Custom Bonded Blocks Saves You Time = Money

Wouldn’t it be great to save yourself time and money on that bonded block and have it delivered, ready to machine?  Precision Board custom-bonded blocks are designed from the ground up to save you time, material, and money.  All we need is an isometric drawing to provide a quote.  Our skilled production team can assemble complex step tools of any size, any thickness, and any density.  We deliver your custom bonded block directly to you so that you can start machining right away.

For our proprietary bonding method, we use our own EP-76 epoxy adhesive filled with our PB Granules to match the material density, resulting in very tight and strong bond lines that are almost imperceptible.  These bond lines provide smooth machining throughout the finished tool.

We cut the sheets to size, carefully bond them together, and ship the assembled bonded block directly to you. This means you can start machining as soon as it arrives, instead of wasting days or even weeks bonding it yourself.

The Aerospace and Automotive industries have relied on us for years to bond custom Precision Board Plus blocks for their unique tooling needs.  There’s virtually no limit on the size of blocks we can bond. We’ve built and shipped some truly massive tooling blocks for customers around the world. Rely on our bonding expertise to get a near net-shaped block ready for you to machine in the time frame you need.

Custom Tooling Blocks Save Time, Money: Here’s Why

In addition to manufacturing the largest and thickest sheets in the tooling industry, Coastal Enterprises also offers an additional service to our customers: custom-bonded Precision Board tooling blocks.

“Some of the layup tools we made at Skunk Works were absolutely massive, which meant CNC time was a major factor when determining project deadlines.  Coastal’s custom bonded blocks saved us hours on the CNC and ensured we stayed on time and on budget – they are the true gold standard in tooling efficiency.”

– Jon Sharp, former Lockheed Martin employee and air racing legend, on why custom bonded blocks were their go-to choice for large tooling jobs.

Advantages of custom tooling blocks:

  • Save money by using less material
  • Decrease machining time by being closer to net size from the start
  • Arrives ready for immediate machining

With only a rough drawing of your finished part, we will fabricate a custom block that will significantly reduce waste, bonding/laminating time, and reduce time spent machining.


Save machining time and material cost
By layering the sheets of Precision Board Plus PBLT-40 with just enough excess to accommodate the customers tool design, we saved them hours of machining time. Think of how long it would take to CNC machine a solid block down to this shape! Also think of the cost savings on tooling board. Call us at: (800) 845-0745 with questions on your project!



This custom block is made out of Precision
Board Plus PBLT-10, and was machined into a mold to create one of the three composite body sections for the landspeed record-holding Speed Demon race car (see full article here), operated by George Poteet and Ron Main. In addition to buying less material, they also saved money by eliminating the plug process.

A pioneer in the use of soft tooling, Jon Sharp  shared his opinion on the advantages of custom-bonded tooling blocks with us in our previous article featuring him and his time at Lockheed Martin Skunk Works.

“Another major reason we were so drawn to HDU for tooling was the greater level of design flexibility that was suddenly available. We used to order our blocks several inches thicker than we needed them, which made the inevitable design changes much less of a headache. Could we have done that with metal? Absolutely not, we would have had to start all over again.”

Whether its a composite layup tool, full-scale model, prototype, sculpture or other project – our custom tooling blocks will help keep you competitive, on schedule and on budget! Please contact us for additional information, or visit our Custom Tooling Blocks webpage.


How Will A Custom Bonded Block Help Your Business?

Coastal Enterprises bonded blocks – increasing your LEAN manufacturing efficiency! By arriving ready to machine, custom bonded blocks eliminate bonding, decrease machining time, and use less material than purchasing sheets or blocks and bonding to size.

Send us a drawing and we will build a custom Precision Board Plus HDU block to meet your specifications. Our bonding technicians have over thirty years experience building complex tooling blocks and our high strength EP-76 bonding epoxy has the capability of matching the durometer of the tooling block. This means the bond line will be the same density as the material and won’t affect your cutting tool when machining.

Shorten your deadlines, extend your tool life and eliminate the bonding step – get a quote on a custom bonded block today!
