Our premium Roll Mold series is engineered for high-performance industrial applications, utilizing a rigorous multi-stage forging and heat-treatment process to ensure unmatched structural integrity. By strictly adhering to a precise forging ratio of 3:2-2.5, we optimize the material's internal grain structure, delivering a product that excels in high-stress machining environments.
Designed for longevity and precision, these rolls undergo a comprehensive thermal cycle and precision quenching process to achieve an ideal hardness range of 58° to 62° HRC. Every unit is meticulously inspected by professional quality controllers, ensuring that the final output provides maximum wear resistance and dimensional stability for your metal forming and machining operations.

Frequently Asked Questions
Our process utilizes a specific forging ratio of 3:2-2.5 and repeated forging cycles (2-4 times) combined with a 72-hour annealing stage to ensure superior material organization and durability.
We implement a strict quenching process between 930-980°C and follow it with low-temperature tempering. Every single workpiece is then verified via hardness detection to meet the 58°-62° standard.
Yes, our rough processing and finishing stages are specifically designed to follow customer drawings, including precise inner hole dimensions and custom logo placement.
Annealing at 780°C to 830°C for 72 hours relieves internal stresses from the forging process, which prevents cracking and enhances the overall stability of the tool during operation.
Our finishing stage includes comprehensive planar finishing, inner hole finishing, and well-finishing to ensure a smooth, high-precision surface for all industrial interfaces.
A forging ratio of 3:2-2.5 ensures that the raw material is sufficiently deformed to break down the cast structure and refine the grain, which directly results in higher impact strength and wear resistance.
