In the current automotive manufacturing landscape, where agility, material innovation and throughput matter more than ever, the blanking line from SUMIKURA Co., Ltd delivers precisely the capabilities required for tomorrow’s production demands.
https://sumikura.jp/blanking-lines-2.html
Material & Application Versatility
As OEMs shift toward lighter-weight constructions and multi-material architectures, the ability to handle both steel (CRS/HRS) and aluminum becomes a strategic asset. Aluminum blanking is gaining traction in the automotive sector, driven by the need to reduce vehicle mass to improve efficiency and EV-range. SUMIKURA’s blanking line supports aluminum, cold-rolled and hot-rolled steel, with sheet thicknesses between 0.5 mm and 3.0 mm. This gives manufacturers the flexibility to blank body-in-white panels, closures or structural components across a variety of substrates and platforms.

Large Sheet Formats & High Throughput
Modern vehicle designs often call for larger blank sizes thanks to increasingly integrated body structures and multi-platform architectures. SUMIKURA’s machine accommodates sheet sizes up to 5,200 × 2,750 mm under its press capacity (max 800 t), and supports widths from 300 to 2,080 mm and lengths from 300 to 4,300 mm. With production speeds up to 65 SPM, this ensures that large-format blanks can be delivered at the pace required for high-volume automotive stamping and body shops.

Lean Handling & Automated Stacking
In the drive toward lean manufacturing and just-in-time blank delivery, reducing manual handling, scrap and downtime has become essential. According to industry overviews, blanking lines deliver high processing speed, precision and material-utilisation benefits. SUMIKURA’s integration of both magnetic and vacuum stacking systems further supports clean handling of blanks, rapid transfer to downstream presses or forming lines, and consistent output quality — enabling suppliers to feed stamping operations with minimal interruption.

Strategic Fit for Lightweighting & Mixed-Material Platforms
With automotive manufacturers adopting mixed-material architectures (aluminum + steel) and prioritising weight reduction for fuel economy or EV range, blanking equipment must respond to this complexity. Lightweighting is not simply about swapping materials, but ensuring the entire process chain (blanking → forming → joining) supports the end-goals of performance and cost-efficiency. SUMIKURA’s system handles the width, length and material-type flexibility required for mixed-material part families, making it well-suited to serve multi-platform strategies and supplier-tier consolidation.
