Market Background
In Serbia and the Balkan region, metal recycling is shifting toward more standardized pre-processing. Scrap yards expanding capacity often face unstable cutting rhythm with mixed materials, more jamming/waiting time, and difficult feeding of bulky scrap—directly impacting loading efficiency and hourly throughput. That is why buyers prefer measurable RFQ criteria (t/h, cuts/min, opening sizes, size-based cutting references, hydraulic pressure and cooling method) instead of “tonnage” alone.

Customer & Application Scenario
The customer is a Serbia-based scrap yard operator. The machine is installed at the scrap pre-processing shearing station to cut common ferrous materials (square/angle/round steel, I-beam, plate, and channel) under mixed-material conditions. The priority was a controllable rhythm, less manual intervention, and a standardized workflow for safer shift operation.

Our Solution
We supplied one 400-ton container scrap shear (Model Q43W-4000A3), configured strictly to the technical parameters, with a 40-day lead time. The solution was designed around throughput, rhythm, feeding adaptability, and verifiable duty boundaries: 4–6 t/h capacity and 3–4 cuts/min for production planning; a 3200×2400 mm feeding opening and 1400 mm blade length for better tolerance of bulky/mixed feeding; 25.0 MPa system pressure plus an air-cooling oil system to define continuous-duty conditions; and a power/hydraulic setup based on 37 kW motors and 160 ml/r pumps to support stable flow and cycle execution.

Key Technical Specifications 

Customer Feedback (Validation)
During installation and trial runs, the customer checked the size-based cutting references, cutting rhythm, and feeding smoothness. Because expectations were aligned through parameter-based clauses, acceptance was straightforward and communication was efficient.

Summary
This Serbia project shows a practical RFQ approach: translate “throughput and rhythm” into measurable criteria—4–6 t/h, 3–4 cuts/min, 3200×2400 mm feeding opening, 1400 mm blade length, 25.0 MPa system pressure, and air-cooling oil management—creating verifiable boundaries for mixed scrap pre-processing.

Customer Feedback (Outcome)
The customer confirmed the machine meets the scrap yard’s pre-processing needs for throughput and workflow standardization. Mixed-material feeding became easier to organize, and the cutting rhythm was more controllable in daily operation.
