## VII. Introduction to high-quality product parts
- **High-quality raw materials**: The product parts provided by the company are all 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 have been strictly screened and have 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. In addition, when manufacturing seals, high-performance rubber materials are selected to ensure that they can still maintain good sealing performance under high temperature, high pressure and chemical corrosion environments.
- **Exquisite manufacturing process**: The company uses a series of advanced manufacturing processes to ensure the high precision and high performance of product parts. For example, in the process of parts processing, five-axis linkage machining centers are widely used, which can realize the precision processing of complex-shaped parts, and the dimensional accuracy can reach the micron level. In terms of heat treatment technology, 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, such as valves and piston rings, 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.
- **Strict quality inspection**: The company has established a complete and strict quality inspection system. From the entry of raw materials to the exit of finished products, it must go through multiple strict inspection processes. When the raw materials enter the factory, strict chemical composition analysis and physical property testing are carried out to ensure that the raw materials meet the standards. During the production process, precision testing 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 conventional appearance inspection and dimensional measurement, non-destructive testing and performance testing will also be carried out on the parts. For example, ultrasonic flaw detection is carried out on the crankshaft to ensure that there are no defects such as cracks inside; the piston is subjected to a heat load test simulating actual working conditions to verify its reliability under high temperature and high pressure environments. Only products that pass all inspections can enter the market and provide customers with high-quality and reliable products.
