In modern injection molding, more and more products feature complex geometries—deep cavities, slender inner tubes, ultra-thin walls, and curved transitions are now the norm.
In modern metal stamping, flanging is a key process in the manufacture of complex sheet metal parts, widely used in the production of structural components such as automotive bodies, appliance housings, and connecting flanges.
In a mold system, the back mold pin, as a key component of the ejection mechanism, plays a crucial role in smoothly ejecting the molded part from the mold cavity.
For the "high-chip area" in the long axis direction of the car oval punch needle, a main chip groove needs to be designed as the core chip removal channel.
In modern stamping die manufacturing, flanging needles, as key actuators for sheet metal edge forming, are widely used in flanging, drawing, and various composite forming dies.
The car oval punch needle utilizes self-lubrication and a low-friction material, significantly improving work efficiency and reducing energy consumption while also significantly enhancing the user experience.
