## VII. Introduction to high-quality product parts
1. **High-quality raw materials**: All product parts are selected from the world's top raw material suppliers to ensure that the quality of raw materials reaches the industry-leading level. For example, in the manufacture of pistons, the aluminum alloy materials used are strictly screened, with high strength, low density and good thermal conductivity, which can effectively reduce the weight of the engine and improve the heat dissipation efficiency. In the selection of alloy steel for manufacturing crankshafts and connecting rods, the chemical composition and physical properties are strictly controlled to ensure that the materials have sufficient strength and toughness to withstand the huge stress when the engine is running at high load.
2. **Exquisite manufacturing process**: The company uses advanced manufacturing processes, such as five-axis linkage machining centers for precision machining, to ensure that the dimensional accuracy of parts reaches the micron level. In terms of heat treatment process, advanced technologies such as vacuum quenching and tempering are used to accurately control the hardness, toughness and wear resistance of parts, so that the parts can maintain good performance under different working conditions. For some key parts, laser cladding technology is also introduced. By cladding a layer of special alloy on the surface of the parts, the hardness, corrosion resistance and wear resistance of the parts surface are further improved, and the service life of the parts is extended.
3. **Strict quality inspection**: A complete and strict quality inspection system has been established. From the entry of raw materials to the exit of finished products, multiple strict inspection processes must be carried out. When the raw materials enter the factory, strict chemical composition analysis and physical property inspection are carried out to ensure that the raw materials meet the standards. During the production process, precision inspection equipment such as three-coordinate measuring instruments and roughness meters are used to monitor the dimensional accuracy and surface quality of parts in real time. In the finished product inspection stage, in addition to the routine appearance inspection and dimensional measurement, non-destructive testing and performance testing will also be performed on the parts. For example, ultrasonic testing is performed on the crankshaft to ensure that there are no defects such as cracks inside; the piston is subjected to a thermal load test simulating actual working conditions to verify its reliability under high temperature and high pressure environments. Only products that pass all tests can enter the market and provide customers with high-quality and reliable products.
