Need to glue a snapped plastic insert that holds my shower door on the sliders.
Will need to be very strong as supporting heavy glass.
What's best...., Araldite?
Depends on the plastic. If it is abs or pvc then solvent weld can be good. Superglue works well if the parts are clean and there is reasonable contact area. Epoxy is similar. Trouble is that any repair like that will likely be weaker than the original part and that snapped. Can you bulk the area up a bit? Maybe something like milliput
Can you not get another plastic insert?
Send a photo of the broken part to the manufacturer and ask for a replacement.
Depends on the plastic - some polymers like polyamides (nylon) and acetal might be used because of their low friction and durability characteristics but are very difficult to join using adhesives
Gorilla Glue ..well impressed with this on all manner of things ..you may have to trim afterwards as it expands .
Not sure of the manufacturer to get a replacement.
Not sure how to work out what plastic type it is. Don't think it is nylon though as doesn't have the waxy feel.
Will take a look at gorilla glue
Plastic Weld will literally melt the plastic back together provided it's the right type of plastic.

For anything else JB Weld. Two part adhesive that will pretty much stick A to B permanently.
If it's out of a bathroom it'll maybe be a low surface energy plastic. They're a pain to stick things to, a side effect of them being made easy to wipe down.
Is there an identifying mark moulded in to the part anywhere to tell you exactly the type of plastic? There are specific adhesives for most things.
I've always found Araldite to be better used as a sort of cement to hold non-porous objects in place relative to each other rather than as an adhesive to bond them.
As mentioned above I'd be trying to add extra reinforcement in the area if possible, sort of like a splint.
Get a replacement of mechanically fix it using scres, inserts, braces if you can.
Most glues will struggle with that if the contact area is small and the weight high.
If I had to glue I'd go for a two pronged attack. Join the part with a plastic weld product then reinforce around the edge with something tougher like epoxy, sugru or a setting putty of some sort (not sure on its strength?).
Surface prep is key, roughened, absolutely spotless and dry.
