Precision casting components and structure?
Release time:
2023-09-18
Precision casting parts are workpieces manufactured using the casting process with high precision, high surface flatness and complete internal structure. Its composition and structure vary depending on the type of workpiece, and can generally be divided into the following aspects:
Base material: the base material of precision casting parts is usually metal materials, such as iron, aluminum, copper, titanium and so on. These metal materials have good strength and heat resistance, suitable for the manufacture of precision parts need to withstand a certain load.
Casting materials: the casting materials for precision casting parts are usually metal alloys, such as cast iron, stainless steel, nickel-based alloys, etc.. These alloys have excellent physical, chemical and mechanical properties, to meet the requirements of precision casting parts.
Shape and structure: the shape and structure of the precision casting parts are varied, including size, shape and surface features and other aspects. Their design and manufacture need to be based on the specific working environment and working requirements for selection, to ensure that precision casting parts can work properly and meet the expected performance indicators.
Internal structure: the internal structure of precision casting parts mainly refers to its organizational structure and pore structure. Organizational structure, including grain size, grain shape, phase composition and defects, etc., on the performance and reliability of precision casting parts have an important impact. Pore structure refers to the impurity structure including pores, inclusions and defects, etc., which may lead to the strength and sealing of the precision casting parts reduced.
Surface treatment: precision casting parts usually need surface treatment after casting to improve their finish and corrosion resistance. Common surface treatment methods include mechanical polishing, laser marking, electroplating and coating.
In addition to the above aspects, the structure of the precision casting parts may also include enameled wires, seals, inserts and so on. Enameled wires are used to insulate and encapsulate circuit components, seals are used to ensure the sealing performance of precision casting parts, and inserts are used to fix and connect other parts.

What are the advantages of precision castings compared to traditional casting technology?
Precision castings offer many advantages over traditional casting techniques in many ways. The following are some of the main advantages: 1. Higher precision: Precision castings can provide higher precision and control of dimensions. Using CNC technology, more complex and precise parts can be produced to meet a variety of requirements. In contrast, the accuracy of traditional casting technology is limited by the accuracy of the models and molds produced, which usually makes it difficult to guarantee parts with high precision requirements.
