High-Precision Heavy Tungsten Alloy Components for Printing Equipment - China Suppliers & 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.
The Advantages of Alloy Types
Eliminates vibration in rotary printers.
Prevents clogging and extends service life.
Reduces blurring in high-speed digital printers.
Have a lifespan three times longer than steel blades.
Maintains sharp grooves for precise ink transfer.
Compared to Technological Advantages of Steel/Aluminum
- 50% heavier than steel – enhances momentum control of moving components.
- Hardness (280–320 HV) – resistant to scratches from pigments or abrasives.
- Non-magnetic – essential for MRI-safe printing facilities.
