Print E-mail

MINO has been awarded by Ningbo Powerway Alloy Plate & Strip Co., Ltd one more Contract for the supply of a new Four High Roughing/Intermediate Cold Rolling Mill for Copper and Copper Alloys.

Founded in 1987, Powerway is a Chinese high-tech enterprise group which has by now become world leader in producing, researching and developing non ferrous alloys.

Ningbo Powerway Alloy Plate & Strip Co., Ltd. is a company fully committed in the development of new materials and in the innovation of the technology of  production of non ferrous  alloys. Powerway Group products include environmental protection alloys, alloyed electrodes, new alloys, brazing materials, copper-nickel alloys, bronze, brass, high precision pure copper alloys for electronic applications.

The continuous effort of Powerway Group in technological innovation, that has allowed the group to develop several invention patents, has led the Group to win various prestigious titles such as "National Enterprise Technical Center", "National Key High-tech Enterprise", one of "First 93 National Innovative Enterprise", "Excellent Private Enterprises in Science and Technology in China", "Model Enterprise for Informatization".

Powerway group has presided over and participated in the establishment of national standards and industry standards on copper alloys.


The award of this latest Contract comes after the previous successful cooperation between MINO and Ningbo Powerway for the installation of the MINO Six High Finishing Mill.


The new Cold Mill, which shall be installed in the same workshop where the previous MINO Six High Finishing Mill is located, shall produce copper and copper alloys strips starting from maximum incoming thickness of 18 mm down to the minimum thickness of 0.4 mm, on a maximum width of 460 mm.


The Cold Mill has the outstanding characteristic of being capable of producing either coils to be sent to the MINO Six High Mill for finishing rolling, either coils to be delivered to the customers as final products.

To achieve this, the new Cold Mill will be equipped with work roll lubrication & cooling system by pure oil, suitable to ensure that the strip will have the surface quality as required from final products.

Moreover, the new Cold Mill will be provided with the latest generation of MINO Process Control’s AVANTItm TCS system (AGC/AFC controls) that will allow to achieve the tightest thickness and flatness performances requested by today’s market.

The TCS system of the mill will be complete with MINO’s mathematical models for pass schedule calculation and optimization, developed by MINO in the previous similar rolling mills.


This new Cold Mill, which shall be designed following the latest MINO’s design concept in the field of copper alloys rolling, represents a new outstanding example of the pinnacle achieved by MINO’s copper Mills in terms of quality & performance. The repeat orders from a same Customer are a tangible evidence of that.



The key data of the mill are:

Type of Mill Four-High Reversing Finishing Mill
Rolled material
Copper and Copper Alloys
Max. entry strip width 460 mm
Max. entry strip thickness 18 mm
Min.  exit design strip thickness 0.4 mm

New Foil Finishing Mill for LAMINAZIONE SOTTILE
Print E-mail

Founded in 1923, Laminazione Sottile is the leading Italian Company in the field of rolled aluminium products. With more than 105.000 tons produced in 2017, they cover a wide range of product applications such as packaging, HVAC-R, automotive, cookware and building.

Laminazione Sottile has the ability to supply aluminium coils, sheet, foil and circles in different alloys and widths with gauges ranging from 6 mm down to 6 microns.


On February 2015 the Final Acceptance Certificate of their new MINO Cold Mill was signed by Laminazione Sottile, marking the successful completion of Phase 1 of its long term  investment programme in rolling assets.

In 2017 and following the successful completion of Phase 1, MINO received the green light to proceed with the implementation of Phase 2 of the programme, consisting of the design, manufacture and supply of a new Foil Finishing Mill.

The new Foil Mill will be installed in the same Caserta plant and will further add rolling capacity to a long list of equipment supplied by MINO over a 40 year time span:

-      one Cold Mill supplied in 1980 and recently refurbished by MINO with new process

       control system;

-      one Foil Roughing Mill supplied in 1983;

-      one Hot Mill supplied in 1998;

-      the latest Cold Mill commissioned in 2015.


MINO is particularly proud of the long term partnership with Laminazione Sottile, the extent of which now covers nearly 40 years. This relationship is evident by the contract awards given to MINO in hot, cold and foil rolling mills which show a deep level of cooperation and technical trust between the two Companies.


The new Foil Finishing Mill has high-speed rolling potential and will display the latest MINO mill stand design concepts. On-line strip doubling and a number of electro/mechanical solutions allow for tension control at reels over an extremely broad range of material specifications. Complimenting the mill stand are automatic spool transfer devices, a side trimmer and state-of-the-art sensors & instruments.

As with all new MINO mills, the ‘Avanti’ advanced AGC/AFC system controls flatness and thickness of rolled strip. AC motors & drives provide low maintenance, flexible control of speed and torque.


The Mill’s design and automation system is developed in compliance with the Industry 4.0 guidelines, such as advanced process control and monitoring systems, friendly man/machine interface, interactions between different machines, intelligent maintenance system, remote diagnostics.
