Miniature Plastic Gears
Miniature Plastic Gears
(OP)
I am in the process of designing a compound geartrain for an autofocus mechanism. To keep size and cost down, I am planning on using plastic for all gears. Each gear will have a pitch diameter of no more than .25" and a thickness of no more than .050". I'm planning on a diametral pitch of either 80 or 100. All of these gears will be custom injection molded.
Does anyone know where I can have prototypes of such gears made? I've thought about SLAs, but I'm not sure if such fine features can be produced using this process.
Also, does anyone have any suggestions on manufacturers that could have the experience to injection mold such gears for production? My current thinking is that farming these parts out to Asia makes the most economic sense, but I'm still uncomfortable with the drawbacks of not having a supplier I can actually communicate with.
Any other advice or tips on designing a gear train with miniature plastic gears would be appreciated.

there are a lot of choices for help out thier. Molders include ABA/PGT,UFE, and Winzler. You can also talk to the plastic Resin People. Ticona ,Dupont, DSM and so on.
Good Luck
