cdocastBuy the Most advanced Tungsten Carbide For Types Of Mirror Metals Strip
Designed for rolling gold, silver, copper, platinum, and aluminum into flawless strips or sheets, the CDOCAST Tungsten Carbide Rolling Mill delivers ultra-thin outputs down to 0.1mm with bubble-free surfaces, burr-free edges, and exceptional thickness uniformity.
It mainly consists of the following parts:
1：Tungsten Carbide Rolls: Industrial-grade tungsten alloy for extreme wear resistance and prolonged service life.
2. Frame: Supports the rolls and withstands the rolling forces.
3. Drive System: Includes the motor, gearbox, and other components, driving the rolls.
4. Control System: Used to control the operation of the machine, such as working speed, forward and reverse rotation, tension, etc.
The price of the tungsten rolling mill is much higher than that of other materials. It is usually not used as the main equipment in production. Tungsten rolling machine is only needed when the surface quality requirements are very high. After rolling with Cr12 or DC53 rolling mill and then rolling with tungsten rolling mill for a few times, a very bright surface can be obtained.

Crafted from high-density tungsten carbide (hard alloy), our rollers boast an exceptional hardness of HRC 92-93—far surpassing conventional alloy steel rollers (HRC 60-65). With outstanding wear resistance, they deliver a 5-8x longer service life, making them ideal for high-precision, high-strength continuous rolling processes. Their unmatched stability ensures consistent performance without deformation over prolonged use.
Achieves pressing accuracy of ±0.01mm, producing sheets with uniform thickness, free of burrs or cracks. Perfect for processing ultra-thin materials like high-precision precious metal foils (gold, silver, platinum) and electronic foil components.
Our specialized polishing technology delivers a flawless surface with Ra≤0.05μm mirror finish, eliminating the need for additional polishing. Ready for immediate use in high-end decorative applications, electronic coating, and other demanding fields.
Featuring dynamic torque adjustment via excitation current (millisecond response), our magnetic particle clutch ensures precise control—ideal for frequent rolling force changes (e.g., varying materials/thicknesses). Its flexible coupling-like properties enhance process adaptability. During overloads (e.g., material jams), the clutch instantly slips to isolate excess torque, safeguarding machinery with rapid response and reliable protection.
Our servo-driven, high-precision coiling/uncoiling system, integrated with a magnetic particle clutch, enables fully automated continuous production. The closed-loop speed-tension control (±1% accuracy) dynamically adjusts rolling tension to prevent material stretching or breakage. Equipped with smart edge-guiding and constant-tension modules, it’s optimized for 0.01mm ultra-thin precious metal foils, ensuring wrinkle- and damage-free output. From uncoiling to rolling and recoiling, the entire process is completed in a single feed, boosting productivity by 40% while minimizing waste—the ultimate solution for premium foil processing.
A: The rollers of a tungsten carbide (hard alloy) rolling mill feature an extraordinary hardness of HRC 92-93, which far exceeds traditional alloy steel (HRC 60-65). Due to the high cost and complex processing of this material, it is not used as a primary reduction machine. Its core value lies in achieving a mirror-grade surface finish and exceptional consistency, making it the ultimate solution for high-end precious metal foil production and precision electronic foils.
A: Depending on the specific model (such as the CDO-RMC or RMM series), the equipment can process metals like gold, silver, and copper down to a thickness of 0.1mm or even 0.05mm.
A: CDOCAST utilizes specialized polishing technology to ensure the roller surface roughness reaches Ra ≤ 0.05µm. This means the rolled metal sheets achieve an extremely bright, reflective surface that requires no secondary polishing for high-end decoration, electronic plating, or other appearance-sensitive applications.
A: The magnetic particle clutch is a high-end configuration that serves two vital functions:
A: Yes. The CDOCAST system features an intelligent integrated winding system. By utilizing closed-loop control via servo drives and magnetic particle clutches, it synchronizes unwinding, rolling, and rewinding in a single process. This increases production efficiency by approximately 40% compared to manual operation while ensuring products remain damage-free and wrinkle-free.
A: Due to their superior hardness and wear resistance, tungsten carbide rollers typically last 5 to 8 times longer than standard steel rollers. They maintain excellent dimensional stability during continuous, high-intensity production and are highly resistant to deformation or wear indentations.
A: This machine is ideal for industries with rigorous requirements for metal thickness and surface flatness:
A: To extend the service life of expensive tungsten carbide rollers, we recommend:
A: We provide a 2-year warranty for this equipment. During the warranty period, we handle all after-sales services and provide necessary non-consumable spare parts free of charge.
A: The equipment utilizes a precision pressure molding design, allowing output tolerances to be controlled within ±0.003mm. This ensures superior thickness uniformity for all thin plates and foils.

The magnetic particle clutch is a high-end configuration that serves two vital functions:
1. Precision Tension Control: When rolling ultra-thin metal foils (around 0.01mm), it responds to torque changes in microseconds to prevent tearing or wrinkling.
2. Overload Protection: In the event of material jamming or abnormal pressure, the clutch slips immediately to protect the rollers and drive system from mechanical damage.
