As far as why it takes so long for me to get the sales up and running again, it's because I am broke and have no one that I know (well before recently) that had any money sufficient to get manufacturing launched properly. I have to order parts in small batches and because of that pay a high price. When a machine shop has to set up their machine and run parts, and only run a few parts, it's a nuisance job and not apt to make a good profit for them, and so the prices of parts are far higher than if I ordered parts in the thousands.
The quantity thing... Tough to get around that... Material is cheaper in quantity. I went to buy 5 sticks of aluminum the other day. $40 bucks a piece..
Asked about going to 10 sticks, $25 a piece.... So I got to double the material for 25% more. If I went further it should have been around
$14 a stick.
As far as making small quantities.. That can also get expensive. Have you thought about offering a blanket order to get your cost down.. What I mean
is a minimum of so many parts per month for so many months.. A little more risk on your end, but the shop can order up material for 4 months of
production, run it all.. Pay off the material the first month, eat the labor and time, but then its all gravy for them the next few months.
I do this a lot with one customer... He needs 2 parts now... I don't want to set up and run just 2 parts, he doesn't want to pay for me to run just
2 parts... He buys enough material for me to make 40, and then I sit on them until he needs them. He pays a slightly higher price than if he took and
paid for all 40 at once, but he pays far less than if I had to set up and make just 2 parts. And down the road, I get a nice little stream of essentially
free money for doing nothing but writing an invoice. I take it in the shorts a little on the initial production, but once I get it set up, it just runs and I can
go off and do something else.
If you pay for the material yourself up front, that can drop your cost too... A machine shop isn't a bank, and they need to get something back for
essentially loaning you money, so they are always going to mark up the material a little bit. There is also the time involved in getting material quotes,
writing the purchase order and then having to write the check.
Also on the side plates and the sheet aluminum you are using.. Are those being machined or do you have somebody cutting them with a laser or a waterjet?
I assume for now you are doing the assembly and packaging and shipping yourself? That can save you a bunch, or if you're too busy with a 9-5 job and family,
get some kid down the street to do it, it'll be far cheaper than having a machine shop do it.
A lot of ways for you to cut down your costs, until you get a decent volume of sluices going out the door.
