What Electro-Prep does
Electro-Prep, Inc. is a privately held, family-owned contract manufacturer founded in 1977 and headquartered in Wareham, Massachusetts, specializing in custom wire harnesses, cable assemblies, ribbon cables, coaxial and Ethernet cables, multi-conductor cables, IDC connectors, and complete box-build / electro-mechanical assemblies. The company operates from a 10,000-square-foot manufacturing facility equipped with computer-controlled cut-and-strip machines (Schleuniger), automated test systems (Cirrus), and semi-automatic tooling from TE, Molex, and related vendors, supporting in-house cutting, stripping, crimping, soldering, splicing, terminating, and 100% continuity testing. The workforce is certified to IPC/WHMA-A-620 and J-STD-001 standards with an in-house certified trainer.
The company serves regulated, mission-critical end markets — primarily military and government (MIL-SPEC, ITAR-registered) and medical instrumentation (biocompatible assemblies for defibrillators, surgical robotics, patient monitoring) — with secondary exposure to industrial, water purification, marine, and commercial customers. Customer engagement is B2B direct sales: enterprise customers submit specifications via the company website, receive quotes typically within 48 hours, and receive product within 2-5 weeks. Pricing is quote-based with both turnkey (Electro-Prep-purchased materials) and consignment (customer-supplied materials) options; engineering services for product design, reverse engineering, and documentation are offered alongside manufacturing.
Electro-Prep is ISO 9001:2015 certified, UL and CSA listed, ROHS and MIL-SPEC compliant, and ITAR registered. Reported customer outcomes include 99th-percentile quality audit ratings, multi-decade customer relationships (one dating to 1992), and a customer-approved dock-to-stock program. The company markets primarily through content (case studies, eBooks, technical publications, blog, video) and is bootstrapped with no disclosed external funding, partnerships, or ownership changes on record.
