Nylon (PA), as one of the most widely used engineering plastics, boasts high strength, wear resistance, and chemical corrosion resistance, making it suitable for auto parts, electronic casings, mechanical structural components, etc. The design and manufacturing of its injection molds must closely match the material properties to ensure stable produ

As a core production equipment, precision injection molds directly determine the molding quality, performance stability, and market access qualification of medical components. Suzhou Donghao Precision Manufacturing Co., Ltd. has been deeply engaged in the medical field for 17 years. Relying on integrated molding technology accumulation and complian

High-temperature plastic materials (such as PEEK, PEI, PSU) are widely used in high-end fields like semiconductors, new energy, and medical devices due to their excellent heat resistance, corrosion resistance

In the relentless pursuit of manufacturing excellence, where the slightest deviation can compromise product integrity, the sophisticated tools that shape our modern world often go unnoticed by the end-user.

his philosophy is not only integrated into every link of mold design, manufacturing and testing, but also becomes the cornerstone of Donghao Precision's deep cultivation in the global high-precision manufacturing market.

The foremost consideration is precise and often elevated mold temperature control. Materials like PPS and certain PA grades require high mold temperatures (often 130°C-160°C) to ensure proper crystallization and prevent premature freezing, which leads to poor surface finish, high stress, and short shots. This demands robust mold heating systems,
