Leveraging servo closed-loop tension control and modular design, our products adhere to international standards such as ISO, ASTM, and EN, achieving core technical breakthroughs in precision and efficiency. To date, we have served over 500 clients across global markets, with proven performance in new energy battery casing production, automotive stamping, and home appliance manufacturing.

Technical Definition

A slitting line is an automated metal processing equipment that cuts wide metal coils into narrow strips with precise dimensions, based on servo control and precision mechanical principles. It enables consistent, high-volume processing to meet feedstock requirements for stamping, roll-forming, and tube-making. As a core solution in metal processing, it is essential for efficient production in automotive, new energy, and home appliance industries.

Main Categories

To meet diverse industry needs, our slitting lines include multiple series with customizable options:
1. Standard Slitting Lines: High-precision series suitable for thin-to-medium gauge coils (0.1-3mm), featuring ±0.05mm width tolerance and burr-free edges.
2. Double Recoiler Slitting Lines: Designed for continuous high-volume production, reducing downtime from coil changeovers by 80%.
3. Slitting & Cut-to-Length Compound Lines: Integrated solution combining slitting and cross-cutting functions, saving 40% factory space.

Design Philosophy

Our products follow the core design philosophy of high precision, high stability, low material loss, and easy maintenance. We adhere to full-life cycle reliability standards to ensure stable performance in harsh industrial environments, delivering cost-effective solutions for clients.

Technical Principles

The core working principle of our slitting lines is based on servo closed-loop tension control, which ensures consistent material tension throughout the processing chain. The full workflow includes:
1. Coil Loading & Uncoiling: Automated coil feeding with edge alignment to prevent material deviation.
2. Tension Control & Slitting: Servo-driven systems maintain stable tension, paired with precision rotary knives to achieve clean, burr-free cuts.
3. Recoiling: Uniform winding of narrow strips to avoid telescoping or surface scratches.

Core Architecture & Innovative Design

Our slitting lines feature two key innovative modules:
1. Servo Tension Control Module: Closed-loop real-time adjustment eliminates material stretching or deviation, ensuring consistent strip quality for both thin and thick materials.
2. Quick-Change Knife Module: Standardized interfaces reduce tool changeover time from 2 hours to 30 minutes, adapting to small-batch, multi-variety production.

Technical Parameters & Standards

All parameters are tested in accordance with ISO and ASTM standards, with clear test conditions and tolerance controls. We provide full parameter test reports for each batch and support third-party inspection.

Technical Advantages & Differentiation

Our slitting lines have three verifiable core advantages validated by global client applications:
1. High Precision & Low Material Waste: Supported by servo closed-loop tension control and precision rotary knives, we achieve ±0.05mm width tolerance and reduce raw material scrap by 3-5%, lowering production costs for clients.
2. Energy Efficiency & Cost Savings: Using permanent magnet synchronous motors and energy recovery systems, our lines consume 15% less energy than industry averages, saving over $42,000 annually per line.
3. Quick Changeover for Flexible Production: Modular design cuts changeover time from 2 hours to 30 minutes, boosting overall production efficiency by 40% for multi-variety orders.

Technical FAQ

Q: Do you offer OEM and ODM services?
A: Yes, we provide both OEM and ODM services to meet specific customer requirements.
Q: How many workers are needed to operate the machine?
A: Only 1-2 workers are required due to fully automated PLC/HMI control.
