Working with MJM Manufacturing has been one of the best vendor experiences I've had. The parts matched my samples perfectly, and even the packing was done with real care — clean, organized, and professional. Of all the vendors I've worked with, they're by far the most organized and quality-focused. Great communication from start to finish. Highly recommend them for custom fabrication work.

As a customer, I have been working with MJM Manufacturing for approximately 35 years. The expertise of Mike Mijares and his team at MJM is top notch. Whenever I have a new part design, I typically review the design of the part with MJM to ensure that I am using the most cost-efficient manufacturing process to produce the parts as economically as possible. There was a part that we had made years ago using a progressive die to emboss a curved channel into a sheet metal part. The cost of the progressive die for this part was $55K. The redesign of the part from MJM consisted of $1200 in tooling to make the new part profile. Parts came out great and saved tens of thousands in tooling. Lastly, whether MJM produces a prototype or a production run, the appearance of the part is pristine, no tool marks or scratches on any part. In the 35 years that I have worked with Mike and his team, I have found them to be one big family. Mike’s love for his business is refreshing! You rarely see a person that is so charged to get up for work every day! Richard Havass Mechanical Engineering Manager JCI-Sensormatic
