Shaped Wire Drawing Dies
Single Crystal Diamond Dies
・Compared with the rolling method, the surface gloss is higher, and the wire with high dimensional accuracy can be achieved. ・Can support various shapes from squares to track shapes with high accuracy. ・Squares can be drawn with minimum a side of 0.08 mm. ・Material type is polycrystalline diamond. ■Features ・Copper wires such as flat cables, Connector pins for OA equipment, jewelry such as necklaces, Alternators for automobiles, Copper wires for voice coil motors, micro motors, Actuators, etc. ■Applications Supports a Wide Variety of Shapes, from Squares to Track Shapes A.L.M.T. Corp. know-how is utilized for diamond used in the manufacture of various wires, such as motor windings in the automotive industry, connector pins and flat cables used in general electrical equipment, and chains of necklaces (for jewelry).
Applicable to Ultra-fine Wires with a Minimum Diameter from 0.008 mm to about 1.0 mm Artificial single crystal diamond, which is the ultimate material that has high hardness, high bending strength, and high thermal conductivity. Furthermore, the crystal orientation and shape that can reflect the highest performance into the die design. Diamond dies have basic high precision and long life. It is particularly suitable for wire drawing, and can be applied to fine wires as small as diameter 0.008 mm to 1.0 mm. *For 0.010 mm or smaller diameter, please contact us. ・Effective for ultra fine wires that are required to have high surface quality and straightness. ■Features
・Wire Materials ■Applications
Soft Wire Materials: Hard Wire Materials:
Copper wire, Aluminum wire, Brass wire, Gold wire, etc. Stainless steel wire, Brass plates steel wire, Galvanized steel wire, Copper plated steel wire, Tungsten wire, Molybdenum wire Ultra-precision diameter dies, like bonding wires, which require surface quality and straightness, require dies with smooth and highly symmetrical cross-sectional shapes.

Lineup that is Applicable for Stable Quality Dies and Large Diameter Dies. Polycrystalline diamond (PCD) material that is made by powdered brazing alloy together with a binder alloy at ultra-high pressure. The lineup supports large diameters, it reflects performance in a larger diameter size range than single crystal diamond. The applicable range is from 0.04 mm to 29.0 mm. ・Applicable to sizes larger than those drawn by single crystal diamond dies. ・Usable in a wide range of applications since drawing is not affected by the crystal orientation. ■Features
