Product Description
I. Introduction
The automatic coil slitting machine is designed to slit wide coils into narrower strips with precise cutting tolerance and stable tension control. It operates through a continuous process of uncoiling → leveling → slitting → recoiling, making it ideal for mass production in various industries.
This machine supports a wide range of materials such as:
Cold-rolled steel
Hot-rolled steel
Stainless steel
Galvanized steel
Aluminum coil
Color-coated / pre-painted steel
Silicon electrical steel
Industries Served:
Automotive, HVAC, Household Appliance, Construction, Packaging, Container Manufacturing, Electrical Components.
Ⅱ.Features
Fully Automatic Operation: Integrated design for uncoiling, slitting, and recoiling in one continuous process.
Mitsubishi PLC System: High-speed data processing and reliable global control.
Servo Motor Drive: For precise positioning, efficient feeding, and low tolerance cutting.
High Accuracy: Tolerance up to ±0.1 mm, slitting speed up to 120 m/min.
Optional CPC/EPC Control: Ensures better coil edge positioning during decoiling and recoiling.
Rugged Mechanical Frame: Built with high-strength steel structure, high rigidity for stable and durable performance.
Low Scrap and High Output: Optimized blade shafts and advanced scrap recoilers reduce waste and increase productivity.
Whether you process narrow or wide coils, the automatic coil slitting machine from Lihao offers dependable performance with minimal operator intervention.
