Bending Solid Surface Edges

      Advice on miter-folding methods for solid surface corners (including radiused edges). October 28, 2014

Question (WOODWEB Member) :
We have been doing cabinets and counter tops since Corian hit the market. Is anybody cutting the front horizontal edge at a 45 degree angle? Of course the vertical edge would have to also be cut this way to get the 90. If so, why?

From contributor F:
We run as a miter fold on a CNC machine. The majority of the glue joint is on the backside which reduces cleanup/sanding labor.

From the original questioner:
If I may ask further, what about a radius? How much bend is available before the SS breaks?

From contributor F:
You can't bend a radius and you need to at least ease all the edges after the fold or it can get quite sharp. If the top has a full half round edge then the stacked edge is the best method but tops with small radii and drop edges are great for miter-folding. You can fold a cove splash but there is a fair amount of cleanup if you don't have the specialty tools to clean the cove.

From contributor G:
If you miter fold and put a 1/2" radius on the edge you will have a 1/2" of glue surface which should be plenty. You could also put a Corian cleat behind the face of the edge.

From contributor Y:
Shops are using their CNC routers more and more to make the proper angle mitre fold cut in solid surface sheet. Apply a tape to the finished side of the SS and run the router bit (two or three passes) down to *but not through* the adhesive tape. The tape will hold the definition of the line and will allow you to glue the joint, make the fold and prevent any of the adhesive from oozing out the finished side of the joint.
