Roll Forming Machines

THE ROLL FORMING PROCESS

The coiled or sheet, flat strip metal to be formed is passed through a series of paired rolls, to progressively form the desired profile. Pre-notching, post-notching, embossing, cutting to length and several other engineered features can be incorporated into the automatic operation of the roll forming process.

RLW Series - Light Duty

The RLW Forming Machines serve the area of light metal forming. Versatile in operation and readily adjustable for a wide range of light moldings and window air spacers. They require very little floor space and may be easily relocated for production planning. These machines find a wide application in the production of small tubing, trim moldings, weather-strip sections and many other high volume light items. These Roll Forming Machines can also be built with variations to accommodate special operations to fit metal forming needs within the machine's working range.

MLW Series - Medium Light Duty

The MLW Model Roll forming Machines are used for forming medium light sections that are slightly wider and slightly deeper than the light series. These machines may be applied efficiently and economically for low as well as high production jobs. The close horizontal distance of roll spindles permits easier forming of pre-notched stock into complicated of irregular shapes. Common products produced on MLW Series roll formers include roll-up garage doors and vinyl window stiffeners.

HMW Series - Medium Duty

The HMW Model Roll Forming Machines cover the range of medium moldings. These machines have more depth range than the MLW series. Light gauge, wide stock may be easily formed without loss of shaft rigidity. Horizontal roll space is well proportioned for smooth and accurate flow of metal from one pass to another to produce an accurate form even on deep irregular shapes. Like all other models, they are built as a complete "ready to run" package, ruggedly constructed for long life and minimum maintenance. Refrigerator shelving supports, store fixture components are a couple common applications for the HMW Series roll forming machines.

MW Series - Medium Heavy Duty

These models are the most popular used in industry today. They are built to withstand the continuous high production pressure placed on roll formed product manufacturers. Highly flexible and readily adaptable, with a great variety of working accessories, the MW machines with heavy-duty shafts are capable of handling medium and light materials up to 30" wide. These machines together with other models are adapted easily into automation lines performing work in one continuous operation. Truck-trailer components, garage door tracks, seat tracks and other automotive components are most common in the MW Series.

HW Series - Heavy Duty

These models serve the area of heavier metal forming. Ample power and rigidity are built into these machines to perform heavier rolling operations at maximum speeds. Like other models, these machines, with slight modifications, may be joined in tandem with one another to produce heavy intricate rolled sections. The clean functional design makes these models an ideal choice in automated lines producing structural rolled sections such as door frames, channel, angles, precision drawer slides and many other high production heavy items.

XHW Series - Extra Heavy Duty

The XHW Series is the largest standard size Roll Forming Machine made by Tishken for practical production rolling. Designed to meet the demand for handling wide and deep heavy sections, these machines are constructed with ample room for a great variety of working accessories. In addition, these models give all the advantages found in the lighter models. Guard rails, automotive bumpers, and a variety of other products using high strength steels and exotic metals.

APPLICATION

Whether it is decorative appliance trim, store fixture shelving, roll-up garage doors, drop ceiling grid, HVAC louvers, or highway guard rails, there is a roll former for the application.
