Cut-to-length and Slitting Lines | PLC Controlled Automatic Tool Changer for Coil Service Centers

 

Oscillating Type Rotary Shear Cut-to-Length Line | Blanking for Continuous Galvanizing Line | Automatic Blade Changing Slitting Line

As a leading manufacturer of light- to heavy-gauge cut-to-length and slitting lines since 1979, we have been providing custom design and manufacturing services for coil processing lines and equipment. Our clientele includes rolling mills, coil service centers and engineering & design companies in the steel, automotive, shipbuilding and appliance industries.

 

We have implemented over 700 cut-to-length lines and 2,000 refurbishing projects for slitting lines around the globe. Our clients include POSCO, Hyundai HYSCO, Hitachi, Nippon Steel, Vulcan Steel and Jindal Steel.

 

Our robotic slitter line reduces downtime and increases safety during blade setting processes with a robotic arm that automatically adjusts the number of blades and the gap between the blades, based on the available blades and the size of the width strip’s gap. This automated cut-to-length line is popular amongst automotive coil processing centers.

 

Our oscillating-type rotary shear cut-to-length line is another innovation that offers continuous sheet metal cutting in various angles at high speeds. This oscillating shear line and our multi-blanking line are ruggedized to be suitable for bath type deep galvanizing lines.

Coil Processing Line | Coil Slitting Machine | Mini Coil Slitting Lines

With decades of design and manufacturing experience, we offer fully automated coil processing lines in various configurations and sizes, from mini-slitting lines to heavy gauge slitting lines. For seamless integration into a wide range of clients’ line layouts and coil types, we manufacture both standalone and custom continuous slitting machines for heavy gauge coils.

 

Our high-speed line equipment produces up to 300 meters per minute for steel and aluminum materials. Our equipment processes a maximum coil thickness of 17 mm and a maximum coil width of 1,830 mm.

 

The unique advantage of our design is that it reduces downtime and increase operator safety during tool assembly and changes.  Our Hydraulic Expansion Slitter (HES) uses hydraulically powered arbors to hold the blades, which removes the need for spacers during tool assembly. By simplifying the tool assembly process, our HES also reduces downtime and improves usability during tool assembly. Our turret type re-coiler is also designed and manufactured with two drums for increased usability, as it and quicker blade change between jobs.

 

Our heavy gauge slitting lines are installed at major mills worldwide, including mills operated by Nippon Steel Corporation, HYSCO America, Union Steel Mexico, POSCO, MMK-Atakaş, Vulcan Steel, Attieh Steel.

Heavy Gauge Cut-to-Length Line | Heavy Gauge Steel Coil Levelers | Rotary Flying Shear | Oscillating Shear

Clients using our cut-to-length line select our oscillating type rotary shears for the innovative technology that offers superior usability and operator safety. As our flagship product, the oscillating rotary shear, coupled with our steel coil leveler, allows clients to continuously cut trapezoidal shapes while the coil strip runs at speeds up to 100 m/min and thicknesses of up to 12.7 mm.

 

Our coil levelers can be configured with interchangeable cassettes in addition to the conventional 6-HI and 4-HI configurations for each client’s specific needs according to material, production capacity and quality requirements. Our versatile designs afford our clients the flexibility to choose the exact configuration for their needs, as well as the option to adjust the configuration to their changing needs. Our interchangeable cassette is yet another example of our design principle of minimizing downtime and increasing usability, particularly during roller replacement.

 

Our jumbo leveler in combination with heavy gauge cut-to-length lines can level coils with thicknesses of up to 25.4mm, and is suited for applications such as shipbuilding manufacturing sites.

 

Rolled Steel Materials for Coil Service Centers

Our light and heavy gauge cut-to-length lines are designed and manufactured to process various materials, including hot and cold pressed rolled steel, galvanized steel, and ferrous and non-ferrous materials:

  • High Strength Steel

Blanking & Slitting Line Business Case

Blanking & Slitting Line Business Case (PDF)

POSCO acquired flat steel processing equipment from LPR for its MPPC plant in Mexico. POSCO-MPPC first started its operation in 2006 and primarily targeted he automotive industry. With the double-digit growth in the automotive second, the expansion of their processing capabilities lead to construction for additional locations within Mexico to be established.

 

LPR Global has a long-term partnership with Korean Steel Giant POSCO.  With LPR being the steel coil processing equipment manufacturer of choice to develop their coil processing equipment lines across the globe. LPR was the preferred partner for POSCO to supply equipment to meet their growing demand  in Mexico due to the reliability of our equipment and meeting stringent quality requirements of the automotive industry.

Even though the business historically had been targeting automotive industry, but they expanded their sales efforts within construction and machinery segments as well. Target clientele of POSCO were to include household appliance manufacturers, automotive industry, construction industry, steel furniture manufacturers, oil tanker barrel manufacturers, and tubes manufacturers.

 

This required a set robust lines to cater to a wide variety of materials and dimensions of coils. Blanking, Slitting and Shear lines were designed to process mainly galvanized steel sheets, electrical steel, cold rolled steel, hot rolled steel, pre-coated/ painted steel, electro galvanized and stainless-steel coils.
