High Precision Heavy Tungsten Alloy Components for Printing Equipment - China Suppliers and Factory
Description
In intaglio printing processes for printing equipment, the WCo intaglio roller made from 97% heavy tungsten alloy maintains long-term sharpness and integrity of groove edges on the roller surface, ensuring precise and uniform ink transfer while effectively suppressing defects such as uneven ink layer thickness and blurred pattern edges, thereby significantly enhancing print quality. In 3D printing applications, dense printing plates fabricated from 97% heavy tungsten alloy leverage their high density to efficiently dissipate vibration energy generated during printing, substantially reducing vibration-induced artifacts and further improving printing accuracy and product stability.

Frequently Asked Questions (FAQ)
The 97% heavy tungsten alloy (WCo) maintains long-term sharpness and integrity along groove edges, ensuring uniform ink transfer and preventing defects like uneven thickness or blurred edges.
Tungsten alloy offers a significantly higher density (17–19 g/cm³ vs. 7.9 g/cm³ for steel and 2.7 g/cm³ for aluminum), an exceptionally low wear rate (0.02 mm³/nm), and minimal thermal expansion (4.5 μm/m°C), providing superior durability and dimensional stability.
Common grades include WNiFe (95% W) for cylindrical balancers, WCu (90% W) for inkjet nozzle plates, WNiFe (97% W) for dampers, WNiCr for doctor blades, and WCo for gravure rollers.
In 3D printing, dense plates made from 97% heavy tungsten alloy leverage their high density to rapidly dissipate vibration energy, reducing vibration artifacts and improving printing accuracy.
We provide precision machining with tolerances down to ±0.005 mm, coating options including PTFE, DLC, and ceramic coatings for enhanced ink release, available in rods, plates, or CNC-machined parts.
Yes, tungsten alloy is non-magnetic, making it suitable for MRI-safe environments, and its precision characteristics make it critical for banknote and anti-counterfeiting printing machinery.
