What Sets Us Apart

Six Reasons Engineers Choose MJM

When you need precision sheet metal fabrication with zero margin for error, the partner you choose matters.

01

Fully Integrated Under One Roof

Laser cutting, CNC turret punching, forming, welding, machining, powder coating, silk screening, plating, and assembly — all in our 44,000 sq ft Miami Gardens facility. No subcontracting. Your project goes blueprint to finished product without leaving our building. See all fabrication services.

02

17 Independent Certifications

MJM holds 17 independent certifications including AS9100, ISO 9001, ITAR registration, DBE certification, MIL-I-45208A, and minority-owned small business certifications. CAGE Code 0YLX1 — registered on SAM.gov. View all certifications and registrations.

03

ITAR Registered & Defense Compliant

MJM is ITAR registered with long-standing relationships across aerospace and defense — Boeing, Lockheed Martin, Northrop Grumman, BAE Systems, and L3 Harris — all requiring strict compliance, controlled environments, and documented traceability.

04

24–48 Hour Quote Turnaround

Engineering teams don’t have time to wait a week for a quote. MJM provides computerized quoting, scheduling, and tracking with a 24 to 48 hour turnaround. Our engineering department reviews your drawings and responds fast with accurate pricing. Request a quote.

05

Prototype Through Full Production

Whether you need a single prototype or a full production run of thousands of units, MJM supports the entire manufacturing lifecycle. Many clients start with a prototype and stay for decades — our staff includes employees with 45+ years at MJM.

06

47 Years. Made in USA. Miami-Built.

Founded in 1979 by Mike Mijares in a two-car garage, MJM has never moved offshore. Every part is fabricated in Miami, Florida by skilled American workers. When domestic sourcing or Buy American provisions matter — MJM has been the answer since 1979.

Total Landed Cost

Why Nationwide OEMs Source From Florida

When buyers on the West Coast or in the Northeast evaluate a Florida fabrication partner, the first objection is usually freight: “Isn’t it more expensive to ship parts across the country?” It’s a reasonable question — but freight is only one line item, and rarely the one that decides total cost.

The real cost of a fabricated part is driven by labor, manufacturing overhead, equipment efficiency, material utilization, and production capacity — and those costs vary dramatically by region. For precision sheet metal work, skilled labor is a major component of every part: CNC laser operators, press brake operators, TIG and MIG welders, CNC machinists, programmers, assembly technicians, and quality inspectors all factor into a shop’s hourly rate.

California and other high-cost regions carry structurally higher costs across the board — higher wages, higher workers’ compensation, higher facility and energy costs, the nation’s highest state income tax, and heavier regulatory overhead. Florida remains one of the most competitive manufacturing labor markets in the country, with no state income tax and a lower overall cost base. That difference is built into every quoted hour — and on a medium-to-large fabrication project, it frequently exceeds the cost of freight.

Cost Component High-Cost Region MJM (South Florida)
Skilled Labor (welding, laser, press brake) Higher Lower
Facility & Energy Cost Much Higher Lower
Workers’ Compensation Higher Lower
State Income Tax & Regulatory Overhead Higher None / Lower
Freight to Customer Minimal Added
Total Landed Cost Often Higher Often Lower

This is why many California, Texas, and Northeast OEMs source precision fabrication from Florida and the Southeast: even with freight added, the total landed cost is frequently lower — without giving up quality or speed. At MJM, that competitive cost comes packaged with capabilities coastal buyers don’t always find close to home:

• Competitive total landed cost, not just a low freight line
• Lower manufacturing overhead than most coastal markets
• High-capacity automated laser cutting — five Amada systems running simultaneously
AS9100 certified and ITAR registered quality systems
• Decades of national shipping experience
• Faster lead times thanks to available capacity
• Single-source fabrication, welding, machining, and finishing under one roof

Before you assume the closest shop is the most cost-effective one, let us quote it. Send your drawings to info@mjmmfg.com and we’ll give you an all-in number so you can compare total landed cost — not just freight.
