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,

In the world of precision injection molding​, success isn’t just about hitting a target dimension once—it’s about holding it consistently, from the first shot to the millionth. For industries like medical devices, micro-optics, and advanced electronics

Many mold failures stem from choosing a standard-grade steel for an application that demands more. Wear, corrosion, and plastic pressure can quickly degrade a poorly matched mold.

Automotive connectors operate in environments ranging from -40℃ to 150℃, and must withstand vibration, chemical corrosion, etc. Material selection should focus on "scenario adaptation
