Welcome to Moo's Machine Works!

Welcome to Moo's Machine Works! We have been proudly serving Hawai’i since 1983. Our machine shop provides full service machining, fabrication, and hydraulic services. We are located in Mapunapuna (right off Nimitz), which is convenient to commute from all sides of the island.

As one of largest machine shops on the island (roughly 41,000 square feet), we are able to house numerous trucks, trailers, and heavy construction equipment all at once. With our vast space, we stock raw material in standard and metric sizes, such as: solid cold roll, solid hot roll, pipe, tubing, channels, angles, flat bars, plates, key stock, etc. We have these in all types of material, including: steel, aluminum, chrome, bronze, stainless steel, UHMW, aqua met, etc.

We currently have the largest hydraulic seal stock on the island. We stock metric and standard seals, as well as full kits for numerous brands. Even if the equipment is in “dinosaur” status, we can help you! Our family of technicians include: machinists, welder/fabricators, mechanics, and hydraulic specialists. Many of our workers are “old school” and have been with us since the start of our company. Our knowledgeable staff and technicians can help you design and make what exactly you are looking for, so don’t hesitate to call us at the number listed above!
