Company Summary

In 1989, Jesse Alvarado started a machining business in his garage with just one machine. Over 25 years later, that garage shop has evolved into a 3600 SQ FT machine shop complete with 15 CNCs and an office for Administration and Metrology. Located in Lancaster, California (60mi north of Los Angeles), we’ve done work for various Military projects, as well as commercial and aerospace projects.
