Weld Fixture Specialists Offers New Products to Manufacturers.


Rentapen Inc. Listens to Customers, Makes Alterations To Product Line And Creates Four New RAPid Blocks™

On June 21, 2013 Rentapen Inc. added four New RAPid Blocks™ to their collection of six RAPid Blocks™.  Rentapen Inc., located in Waukesha, WI, first developed RAPid Tooling Components™ in the year 2002.

The RAPid Tooling Component™ product line was inspired by Rentapen’s customers’ need for dramatic reductions in the overall design, set-up, and operation costs of welding and other tooling fixtures. Rapid Tooling Components™ (RTC) reduce the design cost of the fixture by eliminating the need to design, detail and check similar parts over and over again.

 “We found that it was costing our customer $100 to design, check, cut, and create a block.  We realized we could do it cheaper.  With RAPid Tooling Components™, it now costs that customer about $37 for the same block and they don’t have to design and check it each time,” said Susan Straley, President and Owner of Rentapen.  “Our product line saves time in the design and build of product part holding fixtures.”

The new RAPid Blocks™ are RB11, RB12, RB16, & RB19 and can be downloaded for free on Rentapen’s website.  RAPid Blocks™ are standard yet versatile parts that are used with locating pins, rest pads, jig feet, and other parts in a weld fixture.

The new blocks are improvements to a now discontinued blocks; which was limited to only a 3/8 screw size.  These improvements allow the customer to use any screw size (1/2, 3/8, ¼, & 5/16) needed to complete the design of the weld fixture.

The RB11 & RB16 is designed with two drill and counter-bored holes used to screw the block to the plate and one press fit hole to hold a dowel.  In the front of the RB11 there is one round screw hole used for front and back shim adjustability.  The RB16 is designed the exact same way but with one large difference.  Instead of a round hole, it is designed with a slot for optimum side to side adjustability of up to ¼”.

The RB12 & RB19 is designed with three drill and counter-bored holes used to screw the block to the plate and two press fit holes to hold a dowels.

The RB12 and RB19 are designed to be longer, in order to locate other parts and to keep them square on the weld fixture.  Similar, to the design of the RB11, the RB12 has round screw holes used for shim adjustability in 3 directions of up to 1/8”.

RB12 has two oversized holes; located at each end of the block. To solidly hole the subassembly against the RB12 but still is able to allow adjustments in the side to side and up and down directions.  Rentapen created a weld fixture design lesson with slide show to explain better with images.

The RB19 is designed similar to the RB12 but it is designed with a two slots for additional side to side adjustability.

To provide their customers with the best price, Rentapen makes each RAPid Block™ when it is ordered. Keeping finished goods inventory costs low and passing on the savings to Rentapen’s customers.

When a machine design engineer, is designing a weld fixture they can go to Rentapen’s website and download 3D models of any RAPid Tooling Components™ they want.  In fact, the designer actually creates the parts according to their specific application right on the site, without having to search in a paper catalog to find the right product number.  The site, Weld Fixture Components asks the right questions and with the answers creates the 3D parts and generates the part number.

The user can choose to download 3D models of blocks, plates, clamp risers and shims.  Rentapen’s RAPid Tooling Components™ are mostly used in weld fixtures, but have also been used in other machine tooling, like assembly fixtures.

We wanted to make it easier for machine tooling designers to find the right component for their needs.  We are excited to have the new blocks on the website and we are looking forward to our official launch of these new products in the next few weeks.

Recently, three new companies have taken advantage of Rentapen’s web app to download 3D models of RAPid Blocks™ and RAPid Shims™ into their fixture designs. First was a manufacturer of Original Equipment Manufacturing (OEM) out of Georgia.  Second, was a mechanical design company and the last company is a manufacturer of welding and cutting systems, which includes robotic arc welding and cutting.

Machine Design Engineers and CAD Drafters from the U.S., Mexico, and Canada are able to go to Rentapen’s website and perform six quick steps to order the 3D models to place in their weld fixtures.

We encourage Tooling Engineers to save the 3D models to their libraries so that they can use them again and again. Before we created this line, companies were spending close to $100 on a similar block.  Now they buy it from us for under $40.  These components save an Machine Design Engineer’s time and their company’s money.

Milwaukee, WI Weld Fixture Specialists Enhances Business Relationship With a Georgia Manufacturer.


The Engineering Manager at Rentapen Inc., a growing weld-fixture design and build company, flew to Georgia to gain knowledge to better assist customer in 2013.

On June 18, 2013 Blake Peterson, Engineering Manager at Rentapen Inc met with the management team at a large Original Equipment Manufacturing (OEM) company that has been a customer for over a year.  Peterson went to Georgia to take a tour of their plant and to see the products that they are producing.  This visit was designed to better understand their needs, so that the weld fixtures that Rentapen creates for them are designed and built to their desires.

“We want to be their one stop source for all of their weld fixture design and build needs,” said Engineering Manager of Rentapen, Blake Peterson.

Rentapen Inc, uses their own line of RAPid Tooling Components™ to design and build the special types of change over fixtures required by the Georgia OEM company.  The change-over fixtures allow the company to best utilize its manual and robotic weld cells and keep costs down for their customers.   The main table and rotating mechanism stays the same.   Each fixture is created on a plate that mounts to that main table.  This allows the Georgia Company to put more than one cell on a product to meet deadlines.

3D Models

Rentapen’s RAPid Tooling Components™ consist of RAPid Blocks™, RAPid Plates, RAPid Risers™ and RAPid Shims™.   Rentapen’s website makes it easy for CAD Drafters and Engineers to download the right block, plate, riser, or steel shim pack for their machine design needs.

“The quick change-over plate style weld fixtures are perfect for our RAPid Tooling Component line,” said Susan Straley, President and Owner of Rentapen Inc.  “An OEM may make only 50 of one product and then have to use the same station for producing a different product.  They can put the first fixture in storage until they need it again.  The speed of the fixture design and build, the adjustability and the accuracy provided by our components are keys to a successful weld station for an OEM.”
