At Kinbenz, we don't just assemble machines - we engineer reliability from the ground up. With over 30 years of experience in coil processing equipment, our slitting liens are trusted by manufacturers across automotive, construction, home appliance, and metal service industries worldwide.
But what does it really take to build a high-quality slitting line?
In this article, we take you behind the scenes of our metal coil slitting line production process - from raw steel to final commissioning - and show you why Kinbenz machines stand the test of time.

- Independent CNC Machining Workshop
- In-house Welding & Assembly Workshop
- Precision Engineering Team with 30+ Years of Know-how
- Global OEM & Custom Design Services
What Makes a High-Quality Slitting Line?
High-performance slitting lines offer:
- Precise coil slitting with ±0.5mm width tolerance
- Fast operation speeds (up to 220m/min)
- Smooth recoiling with no edge burrs
- Durable parts that last 10+years
- Easy operation & Minimal maintenance
How We Build a Kinbenz Slitting Line
Design & Engineering
Each line begins with an in-depth discussion with the customer:
- What materials? (SS,CR,GI,AI,Cu)
- What coil width/ thickness range?
Our engineers create a layout of the full production line using CAD.
PAA: What are the design considerations for slitting lines?
Answer: Material hardness, thickness range, slit width tolerance, automation level, coil weight, and desired speed.
Precision CNC Component Machining
Unlike many other suppliers, Kinbenz owns our CNC machining center, allowing us to produce:
- Slitting arbors and bearing housings
- Blade holders and precision spacers
- Leveling rollers and blade shafts
This ensures:
- Perfect fit between components
- Long lifespan with minimal vibration
- Full control over tolerance and finish
Heavy-Duty Frame Welding & Stress Relief
Our workshop welds all machine bases and structural parts. Then, we apply:
- Annealing heat treatment to reduce stress
- CNC surface milling to ensure perfect flatness
This process guarantees machine stability, especially under high-speed and heavy-coil load conditions.
Assembly & Blade Setup
Our experienced technicians install:
- High-speed slitter heads
- Tension control systems
- Recoiler with hydraulic arms
- Pneumatic or servo blade adjustment modules
Each line undergoes dry run testing before final delivery.
Trial Run with Customer Material
Before Shipping, we invite customers to:
- Visit our factory for live trial run
- Inspect slit coil width, burr height, and edge quality
This ensures "what you see is what you get"
