  • These Plate Bending/Rolling Machines have four rolls and liner guidance for the side rolls.
  • The top roll remains fixed, the bottom roll moves vertically, and the two side rolls move in a liner guide way to form the shell.
  • The top and bottom rolls are power-driven by planetary gearboxes with hydraulic motors (in some capacities).
  • Thin plates need closely spaced rolls to avoid driving slippage.
  • The location of the bottom roll directly below the top roll ensures a very good grip on such jobs.
  • Due to the high productivity of low-thickness shells, the four roll machines prove to be an attractive investment for mass production of pipes and shells.
  • Over and above the cones, other non-circular shapes like oil tankers & elliptical shells can be made.
  • This type of roll configuration also facilitates CNC operation.
  • 20-30% higher investment for the same thickness capacity and span compared to a similar three roll machine.
Monotech Four Roll Plate Rolling Machines deliver par performance and flexibility. They are also extremely durable and accurate, and are therefore ideal for medium-to-heavy duty rolling.

GAIN THE MONOTECH ADVANTAGE!

A major factor is position accuracy in the press brake. You want an accurate machine to make the best bends possible with your materials. When you buy a Monotech press brake instead of an conventional one you can guarantee the position accuracy is dialed in. Enjoy saving money and time with an accurate press brake.

You’ve heard the phrase, “time is money.” Your new Monotech press brake will perform better than conventional one, hands down. Our machine is more accurate, more efficient, and built (typically) on newer technology. Get a Monotech press brake to take advantage of increase performance and take 10% off your cycle times.

Monotech press brakes tend to be more energy efficient than Conventional ones. They’re built on better technology and require less pull to operate. This means you’re spending less on utilities to run the machine, which means you can reinvest those Rupees to get another press brake or even tighten up other areas of your production line.

Reduced noise improves your work environment, as well as allows for clear communication to occur. Get rid of noise issues and get a Monotech press brake.

The biggest benefit to Monotech press brake machines is the cost-effectiveness of their operation. Our machines lasts longer and are much more durable than a conventional Press Brake. Our machines require less maintenance & negligible breakdown calls, thereby making it much more cost effective by offering you hassle free smooth operations!

Enjoy the peace of mind that you are in good hands.

Build Quality & Benefits

Sturdy Steel Structure

Ever since the inception, Monotech Engineers Pvt. Ltd. have put the best foot forward and created the best industrial machinery/equipment according to the client’s demands. Being an ISO 9001:2015 certified company, we believe in making just and fair deals with our clients. For that we have the best team one could ask for. With the support of an experienced and dedicated team of professionals, we have been able to serve reputable government and private agencies such as BHEL, BEML, Defense Unit, and NTPC.

Rolls

The rolls are the most important elements of our machines. Monotech designs the rolls with optimal diameter and uses forged carbon steel rolls that are machined by high precision CNC lathes. Our rolls have a special spline-based design that is extremely efficient in connecting the rolls with the planetary gear system. This diminishes points of roll failure compared to welded connections provided by other manufacturers.

Hydraulic Gear System

Additional energy saving is ensured in our Four Roll machines by a hydraulic system which can work at less than full capacity when jobs less than maximum thickness are rolled.

Monotech Engineers Pvt. Ltd used in our machines is efficient and eliminates energy wastage associated with heavy-transmission systems and yet achieves the goal of speed reduction by increasing the stages in gears and pinions.

Operational Benefits

Pre-Pinching (Pre-Bending)

Edge bending can be done before or after shell rolling depending on operator skill and choice. Thin plates can be rolled and edge-bent in a single pass.

Edge Bending

The cone bending process with the K series is simple. The bottom rolls need to be inclined to achieve cone bending geometry. This is controlled and monitored by electronic microprocessor (on some models).

Our control system also ensures easy and accurate return to parallel setting after cone bending resulting into precision on repetitive jobs.

High Productivity

Our state-of-the-art technology in forming cylinders
and cones delivers unmatched precision and efficiency.
Designed for ease of installation,
these systems are extremely user-friendly and convenient to service, ensuring minimal downtime. With a straightforward interface

Versatility

Other than cylinders and cones, other non-circular shapes like oil tankers and elliptical shells can be made using a PLC version.

Economy

Due to the exceptional build quality, failure-resistant linear guideway design, high operational precision and a wide range of jobs that can accurately rolled, the F series machines prove to be the most attractive investment for any type of industry, regular production or a job shop.
