The problem with the injection molding idea is quantity The molds are not cheap For a 1/6th scale hull you are probably looking at a 25 thousand dollar mold
Then you have to find a shop willing to run your mold for only a few thousand pieces which is really 2 days production time tops A track mold would be a multi cavity dead with probably 16+ cavities(assuming you don't have the hinge pin holes molded in) all on a part tree. And again you're looking at a very short manufacturing run for 10k pieces. Lemme look into the feasibility of having the parts laser cut into a flat piece kit form using like 1/ Sent via BlackBerry from T-Mobile -----Original Message----- From: Mike Mangus <[email protected]> Sender: [email protected] Date: Wed, 2 Nov 2011 13:28:54 To: [email protected]<[email protected]> Reply-To: [email protected] Subject: Re: [TANKS] track talk It would be awesome if there was a company that could make injection-molded fiber-filled plastic tracks. They could pop a few thousand out at a time. heh. Has anyone thought of injection molded hulls or tanks as a possible lower cost or less time consuming option to get more people into tanking? I know the plastics will hold up to the abuse.

We've had no problem making tread parts for multiple tanks with a single 8 tread mold. Regarding set time: It doesn't take long to pour resin into 6-8 molds. Once you've learned the process (spray, measure, dye, mix, pour, pop) things go pretty smoothly. > I'm leaning toward molding and casting myself, but I like Franks offer > of "prototype parts for molds".

Together, we can form the un-holy trinity of mold making :-) Frank P. -- You are currently subscribed to the "R/C Tank Combat" group.
