Hi. *I am building a very cheap mdf cabinet for our laundry. *It will
have 3 doors (720mmHx600mmWx18mm) and we want hidden hinges. *To keep
costs down we are thinking of making mdf doors rather than buying
premade wood or particle board doors (diff is about $150!)

My question is: how can we attach hidden hinges to mdf? *Is it
possible? *The mdf is only 18mm deep, so after boring out the inset
hole in the door will mdf bite the screws enough to attach the hinge?

Will the weight of the door make a difference (720mmH x 600mmW)

I can always bolt the hinge on the inside upstand/support so I am not
too worried about that side of the hinge, but I am worried about the
part that attachs to the door itself.

All help and advice appreciated

Most hinge cups for hidden hinges are approx 12 mm deep. They carry
the load. The screws merely hold the cup in place.
The weight is well within range of a decent Euro hinge. I said a
decent one. Blum or Grass.
The ones to get, are those hinges that come with barbed plugs already
attached to the screws and you bore a (8mm?) hole and pound in the
whole assembly with a hard rubber dead-blow. You have to be pretty
accurate with the hole location.
I wouldn't go near a project like this without a drill press.
