Initially focused on the manufacture of tooling and accessories for the Davenport screw machine, Mr. Brinkman pioneered the development of the pneumatic thread-rolling attachment. At the same time, CJWinter also began to expand its product offerings to include a complete line of thread-rolling dies both for its own attachment as well as for those from other manufacturers.

Today, CJWinter is one of the world’s leading manufacturers of cold-displacement, cylindrical dies and attachments. CJWinter’s products are found in traditional thread-rolling applications such as those used with multi-spindle screw machines, rotary transfer machines and CNC – lathes.
