MD-1350 Mid-Range Slitting Workhorse: Complete Guide to 4mm-12mm Coil Processing

What makes MD-1350 ideal for 4mm-12mm coil processing?

The MD-1350 is engineered to excel in processing coils with thicknesses from 4mm up to 12mm, striking a precise balance between power, precision, and operational efficiency that addresses the demands of medium-thickness coil production in 2025. Equipped with a robust 318.5KW power system and a versatile working width range spanning 300mm to 1300mm, it caters to diverse manufacturing needs without requiring major facility modifications. What distinguishes the MD-1350 is its adaptive speed control capable of ranging from 1 to 250 meters per minute, intelligently modulating based on material thickness to maintain consistent quality. This machine delivers clean, burr-free cuts even at the upper thickness limits, supported by advanced servo-controlled slitting heads and multi-zone tension systems that preserve edge integrity and dimensional accuracy within tight tolerances.

Successful deployments in automotive, HVAC, and general fabrication sectors exemplify the MD-1350’s reliability, where its capacity to handle coil weights from 10 to 35 tons aligns perfectly with typical mid-range production volumes. Real-world case studies highlight the machine’s ability to maintain edge quality and reduce material stress, features critical in high-precision applications. This mid-tier powerhouse closes the gap between entry-level models that falter under material stress and costly heavy-duty lines, offering optimal return on investment by combining high throughput with lower capital expenditure. Ultimately, the MD-1350 delivers a technical synergy of strength and finesse, making it the benchmark solution for medium-thickness coil processing in advanced manufacturing environments.

Understanding Medium-Thickness Metal Processing Challenges

Processing metal coils between 4mm and 12mm thickness presents distinct metallurgical and mechanical challenges that differentiate this range from both thin-gauge and heavy-plate applications. Material behavior in this intermediate zone requires specialized consideration of work hardening characteristics and cutting dynamics.

Material Stress Distribution in Medium-Thickness Cutting

At the 4mm-12mm range, metal exhibits complex stress patterns during the slitting process. The shear zone depth becomes proportionally significant relative to material thickness, creating edge quality challenges that don’t typically manifest in thinner materials. Work hardening effects increase cutting force requirements non-linearly with thickness—thicker materials within this range may require substantially more cutting force than simple thickness ratios would suggest.

The MD-1350’s 318.5KW power specification provides sufficient cutting force for clean processing through the entire thickness range while maintaining consistent edge quality. This power level ensures reliable operation across various material grades, from mild steel to stainless steel and aluminum alloys commonly processed in this thickness range.

Precision Control Requirements

Medium-thickness coil processing demands exceptional tension management to prevent material wandering and edge defects. Unlike thin-gauge applications where material flexibility assists in process control, or heavy-plate processing where material rigidity provides inherent stability, the 4mm-12mm range requires active compensation throughout the cutting cycle.

The MD-1350’s variable-speed drive system (1-250m/min) allows operators to optimize cutting parameters for different material grades within the thickness spectrum. This speed flexibility proves essential when processing work-hardened stainless steel compared to annealed mild steel, where optimal cutting speeds may vary significantly despite similar thickness values.
