The event. On behalf of the District Committee and Huishan Economic Development Zone, Yang Jianping expressed his gratitude to the guests present at the promotion meeting. He said that the whole vehicle and auto parts industry has long been the leading industry for the key development of Huishan Economic Development Zone. At present, five auto companies such as the above-mentioned automobile commercial vehicles and FAW buses have been formed as the leading enterprises, FAW Xichai and FAW. More than 40 well-known domestic and foreign auto parts companies, such as Foundry, Weifu Lida, Dutch AWL, German Singer, and American Fuzhuo, are the industrial chain supported by them, and have successfully ranked among the “Jiangsu Auto Parts Industry Baseâ€. Wuxi Huishan Economic Development Zone warmly welcomes more auto parts manufacturers at home and abroad to invest in Xingye and jointly build Wuxi Huishan SAIC commercial vehicle parts industry supporting area. At the promotion meeting, the first batch of 12 projects signed on the spot, involving automobile wheel assemblies, automobile body molds, and automobile logistics. In addition, the supporting area also signed the automobile engine production and research base of Tongji University with the Automobile College of Tongji University, which will provide strong technical support and abundant human resources for the development of the automotive industry in the region. In the next five years, with the completion of a number of key projects such as the SAIC commercial vehicle Phase III pickup truck project and Jingke Bus, the automobile industry in the development zone will form an industrial scale of 50 billion yuan. Huishan SAIC Commercial Vehicle Parts Industry Supporting Area is located in Wuxi Huishan Wind Power Technology Industrial Park. It covers an area of ​​more than 1000 acres and involves many functions such as manufacturing, technology research and development, warehousing and logistics. It is the “Tenshan Economic Development Zoneâ€. The key projects during the 2nd Five-Year Plan period are also the demonstration areas for regional transformation and upgrading. Casting Polyurethane Prepolymer Casting Polyurethane Prepolymer used for making wheels, Sieve, machinery parts, sealing ring, PU rollers and other elastomers.

Casting polyurethane prepolymers involves a process where a liquid mixture of polyols and isocyanates is poured into a mold or container and allowed to cure or solidify. This process is commonly used in various industries such as automotive, construction, and manufacturing.

Here is a step-by-step guide on how to cast polyurethane prepolymers:
1. Prepare the mold: Clean the mold thoroughly and ensure it is free from any debris or contaminants. Apply a mold release agent to facilitate the easy removal of the cured polyurethane.
2. Measure and mix the components: Measure the desired amount of polyol and isocyanate components. The specific ratio will depend on the desired properties of the final product, which can be found in the product's technical data sheet. Pour the measured components into a clean mixing container.
3. Mix the components: Use a mechanical mixer or a high-speed drill with a mixing attachment to thoroughly mix the polyol and isocyanate components together. Make sure to mix for the recommended amount of time specified by the manufacturer to ensure complete homogeneity.
4. Degassing: After mixing, it is important to degas the mixture to remove any trapped air bubbles. This can be done by placing the mixture in a vacuum chamber and applying vacuum pressure for a specified period of time. Alternatively, a vacuum degassing unit can be used.
5. Pouring the mixture: Once the mixture is properly degassed, pour it into the prepared mold or container. Take care to avoid introducing any additional air bubbles during the pouring process.
6. Curing: Allow the poured mixture to cure at room temperature or, if necessary, in a temperature-controlled environment. The curing time will vary depending on the specific polyurethane prepolymer used and the desired hardness or flexibility of the final product. Follow the manufacturer's recommendations for curing time and temperature.
7. Demolding: After the polyurethane has fully cured, carefully remove it from the mold or container. Use caution to prevent any damage to the cured part.
8. Post-curing (optional): Depending on the specific polyurethane prepolymer used, post-curing may be required to optimize the material's properties. This can be done by subjecting the cured part to elevated temperatures for a specific period of time.
It is important to note that casting polyurethane prepolymers requires proper safety precautions, such as wearing appropriate personal protective equipment (PPE) and working in a well-ventilated area. Always follow the manufacturer's instructions and guidelines for handling and working with polyurethane prepolymers.
