gluing or repairing plastic bits on HPLJ

A

Alan

Several small plastic parts on the shell of my HPLJ5P have snapped
off.
Things like locking tabs and catches. I have a bit of bent wire to
hold the rear door closed now ... inelegant but working.

I wonder if I can patch it up, as I have most of the bits that have
snapped off. I think the plastic is ABS. Is there a glue that will
make a strong bond with this that can take a little flexing, as when
you open a catch to remove a panel?

Superglue (cyanoacrylate)?
The pipe glue plumbers use for plastic pipe?
Epoxy?

Look for "hot melt string " and then soldering, in effect ,on my 3 tips

if not strong enough , reinforce with woven glass mat or expanded aluminium

Really hard to say, because there are so many plastics in use these days.

In general epoxy and super glue work by the strength in the bonding
process and the inherent glue materials. Other plastics require an
appropriate solvent, such as found in ABS adhesive or for styrene, for
instance.

I have found the only way to get some plastics to adhere is to literally
melt them with heat, but that gets really tricky.

I would suggest a bit of experimentation, unless you are sure of the
plastic type, in which case you need to hunt down the appropriate
glue/adhesive.

These days it is a lot more difficult to know what plastic type is in use.

Sorry I couldn't be more helpful.

There are several kinds of adhesive that will bond ABS but I'd not put a
lot of hope in bonding snaps back on and expect them to hold up IF they
have broken off at the root. Think your best bet wold be to use a
solvent. Might give it a try with one of the plumbing solvent for ABS or
even MEK. Typ CA's, superglue, don't have very good impact strength.

Is that a two part epoxy product? I think I had a product like that
which was metallic grey in color. Is that the same stuff?

There are many ways to effect a repair. The JB weld epoxy works great.
Rough up the parts before applying. I like to back up a repair when
critical. For example, I will sometimes wire parts together and then
overlay with epoxy. The result is like concrete with a rebar inserted.
Sometimes you have to ask whether some of the parts are even
necessary. I cut access doors on my printers and duct tape the plastic
back so the result operates like a hinge. This way I can work on the
ink carts without the printer turned on. It all depends on what you
are looking at.

Lay the problem at them. They will have any best solution.
