Understanding the Function of a Cut-to-Length Blanking Line

A Cut-to-Length (CTL) Blanking Line plays a critical role in metal fabrication processes. It is engineered to transform metal coils into flat sheets or blanks by unwinding, leveling, and then cutting them into specified lengths. These sheets are then ready for downstream applications or assembly. Such systems are particularly valuable for operations that demand accurate dimensions and consistent quality in metal components.

These systems are indispensable in industries such as automotive, construction, and home appliances, where both high precision and cost-efficiency are key to ensuring product integrity and production speed.

Highlights of Our CTL Blanking Line Solutions

Our Light and Medium Gauge Cut-to-Length Blanking Lines are packed with cutting-edge technology that delivers superior performance. Key benefits include:

  • Maintains precise length tolerances across different material widths and thicknesses

  • Processes delicate surfaces without damage

  • High-speed operation with stable material handling

  • Fully automated threading from coil to stacker

  • Integrated stacking system for uniform, square output stacks

  • Real-time diagnostics and controls for consistent accuracy and productivity

  • Optional modules such as coil handling, part sorting, protective film application, and palletizing can be integrated to boost throughput

Light Gauge Cut-to-Length Blanking Line

Technical Scope
This line is optimized for thin materials ranging from 0.008" (0.2 mm) to 0.135" (3.5 mm) in thickness. Suitable substrates include Pre-Painted Steel, Galvanized Steel, Hot-Rolled Steel, Aluminum, and other non-ferrous metals.

It is capable of processing at speeds up to 400 FPM (122 m/min) and can hold tight dimensional tolerances of ±0.005" (0.127 mm).

Application Fields
These lines are commonly used in sectors that depend on lightweight yet precise components. Automotive manufacturers utilize them for body panels, while the construction industry benefits from their use in siding and roofing. They're also widely applied in appliance manufacturing for producing parts for devices like refrigerators and ovens.

Trusted by Leading Companies

  • Greenpoint Metal
    Expanded from coil-only services to offer both coils and sheets, thanks to the line’s multi-blanking function, which enables slitting and cutting in one operation. This capability has improved productivity and helped lower costs.

  • Conklin Metal Industries
    This company, a key player in HVAC and steel supply, leverages the system's safety features (light curtains, sensors, and gates) to protect workers while maintaining high output. The built-in recoiler and continuous stacker support small coil production without compromising efficiency.

  • Wieland Metal Services
    Serving the roofing and signage sectors, Wieland has greatly enhanced its operations by adopting the multi-blanking solution. Previously separate slitting and blanking processes are now unified into one streamlined workflow, improving stacking accuracy and reducing manual handling.

Medium Gauge Cut-to-Length Blanking Line

Red Bud Industries broke new ground by developing the first Medium Gauge CTL Blanking Line that offers the same close-tolerance precision previously only available for lighter materials. This advancement has had a significant impact across the metal processing industry.

Specifications
This system is built for materials between 0.015" (0.38 mm) and 0.375" (9.5 mm) in thickness. It handles a wide range of metals including Hot-Rolled, Cold-Rolled, Pickled & Oiled, Galvanized, Pre-Painted, and High-Strength Steels. It is also compatible with Stainless Steel, Aluminum, Brass, Copper, and various specialty alloys.

Its ability to process thicker material makes it an ideal choice for robust applications that require strength and durability.

Industries Served
These lines are essential in the production of heavy-duty components. Automotive firms use them for structural parts and chassis systems. Construction companies depend on them for manufacturing load-bearing components like beams and frames. They are also vital in the machinery and industrial equipment sectors, where strength and precision go hand in hand.
