Tricycle Steel Wheel Rims Manufacturers

What are the surface treatment processes for Tricycle Steel Wheel Rims?

In modern manufacturing, surface treatment processes play a vital role in improving product performance, durability and appearance quality. As one of the core products of Zhejiang Tianzhou Wheel Co., Ltd., Tricycle Steel Wheel Rims adopts a series of advanced surface treatment processes to ensure its excellent performance in various use environments.
Pickling process
Pickling is the preliminary process of steel surface treatment, and its main purpose is to remove oxides, rust and other impurities on the steel surface. In this process, the wheel rim is immersed or sprayed with an acid solution of a specific concentration (such as hydrochloric acid or sulfuric acid). After pickling, the steel surface will appear smooth and clean, laying a solid foundation for subsequent treatment processes such as phosphating and electrophoresis. Pickling not only significantly improves the adhesion of subsequent coatings, but also effectively prevents the coating from falling off due to surface residues.
Phosphating treatment
Phosphating treatment is an important process for forming a protective film on the surface of steel. In this process, the steel wheel rim is immersed in a phosphate solution, and a microscopic phosphate film is generated on the surface of the steel. This film not only has excellent corrosion resistance, but also enhances adhesion, effectively preventing steel from oxidizing in a humid environment. At the same time, phosphating provides a more ideal base for the subsequent coating process, ensuring the uniformity and stability of the coating.
Electrophoretic coating
Electrophoretic coating technology is an efficient and environmentally friendly coating method, widely used in many industries such as automobiles and home appliances. In the production of tricycle steel rims, the electrophoretic coating process is used to promote the uniform deposition of the paint on the rim surface through the action of the electric field. The main advantages of this process include:
Uniformity: Electrophoretic coating can ensure that the coating is evenly covered on the rims of complex shapes, avoiding the uneven coating phenomenon that may occur in traditional spraying.
Strong adhesion: Since the paint is deposited on the metal surface through the action of the electric field, the adhesion of the coating is significantly enhanced, which can effectively resist peeling and shedding.
Environmental protection: The paint utilization rate in the electrophoretic coating process is high, and less waste is generated, which meets modern environmental protection standards.
Spraying process
After the electrophoretic coating is completed, the spraying process is further carried out to improve the appearance and durability of the rim. The spraying process usually uses high-performance polyurethane or epoxy resin coatings, which have excellent wear resistance, corrosion resistance and UV resistance. The spraying process includes several key steps:
Surface pretreatment: Before spraying, ensure that the rim surface is clean, free of oil and dust to improve the adhesion of the coating.
Spraying operation: Use a high-pressure spray gun to evenly spray the paint onto the rim surface to ensure that every corner is covered.
Curing process: After spraying, the rim enters the drying oven for curing to ensure the hardness and stability of the coating.

How to choose the raw materials for Tricycle Steel Wheel Rims

In modern manufacturing, the quality and performance of products are directly affected by the selection of raw materials. Zhejiang Tianzhou Wheel Co., Ltd. As an industry leader, the selection of raw materials for one of its core products, Tricycle Steel Wheel Rims, is particularly important. The company always adheres to the principles of high standards and high requirements to ensure the excellence of the final product in terms of performance and market competitiveness.
Advantages of high-strength low-alloy steel
The steel wheel rims of tricycles are mainly made of high-strength low-alloy steel (HSLA) as raw materials. This material has several significant advantages:
High-strength characteristics: The tensile strength and yield strength of high-strength low-alloy steel are significantly higher than those of ordinary carbon steel, and it can withstand greater loads. It is particularly suitable for bearing the pressure generated by tricycles when transporting heavy objects and the impact during driving.
Excellent toughness: The material can still maintain good toughness in low temperature environments, reducing the risk of fracture under extreme climatic conditions and ensuring safety in various environments.
Corrosion resistance: The addition of appropriate amounts of alloying elements (such as chromium, nickel, molybdenum, etc.) to high-strength low-alloy steel significantly improves the corrosion resistance of the material, extends the service life of the rim, and reduces maintenance costs.
Selection criteria for raw material suppliers
In order to ensure the high quality of raw materials, Zhejiang Tianzhou Wheel Co., Ltd. has established long-term cooperative relationships with many well-known steel suppliers. In the selection process of suppliers, the following aspects are mainly considered:
Qualification certification: All suppliers must have international quality management system certifications such as ISO9001 to ensure that their products meet international standards and maintain product reliability.
Production capacity: Select suppliers with stable production capacity and good reputation to ensure timely supply of raw materials so as not to affect production progress.
Quality control system: Suppliers need to have a complete quality control system and be able to provide detailed raw material quality inspection reports to ensure the qualification of each batch of materials to meet production needs.
Physical and chemical property inspection of raw materials
Before purchasing raw materials, Zhejiang Tianzhou Wheel Co., Ltd. will conduct strict physical and chemical property inspections to ensure that they meet the design requirements. The main inspection items include:
Chemical composition analysis: Through advanced technical means such as spectral analysis, the content of carbon, manganese, silicon, chromium, nickel and other elements in steel is detected to ensure that it meets the standards of high-strength low-alloy steel.
Mechanical property testing: Tensile tests, impact tests, etc. are carried out on raw materials to detect key indicators such as tensile strength, yield strength and elongation to ensure their safety and reliability in actual use.
Hardness test: The hardness of the material is tested by equipment such as Brinell hardness tester or Rockwell hardness tester to ensure that it has sufficient wear resistance during use and extend its service life.
Storage and management of raw materials
The storage and management of raw materials are also crucial. Zhejiang Tianzhou Wheel Co., Ltd. has taken a series of effective measures in the storage of raw materials:
Moisture-proof and rust-proof: Steel should be stored in a humid environment to prevent rust. The company uses moisture-proof agents in the warehouse and regularly checks the status of the materials to ensure that they are always in good condition.
Classification management: Classify and manage steel according to different specifications and types to ensure that the required materials can be found quickly during the production process, thereby improving production efficiency.
Regular inspection: Regularly inspect the inventory raw materials to ensure that their quality and status meet production requirements, and promptly remove unqualified materials to ensure the smooth progress of production.
