Composites

Leading composite manufacturing specialists use high-performance pultrusion dies manufactured by Dearborn, Inc.

Many of the leaders in the pultrusion industry are currently using dies manufactured by Dearborn, Inc.

These dies are regularly used to pull a variety of materials including polyester, vinylester and various epoxy resins. The tight uniform bore sizes, hard chrome plating, and highly polished micro finishes are all required by our customers that regularly pull high ratio glass mixes.

Dearborn retains a competitive edge with our pultrusion dies because of:

Tight uniform bore size through the entire length of the die (ie, +/-.0005 on ID size) Higher pull rates due to consistent ID sizes and superior surface finishes
Surface finishes better than 10 RMS through the OAL Dies produced are well suited for high-ratio glass mixtures
Chrome plated and Ion nitrided finishes available Dearborn uses the same strict inspection criteria as is used for our Navy nuclear and aerospace applications

Material that we typically machine for the pultrusion applications include:

Alloy steels P-20, 4140
Stainless steel 304
