Precision Dies for Quality Products
Tokyo Byora Koki Co,. Ltd.
Precision Dies for Quality Products
Tungsten Carbide Punches, Dies, and Pins
Top-notch, long-lasting die and punch manufacturing catering to your specific needs.
Since our inception, we have excelled in meticulously crafting tungsten carbide materials, second only to diamond in hardness. We specialize mainly in cold heading and forging dies and punches made from tungsten carbide. Our precision engineering ensures long-life and high-accuracy die and punch manufacturing. We excel in producing dies and punches for small-diameter precision parts, gaining high acclaim from manufacturers of precision electronic components like small screws and sensors.
Specialized Processing Techniques
Unparalleled Expertise in Processing Challenging Materials
Our expertise in handling challenging materials like tungsten carbide, titanium carbide, iridium carbide, and high-speed steel stands unparalleled:
1. Micro & Deep Hole Processing:
Capable of handling minimum hole diameter of 0.1 mm and deep holes from 1 mm, finding applications in medical, aerospace, and semiconductor precision parts.
2. Special Hole Processing:
Shape-EDM electrodes are required for special hole processing in hard materials, considering friction during part processing to extend product life with high surface roughness. We have a rich history of accomplishments in this demanding field.
3. Lapping (Mirror Processing):
Lapping is crucial for product longevity, showcasing the finesse of our artisans. It takes five years to master this skill, a legacy well-maintained by our team.

Tungsten carbide Die and Punch Tokyo-ACE
Tokyo-ACE: Our Unique Tungsten Carbide Die and Punch
Early on, we recognized the potential of tungsten carbide, introducing EDM machines for die and punch material utilization. Over time, we refined our techniques in the micro hole, special shape, deep hole, and mirror (lapping) processing in tungsten carbide. The world's smallest die and punch for screws (hole diameter 0.24mm) is a testament to our expertise. Despite the low productivity of EDM, owing to pre-fabricated electrodes and forming via discharge energy, we have always aspired to develop new methodologies.
After much perseverance, in 2011, we mass-produced dies and punches by directly engraving on tungsten carbide
and finishing on machining centers, eliminating the need for lapping.

Tungsten Carbide Die and Punch for Hydrogen Fuel Cell Vehicle Separator
Features of Tokyo-ACE
1. Extended life (over 1.5 times longer than conventional methods)
2. Shorter delivery time (about 1/5 of conventional methods)
3. High precision (consistent μ accuracy)
4. Mass production (capable of handling orders of more than 100 pieces per lot)
Leveraging this technology, we are currently developing
tungsten carbide die and punch for forming separators used in hydrogen fuel cell vehicles. Achieving high precision over large areas with irregular shapes and mirror surfaces poses a significant challenge, but we are committed to achieving this within the next five years.
