uninsulated terminal crimper

Yet another crimping tool. I have too many: There's another dozen or so assorted tools for D connectors, insulated lugs, uninsulted lugs, telco plugs, ethernet plugs, Nicopress, etc.

For uninsulated lugs, I have one these: However, it's single indent, not double. I think I paid $10 at a garage sale.

You didn't specify the range of wires gauges needed, so it's going to be difficult to find you a cheap crimper. Panduit CT-1570 does 22 to

Crimping solid wire can be a problem. The connection works loose over time as the result of heating and cooling. This can be accelerated by high current in the resulting contact resistance. Heater wires are often welded or bolted together.

Most of the crimping tools I'm familiar with are intended for stranded wire. But what if you crimp solid to sufficiently large stranded wires? If the two wires are crimped together in a single crimp, the solid wire is just another strand.

Crimping pliers $10 to $20 on aliexpress,

die sets about $3 possibly style 102 here:

Or riveted, with sizes of rivets you can't find anywhere.

Thats a real interesting possibility there. Never though about using standed wire as space filler around a small solid lead. Standed wire seems to have enough give to keep connections real right. There's no springiness with solid crimps to really keep things tight without the correct crimps and dies. Even properly done solid crimps tend to be sort of flakey of you move the wire enough.

The upper right die almost looks correct, but there's no specs on that grab bag of dies and they look real rough in quality.

I understand the tolerances are greater for solid wire crimpers, but I don't get the 10x times price difference that seems to exist for them.

There appear to be some TE "solistrand" crimpers for $125 on ebay now. Take a look at how sharp the dies are:

Except for the now Taiwanese handles (my AMP Pro Crimper II frames were made in the USA and didn't have the cheap tool color job) this seems to be the right item. The price still doesn't really make any sense though.

I don't know what you're bitching about- the official crimpers for DF11 terminals cost over $1K USD

DMC in Florida may have one at a better price. We get AMP and Molex equivelents from them at lower prices than other distributors.

Never had that problem. try some place that specialises in engineering fasteners, it worked for me.

$1000 for corny looking hand crimpers is amazing.

I doubt that they're charging all that much for the looks.

Thanks, I'll check it out.

What are they charging for?

Precision and Peace of Mind. If the mission fails because you used a cheap crimper it's your buttinski on the line.

They're not selling them by the millions. Harbor freight isn't likely to sell them, either.

DMC crimpers are of high quality also IME. It the mission fails because of crimp failure it will most likely be because someone skimped on crimper adjustment checks and tensile testing of an adequate sample of production crimps. If you actually do a good inspection/test routine, you will quickly understand the value of good crimpers :-).

For $1000 a pop, that thing better have some sort of pressure guage and a data logger or telemetry option. Production torque wrenches have all that nonsense built in these days where torque is sent to some computer and things stop if something is wrong.

They're selling them by more than the dozen too. It's not like a crimper frame is a new concept that has't been worked out of the dies they're using are made of a single diamond crystal.

$1000 a crimper is stepping into medical device pricing. I doubt those crimpers even have serial number.

It's not a volume product. If you think they're that overpriced, sounds like you have a business plan to put together.

I'll have to look at mine.

We've got a few crimp tools, I think they were all ~$500 or more. We use cheap crimps onto spade or ring connectors. I always solder 'em too. (the cheap ones.)
