In the fields of precious metal processing, precision electronics, and high-end jewelry manufacturing, high-precision, high stability, and high-efficiency rolling equipment are the key to improving product quality and production efficiency. As a benchmark brand in the field of precision metal processing equipment, Hasung has launched a 20 horsepower servo CNC precision tungsten steel rolling mill (model: HS-M8HPT), which has become the preferred equipment for achieving ultra-thin and mirror level metal sheet processing in the industry with imported tungsten steel rollers, full servo closed-loop control, and intelligent digital operation.

1、 Hardcore configuration: dual guarantee of high hardness and high precision

1. Imported tungsten steel roller shaft, creating ultimate durability
The core component of the tablet press, the rolling mill, directly determines the machining accuracy and service life. The Hasung 20 horsepower model is made of imported primary tungsten steel material, with a roller shaft hardness of up to 92-95HRC, far exceeding ordinary stainless steel and chromium molybdenum alloy, and possessing extremely strong wear resistance, compression resistance, and deformation resistance. After ultra precision mirror polishing processing, the roller surface smoothness can reach Ra0.02. The pressed gold, silver, platinum, K gold and various alloy sheets have a bright surface like a mirror, without scratches or indentations, and can be directly used for jewelry production, electronic lead and precision solder production without the need for secondary polishing.

2. 20 horsepower servo power, stable and powerful, more energy-efficient
The equipment is equipped with a 20 horsepower (about 15KW) high-power servo motor system, which has a more linear and stable power output and faster response speed compared to traditional hydraulic and ordinary electric motor types. The servo system can accurately regulate the roll gap and feed speed, avoiding pressure fluctuations and thickness deviations of traditional equipment, while achieving energy savings of 30% -50%. It has almost no energy consumption during standby and significantly reduces electricity costs for long-term use. The whole machine structure adopts thickened steel plate welding and precision bearing support, with a weight of about 950kg, stable operation without vibration, ensuring the stability of long-term continuous processing.
3. Core parameters: Breaking through the limit of ultra-thin processing
This rolling mill can process metal billets with a maximum feed thickness of 10mm. After single or multiple rolling processes, the thinnest can reach 0.03mm, and the thickness uniformity error is controlled within * * ± 0.005mm. The roller specifications are a diameter of 120mm x a width of 120mm * *, suitable for gold, silver, platinum, palladium, K gold, copper, brass and various precious metal alloys, meeting the diverse rolling needs of jewelry factories, electronics factories, new material laboratories and solder enterprises.

2、 Intelligent CNC: digital control, efficient and worry free

1. PLC+touch screen, full process intelligent control
The equipment is equipped with an industrial grade PLC control system and a 7-inch high-definition touch screen. The operation interface is simple and intuitive, and parameters such as tablet thickness, feed speed, and cycle times can be set with one click. Support parameter storage and calling, products of the same specification can directly access historical programs to avoid duplicate debugging; Real time display of operating status, roller temperature, cumulative processing length and other data, automatic alarm and shutdown for abnormal situations, significantly reducing operational errors and material loss.

2. Closed loop servo control with zero precision deviation
Adopting a fully closed-loop control architecture consisting of dual servo motors and high-precision displacement sensors, the roller shaft clearance is monitored in real-time and automatically fine tuned, completely solving the pain points of “large manual adjustment errors and long-term accuracy drift” in traditional tablet presses. Whether it is pressing 0.1mm gold foil or 0.03mm ultra-thin silver foil, the thickness consistency is always stable, the finished product qualification rate is close to 100%, and the material loss tends to be zero.
3. Automatic thickness measurement and correction, suitable for large-scale production
High end models can be equipped with online laser thickness gauges and automatic correction winding systems. During the rolling process, the thickness of the sheet is detected in real time and feedback is adjusted. At the same time, the winding offset is automatically corrected to ensure that the roll material is neat, without misalignment or wrinkles. Combined with automatic feeding and continuous rolling functions, a single equipment can achieve 24-hour uninterrupted mass production, with processing efficiency 3-5 times higher than manual and semi-automatic equipment, suitable for the large-scale production needs of medium and large factories.

3、 Application scenario: Covering the entire precious metal industry chain

1. High end jewelry manufacturing
In the processing of gold, platinum, and K-gold jewelry, this equipment can roll metal ingots into precision sheets of 0.05-1mm, which are used to make ring faces, pendants, hollow jewelry, and filigree substrates. The mirror level surface directly enhances the luster and texture of the jewelry, reduces polishing time, and minimizes precious metal loss.
2. Precision Electronics and Solder Industry
For electronic leads, connectors, shielding covers, and pre formed solder pads, we can stably produce ultra-thin copper, silver, and gold alloy sheets with a thickness of 0.03-0.5mm, uniform thickness, neat edges, and no burrs, meeting the strict requirements of electronic components for dimensional accuracy and conductivity.
3. Research and development of new materials and laboratory
Suitable for universities, research institutions, and new material enterprises, it is used for rolling experiments of rare metals such as platinum, palladium, rhodium, and new alloys, accurately controlling thickness and forming quality, and providing reliable sample preparation equipment for new material research and development.

4、 Quality and Service: Hasung’s Brand Confidence
As a national high-tech enterprise specializing in precision precious metal equipment for more than ten years, Hasung’s 20 horsepower servo tungsten steel rolling mill follows the EU CE and ISO9001 quality standards from design, material selection to production and testing. The core components are imported brands, and the entire machine comes with a one-year warranty and lifetime maintenance. We also provide on-site installation, debugging, operation training, and process guidance services. The equipment is produced at the Shenzhen headquarters and is available in stock. It supports customized roller width, rolling thickness, automatic winding and unwinding, and other special configurations to meet the personalized production needs of different customers.

Conclusion
Under the trend of precision metal processing transforming towards intelligence, high precision, and high efficiency, the Hasung 20 horsepower servo CNC precision tungsten steel rolling mill has redefined the performance standards of precious metal rolling equipment with three core advantages: high hardness tungsten steel roller shaft, full servo closed-loop control, and digital intelligent operation. It is not only a “processing tool” to improve product quality and reduce production costs, but also a core equipment for enterprises to achieve industrial upgrading and seize the high-end market, injecting strong intelligent manufacturing power into the precious metal processing, electronic manufacturing, and high-end jewelry industries.
