I might have something of interest, I will not divulge what it is here but I checked into having it made from glass filled nylon , I was quoted around $6000.00 for the mold, individual partS would be as low as $6.00 each , $6000.00 seemed ridiculous to me fiven the size of the mold but I was told glass filled nylon needs hardened molds or it eats the molds up.

A very very very simple arm rest mold for a car is around 15-20 gs and thats with a 6mm tol. You wantto hold .1 well triple that and so on. Plus there is a lot more to injection molding then just a mold. Most times that the cheapest part of the operation. Idk who your getting your figures from but chances are they won't be in business long.
Not trying to be negative here just offering a little perspective.
He'll I wouldn't even design your mold for 1500 let alone build it.
Very curious to how they are able to do this. Hope you share someday

Plastic mag pump inserts that fit in a steel outer housing would work. Isn't that how seadoo does theirs?

What about a reasonably priced waterproof total loss enclosure?

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.

We have had a couple molds made over seas. You might be suprised at the quality of some of the molds coming out of china. You get what you pay for.

I could make a kick ass mold for 1500. but i would be doing all the labor for free!:fingersx:

And designing it and programming it for for free. If you going to make a quality mold you need quality material and tooling to machine it. 1500 doesn't last very long. Plus a spc/warp fixture to gather statistical data to fix any warpage issues. There's just a lot to building a quality part. It doesn't stop with a mold. The whole process needs to be engineered.

Interesting. As a degree'd plastic engineer I applaud your ideas; however resin selection, gating location and part design are very big factors to a successful product. Good Luck!

Well since im a mold maker at a plastic injection company its no problem to do any of that. 1500 would cover matrials and tooling for a smal/medium mold.

how about a 4 gal fuel tank made to fit around a power factor pipe... so we don't need to run these 2 gallon tanks

Agreed I really didn't want to come off as some know'it'all cause I am not by any means. No disrespect implied to the op or you. I'm sure you could have a fairly large tolerance on a ski part like f/a and e boxes and not get murdered by warped parts. I'm just accustomed to working with a very small window of error and it's jaded me overtime.
I think everything should be within .05mm lol

I was told to look into having my molds made in CHINA also

It's a thing that I don't like to see done but with only me and one other machinist some times we got to do it. Some of there molds we have gotten are awesome and some are not worth the metal there made out of. Again you
Get what you pay for.

The company I work for has most plastic parts made in China...some of the parts are glass-filled plastic overmolded on ceramic...and key dimensions are held to 0.005mm. It's unbelievable...but no, those aren't $1500 molds. Someone with 30+ years experience on this side is overseeing everything and doing the engineering. These are parts that we've literally made millions of.

Just design a whole new ebox, the yamaha one is :):):):)ing junk. Yamaha makes some good stuff, but they also make some stuff that makes you wonder who in the hell thought it would be a good idea.

How about a 1 size fits all bullet proof last when you will ever buy flame arrestor...for the guys that can't run OEM.

You could dominate the market over the complete garbage that is out there now.

I'm making a glass'd custom flame arrestor for my build because of nothing else fitting (lowered to the xtreeeme hood) - so MADMAT's idea is appealing to me at least! Some type of interchangeable bottom plate for dual carb setup's would be ideal - so you could adapt a one side fits all upper box assembly to any intake plate, to accomodate for differing carb hole patters or distance to centers. I'd be willing to help on the design!
