Automobile Inner and Outer Board Press Blanking Lines are specialized production systems designed for cutting large-format sheets from coils with the precision and surface quality required by the automotive industry. These lines are capable of processing cold rolled steel (CRS), hot rolled steel (HRS), and aluminum, covering the full range of materials used for both interior and exterior automotive body panels. With a press capacity of up to 800 tons and a maximum sheet size of 5,200 × 2,750 mm, they deliver the force and accuracy needed for producing flat blanks ready for stamping into final automotive components.

Key Features & Advantages

Versatile Material Processing: Handles CRS, HRS, and aluminum across thicknesses from 0.2 mm to 3 mm, meeting both lightweight and structural automotive needs.

High-Capacity Press System: Up to 800-ton pressing force ensures precise, burr-free cutting even for large-format and thick materials.

Large Sheet Dimensions: Accommodates widths from 300 mm to 2,080 mm and lengths from 300 mm to 6,000 mm, suitable for a wide range of vehicle panel sizes.

High-Speed Operation: Capable of up to 65 strokes per minute (SPM) for maximum throughput.

Dual Stacking Systems: Magnetic and vacuum stacking systems ensure precise sheet alignment and safe handling of both ferrous and non-ferrous materials.

Surface Protection: Non-contact vacuum systems and carefully controlled sheet transfer prevent scratches and edge damage, ensuring Class A surface quality.

Automation Integration: Automatic sheet length setting, coil feeding, and stacking minimize operator intervention and downtime.

Heavy-Duty Construction: Built for continuous, high-volume production with long service life and low maintenance requirements.

Product Instructions

The production process begins with coil loading and feeding into a precision leveling unit to ensure flatness and eliminate internal stresses. The leveled sheet is then accurately positioned in the press area, where the blanking die cuts the material into the required shape. Depending on the material, magnetic or vacuum stacking systems are used to transport and stack the finished blanks without surface damage. The automation system controls coil handling, length adjustment, press synchronization, and stacking, all based on pre-set production data. This minimizes manual adjustments and maximizes operational efficiency. Safety features, including guarding and automated sheet handling, ensure a safe working environment even at high speeds.
