Question How do I repair a crack in Corian cupholder?

[flyboy013]

The cupholder near the passenger seat has cracked and I'm attempting to repair. I put some superglue into the crack and also mixed up and applied some clear epoxy. I reattached the cupholder a few days later after the epoxy cured. Unfortunately as I tightened the screw the glue and epoxy didn't hold.

I'm looking for ideas on how to repair. I'm considering a several inch long metal plate epoxied to the inside ring of the cupholder that would extend on each side of the screw. Thinking it may spread the pressure along more of surface area.

Thoughts?

You could fill it, sand it, polish it. But is a warranty replacement an option? (edit: confused you with FLSteve and his new New Aire)

Perhaps drilling the hole out a little so that the screw doesn't put pressure on the sides as it goes in. Is the cup supported from the bottom once in the holder? If not, I don't think just bonding it back together will hold any weight over a bumpy road.

@flyboy013 you probably already know this but there is plenty of content on YouTube on repairing and working with corian.

Thanks for the suggestions. I’ve put together a plan. I’m meeting up with a friend near Dallas over the next few days. We plan on drilling some holes and screwing in a piece of support metal in the inside circle. Using JB Weld to hold it too. The plan is that the pressure for the support screw will be in the metal and not the broken corian. I should know in a few days

Personally I think that type screw head is the wrong type. I understand that it has a nice flush top, but the underside of the screw head is applying a force that will try to split the corian.
The idea of a metal ring would help reduce the splitting force on the corian.

Repaired the cup holder. Used JB Weld to attach a band to the inside of the Corian ring. Used four small screws for additional support of the band. Reattached using a pan head screw. 3d printed a new cup holder insert so that my DW’s large cup will fit without tipping over.
