Finishing Line for Leather Manufacturing | Integrated Processing Component

Product Specifications

Technical details and manufacturing context for Finishing Line

Definition

The Finishing Line is the concluding component of the Integrated Leather Processing System, responsible for applying various surface treatments, coatings, and finishing processes to leather materials to achieve desired aesthetic qualities, functional properties, and market-ready characteristics. It integrates sequential stations for spraying, coating, drying, buffing, embossing, and polishing, using automated or semi-automated equipment to ensure consistent quality and surface properties. The line processes leather materials with finishing chemicals and coating materials, and its performance is characterized by parameters such as production capacity (500–2000 m²/h), line speed (5–30 m/min), working width (1.2–3.2 m), coating thickness (0.01–0.5 mm), coating uniformity (±5%), drying temperature (40–120 °C), heating power (50–200 kW), air flow rate (5000–20000 m³/h), operating pressure (0.4–0.8 MPa), electrical supply (380 V AC ±10%, three-phase, 50/60 Hz), installed power (80–300 kW), noise level (≤75 dB(A)), machine weight (10–40 t), and footprint (20×5–40×8 m). These values are reference ranges that must be confirmed for the actual model and application. The Finishing Line is a component of a larger system, and its selection requires consideration of leather type, desired finish, production volume, and integration with upstream and downstream processes. Verification questions should address specific model capabilities, compatibility with existing equipment, and compliance with applicable standards. Maintenance signals include variations in coating uniformity, drying efficiency, or noise levels, indicating potential wear or misalignment. Failure boundaries are defined by the operational limits of the equipment, such as maximum temperature, speed, and pressure, beyond which product quality or safety may be compromised. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

Leather materials move through sequential stations where different finishing treatments are applied, including spraying, coating, drying, buffing, embossing, and polishing, using automated or semi-automated equipment to ensure consistent quality and surface properties. The line operates with adjustable parameters such as line speed, coating thickness, and drying temperature, which are controlled to achieve the desired finish. The process involves the application of finishing chemicals and coating materials, followed by drying and mechanical treatments to enhance the leather's appearance and functionality.

Components / BOM

Spraying Station
Applies finishing chemicals and coatings evenly across leather surface

Material: Stainless steel
Drying Tunnel
Cures and dries applied finishes using controlled heat and airflow

Material: Insulated steel
Buffing Unit
Polishes and smooths leather surface to desired finish

Material: Abrasive materials, steel
Embossing Roller

Frequently Asked Questions

What is the Finishing Line used for?

The Finishing Line is the final processing stage in leather manufacturing, applying surface treatments, coatings, and finishing processes to achieve desired aesthetic and functional properties.

What are the typical production capacity ranges?

The production capacity is typically in the range of 500–2000 m²/h, but this depends on line width and coating type. Confirm the exact value for your specific model.

What parameters affect coating uniformity?

Coating uniformity is affected by line speed, coating thickness, and roller settings. Higher speeds can reduce uniformity, so adjustments must be made carefully.

How should I verify the specifications for my application?

Always verify model-specific values, such as working width, drying temperature, and electrical supply, with the legal manufacturer or supplier to ensure compatibility with your leather type and production requirements.
