the mysterious cuts

[Raccoon]

I would think quite the opposite. The cuts would confine friction to a smaller area, and increase wear where the plug meets the housing. It's definitely a drawback in that sense, because harder metals would be needed to compensate.

This is what I was talking about 9 months ago, if vector 40 is stil here

Ross make locks with those, but when removing the plug, the drivers got stuck in the gaps. not as well made I guess, but what do you expect for 50p.

I just dismantled a *very* cheap lock marked 'ACTech' - a 6 pin dimple-style lock -
and found that it had a very similar structure.

However this plug including the 'mysterious cuts'
was clearly die cast, and the remaining ribs are centered on the 6 pins.

In the case of this 'ACTech' lock, saving material really seems to be the reason.

You guys are all way off. Clearly the cuts are there for aerodynamics.

But where is the rear spoiler enhancing contact to the coupling/cam mechanism?

Only available in the next model up.

hi all
It is very cheap lock-1.20$ with 3 keys
On it there are no inscriptions and names
I have bought it in a small household shop, the seller has told that the lock Chinese. Quality of assembly is low



This lock has interesting bottom pins, they have a rough surface because are cast from copper

Can from the rests of these cylinders Chineses cast pins
Thanks for such quantity of versions of an origin of these cuts
Sorry my English

I think those cuts are used to keep the plug inside the cylinder when the key is being turned.

Some manufacturing processes are called lightening, the holes in PSP (perforated steel plate, wwll instant runway steel matting, and the sometimes seen holes in the web of steel beams, this is done in aircraft to preserve strength but make the structure lighter.) since at least one of the locks mentioned had it and it was molded not machined, it may also be to use the least material just to make more parts from the available material, perhaps lighter means easier export shipping.

I wouldnt think a box of locks with that amount of material removed on the plug would make enough of a weight saving.

If the slots were for strength they would be radiused bottoms and not square.

Ive stayed out of this thread as i do not know for sure so cant comment but it perplexes me,

If the slots were for material saving why are they differant heights on some plugs.

I like the antipull idea but i dont think it would help as you would pull straight out the lack of material may make it break but you would simply reinsert the screw and pull again.

Anti drill? well its true that air spaces in material can make the drill grab and make it very hard to drill the plug out but a fast drill with a sharp bit will get through it.

Plud id at the factory? well possable as is the clamping points idea but none of the other manufactures do that and the oriental lot are far more advanced in production situations.

They are found on the cheapest locks and ones which dont have great security.

It may be that the keyway is formed cold and that a die is forced through the plug, this plug regulary moved in the clamp so fingers hold the plug and stop lateral movement,
It may be that they are cast and that the slots are where material is moved around the mould to other plugs,
It may just be a cost cutting exorcise.

Has anyone actually fired off an email to the manufacturer? those that have bought them muct have the packageing with the details on it or go to the shop and ask where they get them then ask them.

I have made some experience with Asian manufacturers. From that I can only say: Good luck. If you find someone who speaks English, they are most interested in the good customer who buys the many locks at the best price.
Why do you have these cuts? - Yes, yes! These are the good locks with the very good quality at the best price!

"No, I wanted to know why there are cuts in the plug." - "Yes, best price and high quality and the cuts are high quality too and they are free bonus!"

Hmm, I wonder why the guy with the long nose is saying the "No". Maybe he is the very impolite guy. Maybe I will make the fun of him and sell him the locks at the double price. But meanwhile I will tell him: "Yes, Yes, these are the good locks at the best price!"

If you look carfully, the drivers aren't going to fall into the cuts. the cuts are between the drivers.

They will, if you remove the plug while it's turned 90 degrees.

Okay, in that case but normally, It wouldn't
