They cost 4-5x less than "custom made" crimping tools made by "professionals". I've ever seen company moddiy selling exact same model at "premium" price.

https://img.banggood.com/thumb/water/upload/2014/12/SKU188588/5.jpg

SN-28B seems to be not viable for AWG16 cabling but the SN-48B model is meant for them also it has two crimping stages one for the insulation and one for wire.

Anybody used them and can share opinion?

there was a discussion awhile back in another threads about these crimps. They did a horrible job at crimping due to the teeth (some of them don't even have the teeth in the dies) & person who was using them returned them. He then went with the crimper that MDPC-X makes with allot better results. It may save you some money but in the long run it's not worth it due to issues they can create.

There’s a ton of variation between “SN-28B” crimpers, so there’s no guarantee that the one you get will work. My recommendation would be to spend the money upfront on something that is known to work. Buying cheap tools usually costs more in the long run due to wasted materials and time.

The MDPC-X is the same, but more expensive. The only difference is logo:)
I couldnt find the silver toothed one in place i bought it from, but anyway, this is how it crimps:

Not perfect but not too bad. Large wings bite slightly into insulation, the little wings dont wrap around wires, they rather form a square. Also, i have to crimp single connector twice, first time on the largest slot and then do the final crimping on the middle one.

Good work!

[quote name="SomebodyOnce" Large wings bite slightly into insulation[/quote]
That's good! They keeping the wires from disconnecting

Try to crimp only in the middle one. If there everything good? Or the wings didn't go simmetrically?
With good crimper there is no need to crimp twice

With just the middle one the part around wires gets more flattened out. The listing page on Banggood would say its SN-48B tho the box it came in would not have any indications of model on it but the tool itself looked exactly like in the photo. Cost me $15 including priority shipping (2 weeks delivery time instead of 4) acceptable price and quality for me considering it will be dumped into a toolbox at the bottom of the wardrobe once i finish cabling for my PSU - "brand" tools would cost me around $70 (includes tax).

I'm also have a bad crimper plier, like you have (left on photo):

I bought new crimping plier and replace it - upper crimper (good for two wires)
Middle crimper - for ATX/PCI/EPS
For fan and dupont pins - down crimper
I'm wait for delivery of full analogue of MDPC-X for compare with simple crimper SN 28B

There is a difference between MDPC-X and generic tools. CTX3 is much different then all those listed. Teeth and slope are slightly different which is formed to Molex standards. The spring on the tool is also very different.

But I'm still use my favorite tooth:
I still favor Molex when it comes to wire strippers, much faster and easier to use then those style of strippers. Plus Molex covers almost every gauge thickness

Have not heard of that brand so I can't really say, If it's near MDPC-X quality then it should be ok. MDPC-X CTX3 is still my favorite racket crimper with PA-09 & Pad-01 being my favorite crimper when you need to see the wire and require more precision.

It's nice to have teeth for both style of terminals(Open & Close). Hopefully it's been molded to Molex specs.

btw, it's teeth. More then one = Teeth

I assume most here are talking about small gauge wire. I'm looking to crimp female terminals on 16awg wire for some custom PCI-e cables I am making. The first set of crimpers I got from amazon (Iwiss SN-28B - http://amzn.to/2hKg8Zq) did not work for me at all. 16awg is just too big. Then there is the terminal issue. The ones I bought are not made for 16awg wire but I was told they would work. Turns out they have smaller wings on the back and you just can't get a good bite. I don't think you can even do it with the right crimpers So I have two questions.

Which of these crimpers works with 16awg wire and PCI-e terminals?

what model would be a more appropriate PCI-e females terminal for 16awg and where can I get them at a good price with fast shipping?

Not too much to ask eh?

TIA

You can get 16AWG terminals (Molex 39-00-0077) from Digi-Key https://www.digikey.com/product-detail/en/molex-llc/0039000077/WM3112CT-ND/1643460. The MDPC-X CTX³ crimper will work with 16AWG terminals and wire.

I'm usually pretty good at finding these things but for some reason I''m not hitting the nail on the head with this one.
As far as I know, mod-one is only place in the US. You can also get the 16AWG terminals and wire from them.

Here is the thing most people don't realize, The part of the terminal that actually holds everything in place is the Conductor (the part that holds the wire strands down). The Sheath just gives it an extra hold (Basically a fail safe). The Sheath doesn't need to bite down on the wire as long as it makes a circle on the wire it's fine.

Also make sure your wiring OD meets the spec for the terminal. There are some very large 16 AWG wire with massive OD. Which will not work with Mini Fit Jr. terminals. Try to stay around 2.5 OD, Even though Molex terminals will accept 3mm OD wiring, You need to take into account the sleeving which will increase the OD and you still have to get it inside the connector.



