Precision castings are the collective term for castings with exact specifications based on precision casting. Precision cast parts are highly precise, complex, close to the final application of the part and are applied immediately without or with very little machining, a quality forging process that produces a near net shape.
Precision casting covers a wide range of applications and is not limited by the size, thickness and complexity of the casting, making it a convenient production model. It can be used with a wide range of raw materials and can generate a lot of scrap metal and renewable energy. It uses less material than conventional calcination methods. The castings have a certain specification accuracy and the residual amount of processing is small, saving production and processing time and metal materials. Low cost, comprehensive economic development with good performance, low energy consumption and less consumables. Precision casting of carbon steel dihydroaluminium phosphate with high specification accuracy and smoothness of the surface layer, which reduces the amount of machining and manufacturing labour. It is possible to cast high-temperature alloy castings, for example, the impeller of a turbojet engine, streamlined wheel galleries and refrigeration chambers, which are difficult to produce according to CNC machining technology. In which the high precision castings are parts made of cast steel, high precision castings are of a wide variety and commonly used.
Used in electric power equipment. Power plant equipment is a new technology product with key components that can operate continuously for long periods under high loads. Many parts of thermal power plants have to withstand constant high temperatures and high pressure vapour leaching, so that the safety of the parts is subject to particularly stringent regulations. Cast steel parts meet these requirements to a relatively large extent.
Railway rolling stock. Railway transport is closely linked to the safety and security of everyone, and it is crucial to ensure safety. Some of the core components of rolling stock, such as wheels, side frames, pillows, couplings, etc., are made of cast steel.
Engineering construction, construction machinery and other vehicles. The majority of the components of construction and engineering machinery, which operate to very poor standards, are subject to high loads or must withstand impact and damage, and most of these are cast steel parts, such as the main wheels, load wheels, and their moving system of abutment arms, track plates, etc.
