Before we introduce EDM process, we would like to have an overall introduction to injection mold structure. An injection mold consists of mold base, cavity, core, injection channel, ejection system, and other mold components if needed(hot runner system).
We out-source mold base and other components(like sleeve, ejection pins, nut), but the mold cavity and core must be manufactured by our-self.
In the mold making industry, there are lots of different type of mold making machines to use, like CNC milling, wire cutting, grinding machining, drilling, and EDM machining.
EDM is known as electrical Discharge Machining, plays a very important roles in the mold making technology, which mainly used to achieve some deep and narrow profile that a normal CNC machining could not work for.
At Inno molding, we are well-equipped with 10 sets of normal EDM and 5 sets of mirror EDM that exported from Switzerland and Japan.
Prior to EDM machining, all of our electrode tool must be fully measured to ensure accurate dimension we will obtain. Here below you can review our EDM manufacturing process.
