Other Cost reduction project for school was wondering if you guys had any ideas????

[JETSKIHORDER18]

I am at the Rochester Institute of Technology for Mechanical Engineering and I have to do a cost reduction project and was wondering if you guys have any ideas. I need to find a part that can be manufactured cheaper than it already is. I wanted to do something with jetskis because thats what I love. So let me know what ideas you guys have. It can be a single part or an assembly of two or three parts.

rotamold the chambers from hi temp plastic resins
and pop them out for $20 a piece!

i was thinking b pipe but blow molding with hi temp plastic but rotamold would work too.

B pipe chambers aren't that difficult and thus a lot of copies have already been made...although most are more expensive because they're carbon. I still don't really understand that but whatever. Looks add power I guess. If you do go with a b pipe chamber, keep temperature in mind. They don't get that hot normally but I'd be leary of spending hundreds of dollars on a part that may be trash if a water line got clogged.

Some things that would be nice to have and you always see WTB threads for are clean gas tanks, stock RN waterboxes, and long exhaust hoses. These are perfect examples of needed items that are hard to come by because OEM parts are impractically expensive. Think outside the box too. Doesn't have to be a direct copy. Metal and composites gas tanks are nice. Tanks that include a battery slot are excellent as well. The long exhaust hose doesn't have to be all rubber either. Could be rubber ends and composite/metal in the middle.

On second thought, a real Jetski wetuit like the oldschool Jet Pilot suits or early Slippery. You know, with the padding on the knees and shins instead of the A$$ for sit down style suits. Those old suits were great, especially the Jet Pilot "Ultralight".

i like the b pipe idea becasue there is big need for that product, if someone made cheaper chambers and with good quailtiy i think they would make money i wonder why nobody has done this, factory pipe still makes and sell the pipes i am sure they are making money from this no matter what anybody says, supply and demand is very simple there would be a great demand with a lower price

I was going to do b pipe but we cant change the material but I will talk around and see if i could find some one with a blow molder and maybe try out a b pipe. But with this project I can not change the material of the part just the process like milling to wire edm or like cnc.

that would mean something intricate, like a removable dome head perhaps?

what about a aftermarket driveline coupler, insted of turning the outside diameter then seting up another machine to drill the bore and chase threads and seting up a milling machine to cut the (fingers) makeing them on a duel spindle lathe with live tooling would be a lot faster and could be cheaper is this what u are looking for?

 

[JETSKIHORDER18]

that is an excellent idea. I will run it by my professor and get back to you thanks!

Called a few companies in rochester to get an approximate cost of blow molding b pipes and the tooling cost was 12 to 15,000. Definitely not in a college freshman's budget at this point. I am going to try to find some other ways to do it poss a little cheaper. In the mean time i am going to try to make a few out of carbon and some out of glass and do some tests so i can make some pipes that dont cost a sh$$ ton of money.

If you had a CMM you could take a bunch of dimensions off the b-pipe and and model it in ProE or Solid Works, then make a reverse mold for composite layup or blow molding. Hardest part with blow molding is making a suitable plug (whatever it's called, can't remember) that is then blown to shape in the mold cavity that doesn't have serious thin spots.

thats exactly how ours at Cold-Fusion are made, multi axis lathe with Live tooling

BUT you must take into consideration the cost of the equipment in the equation for a true return on investment, HASS mill and Lathe under $80 K investment
Mori seiki multispindle lathe with live tooling $350 K investment

idk if it was you but I have called cold fusion a few times and talked with you guys about a few parts but there is no room for improvement with your parts you guys have mastered it all thanks for the help!!!

And I am starting to make molds now for a carbon fiber handle pole, then after some testing I will start producing them and hopefully selling them you guys on the X. After the pole will be carbon ride plates that are made with 100% carbon, they will be d cut, w cut, or no cut, and at the same time hopefully some molds for b pipes. I will keep you guys posted!