^ As long as it looks close to large "Molex" terminal the crimp will hold. These crimps were done by MDPC-X them selves.

CRIMPERS

CTX3 will do 16 AWG without any issues, It's what I use to crimp 16 AWG wiring. The crimper can even do 14 AWG wiring & terminals if needed. 14 AWG for a PSU is overkill.

There is also the molex Branded Crimper if you got the money.

Link: http://www.molex.com/molex/products/datasheet.jsp?part=active/0638190900_APPLICATION_TOOLIN.xml&part=active/0039000038_CRIMP_TERMINALS.xml

----

There is also the Engineer PAD-01 which will do almost every Wiring size possible since it has a swapable dies.

Link: https://hobbyking.com/en_us/handy-crimp-tool-complete-set.html

Engineer also makes PA-20 & PA-21 crimping tool which can crimp 16 AWG without any issues. There also the PA-09 which is designed for smaller terminals like Fans and smaller (aka Pico most annoying terminal ever made).

Link: http://www.engineer.jp/en/products/pa21e.html
Link: http://www.engineer.jp/en/products/pa09e.html

I have used all the crimpers listed except Molex version since the price was to high just for Mini Fit Jr. crimper. All will crimp the terminals properly.

In the US Mod-One is the only supplier for MDPC-X. MDPC-X does sell it directly from there webstore and are fast at shipping. Shipping cost it sometimes even cheaper then buying it from Mod-One. If you buy Sleeving in bulk you want to buy from MDPC-X directly since it will always be cheaper.

Mod-One is only supply in the US for MDPC-X, Just be careful when buying since they sell a few different versions of Female ATX terminals. From OEM to Molex. The molex versions of the terminals are all tin plated, They do not sell gold plated versions which is the version I prefer.
----

MainFrameCustoms also sell modding supplies, Some of there product descriptions are very mis-leading. They claim there molex branded but there just OEM but based off Molex specs. There pictures don't even match Molex terminals. I stopped using MFC awhile back since all there products have taken a drop in quality. Even there heatshrink is horrible to use now.

A few related questions: I'm planning to make 16AWG cables for both ATX (to motherboard) and SATA push-in, using genuine Molex brand connectors and terminals from mouser.com and/or mod-one. I don't plan on sleeving the cables, so I'm looking at mod-one 2.0mm (or possibly 2.4mm) wire which is nice since it doesn't have any writing on it and should be easy to train. I'll be using an MDPC-X CTX3 crimper. My questions are:

1) will the mod-one 2.0mm versus the 2.4mm wire crimp better (especially in terms of stress relief on the PVC portion)? (As I mentioned, I don't care about which is better for sleeving since I won't be sleeving.)

2) do you happen to know the Molex part number for the mod-one 16AWG genuine Molex ATX female terminals?

3) are there higher end quality Molex part numbers for 16AWG Molex ATX female terminals that I should consider as a "step-up" from the ones that mod-one sells? I was looking at Molex's part list here, but have no idea if any of them are better?

Sorry I`m a total noob in custom cable but I want to crimp molex and general psu cables and also some jst and jyk connectors for my 3d printer. Would this crimper do it all ???

Yes. PAD-01 can go below 1mm pitch and above 5.08mm pitch. Take a look at Engineer website they have a datasheet of what terminals have been fully tested. All PSU terminals from Molex will work with Pad-01.

Keep in mind that the Engineer crimpers are non-ratcheted and crimp the conductor (wire) and insulation separately.

Read the instructions that come with the crimpers. Since your don't want to overcrimp the terminals. It will explain how to do each part of the terminal. When inserting the terminal into the dies don't let the wings bend in if they do move it to the next size up. You only need to add little pressure to the tool, don't put your entire strength behind it.

Also something I found useless, Is hold the front part of the terminal while crimping, so it doesn't bend. This is more for the larger terminals like Mini Fit Jr and "Molex".

If the jaw thickness is similar to the PA-21, crimping the insulation first seemed to help with the bending on Mini-Fit Jr terminals.

The dies are slimmer, the width of each die is also slimmer. Each slot is also wider compared to PA-09 or PA-20/21, the teeth are also a bit sharper as well (Close to what you see in CTX3). You don't have allot of room to keep the terminal balanced. Some have modded the tool with a flat plate on the backside of the tool, Which will keep all the terminals straight during crimping.

Pad-01 is still one of the only tools that will crimp just about anything, Racket crimpers have problems after the terminal hits a certain pitch.
