Steel plate processing equipment (such as Slitter line)

To build a good slitter line, it is necessary to have an original design according to various criteria.

For example, characteristic and shape of the material, the size of plant and personnel, and appropriate driving speed.

Therefore, our company discuss in detail of our customers' needs and detail prior to the design specification. Made to order by a consistent system from design to manufacturing, we deliver to our customers the best line.

In the field of IC frame and mold which precision is demanded, we are good at micron technology accuracy by its own control. We also have been very reliable by clearing the high-standard terms of usability efficiency and cost performance.
"I want to launch a slitter line of products with such characteristics""Is it possible to make the capacity of the line higher? " Such a variety request offer comes to our company.

As we specialized in designing custom-made line, because of the comprehensive strength born from the abundant know-how and technical strength developed over many years.

Identify problems, analysis and consider addition from the broad view, demonstrate all the available technology we keep the attitude to pursue through the user benefits. Not only satisfy the demands, we also have an ability to suggest own proposal.
