Lianyungang Landmark Co., Ltd was established in 1992. In 2006, we built our factory, Tianjin Jingcheng High-Pressure Pump Manufacturing Co., Ltd, focused on the research and manufacturing of ultra-high-pressure pumps and cleaning machines. With the business philosophy of "credit is the basis, quality is the first," we continuously research and design exquisite equipment to win the trust of both old and new customers, and develop together with all our clients.
We invested over 80 million RMB for the factory building in the "Bohai Economic Center," located in the Jinnan Shuanggang Industrial Park. The factory covers an area of 8,000 square meters, and we also invested over 10 million RMB to purchase high-precision CNC lathes, milling machines, grinders, and other advanced production equipment. Our workforce consists of nearly 100 highly skilled employees, two-thirds of whom are senior technical and management staff.
As a high-tech enterprise, our company integrates research, production, sales, and service, always committed to technological innovation and R&D of high-pressure reciprocating piston pumps and high-pressure water jet equipment. We collaborate with well-known international companies to bring advanced technology and international standards, developing a series of high-pressure pumps used across industries such as petroleum, coal, chemicals, power, machinery, metallurgy, food, pharmaceuticals, textiles, and descaling hot-rolled steel. We also provide customized high-pressure pump solutions and high-pressure water jet cleaning technology consulting and equipment sets for our customers.
Our pump series products and complete cleaning equipment sets have been widely praised by users, known as "international quality" and "domestic price" high-end products. After years of development, we have successfully built the brand "Jingcheng" from Tianjin to China and beyond. Our high-pressure pumps and water jetting equipment have passed ISO9001 quality management system certification, health, safety, and environmental management system certification, and mining product safety certification. Through continuous R&D efforts, we have obtained national patents, giving us unique technical advantages and strong brand competitiveness in the market.
We are deeply grateful to all our pump and cleaner users at home and abroad for their support and trust. We will continue to provide quality products and excellent service.

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.
