Custom Wire Technologies Inc. supplies medical device makers with miniaturized wire assemblies

There are several well-known wire winding and distributing companies in the metro Milwaukee area. However, only one of them makes components using wire that is less than one-fourth the diameter of a human hair.

Custom Wire Technologies Inc., a Port Washington-based manufacturer of coiled wire products, makes components that are used in medical devices and other medical-related activities.

“These are things that are being put into and taken out of the body during a patient’s stay in a hospital,” said Bob Boldig, owner and president of the company. “A lot of them are some form or reinforced tube set used surgically to feed people or some form of catheterization.”

The assemblies made by Custom Wire Technologies are small. Workers routinely use magnification equipment during assembly in the company’s clean room area. The company’s coiled assemblies range in diameter from 5/8 of an inch to .009 of an inch.

“Everything is being pushed smaller and smaller today,” Boldig said. “We work with some stuff that is less than .003 of an inch in diameter. (Wire) that is four times the diameter of a human hair is the biggest stuff that we’re working with.”
