Product Sample :③ Special Heading Dies Material: WC-Co
Technology: Die-sinking and irregular micro-processing using wire-cut EDM ⇒ Mirror-finish by lapping
Products: Pins, contact points, and parts
Structure: (Left) Diameter of outer circular hole is 5mm. This die has a seamlessly integrated structure and does not involve nibs.
(Right)2-part dies made of opposing shapes. The parts that come in contact with products are created in precision so that there
will be no space in between, preventing burrs when manufacturing products with dies.

Nib: Upper half has circular hole and lower half has an
o-shaped hole. Four rectilinear holes are formed by combining four parts.
Product Sample④：Nib of combination dies
Material： WC-Co
Technology： Irregular ultra-precise micro machining by wire-cut and die-milling EDM ⇒ Mirror finish provided by lapping
Products： Screws or parts with complex configuration
Note： Nib can be replaced when broken.
We can manufacture ultra-thin parts of 0.5mm thickness. We can also create paired dies stacking several nibs.
