Yoder Supplies Tooling for Electrical Transformer Housings

Yoder recently supplied two roll tooling sets to a capital equipment manufacturer for the production of pole mounted electrical transformer housings.  The tooling is designed for forming a band into a ring, which is used for closure of the assembled transformer.

Yoder’s roll forming tooling is purposefully designed and manufactured to meet a range of custom and high production, industrial applications.  For more information, contact yoder@formtekgroup.com call (216) 292-4460 or visit www.yodermfg.com.

Yoder Supplies 5” Mill for Mechanical & Structural Tubing

Yoder recently supplied a tube mill for mechanical and structural tubing.  The mill has a capacity of 5” OD, ¼” maximum wall thickness, and can re-shape up to 4” square or 2” x 6” rectangle.  The system includes Yoder’s latest design of weld box, which is a 5-roll arrangement for larger products and 4-rolls for smaller diameters.  Additionally, the system includes the WH-350-RS reshaping stands, which can reshape up to 4” (101.6 mm) square, rectangles up to 6” (152.4) wide and as small as 2” (50.8 mm) in the horizontal and vertical axes, for materials up to 0.250”  (6.35 mm) thickness.  The reshaping stand has been designed so it may be retrofitted on any mill that makes up to 5” (127 mm) round, and can directly replace existing Yoder W-35 and WH-350 Sizing Stands. 

In addition to the mill mechanicals, Yoder provided the general engineering for the project, providing foundations and arrangement for the coil handling, welding and cutoff equipment for planning of the customer’s Greenfield site.

5 Ideas to Consider in Roll Forming - by Jeff Carson

What is roll forming and why do I need it? 

Fundamentally roll forming is defined as a continuous, high-volume, fabricating process in which a desired shape is formed from a flat strip of metal by passing it through a series of matching pairs of contoured rolls.  Only bending occurs in the roll process and does not change the thickness of the metal except for a slight thinning at a bend radius.  Roller forming is a continuous process that is extremely economical and efficient particularly when the job requires shaping sections into extended lengths at high volume.  The advantages of roll forming are widely recognized and include:

• Processing over 500 feet per minute
• Consistently formed material
• Maintaining extremely finite tolerance range

In today's competitive marketplace, it is necessary to have robust equipment that consistently delivers quality product in a consistent pattern.  In addition to sheet leveling units, other forms of roll forming technology include parts leveling, cut to length lines, slitting, embossing, stitching as well as custom-designed process lines.

What are the types of roll materials?

Rolls are generally made from tool steel, the grade being dependent on the expected production and finish of the piece.  For routine applications where a smooth finish strip is to be formed or when shapes are formed from hot rolled, unpickled steel, a High Chrome-High Carbon tool steel (AISI D-2) with about 1.5% carbon and 12% chrome is suggested.  Tool steel has exceptional wear performance and for the average run of light gauge cold formed sections can be expected to roll several million feet or more before........ click the photo to read more on the B&K Framing Blog 

Fenstration Roll Forming - Yoder

Several fenestration components are most efficiently reduced by roll forming, particularly, hollow metal door frames, vinyl window stiffeners, trim, balancers, screen frame, and muntin bars.  Whether structural steel or pre-painted aluminum cladding, Yoder designs tooling and machinery specifically for the unique demands of the fenestration industry, supplying complete systems for component distributors or OEMs looking to produce their components for just in time manufacturing.  In order to leverage existing installations, individual machines, tooling and system upgrades are also available to improve productivity and roll forming throughout, such as the addition of inline notching for muntins of the lockbar for door and window latche
