High-Precision Heavy Tungsten Alloy Components from China Suppliers - Ideal for Printing Equipment 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
The 97% heavy tungsten alloy (WCo) maintains long-term sharpness and integrity of groove edges, providing uniform ink transfer and preventing defects like uneven ink thickness or blurred edges.
Its high density allows dense tungsten alloy plates to efficiently dissipate vibration energy created during the printing process, substantially minimizing vibration-induced artifacts and improving accuracy.
WNiCr Doctor Blades offer a service lifespan three times longer than standard steel blades due to their superior wear resistance (0.02 mm³/nm) and hardness (280–320 HV).
We support high-precision machining tolerances down to ±0.005 mm for rollers and blades, along with optional PTFE, DLC, or ceramic coatings to optimize ink release.
Tungsten components provide high thermal stability, unmatched durability, and extreme precision necessary for intricate anti-counterfeiting security features on banknotes.
