1. Imported star-type retaining washers: Some imported products may use higher-end or special metal materials, such as certain aerospace-grade alloy steels and super stainless steels. These materials offer higher strength, hardness, fatigue resistance, and corrosion resistance, enabling them to adapt to extremely harsh working environments such as high temperatures, high pressures, high humidity, and strong acid-base conditions.
2. Domestic star-type retaining washers: They generally use common high-quality carbon steels, stainless steels, and other materials. For ordinary industrial applications and daily use scenarios, the material performance of domestic washers can usually meet the requirements. However, in some special fields with extremely high material performance requirements, there may be a certain gap compared with imported products.

In Terms of Manufacturing Processes

1. Imported star-type retaining washers: Some advanced foreign manufacturing enterprises may have more mature technologies and experience in production processes. For example, in processes such as stamping, forming, heat treatment, and surface treatment, they can achieve higher precision and consistency. The dimensional tolerance control of the washers is stricter, and the geometric tolerances such as flatness, perpendicularity, and roundness are smaller. The processing accuracy of the tooth profile or retaining structure is higher, allowing better coordination with screws to exert the retaining effect.
2. Domestic star-type retaining washers: Although domestic manufacturing processes have made significant progress in recent years, overall, compared with imported products, there may still be room for improvement in the manufacturing of some high-precision and complex processes. In mass production, the consistency and stability of products may be slightly inferior.

In Terms of Product Standards

1. Imported star-type retaining washers: They follow some advanced international standards or high standards of foreign enterprises themselves, such as Germany’s DIN standards and the United States’ ASME standards. These standards may be stricter or more detailed than domestic standards in terms of certain performance indicators and testing methods.
2. Domestic star-type retaining washers: They are mainly produced in accordance with national standards (GB) or industry standards. The basic performance and quality requirements can be guaranteed, but compared with advanced international standards, there may be differences in some details and high-end performance requirements.

In Terms of Price

1. Imported star-type retaining washers: Due to factors such as import tariffs, transportation costs, brand premiums, and higher R&D and production costs, their prices are usually higher than those of domestic star-type retaining washers.
2. Domestic star-type retaining washers: They have certain advantages in cost, with relatively lower prices. For application scenarios that are cost-sensitive and have less stringent performance requirements, domestic washers have higher cost performance.

In Terms of Brand and Market Positioning

1. Imported star-type retaining washers: Some internationally renowned brands have high popularity and reputation in the global market, and they are usually positioned in the high-end market. They mainly target industries and customer groups with extremely high requirements for product quality and performance, such as aerospace, high-end automobile manufacturing, and precision machinery.
2. Domestic star-type retaining washers: There are many domestic brands with diversified market positioning. Some brands target the mid-to-low-end market, providing cost-effective products for ordinary industrial and civil fields. There are also some enterprises that are moving towards the high-end market, striving to improve product quality and technical level to compete with imported brands.
