New razor blade manufacturing methods!

Hi,

I am a freshman mechanical engineering technology student at Rochester Institute of Technology. My final project is to find an alternative manufacturing process to current razor blade manufacturing processes. However, I only have a rough knowledge about current maunfacturing methods. I know that they are made of stainless still stips by perforation followed by grounding and stroping.

I would be pleased to learn new websites, manufacturers, videos, pictures, any kind of information in completing my project.

Best Regards

In this thread (the first post) you can find a link to a video of Dovo's manufacturing process. Rasurpur sells a DVD about Thiers-Issard's manufacturing process. And I know there's a DVD of Mastro Livi making a straight, but I don't know where you could get your hands on it, perhaps directly though Livi's website.

Good luck.

Stainless steel strips being perforated? Sounds more like multi-blade cartridge technology or DE blades/disposable blades than a straight to me.

My co-owner used to work at Gillette (IT dept), and during one open house we went to tour the manufacturing line. The way they make all those cartridges is they make a 1/2" wide strip of metal, make one side sharp, then punch out the blades.

I believe (it was a long time ago) they said they also made coils of it for the military -- clipping it to make little tabs. Nasty stuff.

The thought struck me, but then I though who's going to go to a forum called "Straight Razor Place" and ask about safety/cartridge blades? :shrug:

A young student who doesn't know what a straight razor is...maybe?

You might be able to turn those 1/2" strips of metal into a straight razor if you punch out 3" bits and mount them on something for support. Or even better, Dogukan is gonna try and convince Gilette how to make straight razors;)

Well sure - I mean, if you didn't know what a straight razor was (not saying this guy is in that category, but just for the sake of argument), then "Straight Razor Place" could have lots of meanings...

eg a place where straight guys go to talk about razors.... :thinking:

disposable replacement str8 blades :hmmm: that might just work

Didn't Edward Weck make that work back in about nineteen hundred and ought nine? :D

:HJ didn't someone ask for help?

Heads up gents

This thread is over 4 years old so you might not be getting answers from the guys that posted back then anytime soon, then again you might

g

On Youtube, you can find short videos of disposable razor blade manufacturing like this one here. Watching that five minute video, you'll see that manufacturing disposable double edge razor blades is a fairly simple process completed by rather complex machinery.

You need to hook up with an engineer who works in the R&D department of some razor blade manufacturer and develop a student/mentor relationship with him/her. Every manufacturer, no matter what the product, is always trying to increase their profits by lowering the cost of production or speeding up the production line without product quality suffering. That's a major goal of their R&D departments (among other things).

As a student, you will need to find out from your mentor what some of the problems are his department is working on to achieve the goal I mention in the above paragraph. Now, manufacturers of most products jealously guard proprietary information concerning manufacturing processes from each other, but you might be able to get your mentor to describe their problems in general terms. Coming up with real world solutions to those problems ought to be considered a successful completion of your class project. Discuss that with your professor.

So how do you actually hook up with this hypothetical engineer/mentor? You'll have to think outside of the box, but I'll give you a hint. Read What Color Is Your Parachute? 2012 by Richard N. Bolles. If the RIT bookstore doesn't carry it, you'll find it in your local Barnes & Noble.

And who knows? If the razor manufacturer likes the solutions you come up with for their problems, they might even offer you a job when you graduate.

Ggod luck with your project.
Namaste,
Morty -_-

:thinking: Oh, I missed that.

Duh :gaah:

And yet look at how many people have responded to this old thread in just one day!

Great video Morty, thanks for sharing! I'm curious, with regards to straight razors, do any companies forge them the way samurai swords were forged? Heating and folding and beating, repeat?

I would imagine you'll find the members who would have an answer for you on "The Forge" forum, under "Maintenance, Repair, and Restoration." Those are the fellows who use backyard forges to make razors from a hunk of steel.

Duh... this is an OLD thread.

Do a patent search to get a handle on the modern tricks of the trade.
Some razors on the market have patents on the box. Bring a magnification
glass to the store .... ;-)

The tricks they now use go on for pages and pages.

PTFE (teflon) is one critical coating. It has an interesting problem
well described in patents where the heat to fuse the PTFE on the surface
risks damage to the temper. Timing is critical or the batch stinks.

Other tricks are ultra thin layers of exotic metals (Pt and Cr) to help
control erosion and corrosion. Ceramic sputtering.. is yet another
trick.

Some blades are chemically etched to leave the thinnest polished edge.

Some blade steel is case hardened with heat and nitrogen rich
gas. There are some special edges that have vapor deposited diamond
coatings. Laser surface conditioning....?

There are other issues... speed, packaging, inspection, mounting,
guards, cleaners... and shave quality.

This is not a slam dunk freshman project... the art is fully developed
and rich in trade secrets and other intellectual property.

Heck look at "methods" to recover, reclassify and recycle diamond abrasives
in the razor grinding and honing lines with environmental improvements.

Or skip the sharp edge bit and focus on some other aspect of the product.
