1. Straight hole dies can be manufactured according specified
drawings |
2. ± 0.005 mm tolerances |
3. Possibility of tooling design |
1) High hardness, good thermal conductivity and low friction coefficient
2) Low cost, used in some wire processing processes with high loss and high hardness
3) Uniform wear and tear during use
4) Tungsten carbide core can withstand 2800 ° C high temperature

Blank inspection-All PCD, MONO/SSCD, ND, and TC dies produced by
Coolervie are checked under Microscope by 100X material
magnification, so that dies with any impurities, cracks and spots
could be easily detected and rejected. If these cracks or spots
exist, the abnormal internal-stress will cause die cracking during
die manufacturing or wire drawing process.
◆Outer casing production:Only high-quality casing can be a good
carrier for high-quality dies. Coolervie uses excellent
stainless-steel materials, and completes three sets of process:
cutting casing, creating setting area, and creating blank area in
the cutting process of fully automatic machine tools, ensuring the
perfect concentricity without moving the die shell.
◆ Reinforcement-Diamond should be firmly protected by metal matrix,
which is formed by the sintered metal powder, reinforcing
diamond to endure wire impact without breaking and to extend wire
die life. Coolervie's auto-sintering process is accomplished by
the combination of an infrared sensor, auto-feeder and a high
frequency sintering machine.
◆ Coning-An automatic turning machine completes front and back
cones and two parallel flats.
◆ Cylindrical grinding-In order to ensure the precise dimension and
roundness of casing, every casing should be ground by
centerless grinding machine to tightly control the tolerance within
5 microns.
◆ Laser die profile drilling-The precision and consistency of our
dies profiling has been improved dramatically since we purchased
a state-of-art laser die drilling unit. A double side profile
drilling is achieved by this most up-to-date laser drilling
machines.
