When traditional friction presses and ordinary hydraulic presses are used for clay brick molding, the core pain points are particularly prominent: Firstly, the pressure control accuracy is low, and it is difficult to flexibly adjust the pressing force according to the viscosity and moisture content of the clay raw materials. This often leads to defects such as loose centers, over-pressed corners, and surface cracks in the bricks, resulting in a low product qualification rate and inability to meet the demands of high-end refractory applications. Secondly, the force transmission is uneven, and the complex transmission structure leads to significant energy loss, making it impossible to achieve uniform pressure throughout the entire brick body. The density variation coefficient exceeds the standard, and during high-temperature service, stress concentration can cause peeling and damage, shortening the service life. Thirdly, parameter adjustment is cumbersome. For different specifications and mix ratios of clay bricks, manual adjustments of stroke and pressure parameters are required, resulting in low mold change efficiency and poor adaptability, making it difficult to balance mass production and customized production. Fourthly, energy consumption is high and maintenance is difficult. Traditional equipment has a lot of ineffective energy consumption, with energy consumption 50% higher than servo equipment, and the core components wear out quickly. Remote control is difficult, and it is not suitable for global production layouts. At the same time, the implementation of international rules such as the EU's carbon border adjustment mechanism, along with rising labor costs and stricter environmental requirements, further compels clay brick manufacturers to upgrade their molding equipment and seek efficient, precise, energy-saving, and intelligent molding solutions.

Compared to traditional molding equipment, the servo screw press, with its core advantages of digital precision pressure control, flexible adaptability, and energy efficiency, is the best choice for clay brick molding. It not only solves the problems of uneven pressure and high defect rates in traditional equipment but also compensates for the shortcomings of ordinary hydraulic presses, such as slow response and high energy consumption. It perfectly meets the core production requirements of clay bricks, including high density, precise dimensions, efficient mass production, and energy conservation, and is more in line with the green and intelligent transformation trends in the refractory industry, helping enterprises enhance their core competitiveness.

Relying on 45 years of experience in refractory molding equipment research and manufacturing, Zhengzhou Haloong has deeply integrated the third-generation permanent magnet synchronous servo direct drive technology with the semi-dry clay brick molding process to create a dedicated servo screw press for clay bricks. This press meets global high-end equipment standards and, based on the particle size requirements of clay raw materials, achieves the core goals of "precise pressure control, flexible adaptability, high efficiency and energy conservation, and stable reliability." It has become a "core weapon" for domestic and international clay brick manufacturers, comprehensively solving the industry's molding pain points and promoting the transformation of clay brick production towards high quality, high efficiency, and low energy consumption.

The press adopts a permanent magnet synchronous servo motor direct drive design, eliminating traditional clutches and gear transmission structures. The transmission chain is short and energy loss is low. It is equipped with an intelligent pressure control system that can precisely preset the pressing energy, speed, and frequency through digital programs, with energy repetition control accuracy of ≤±1%, far exceeding the industry average. It intelligently matches the three-stage molding process of "light pressure exhaust - medium pressure shaping - heavy pressure densification" based on the core requirements of clay bricks for "exhaust - densification - molding," thoroughly eliminating internal pores in the clay raw materials and effectively solving the layer cracking problem caused by traditional equipment pressing. At the same time, it precisely allocates the pressing force according to the viscosity and moisture content of the clay raw materials, ensuring uniform density from the center to the edge of the brick body, with a density variation coefficient controlled below 1.5% and a porosity reduced to below 15%. This significantly improves the compressive strength, high-temperature resistance, and wear resistance of the clay bricks, effectively eliminating defects such as cracking, corner chipping, and porosity, and maintaining a product qualification rate of over 99%, fully meeting international and domestic refractory industry standards and the quality requirements of high-temperature industrial applications.

It breaks through the structural bottom dead center limit of traditional equipment and adopts a step-by-step forging mode. It can flexibly adjust the slider stroke and pressing angle according to the requirements of different specifications and thicknesses of clay bricks, without worrying about overloading and jamming due to material size deviations or changes in raw material properties. Whether it is standard clay bricks, special-shaped clay bricks, large clay lining bricks, or customized clay brick products, precise molding can be achieved, ensuring that the dimensional accuracy error of the brick body is controlled within ±0.5mm, perfectly replicating the mold shape, and eliminating problems such as edge material deficiency and dimensional deviation. At the same time, the equipment can flexibly adapt to clay green bodies with different compression ratios without frequent adjustments to the equipment structure, significantly enhancing the molding adaptability and helping enterprises expand their clay brick product matrix to meet diverse market demands.

Relying on 45 years of refractory molding process experience from Haloong, the servo screw press can intelligently customize molding programs and press parameters based on the characteristics of clay raw materials from different origins and with different ratios. For different specifications of clay bricks, it is equipped with a rapid mold changing system, making mold replacement convenient and efficient. Combined with the built-in clay brick molding parameter database, it can automatically adjust the press energy, speed, and stroke according to product requirements, eliminating the need for frequent manual adjustments and significantly reducing production preparation time. The equipment has a high processing efficiency per stroke and can achieve continuous and stable mass production, with a production efficiency increase of over 30% compared to traditional friction presses. It can meet both small-batch customized production and large-scale mass production needs, helping enterprises quickly respond to domestic and international market orders and enhance market competitiveness.

Equipped with the intelligent production management system independently developed by Zhengzhou Haloong, it is equipped with standardized industrial communication interfaces, which can be seamlessly linked with upstream and downstream equipment such as automatic feeding systems, raw material ratio systems, green body inspection equipment, and intelligent storage systems, building an intelligent production line for the entire process of clay brick molding, achieving unmanned control from "raw material entry - ratio - pressing - inspection - storage". The system supports remote monitoring and parameter adjustment, facilitating domestic and foreign customers to manage production remotely, collecting molding data in real time, providing data support for process optimization, reducing errors caused by manual intervention, and being simple and easy to operate, even for non-professionals, significantly reducing labor costs and improving production stability, in line with the global trend of intelligent manufacturing.

Adopting the "on-demand start, sleep energy saving" intelligent mode, the servo motor only operates during the molding process, and stops and enters sleep mode during feeding, demolding, and mold changing processes, eliminating unnecessary power consumption. Compared to traditional friction presses, it saves over 55% of energy, with motor efficiency ≥ 95%, saving a significant amount of energy costs for enterprises each year. At the same time, the equipment intelligently optimizes the molding process, shortens the molding cycle, intelligently matches mold adaptation parameters, reduces green body rework losses, and increases the utilization rate of clay raw materials to over 99%, reducing raw material waste and carbon emissions, meeting global carbon reduction requirements and the green transformation needs of the refractory industry, helping enterprises achieve multiple goals of "energy conservation, cost reduction, and efficiency improvement", and enhancing their competitiveness in the international market.

Equipped with an intelligent diagnosis and early warning system, it can monitor the equipment operation status in real time, collecting and analyzing the wear, temperature, and operation parameters of core components such as screws, bearings, and motors, providing early warnings for potential faults, avoiding production losses caused by sudden equipment shutdowns, and reducing equipment failure rates by over 70%. It is equipped with a fully automatic forced lubrication system, intelligently matching the lubrication cycle and amount, reducing the friction loss of transmission components, doubling the service life of the equipment, and having a short transmission chain, simple structure, easy maintenance, and low later operation and maintenance costs, meeting the operation and maintenance needs of large-scale production of clay bricks in domestic and foreign enterprises, providing a solid guarantee for the continuous and stable production of clay bricks.
