In high-precision manufacturing, managing operational solid waste while maintaining a pristine workshop environment is a common logistical hurdle. This case study evaluates the five-year performance of AUPWIT’s custom-engineered Fully Automatic Metal Baling System at KOSO Control Engineering (Wuxi) Co., Ltd. Implemented in 2021, the system features a synchronized automatic hoist, an extra-height hopper, and the Y81PTZ metal baler integrated with advanced fluid drainage. Over half a decade of high-intensity operation, the solution has completely automated the client's iron scrap handling, achieved total liquid-solid separation, and sustained optimal operational uptime with zero major component failures.
KOSO Control Engineering (Wuxi) Co., Ltd. is a recognized leader in the production of industrial control valves and automated instrumentation systems. Serving heavy sectors such as oil and gas, petrochemicals, and power generation, their manufacturing processes require ultra-precise machining and large-scale metal cutting. These operations generate a massive, continuous volume of raw iron chips and metal turnings on a daily basis. To maintain production velocity, the company requires a highly streamlined, safe, and sustainable method to handle its industrial solid waste.
AUPWIT engineered a closed-loop, customized Fully Automatic Metal Baling System tailored specifically to the structural constraints and high-capacity needs of the Wuxi plant. The turnkey line comprises three interconnected technical innovations:
urnkey line comprises three interconnected technical innovations:
System Component | Technical Specifications & Customization | Operational Impact |
Heavy-Duty Automatic Hoist | Automated mechanical lifting cradle matched to the shop floor collection carts. | Eliminates manual material handling, facilitating direct vertical up-feeding. |
Custom-Heightened Hopper | Engineered with extended vertical containment walls to accommodate high-volume batch dumps. | Guarantees zero material overflow or dust scatter during the tipping cycle. |
Y81PTZ Metal Baler & Fluid Extraction | High-pressure hydraulic compaction system integrated with an oil collection tank and a heavy-duty drainage pump. | Compresses chips into ultra-dense blocks while actively pumping out and reclaiming cutting fluids. |
During the process, factory carts are secured into the automatic hoist, lifted, and tipped into the hopper. As the Y81PTZ baler exerts extreme hydraulic pressure onto the chips, the cutting fluid is squeezed out, routed immediately into the built-in collection tank, and discharged via the drainage pump. The processed iron is then ejected as high-density, uniform 250×250 mm bales.
In June 2026, AUPWIT's technical service team performed a comprehensive 5-year routine inspection at the Wuxi facility. The data collected confirms that the line has transformed the factory's scrap processing efficiency:
Manual handling was completely removed from the scrap workflow, allowing the factory to reallocate dedicated waste labor to core production tasks.
The integrated oil collection tank and pump solved the longstanding problem of fluid dripping, ensuring strict alignment with local environmental and green factory regulations.
The uniform 250×250 mm bales maximized storage space and significantly reduced truck transport frequencies, lowering secondary logistics costs.
After 5 years of processing highly abrasive iron chips, the high-tensile wear plates and hydraulic seals remain within factory tolerances, proving the superior build quality of AUPWIT machinery.
