Other Possibility to mass produce anything via injection molding

[meatball]

Recently on a business venture my brother got set up with an injection molding company that can do various plastics such as ABS, delrin, Nylon, glass filled nylon, etc. I got to thinking that there were some parts on superjets that could be duplicated such as stock F/A's and the electrical box. I wanted to see if there was any interest in doing an electrical box cover that would allow the use of hex head bolts versus the tapping screws. While there is a huge startup cost associated with the making of the mold, if there is enough interest in just about anything made of various plastics, then it is very feasible with my brothers current connection at the company.

So what do you all think? Ebox covers that dont use self-tapping screws? Stock F/A (the price would have to be similiar but it would function the same and look a little cooler), anyone else wishing something was made that didnt? Also let me note, if you have CAD files, I have access to a prototype printer that would allow testing of any parts before injection molding is pursued. Any thoughts? They also do mass produced CNC parts

A hull!!

what company you using?
Are the mold built in state our off shore?
Are they going to sonic weld or heat steak inserts in them or even over mold the inserts?
I think to even break even your going to need a ton of intrest.
as a mold builder i would be interested in what they say.

Just an fyi, SBT makes their replaceable impeller housings out of Dupont delrin (used for cutting boards).

A hull!!

Yes, a 6 foot Delrin hull that will fw back flip with a stock 650 !

wow that was quick guys!

At burton, Id rather keep the company name a secret if you dont mind, not sure how my brother is handling this. They are completely US based, so none of that Chinese crap where every 10 you order 3 illegal copies go out the back door. I'm not sure what your next question was, to be honest my brother is the one dealing with them now. He came up with a nifty thing that in order to break even we will have to sell quite a few units, however they are probably going to be about $10-$15 a piece, so a bigger piece would probably be easier to be profitable. And yea guys, I am aware thats what SBT does, and actually I looked into it, and I would definitely be willing to consider having a mold made for delrin wear rings, but I dont see the market for it. Those inserts are for nonstock pump rings provided by SBT right? And I looked into the pricing models and cost to start and it would take a few hundred units sold to break even.

The most important thing I can say is that parts with somewhat small dimensions (like ebox covers and wear rings) can be prototyped instantly my brother has a printer, so if anyone has any ideas, they can be tested! Also about a hull, guys the labor required to make an injection mold for a hull would most likely be ridiculous but Ill look into it just for kicks, not even sure they are capable of such a thing, and more importantly if I dont get the dimensions right the first time, I would have to spend all the money all over again for another mold, so its risky. Also, delrin I think would be too heavy and not really the right qualities, I think ABS or glass filled nylon would be a better route.

Rotomolding is the way to go for this, same way Kayaks are made. If someone invested the initial $$ for the moulds, the hulls would cost about $200 a pop to produce.

I am aware of how cheap it is once the molds are made, but it would take a lot of skill deciding how thick and where, and what shape the hull should be is completely different in preference from person to person. Like I said Ill look into it

Mag style pump with wear ring housing all in one.. It would weigh like 3lb

O ya make the vane section 150mm so you could sleeve it for 146 up to 150

 

[shaunsteezy]

my buddy and i were talking about this the other day. you should make an e-box cover w/ clear platic so you can see inside and also have brass inserts in it so you dont crack the plastic when you tighten it. do it. ill buy one

 

[meatball]

A pump is a possibility, but seeing as how it wouldnt be steel Im not sure it would handle high-horsepower skis, plus it would be more susceptible to damage from debris. However the cheap cost just might be enough to offset those disadvantages, that is, if it can withstand the pressures involved.

Clear head so you can watch piston wash lol

 

[meatball]

with the amount of pressure and heat involved, I doubt it would hold a seal, would probably warp after about 5 minutes

I hate to be a naysayer, but you'll never produce/sell enough parts at a reasonable price to recover your tooling costs.

 

[Freakrider]

First off before ski parts, makes us a delrin paddle so we can all spank our girlfriend or wife when they get out of line or biatch.

 

[964Chris]

how bout a decent coupler cover??

I hate to be a naysayer, but you'll never produce/sell enough parts at a reasonable price to recover your tooling costs.

I used to think that too, but then my brother found a company that does it very affordably. In fact in some instances if a product can sell for 60 bucks break even is at 25-30 pieces. Right now he's tooling for something none superjet related that has a bigger market, just figured I would see how much interest there was

i dont think i want to see a 1500 mold lol
