Folks,
I have been working on reproducing a sunroof gear for about a year now and I think I can finally make the numbers work. I can make it on my plastic injection machine using glass filled delrin which should be harder than anything that I have tried before. As some of you know I attempted to make the gear by casting it and injecting the mold with resin. The best I was able to do lasted a week. Using my injection machine with delrin, would make the gear last a lifetime. This is the best way to do this part that I know of. The cost of the molds has always been the problem for this gear. Because of the straight teeth and the angled teeth, the mold base is very costly. I need to be able to get a sense of how many gears I can move at $65/each. Again, because of the costs involved, buying 20 will not get you a discount. This will be the cost per gear.
Finally, the last thing that I need will be to borrow a gear to get the proper size done correctly. I returned the gear that I used to use to make the first casts. When I made that gear, the method didn't take into account for shrinkage. So, I don't have a gear the actual size which is obviously very important.
To the person that lends me the original, I will gladly return the gear plus a new one.
All of my parts are made to last or I will refund your money. End of statement.
Thanks for your feedback. I will check back in to this post to see the response and gauge the need. This is not in any way commiting you to buying one. I just need to see the volume one more time. Once started, the turn around time will be about two months.
