Fe clip on wheel weights production process

We uphold the principles of the high quality raw material produce high quality products . Excellent cooperation with Chinese large steel mills, such as: Shanghai Baoshan Iron and Steel, Xinyu Steel and so on. Clips select high-quality spring steel, disc-shaped block made of high quality steel, are customized sectional material. According to our needs adding special metal elements, so that our products wheel weight with strength but also flexibility, the premise of ensuring the strength, more agreeableness during use. Each batch of wheel weight  raw material into the plant  must submit material inspection sheet, we each batch of raw materials are strictly mass discrimination, thus good product-related checking .

After the raw materials into the plant to undergo a rigorous test, began to enter the production process. We uphold the well-equipped technology, sophisticated technology, strict tolerance control standards and strict requirements of the rules. The first step will make the wheel weight clips mold debugging to the best, and then a high-performance 65 Mn spring steel filled into the feed opening into the wheel weight of clips molding press. The clips stamping the test program is very important, it relates to the wheel weight rim installation firmly or not . After more than 35% time to time sampling, we can effectively reduce and eliminate the presence of defective products. After the clips stamping molding,  hardening, heat treatment, according to the technological requirements for galvanized or combined with block.

 

Block part of the production to be first using disc-shaped wire drawing , after accurate calculation program is record by computer. Disc-shaped wire is cut off in turn, the next program will be truncated cylinder block forming a cold pier, this part of the block is the critical control points of appearance quality, so the quality control personnel to block press-molded sample testing rate up to 35%, in order to reduce the presence of defective products guarantee. All defective once discovered they do abandon treatment. Finished block according to specifications to storage .

Further according to the customer's surface processing technology and production process. For more than 300 hours of salt spray test, do Dacromet surface treatment.   Use quench but not galvanized clips of wheel weight according to specifications and blocks start riveting molding. After finish can be sent dacromet treatment plant to do surface treatment .

Surface treatment can accept below 300 hours salt spray test ordercan distinguish the block according to specifications, performed peracid rust galvanizing process. This step is to avoid confusion specifications, reduce the workload for riveting clips and blocks. Whether wheel weight do dacromet or galvanized spray, riveting process is a vital part. It concerns the clips and block perfect combination. So we go through the early development, the development of zero error riveting system to safe guard the clips and blocks riveting perfect.

Galvanized clips and blocks finish riveting have to go through three inspection process: that is, before the riveting of the clips and blocks inspection, the riveting process on the clips  and block and riveting perfection and robustness testing, after completion of riveting overall product testing. Finally, the qualified products to enter the next appearance treatment process - spray coating . We have chosen to use spray materials are brand "goldfish"  and "huarun "other domestic and international brands, to ensure that the harmful substances below the national standard and European Union standard. Finally, the synthetic appearance of perfect wheel weight packaging and storage.
