Problem Description:

In the process of manufacturing EN877 pipes for European clients, we faced the technical challenges of producing the world's smallest size DN50 and largest size DN600 cast iron pipes. This involved precision machining of small-size molds to ensure products met the highest size standards. For the manufacturing of DN600-sized pipes, we optimized iron fluidity to guarantee product quality and performance. Simultaneously, we took a comprehensive approach to production costs, successfully reducing overall costs through material selection and process optimization.

Our Solution:

Firstly, we collaborated closely with a specialized mold factory to customize molds for the smallest size, ensuring they fully complied with EN877 product standards. This not only required high technical proficiency but also stringent control over product quality to meet the demanding production requirements. Secondly, we conducted multiple detailed tests aimed at finding the optimal iron temperature and composition. The key to this step was ensuring sufficient time for the iron to flow and cool uniformly in the molds during the condensation process, ensuring product quality and performance. Finally, we employed unique coating technology that effectively controlled the production costs of the largest size product by increasing the yield rate. This innovative technological approach not only contributed to cost reduction but also improved production efficiency, providing customers with a high-quality and cost-effective solution.

Achievements:

We successfully demonstrated the technical feasibility of producing the smallest size products, filling the market demand gap for such products. This provided customers with a more comprehensive product line, enabling us to meet the diverse needs of different customer segments. Simultaneously, we successfully produced the largest size products, addressing the market's absence of such products. This not only expanded the product's application range but also further solidified our leading position in the industry. In terms of coating technology, we introduced unique technical means, achieving significant breakthroughs and contributing to the innovation of coating technology. This innovation not only increased the yield rate of the largest size product but also maintained high-quality products while reducing production costs. This signifies that we not only gained an advantage in product design but also achieved higher efficiency and economic viability in the production process.
