature during the pouring process. The pouring rate and other common problems. Therefore, it is very important that the pouring specifications are followed. Precision casting manufacturers in the process of pouring cast steel parts require attention to the following aspects.

1. about the pouring temperature, it is more harmful to the quality of the equipment, should be based on the type of material. The structure of the goods and their casting characteristics to clarify the effective pouring temperature operation scale. Regarding the pouring rate, in order to ensure that the vapour in the concave mould can be discharged smoothly, a higher pouring rate can be used for castings that are to be condensed together, while a lower rate can be used for castings that are to be fixed in order.

2. The pouring process requires compliance with the requirements: when pouring larger castings, the steel should be placed in the steel ladle for a period of time after pouring; after pouring, wait for condensation, after the immediate dismantling of the pressure iron and box card is required, which can reduce the frictional resistance of the casting, and also reasonably prevent the casting from causing cracks and defects. The cast steel parts about the field of all castings have a very big hazard, in the manufacturing process to be effective institutions at each stage, to improve the quality of castings, to promote the field of all castings.

To put it bluntly, the disappearing mould casting process, simply put, is to use fusible raw materials, such as wax or plastic made of fusible solid model, commonly known as sand casting or solid model, on which a number of layers of refined fire-resistant architectural coatings, through the dry and hard bottoming to produce a general shell, then use the casting casting machine steam or boiling water from the shell to melt off the solid model, followed by the precision investment casting shell placed in the sand box. The mould is then placed in a sand box, filled with dry sand around it and finally put into a calciner to be fired at high temperature, e.g. when a high toughness shell is chosen.
