Advanced High Speed Slitting Line Versatile For Various Coil Materials

Product Specification

Core Problem-Solving Capabilities:

The slitting line is purpose-built to overcome the pain points of conventional coil slitting and to close the performance gaps of older equipment. Its core capabilities are as follows:

1. Eliminating finished-product appearance defects: For the edge burrs, warping and surface scratches common in conventional processing, the line employs high-precision rotary knives together with a dedicated optimized process to deliver smooth, clean cut edges. No secondary edge trimming is required, defects are prevented at source, and scrap rates and rework costs in downstream stamping and forming operations are reduced.

2. Reducing excessive material loss: A precision control system, intelligent tension regulation and protective rollers work together to eliminate the tension instability and coil misalignment typical of conventional equipment, preventing coil telescoping, loose interlayers and cutting deviation. Material waste is minimized, delivering both cost reduction and more sustainable production.

3. Overcoming poor continuity and low efficiency: By replacing the frequent manual knife adjustment and manual maintenance of conventional equipment, the line greatly reduces operator intervention and shortens unplanned downtime. It resolves the low output and frequent interruptions typical of narrow-strip processing, keeping production continuous, stable and efficient.
 

Key Performance Advantages:

Built on a refined structural design and an intelligent control system, the line outperforms conventional equipment on every dimension. Its key advantages are as follows:

1. Ultra-high precision for high-accuracy applications: Width tolerance is controlled to ±0.05 mm with stable, accurate dimensions, fully meeting the demanding standards of EV battery housings, automotive structural parts and precision hardware. Downstream stamping, tube making and roll forming stay consistently on spec, and assembly deviation is eliminated.

2. Excellent efficiency for high-volume output: Maximum line speed reaches 120 m/min, and seamless dual-coil changeover lifts overall equipment efficiency by more than 30%, raising total capacity by 40% compared with conventional slitting lines. The line supports round-the-clock continuous operation and handles large-volume, short-lead-time orders efficiently.

3. Lower total cost with clear economic returns: Precision slitting reduces material loss by 3%–5%, cutting raw-material waste. The integrated PLC/HMI fully automatic control system sharply reduces dependence on manual labor, lowering labor cost by up to 40%. With no secondary edge trimming required, both process cost and time cost are further reduced.

4. Wide applicability and strong versatility: The line reliably processes cold-rolled steel coil, galvanized steel coil, aluminum strip and other metal coils up to 3 mm thick and 1250 mm wide, serving steel and aluminum service centers, automotive manufacturing, heavy household appliances, precision component manufacturing and many other industries.

Product Applications:

The slitting line performs high-precision slitting of thin, medium and heavy gauge steel strip, aluminum strip, cold-rolled and hot-rolled coil, stainless steel sheet, silicon steel sheet and other metal coils, cutting wide coils into narrow strips of standard specification and flawless quality. It supplies quality raw material for a wide range of industrial manufacturing processes and supports the refined, high-volume production needs of multiple industries. Core application scenarios are as follows:

1. Steel and aluminum service centers: Designed for steel and aluminum processors engaged in coil processing and finished-product distribution, the line standardizes the slitting of metal coils and produces premium narrow strip in a range of specifications. It enables service centers to broaden their product range, supply diversified raw materials to downstream manufacturers, and strengthen service capability and market competitiveness.

2. Automotive parts manufacturing: Focused on the production of new-energy EV battery housings, automotive structural parts and various automotive stampings. High-precision, defect-free slit strip fully meets the demanding dimensional and surface quality requirements of automotive parts, keeping subsequent stamping and forming operations consistently on spec. It is core equipment for automotive metal component production.

3. Tube and pipe manufacturing: Widely used in the production of welded steel tube, HVAC ducting and scaffolding tube. It supplies tube-making operations with standard narrow strip steel of accurate dimensions, flat edges and no burrs, safeguarding weld quality and finished-product accuracy and eliminating defects and rework caused by raw-material deviation.

4. Light industry and household appliance manufacturing: Serving the production of heavy household appliances, electrical cabinets and metal furniture, the line provides high-quality metal strip for appliance structural parts, metal stamping parts and profile roll forming. Its strong material adaptability ensures stable product quality and production efficiency.

5. General hardware and heavy-industry support: Applicable to sheet metal processing for port machinery, containers, agricultural vehicles and building materials, and to the large-scale production of precision hardware parts. Accurate dimensional control and excellent surface finish meet the high-precision raw-material requirements of heavy industry and hardware products.
