Materials science / A couple of questions about basics of laser cutting
« Last post by cdhtac on April 01, 2020, 08:37:01 AM »
Ok, i've been planning on coming up with my own shooters belt design, and instead of using webbing to create the pals-matrix, i figured using laser cut pals would save a lot of time and make the belt more affordable.

Now here's the problem; i know nothing about laser cutting fabric. I am of course going to outsource the cutting, but is there anything i should know about laser cutting?

How about the material; would ACRONYM 500D laminate do the trick?

Do any of you guys do cutting on order? I would like to try the design first before buing a lot of materials

I've had to supply power to several of my own machines (not sewing machines) set up for 3ph power...lathes, mills, large saws..etc. I currently use a "roto-phase" type converter rated for the largest HP motor I use. This unit is powered by a normal single phase 220V input, usually available in most residential load centers. Some of the larger saws I have used in the past were supplied with "static phase converters" which are small, quiet and all electronic, but note you do take a small HP hit with either the rotary or static converters. I believe the hit is less with an actual rotary, but that is probably an academic concern with most industrial sewing machines which do fabrics. Variable frequency drives are normally used to provide a 3ph motor with some programmable or on-demand functions like speed control or reverse etc....nice if you need or will use it, but you will most likely just want the 3ph conversion to supply the main input on your machine. I'd investigate a "static phase converter" and see if you can determine if there are any gotchas which lie in wait if your main connection is ONLY the 3ph input, and the brain on your machine steps down and converts all the power and voltages for the other electronic/computerized functions.

Depends. If you need the functions of the control panel get a phase converter.most phase converters I have seen have a 240 input though. If you can live with out it get a servo.

This is what I am trying to figure out. Thanks. So the control panel needs 240. I did contact Brother and they have a "transformer" but I'm not sure he understood the question:


Thank you much for contacting us with your request.
We do have a transformer to convert the machines from 110V to 220Volts.
Your machine was one of our best selling models and most of them still running in the market.
 
For this machine we don't have any motor replacement and parts are discontinued.
Our part number for this transformer is BMP301000000002ST1.
 
thank you much

Hello,
I operate a sewing operation in Alaska and have the opportunity to pick up a Brother DB2-B791-415. It is set up with a 220v 3 phase motor. I am inquiring whether it is possible to simple convert the motor to 120v single phase or if the e-40 control panel and other electronics requires the 3 phase power as well. If the conversion is possible, would Brother USA be able to sell me the new servo/motor? If it is not possible to convert the motor/servo, will a VFD phase converter allow the machine to operate correctly?

Hi there, been lurking on the forum for a while and finally joined.

Presently doing some small modifications to existing kit and generally making a mess of nice fabric with my dinky consumer Singer machine.

Cheers!

Concept, design, and engineering / Re: Bringing a new product to market

Ok. So we have two prototype bags on hand and both bags have been used in an operational setting. So what it sounds like, is we need to reach out to whichever companies, pitch the design, and see if they will pick it up. I imagined it would be a little trickier than that.

Thanks for the information.
Well, you need to persuade them into actually buying the design off you, which is the hard part. Everyone has a medic pack, so why should they buy a design off you for an outrageous sum of money? Unless you can guarantee them sales, it's probably not something they are interested in. It's like Dragons Den but in real life, so you better have your pitch be on point, with numbers and facts.

The absolute easiest way to get a product to life is to pay someone to build it for you. You send them a prototype and they make it nice and make many of it. The only real requirement here is money, and prototypes or tech packs are very helpful but not always needed. The hardest part here is to sell your product, but there are probably more willing retailers than there are brands if you don't think you can manage to push the product yourself.

As an example, I've been helping out this dude that wants to make a uniform for his brand. He basically had 0 idea about how anything works, and after about an hour we had a plan that he had to execute and a month later he had a prototype in his hands made by a manufacturer he found. Then we went over the prototype, made comments and waited another month or so. The 2nd prototype was pretty damned good, and the 3rd was approved as far as I know. He only had a couple of uniforms as reference and some fairly crude drawings that he brought to the manufacturer in the first place. Now very soon, he'll have a uniform to sell. As I told him, a monkey with money can have anything they like produced.
