Injection molding gear is so different with machining gear. besides using involute gear compared to deliver, these two gear have almost no other common. The two kinds of
gear has essential difference. machining gear be cutted to the predetermined size by particular gear machine tool that design for a particular task. Injection molding gear is moulded in gear cavity. this cavity usually be produced by EDMs. The size of gears cavity can ensure the Injection molding gear have the right size after cooling.
Millions of injection molding gear can be worked out by using a gear cavity.
