The invention relates to motionless mixers and baffles thereof and includes a baffle having a pair of substantially symmetric opposing major surfaces generally helically twisted along a central longitudinal axis of the baffle and a first substantially planar surface connecting the pair of major surfaces at one end of the baffle, the first planar surface extending both substantially transversely and substntially parallel to the central longitudinal axis. The intersection of the first planar surface and one of the major surfaces forms a knife-like edge at the one end of the baffle. Similar additional knife-like edges can be provided, a second knife-like edge on the one end of the baffle radially disposed on opposite sides of each of a pair of axes through a central longitudinal axis of the baffle to form leading edges of the baffle and a like pair of knife-like trailing edges on an opposite end of the baffle. Such geometry enables a plurality of the baffles to be formed as a single insert unit by conventional injection molding techniques using only a pair of mold halves.

A motionless mixer baffle member having opposed major surfaces and first and second ends, said baffle member being helically twisted symmetrically about a longitudinal axis and being defined by said opposed major surfaces extending along said axis from said first end to said second end of said baffle, said major surfaces being connected together at said first end by a substantially planar surface extending substantially transversely of said axis and lying in a plane substantially parallel to said axis.
