Case Study: Supplying a 1600mm High-Speed Slitting Line to a European Client

This case study shows how Kinbenz designed, manufactured, and commissioned a 1600mm High-Speed Slitting Line for a major European coil processing factory. By sharing project details, key challanges, and measurable results, we aim to boost your confidence in choosing Kinbenz.

FQA:

1. What is a 1600mm High Speed Slitting Line used for?

A 1600mm slitting line processes wide metal coils - up to 1.6 meters in width - into narrower strips at high speeds (maximum up to 220m/min). It is ideal for coil processing factory that supply strips to automotive, construction, and appliance manufacturers.

2. How do you choose a slitting line for European standards?

European clients typically require CE certification, precise +/- 0.05mm tolerance, robust tension control, and high automation. Make sure the manufacturer has experience exporting to Europe and can handle customized safety features.

3. How long does it take to install a 1600mm Slitting Line?

Installation and commissioning usually take 2-4 weeks on-site by our experienced enginner, depending on local conditions, civil work, and required training.  Pre-shipment FAT (Factory Acceptance Testing) in China usually lasts 1-2 weeks.

Project Review:

• Client Location: Türkiye 
• Machine: Double-head 1600mm High Speed Slitting Line
• Material: Stainless Steel, Thickness 0.2-2.0mm
• Speed: Up to 220m/min
• Number of slits: 0.2-2.0mm ≤ 20pcs
• Completion: Commissioning in Q1 2025

Key Client Requirements:

1. Wide Coil Capability

• Able to process 1600mm master coils 
• Target strip widths: 100mm-800mm

2. High Production Speed

• Maximum 220m/min running speed to meet European throughput  standrads

3. Precision & Edge Quality

• ±0.05mm slit width tolerance
• Burr free, smooth edges, safety interlocks, and emergency stops

4. Automation & Safety

• CE-compiant guards, safety interlocks, and emergency stops

5. Servicing & Space Part Support

• Spare part kit shipped with the line (blades, spacers, belts)
• Remote diagnostic access and 12-month warranty

Main Challange:

1. Maintaining ±0.05mm Tolerance at High Speed

Iuuse: High speeds amplify any misalignment or vibration, causing width variation or burr formation

Solution: 

• Precision CNC-machined slitter arbor using forged 42CrMo steel for hardness and wear resistance
• Servo-controlled tension modules with feedback from load cells to stabilize strip loop.

2. CE certification and European Safety Standards

Issue: EU regulations reuire forced-ventilation enclosures, light curtains, and redundant safety interlocks.

Solution: 

• Kinbenz's design team integrated CE-approved guarding and SIEMENS PLC with safety I/O modules.
• Local electrical schematics were customized to match EU wiring standards

Solution Highlights:

1. Customized Machine Design

Frame & Decking: Reinforced welded steel frame, annealed and machined flat to ±0.02 mm.

Decoiler: Hydraulic uncoiler with flange spreader for 1600 mm coils

Blade Material: Forged 42CrMo circular blades, Ø 85 mm hole, quenched & tempered, hardness 60–63 HRC.

2. On-Site Installation & Commisioning

Timeline: One experienced Kinbenz engineer deployed to Türkiye for 15 working days

Activities: 

• Civil foundation levelling (± 0.5 mm flatness tolerance)
• Mechanical alignment (laser‐levelled) of frame to pillars
• Electrical wiring according to local code (VDE)
• Dry run checks, slitting of local coils, operator training

Results & Clients Feedback

• Production Capacity Increase: From 120 t/day to 180 t/day (+ 50%)
• Quality Improvement: Width tolerance consistently within ± 0.05 mm.
• Downtime Reduction

Conclusion & Call-to-Action:

Supplying a 1600 mm high-speed slitting line to our European client showcases Kinbenz’s ability to deliver customized, reliable, and high-performance solutions. By focusing on precision machining, robust tension control, and CE-compliant safety, we helped our client achieve higher throughput, better quality, and lower operating costs.
