We have a plastic cake dish that isn't used for much except containing, i.e. it doesn't need to look pretty. Recently it got a big ole crack in it, and I was charged with the job of fixing preventing any further damage.

Using some plastics glue I picked up for this project, and a toothpick, the cake dish is now all better.

Not warranting a full instructable, I smeared some glue in towards the edge of the crack, where i could fit it, and then covered the crack, on both sides, with a layer of glue to hold it together.
Take a note from the Liberty bell. Drill a tiny hole at the tip of the crack. If it must be "caketight" fill the hole with food grade epoxy after the crack glue has set. By turning the end of the crack from a point to a round hole, it'll prevent propagation.go slowly and carefully with the drilling though(or even try using a scrap solder iron tip to melt the hole). Drilling older brittle plastic can cause it's own cracking! :-( but if done correctly, and carefully, the hole will prevent ANY spreading of the crack, and return your cake cover to service for a long, long time. This technique is also used to limit cracks on most any bell shaped thing... bells, drum cymbols, crystal pie servers, cast iron pots, etc. It' even used to stop cracks when repairing chocks(bearing housings for multi-ton steel rollers, used in the steel mills). For the chocks, first the ends of the cracks are drilled, then the cracks are widened a bit, the welders fill the voids, then the surfaces are re-machined and they work like new! :-)
. For hard plastics, I've had good luck using a Dremel and a fine, cone-shaped stone (although the stones tend to clog quickly). Go very slowly. . I try to place the hole a little bit (½ inch) "ahead" of the crack. Seems to lessen the chance of breakage.
Try grinding some rubber.That should unclog it.
Thanks for the idea...i'll do that later today.
Anyone can help ??? where to buy the food grade epoxy glue which passed LMBG food test by Germany ? can we buy from Hong Kong or China ? Our factory need this type of glue for manufacturing kitchenware purposes. Thank you !
