From Disposal Pressure to Fly Ash Bricks – Circular Economy at Xinfa
The Xinfa Group is one of the world’s largest aluminum producers. Through its subsidiary Chiping Xinyuan Green Building Materials Co., Ltd. (Xinfa), the group is consistently advancing industrial circular economy practices: by-products from energy generation and aluminum production—particularly FGD gypsum and fly ash—are processed into high-quality construction materials.
At the Chiping plant, ten LASCO KSE 1250 presses are currently in operation, manufactured by LASCO China with key components supplied from Coburg. The systems are designed for the economical production of fly ash bricks: each press stroke produces 36 small-format bricks, which are robotically destacked and then cured in autoclaves under steam pressure.
The KSE series stands out for its compact design, high cycle rates, and flexible adaptation to different raw material mixtures. For technical procurement specialists, a key advantage is that LASCO supplies the mechanical systems, electrical equipment, PLC control, safety technology, and robotics from a single source—resulting in optimized overall equipment effectiveness, short ramp-up times, and reduced integration risks.
Near-Net-Shape Preforming for Stable Aluminum Process Chains – SPR 3150 and RCW 560 at Zhongding
Anhui Zhongding Damping Technical Co., Ltd. is part of the internationally operating Zhongding Group and ranks among the leading automotive suppliers for advanced component solutions. At its Xuancheng site, aluminum components for vehicle body structures are manufactured in industrial-scale series production.
The production line integrates a LASCO SPR 3150 screw press and an RCW 560 radial forging / stretch rolling machine with a stretching robot as key processing units. The stretch rolling machine performs near-net-shape preforming of the blanks. This ensures targeted material distribution and reduces the degree of deformation required in the subsequent forging process. The result is optimized microstructures, reduced flash formation, and increased die service life.
For technical procurement specialists, the decisive factor is the coordinated combination of rolling and screw press technology—including a higher-level system control architecture. This creates a highly automated, stable process chain with clear responsibility for the entire system. Planning, integration, and process coordination from a single source reduce interface risks and ensure reproducible series production. Short changeover times, rapid roll replacement, and material savings of up to 30% further enhance overall cost efficiency.
Reproducible Quality for Aluminum Chassis Components – Screw Press Technology at Tuopu
Ningbo Tuopu Group Co., Ltd. is one of the leading Chinese automotive suppliers, specializing in chassis and NVH systems for international vehicle manufacturers. In the production of safety-critical aluminum components such as control arms, wishbones, and wheel carriers, dimensional accuracy, repeatability, and process stability are paramount.
At the Ningbo site, a LASCO SPR 2000 screw press is employed for this purpose. It performs precise forming of the aluminum components within a customer-integrated production line that includes furnaces, bending presses, and deburring presses. By delivering exact energy dosing in 1% increments and maintaining a stroke energy repeatability of ±1.5%, the press ensures consistently reproducible forming results.
The frequency-controlled drive allows short stroke times while reducing energy consumption through regenerative braking. For technical procurement specialists, the key advantages are high process stability, low grid load, and a robust design with optimized spindle geometry for long-lasting operation in series production.
